Caution

Knauf systems may only be used for the application cases as stated in the Knauf documentation. In case third-party products or components are used, they must be recommended or approved by Knauf. Flawless application of products / systems assumes proper transport, storage, assembly, installation and maintenance.

General instructionsBuilding physics requirements must be examined and tested in detail.Thermal bridges must be avoided, see DIN 4108 amendment 2.The assessment of the thermal insulation shall be performed in accordance with DIN 4108-2 and EnEV (German energy saving ordinance).The structural stability of the existing wall must be assured before installation of ETICS. The proof must include all load-bearing and associated elements.Special care must be taken, particularly with the application of the connections.

TermsSplash water zoneThe splash water zone starts with the edge of the ground line or top edge of the covering and has a height of at least 300 mm and generally up to 600 mm. Water from precipitation must be diverted away by constructional measures (gravel bed or layer that interrupts capillary action). Paving stone or paving must be installed with the corresponding slope away from the building and be constructionally separated from the building. Observe the DIN 18533.Explanation of termsIn this system data sheet, the following terms that diverge from the system approvals are used:

IntroductionSystem overview

Knauf WARM WALL Basis in timber construction with insulation materials made of EPSKnauf WARM WALL Basis is a building authority approved external thermal insulation composite system (ETICS) with insulation materials made of expanded polystyrene (EPS) for new and old buildings. The façade insulation panels are either adhesively bonded to the substrate or additional dowels are applied in addition to adhesive. The panels have end to end joints or a tongue and groove on the long edge. The latter guarantee a safe and fast insulation panel bond with a flat surface. The mortar pocket on the rear avoids thermal bridges as the adhesive does not get into the insulation panel joints. The WARM WALL Basis system can be employed as a not easily flammable system up to the high-rise building limit (determination of the building height is dependent on the respective applicable state building code).Properties

■ Reaction to fire of ETICS depending on the version is not easily flammable (building material class B1) or flammable (building material class B2), refer to table page 14

■ Insulation material thickness: permissible up to maximum 400 mm ■ Sound insulation: With enhanced requirements, the use of elastified insulation materials (EPSe) in conjunction with thick layer plaster systems is recommended

From the table, you can read off the thermal conductivity as well as the total thickness of the insulation material of the thermal resistance R using the rated value. The sum of all thermal resistances (plaster, masonry, insulation materials, etc.) is added to the sum of the 0.17 (m²∙K)/W of both thermal transfer resistances for interior and exterior and delivers the thermal transmission resistance. The inverse value of the thermal transmission resistance is the U value.

Additional fire breakAn additional fire break is required as the uppermost connection of the ETICS at the transition to the combustible construction products (e.g. roof) at a maximum of 1 m underneath the adjacent combustible construction product. The material corresponds with that of the plinth fire break. The fire break is adhesively bonded along the entire surface with a mineral-based adhesive. Additional dowelling under the mesh is not required with an adhesively bonded system. Dowelling is always required with an adhesively bonded and dowelled system.

Design of the fire break against room fire ■ Consider fire protection measures against a room fire above the fire break at the height of the ceiling of the 3rd storey (see scheme drawings on page 16 to 17); as the resulting fire resistance measures necessary against a plinth fire extend from the plinth to above the 3rd storey, and they include a room fire

■ Horizontally arranged fire breaks made of MW Volamit 040 (mineral wool lamella) or MW Brandriegel 035 plus fire break must be circumferentially installed around the building as a full surface adhesively bonded configuration on at least every second storey.

■ If dowelling is required for the system (see page 26), the circumferential and full surface adhesively bonded fire breaks are dowelled in each element with 2 dowels fitted in the centre at a spacing of 60 cm under the mesh ▪ MW Volamit 040: Dowel with additional Dübeltellern DT 140 dowel

■ If the system is only adhesively bonded, fire breaks made of MW Volamit 040 are only adhesively bonded on the full surface and fire breaks made of MW Brandriegel 035 plus fire break require additional dowelling.

