Multi-layer cladding

In case of multi layer cladding, apply layerswith staggered joints according to applicationscheme.Press boards of each layer firmly on to thesubstructure and screw attach each layer separately. For fastening of first layer, spacing of screws can be increased up to max. 500 mmif second layer is applied immediately afterwards(within one working day).In case of multi-layer cladding, a filling of jointsof first layer without further finishing is sufficient.

D131 Knauf Free-spanning CeilingsSpecifications / Substructure

ConstructionKnauf Free-Spanning Ceilings are solely anchored on the walls at perimeter. Knauf Boards are fas-tened to a metal substructure made of Knauf CW profi les as single or double profi les.The application of additional loads like lighting fi x-tures with max. 100 N (10 kg) per double profi le and exposed ceilings such as D127 Knauf Acous-tic Ceilings with load per unit area of 15 kg/m² or max. single load of 100 N with suitable anchors di-rectly to the metal substructure is permissible. Re-

gard extra loads for dimensioning of T or L con-nections.Joints of free-spanning channels are not allowed. Movement joints have to be transferred into the construction of the free-spanning ceilings. Use control joints in the case of ceiling areas over ap-prox. 15 m length, or for narrow ceiling spaces caused by a break of a wall. Separate connec-tions of boards to components made of a dif-ferent building material, especially columns, or

thermally highly stressed built-ins like lighting fi x-tures, for instance with shadow gaps.Knauf profi les are delivered galvanized. The cor-rosion protective coating is suffi cient for indoor application, including bathrooms and kitchens in private housing. For other areas, e.g. under infl u-ence of outdoor air, additional corrosion protec-tion is necessary (see DIN 18168-1 table 2).

D131 Knauf Free-spanning CeilingsApplication / Filling / Coat and Linings

ApplicationSubstructure■ Supporting perimeter connection made of UW

Profi les. Anchoring acc. to table on page 4. ■ In case of sound protection requirements, seal

up carefully with Acoustical Sealant according to DIN 4109, supplement 1, chapter 5.2; porous sealant strips like Sealing Tape are usually not suitable in this case.

■ Ceiling profi les made of Knauf CW Profi les as single or double profi les. In case of fi re protec-tion requirements, apply only double profi les.

■ Connect CW Profi les as double profi les at web with metal screws acc. to page 4.

■ Support length of CW Profi les in UW perimeter runners has to be at least 30 mm. Connect upper fl anges of UW/CW Profi les by riveting, screwing or crimping, if no covering strip is required.

Cladding■ In case of fi re protection requirements, attach

Knauf Board Strips GKF, 25 mm thick, 120 mm wide, as covering strips on upper fl anges of CW double profi les alternating with Drywall Screws TN 3.5 x 35 mm at max. 250 mm centers.

■ Apply Knauf Boards lateral to ceiling profi les.■ Stagger cut edge joints by at least 400 mm while

placing them on profi les. If using 4AK Boards (4-

side tapered edges) cross joints are allowed in connection with fi lling with joint tape, preferably Knauf Joint Tape Kurt.

■ Start fastening of Knauf boards either in the mid-dle or at a corner in order to prevent upsetting deformation. Press boards fi rmly on to the grid and fasten with Drywall Screws acc. to page 2.

■ Use separation strip Trenn-Fix and fi ller or acry-late for connections to other components.

Multi-level CeilingApplication according to instructions on page 16.

FillingSurface quality■ Filling of gypsum boards acc. to the required

quality standard Q1 ro Q4 acc. to Code of Prac-tice No. 2 “Verspachtelung von Gipsplatten, Oberfl ächengüten“ o the IGG.

Filling compoundsSelect suitable fi lling compound considering qual-ity requiremens and board type: ■ Uniflott: Hand filling without joint tape: HRAK, HRK / with joint tape: AK■ Uniflott impregnated: Hand filling of impregnated boards without joint tape: HRAK, HRK hydrophobic, green■ TRIAS: Hand filling without joint tape: HRAK, HRK / with joint tape: AK color adapted to paper color of gypsum boards, reduced absorption for surfaces with uniform ap-

pearance

■ Fugenfüller Leicht: Hand filling with joint tape: HRAK, AK■ Jointfiller Super: Machine filling with joint tape: HRAK, AK■ Readygips: Hand or machine filling with joint tape: AK

Application■ For multi layer cladding, fi ll in joints of fi rst layers,

smooth joints of top layer.■ Fill all visible screw heads as well.■ Recommendation: Fill cut edge joints of visible

layers using Knauf Joint Tape Kurt, no matter which fi lling material is used.

■ Slightly sand visible surface after drying of fi lling compound, if necessary.

General note: Filling of all concealed board lay-ers in case of multi-layer cladding is necessary to preserve the required properties for fi re protection, sound insulation and stability.

Application temperature/ climate■ Filling of joints should only take place after the

boards have been allowed to rest in the given humidity and temperature zones, and no more longitudinal changes can be expected, i.e. ex-pansion or contraction.

■ Joints should be filled at a minimum room and surface temperature of +10 °C (50 °F).

■ In case of mastic asphalt screed, fill joints after screed has been applied.

■ Refer to Code of Practice No. 1 “Baustellen-bedingungen“ of the IGG.

Coats an liningsPre-treatmentBefore applying paints or coats the fi lled surface should be dust-free. Pre-treat and prime gypsum board surfaces before the application of coats and linings (wallpaper) ac-cording to Code of Practice No. 6 of the IGG “Vor-behandlung von Trockenbaufl ächen aus Gipsplat-ten zur weitergehenden Oberfl ächenbeschichtung bzw. –bekleidung“. Ensure that the primer and the coat, paint or lining are compatible.To settle the different suction properties of the fi lled areas and the paper surface, primers such as Knauf Tiefengrund/ Spezialgrund/ Putzgrund are suitable.In case of wallpaper lining a primer that allows an easier removal of wallpaper for redecoration is rec-ommended.

Suitable coats and linings The following coats and linings can be used on Knauf Boards:■ Wallpapers: Paper, textile, and synthetic wallpa-