■ Edge areas located directly at openings require an additional reinforcement with Gewebeeckwinkel (mesh corner angles)

Definition of stories

Stories above ground acc. to clause 2 (6) of the German Model Building Code (MBO).Cellar levels, where the mean cellar ceiling does not extend more than 1.40 metres above ground level, shall not be considered as a floor level (storey), as well as hollow areas (jamb walls) between the top floor and the roofing that cannot be used as common rooms.The height specifications can diverge from one another in the different state building codes.

Two-storey building

On low height buildings (0 – 7 m, see also page 13), possibly excluding special constructions, no additional fire protection measures are required from the point of view of the building codes. In case the ETICS are still to be not easily flammable in design, additional fire protection measures against plinth fire as well as an additional fire break on the connection to the combustible construction products (e.g. roof) are required. Fire protection measures against room fire are already incorporated due to the building height.

Three-storey building

It is recommended that ETICS on buildings of classes 1 to 3 that are a maximum of three stories should be not easily flammable in their design. This necessitates the application of fire protection measures against a plinth fire as well as an additional fire break at the connection to combustible construction products (e.g. roof). These already cover fire protection measures against room fire due to the building height.

Different building section heights

On building sections of different heights, the position of the fire break must be planned so that the fire break is at the same height in all parts of the building. Offsets up to a height of 1 m can be negotiated with an "upward" or "downward" offset. Alternatively possible is a complete fire protection related separation of the ETICS in the joint area of both buildings by a vertical and continuous fire break.

Offset exterior wall openings

Exterior wall openings on façades are not always located at the same height and do not always have the same size. Downward offsetRetention of the maximum clearance of 0.5 m above the lintel with windows installed below it can be ensured by a local "downward offset" of the fire break.Upward offsetIn cases where the openings are directly in the horizontal path of the fire break, the fire break must be offset upwards around the opening. The height of the offset must be limited to 1 m.

Continuous strip windows, individual openings

Continuous strip windows on a building that horizontally interrupt the applied ETICS can assume the function of a fire break in the room fire protection zone (insulation material thickness t > 100 mm). Additional inclusion of fire breaks above the continuous strip windows can be therefore omitted. The vertical reveal to which the fire break is joined in the lintel area must be insulated along the entire height with mineral wool. The opening in the structural element for the strip window must have a minimum height of 1 m.Individual openings on each floor, e.g. doors, circumferential fire break, do not require a circumferential fire break. Rather, the fire break must first be continued into the reveal and then continued at the same height.An upper additional fire break is only required at the transition to combustible roof constructions.

Multi-storey, glazed stairwells

If a building features a fire protection staircase acc. to clause 35 of the German Model Building Code (MBO) with cross-floor, multi-storey glazing, the cross-floor "exterior wall" openings must be fully surrounded along the perimeter with mineral wool strips at a minimum width of 200 mm in the same way as the fire break.


Balconies, loggias and access galleries

Exterior areas that project out from the façade, such as slabs from balconies and access galleries and that interrupt the fully horizontal ETICS, assume the function of a fire stop, so that the additional inclusion of fire breaks in this area is unnecessary. The fire break must connect to the side at the level of the cantilever slab. The cantilever slabs must be solid and mineral-based and at least fire resistant (F30 acc. to DIN 4102-2 or alt. REI 30 acc. to EN 13501-2). The cantilever slabs must connect completely to the exterior wall without a gap or with load bearing thermal insulation elements (e.g. ISO-Korbs), that are fire resistance rated (min. F30 acc. to DIN 4102-2 or alt. REI 30 acc. to EN 13501-2, connected with the exterior wall. Otherwise the fire break should be continued preferably under the cantilever slab.


Offsets in the vicinity of the cantilever slabs

With offset ≤ 1 mIf a direct horizontal path for the fire break and cantilever slab is not possible, connection to the side is possible by an upward and downward offset.With offset > 1 mIf the fire break cannot be directly connected to the side of the cantilever slab, or if the cantilever slab as a fire break cannot be used due to the lack of a fire resistance class, the fire break should be continued preferably under the cantilever slab.If continuation of the fire break under the cantilever slab is not possible, e.g. due to an existing roller blind cassette, a non-combustible fire protection board that is at least 10 mm thick can be adhesively bonded and dowelled to the lower side of the cantilever slab in order to achieve the protective objective.

Sloping site

If the façade surfaces are at differing heights, e.g. on slopes, it may be useful to consider the sides of the building separately for fire protection purposes. This can be archived by a fire break that is implemented vertically along the entire height of the building at a spacing of maximum 1 m from the outer corner of the building. On the surfaces separated from one another the respective fire protection measures against a plinth fire, and if necessary, against a room fire must be implemented. On the building sides located in sloped sites, it is necessary to evaluate whether there are areas with an increased fire load. The fire protection measures must be planned accordingly.

The corresponding additional fire break is only required at the transition to combustible roofs.

Mixed façades

On mixed façades where different façade systems are applied (ETICS, back-ventilated curtain walls, facing masonry, etc.) adjacent to one another, it is possible that the fire can spread to the ETICS from the adjacent façade system. To prevent the spread of fire to the ETICS, areas of the ETICS must be protected continuously by horizontal fire breaks or vertical fire breaks and be separated from other façade systems.

Dowel ratingMethod for determination of wind loadsPractice-based methodSuitable for all building types up to a maximum height of 25 m in wind zones 1 to 3 (Recommended by the German association Fachverband Wärmedämm-Verbundsysteme e. V. in conjunction with the DIBt).Simplified methodIn accordance with EN 1991-1-4 and EN 1991-1-4/NA, the simplified method can be used for a building up to a height of 25 m provided that it is situated on flat terrain up to a height of 800 m above sea level. The height / width ratio must be ≤ 2. The dowel rating acc. to the simplified method is shown on pages 26 to 29. Standard methodIn case of buildings in wind zone 4 and / or buildings exceeding 25 m in height, for disjointed floor layouts or a ratio of height / width > 2, the standard method in acc. to EN 1991-1-4 and EN 1991-1-4/NA must be used.

NoteDowel extraction tests will be necessary for dowelling on non-standardized substrates. The basis for the listed rating tables in accordance with the simplified method is the corresponding specified characteristic dowel load bearing capacity (dowel load capacity) NRk. Should the load bearing capacity be lower, an individual rating of the basis of the EN 1991-1-4 and EN 1991-1-4/NA will be required.

Installation and applicationPreconditions I Machine technology

PreconditionsAll connections and detail features must be clarified before application.The necessary substrate preparation must be undertaken on a case-by-case basis and must be described in full detail in the tender specifications. Substrate tests and possible measures are listed in this System Data Sheet on page 39.The surface of the substrate must be dry, even and free of grease and dust as well as free of any residual substances that may reduce the adhesion. Check the stability of existing coatings (paint coatings and old plasters) and compatibility with adhesive, and remove unstable coatings completely if necessary.Rising damp may not be present. All applied connections must be driving-rain proof. Ensure that all openings (interface gaps) are sealed.The internal plastering and screed works should be completed and the components should be dry enough so that an excessive accumulation of moisture is avoided.

The contractor is solely responsible for inspecting the condition of the substrate and the on-site conditions.The ambient temperature, substrate and material temperature must be at least +5 °C and may not exceed +30 °C during the entire application, drying and setting phase (if Kati is used as a finishing coat, at least +8 °C).Unfavourable weather influences such as high temperatures, wind or direct sunlight can change the application conditions. In case grey insulation panels are used it is necessary to provide sufficient shading, e.g. by provision of nets on the scaffolding until the basecoat is applied.Only cold, clean water (drinking water quality) may be used as mixing water.Water up to a temperature of +30 °C may be used on building sites in spring and autumn.Cover or apply a watertight covering to easily-soiled building components (e.g. window sills) prior to application. Protect surfaces from precipitation and direct sunlight.

Installation and applicationSubstrate inspection and preparation

Substrate inspection and preparationThe surface of the wall must be flat, dry and free of grease and dust. In case coatings (e.g. Paint coats) are applied to the substrate, it is necessary to professionally assess their compatibility with the adhesive.Unevenness in the substrate up to a maximum of 20 mm can be covered with the adhesive if dowelling is used in addition to adhesive bonding, and with exclusive adhesively bonded systems this value is a maximum of 10 mm. Major unevenness should be equalized using a suitable plaster layer or by staggering the insulation panel thickness. The bond strength of the plaster should be tested after it has set.Substrate inspection and preparation for adhesive application of ETICS

When configured as a not easily flammable ETICS and the associated observance of the plinth fire protection zone, the plinth insulation panels can be applied up to a height of 0.9 m above the edge of the ground line. Adhesively bond plinth insulation panels with adhesive on mineral or bituminous waterproofing of buildings. The adhesive application is across the entire surface or using an edge ribbon and dab bonding method with an adhesive surface of at least 40 %. The lower edge of the plinth insulation panel must have a continuous strip applied at least 50 mm wide. The lower edge of the plinth insulation panel can be cut off with a minimal integration depth in the soil, in case of insulation material thicknesses exceeding 140 mm it can be slanted. Allow a setting time of at least 48 hours before continuing work.Adhesive bonding on bituminous substratesIn case of mineral adhesives (not necessary with Sockel-SM Pro), apply Sockel-Dicht on two component, bituminous substrates as a bonding layer and roughen the surface with a broom. Allow to dry and set fully before continuing.Insulation material from 150 mm above the edge of the ground line requires additional dowels (with the exception of full surface bonding with Sockel-SM Pro).

Notes

For further information on the installation and application of insulation panels and plaster system in the plinth area see pages 41 to 50.Observe the “Façade plinth render/External components” (German only), issued by Fachverband der Stuckateure für Ausbau und Fassade Baden-Württemberg, as well as the DIN 18533.

Insulation panels applicationInstall the plinth connection end profile horizontally and fix using anchor nails at spacings of approx. 300 mm. Compensate for substrate tolerances with washers. Connect the joints and the plinth connection end profiles with H connectors. Provide the outside corners with the appropriate mitring. Push on plinth profile made of plastic with drip edge and integrated reinforcement mesh strips on the plinth connection end profile ensuring joint offsetting to the insulation panel and plinth connection end profile.When connecting perimeter/plinth insulation to existing ETICS or when using a plinth connection end profile, a joint sealing tape FD is inserted between the perimeter/plinth insulation panel and plinth connection end profile. This is unnecessary of the ETICS are applied in conjunction with a Sockel-Abschlussprofil Peri plinth profile on an existing perimeter/plinth insulation. Peri is inserted between the perimeter insulation and the adhesively bonded insulation panel (see page 46).Apply insulation panels immediately to the fresh adhesive by pushing, floating and pressing.



Apply the insulation panels precisely and continuously starting from the bottom with the joints staggered at ≥ 100 mm (half panel length recommended for joint staggering). Cross joints, e.g. on opening corners should be avoided.Bonding of the insulation panels up to a thickness of 200 mm is possible without corner grooving, however, with more than 220 mm adhesive bonding with corner grooving is required.Adhesive may not be applied to the insulation panel joints. Open panel joints up to 5 mm in width can be filled with B1 foam, panel joints > 5 mm or skips can be cleanly sealed using equivalent insulation panel strips.It is recommended that the upper and lower edges of the insulation surface have a continuous strip of adhesive applied to ensure that back ventilation is excluded.Allow a setting time of at least 48 hours before continuing work.Corner configurationUp to 200 mm without corner grooving

Insulation panel dowellingThe wall must be sufficiently stable to allow the use of dowels.If insulation panels are to be fastened to ensure structural compliance, the certified dowels must be used (see page 26 to 29).Dowel extraction tests are necessary for substrates not stipulated in the respective dowel certifications, or should the characteristics of the substrate be unknown.The number of dowels can be taken from the tables on page 28 or the approval Z-33.43-82. The wind load can be determined with the simplified method (page 26 to 27) or acc. to EN 1991-1-4 and EN 1991-1-4/NA.Application of the dowels can commence after the adhesive has hardened sufficiently. The diameter of the drill must be ≥ 8 mm.Do not use impact or hammer drills on hollow or perforated bricks or masonry. Arrange the drill holes so that the concrete reinforcement is not damaged. Drill hole depth = dowel length + 10 mm (or +25 mm with recessed dowel installation). Clean the drill holes before the dowels are applied.Do not use worn drill bits. Resharpening of the drill bit is not permissible.Under the mesh the installation can be flush to the surface or recessed in the surface. When applying dowels through the reinforcement mesh the dowels can only be placed surface flush. The dowel must be set in the fresh basecoat layer after the application of the basecoat and the embedding of the reinforcing mesh. Then immediately (wet plaster on wet plaster) apply a second layer of basecoat.The substrate temperature must be ≥ 0 °C when placing a dowel. The exposure to UV light with direct exposure to sunlight for the dowel and insulation panel may not exceed 6 weeks.

Note For dowel rating and selection see page 26 to 29

Plinth and splash water zoneApply additional constructional, mechanical fixing of the plinth insulation panels from a height of 150 mm measured above the edge of the ground line, e.g. for bituminous or painted substrates with general building authority approved dowels with a dowel plate diameter 60 mm (2 dowels per panel).

Use of adhesively bonded window connection profilesAn adhesive bonding test must be performed before the use of adhesively bonded window connection profiles. For this purpose, clean a concealed location with a clean and dry cloth (without cleaning agent). The substrate should be level, dry and dust-free. Residues that can affect bonding must be removed. The temperature must be between +5 °C and +40 °C. Cut off a short section of the profile (approx. 10 cm), peel off the protective paper of the Sk-PE-Dichtband sealing tape and push the profile section firmly on. Wait 10 minutes and then tear the profile with force away from the substrate. The Sk-PE-Dichtband sealing tape must on the one hand remain completely attached to the profile and on the other hand completely to the substrate (continuous foam rupture). Thus the substrate is suitable for adhesive bonding.Should this not be the case, the window connection profile Universal Pro or Universal-K Pro with PUR sealing tape must be used.

Reinforcement layer (continued)Fully embed strips of reinforcement mesh or Gewebeeckwinkel Sturzecke mesh corner angle for lintel corner at the inner corners between the window reveal and window lintel in the basecoat. Subsequently apply Gewebeeckwinkel mesh corner angles perpendicular and flush. Apply the reinforcement layer and level it.Except when using Gewebeeckwinkel Sturzecke mesh corner angle for lintel corner, extending diagonally from all opening corners embed Gewebeeckpfeile mesh corner arrows or approx. 300 x 500 mm strips of reinforcement mesh in the wet mortar.Subsequently embed Armiergewebe reinforcement mesh on the entire surface with at least a joint overlap of 100 mm fresh-in-fresh in the basecoat layer. Apply a full covering of basecoat to the mesh. The mesh is arranged in the centre when the basecoat thickness is up to 4 mm, for > 4 to 7 mm layer thickness it is in the upper half of the basecoat layer and for > 7 mm in the exterior third.For scratch render the layer thickness of SM300 must be 7 mm. On the reinforcing mesh, apply minimum 2 to 3 mm of SM300 and after initial setting roughen the surface horizontally with a brush.If a double reinforcement is necessary (see table on page 45), the lower reinforcing mesh is applied with a respective overlap of approx 100 mm in the first basecoat layer of 2 to 3 mm without creases. After the basecoat layer has hardened, the second basecoat mesh is embedded with a joint overlap of ≥ 100 mm and a joint overlap of the second mesh to one another of ≥ 100 mm in the second layer of the basecoat. The position of the second mesh corresponds to the position of a simple reinforcement with a mesh. Alternatively, the second reinforcement layer can also be applied onto the fresh first reinforcement layer. For this purpose, apply basecoat as wet plaster on wet plaster onto the first basecoat layer and apply reinforcement mesh with staggered joints. The diagonal reinforcements are embedded before the second mesh layer.Avoid excessive smoothing of the reinforcement layer to prevent a concentration of fine particles or formation of a sinter layer on the surface.Rub off any burrs that have formed when drying.Plaster connections should be separated with a separating tape, separation strip, profiles or similar from the constructional components.Reinforcement of window lintel / revealImage 1 Dimensions in mm

Basecoat drying timeBefore application of a further coating (primer / basecoat) it is important to ensure that the basecoat is fully dry. The minimum drying time is generally approx. 1 day/mm layer thickness. With Pastol the weather dependent drying time is at least 3 days. With unfavourable weather conditions (e.g. high levels of air humidity or low temperatures) the drying time is extended, e.g. the drying time at +5 °C is around double so long. For further information please refer to the product data sheets of the subsequent coatings.Plinth and splash water zoneApply at least 5 mm basecoat covering the full surface embed reinforcement mesh 4x4 mm or 5x5 mm to the entire surface in the upper third of the basecoat. Stagger the joints by at least 100 mm. When insulation is applied in areas contacting the soil, the reinforcement layer ends about 200 to 300 mm underneath the edge of the ground line.

When reordering, always state the consignment number of the previous delivery.Ensure uniform grain distribution.The type of tool used influences the surface roughness and it is therefore essential to use the same tool for a consistent finish.Ensure that there are sufficient workers available on every scaffolding level to avoid bothersome structural effects. Work quickly fresh in fresh and do not rework hardened surfaces. Avoid work stoppages on continuous surfaces and always complete self-contained areas.Observe Code of Practice no. 26 “Farbveränderungen von Beschichtungen im Außenbereich - Colour changes in exterior coatings” of the Bundesausschuss Farbe und Sachwertschutz (Federal Paint and Property Protection Committee).

Plaster connections should separated from the constructional components with a separating tape, separation strip, profiles or similar.CarraraApply / spray an approx. 5 mm (at least 3 mm on recesses) layer of Carrara onto a continuous surface and spread flush with a straightedge or finish trowel and texture it immediately using the required tool (sponge, trowel, brush, roller, etc.)Noblo FilzApply a fully covering coat of Noblo Filz in grain thickness, allow to dry and then apply a second coat in grain thickness, and immediately sponge / felt, without using water.

The drying time of the basecoat can be reduced to 1 day if the basecoat layer is applied with SM700 Pro. Start sponging or free texturing with initial setting of the SM700 Pro.For surfaces with a trowel finish, apply SM700 Pro in an average layer thickness of 10 mm and create the surface.For surfaces with a broom finish, apply approx. 3 mm SM700 Pro, level and use a coarse broom (with strong coarse bristles) and pull a single stroke through the wet / damp surface.MineralAktiv Scheibenputz and MineralAktiv Scheibenputz Dry floated rendersKnauf MineralAktiv Scheibenputz floated render is applied over the entire surface in grain thickness with a stainless steel trowel, and directly after application it is worked uniformly and without interruption to the desired texture using a hard plastic trowel. Sponge rubber floating produces a coarser more rustic texture finish.Conni S, Addi S, Kati SReady-to-use, paste-like final coat must be mixed thoroughly. When necessary, a small quantity of water may be added to set the application consistence. Apply Conni S, Addi S or Kati S (floated render texture) with a stainless steel trowel in grain size to the entire surface and trowel smooth with circular movements without interruption using a hard plastic trowel.Mak3Apply the scratch render layer of approx. 13 or 14 mm by machine (application by hand only on small surfaces), level with the notched scraper and smoothen with the wide spatula and consolidate (danger of trapped air bubbles). When initial setting commences, possible on the same day but usually on the following day, scratch in circular motions and remove small unevenness's with the scraper. The optimum scratch time is when the grain cracks when scratched. Premature scratching results in a darker colour and unclear structure.Plinth and splash water zoneApply a primer to suit the selected top coat, observe the required drying times. Apply plinth renders, e.g. Sockel-SM Pro or Sockel-SM on the following day on the system-compatible reinforcement layer and sponge.Sockel-SMAfter the top coat in the area contacting the soil has dried, apply moisture protection for the plastered surface with Sockel-Dicht (apply at least 50 mm above the edge of the ground line), which must connect to the building sealing (overlap of approx. 50 to 100 mm) or must be pulled 50 to 100 mm onto the uncoated perimeter insulation panels. Apply in two steps. Minimum layer thickness 2.5 mm.



Sockel-SM ProWhen applying the Sockel-SM Pro render system with a total layer thickness (basecoat and finish coat) of at least 7 mm, additional moisture protection with Sockel-Dicht is unnecessary.ButzAllow a drying time of at least 2 hours before applying Butz on Quarzgrund Pro.Mix the contents of the container well, apply using a stainless steel trowel slightly thicker than the grain size and level in one direction.

Sandstein-DesignSandstein-Design Wandplatte wall panels are applied with Sandstein-Design Kleber adhesive using a notched trowel (6 mm) onto the dry basecoat pretreated with Isogrund, and pressed on uniformly using a Sandstein-Design Werkzeug tool. Directly after application of the Sandstein-Design wall panels, smoothen the existing Sandstein-Design Kleber adhesive in the joints, e.g. using a damp paint brush. Ensure a uniform joint width of recommended 6 to 8 mm. When the Sandstein-Design adhesive is sufficiently dry, apply a generous coating of Sandstein-Design Grund primer to the entire surface. After waiting for at least one further day, apply 2 generous coatings of Sandstein-Design Versiegelung sealing to the entire surface. Protect applied Sandstein-Design wall panels against precipitation until the sealed surface is fully dry.Another coating of sealing can be applied on the following day as protection against graffiti. Depending on the geographic location and climatic conditions, chalking may occur after some time. Regular maintenance is recommended, and if required the façade should be cleaned and primed and then sealed.

Mechanical protection in the plinth areaAs protection for the plinth in the area contacting the soil against mechanical influences of the soil or gravel bed, use of a fleece laminated dimpled sheet up to the edge of the ground line is recommended.

CoatsPrimerAs a primer, e.g. a coat of Grundol is recommended. Façade paintUse a trial coat to ensure the colour shade is correct. Never apply the content from different buckets together on a common wall. Mix the contents together in a clean bucket beforehand. Stir the contents of the bucket thoroughly.The application consistency can be modified in acc. with the Product Data Sheet.Apply a thin and even paint coat crosswise without joints on the fully hardened (generally after 7 days drying time) and dried final coat.Always complete surfaces that can be viewed together on the same day.

Notes

All the products listed here are formulated, so that a preventative and retarding action against soiling is in effect. Permanent protection against soiling caused by microorganisms such as algae and fungus cannot be guaranteed. The susceptibility depends on the local and environmental conditions. Loss of the technical function of the render or coating due to microbial fouling with algae and fungus on the surface is practically non-existent.Observe the Code of Practice "Egalisationsanstriche auf Edelputzen – Farbtonegalisierende Beschichtung - Equalization coats on finishing plasters”, issued by the Industrieverband WerkMörtel e. V.

ImpregnationSuitable impregnation is recommended when using Mak3 in exposed locations and in the vicinity of waterbodies.

Final coat (continued)


UsageMaintenance

Inspect for Technical instructions and measures

Soiling Clean the finish coat or the Sandstein-Design surface using a high-pressure water jet (water temperature below +60 °C, observe the regional wastewater discharge regulations) adapted to the substrate, and if required, apply a new coat of paint to the façade finish coat with a system-conform paint, or apply new primer and sealing to the Sandstein-Design once sufficiently dry.

Microbiological growth (e.g. algae, mould) Clean using a high-pressure water jet (water temperature below +60 °C, observe the regional wastewater discharge regulations) adapted to the substrate, apply Algizid (ready-to-use solution) and clean the finish coat or the Sandstein-Design surface, and if required, apply a new coat of paint to the façade finish coat with a system-conform paint, or apply new primer and sealing to the Sandstein-Design once sufficiently dry.

Sealing of elastic connections (windows, doors, expansion joints, façade penetrations)

Joints applied with permanently-elastic materials are maintenance joints and should be inspected and replaced at regular intervals, if required, or sealed to repel moisture.

Mechanical damage Fill with equivalent insulation materials, reapply the render including the reinforcement mesh, new Sandstein-Design surface with primer and sealing or final coat and if necessary, apply a new coat of paint with a system-conform paint. Repairs to small areas and spots may stand out visually from the rest of the surface. Differences in texture and colour of the finishing coat may be visible.

The recommendations of the ETAG 004 (Guideline for European technical approval of ETICS with rendering) detailing the use, maintenance and repair of ETICS must be considered.

MaintenanceMaintenance of the façade surface should be performed at regular intervals taking the size, architecture and location into consideration. Maintenance is understood to mean cleaning, painting or, if required, renewing of connections on the intact External Thermal Insulation Composite Systems (ETICS). It is necessary to undertake corrective measures as quickly as possible if a maintenance issue is identified in order to assure the ETICS service life and protect the visual appearance. We generally recommend consulting experienced and qualified specialist companies if a maintenance issue is identified.CracksLimited cracking shall not be classified as a fault, if it does not impair the technical and optical characteristic value of the render (compare to DIN 18550-1). In recesses in the render structure, individual fine shrinkage cracks and pores that have occurred in the render and in the coating / paint coats are permissible. A technical defect has occurred if the driving

rain-proofing of the masonry and / or the weathering resistance of the render and coating is no longer assured. A general maximum crack width value cannot be specified, as this is dependent on the render used, the render system and the render substrate in each individual case. A visual defect is present, if the cracks are considered to be bothersome under normal viewing conditions (e.g. perspective, distance), and the rendered surface has a special design or representative significance. Also refer to the WTA Code of Practice "Assessment and Repair of Cracked Rendering on Façades”.Graffiti protection with Sandstein-DesignThe prerequisite for the successful removal of Graffiti is a triple coat of Sandstein-Design sealing. Contamination from graffiti can only be removed using a special cleaning agent. Removal of defilement caused by graffiti can be undertaken by a certified specialist company. After removal, new weather-proof sealing must be applied with Sandstein-Design Versiegelung sealing.

Information on sustainabilityKnauf WARM WALL Basis

Information on the sustainability of Knauf WARM WALL BasisBuilding assessment systems ensure the sustainable quality of buildings and constructional structures by a detailed assessment of ecological, economic, social, functional and technical aspects.In Germany the following certification systems are of particular relevance:

■ DGNB system Deutsches Gütesiegel Nachhaltiges Bauen der DGNB (German association for environmentally sustainable building)

■ BNB (Quality rating system for environmentally sustainable building)

■ LEED (Leadership in Energy and Environmental Design).

Knauf WARM WALL systems can positively influence many of these criteria.DGNB/BNBEcological quality

■ Criterion: Total primary energy requirement Reduction of the building energy requirement over the entire lifecycle due to efficient WARM WALL systems

Economic quality ■ Criterion: Building related life-cycle costs Reduction of the operating costs due to cost-effective WARM WALL systems

Sociocultural and functional quality ■ Criterion: Thermal comfort in summer or winter Cozy room climate with WARM WALL systems

Technical quality ■ Criterion: Premium quality thermal and moisture protection for the building shell With WARM WALL systems significantly exceeding the EnEV requirements
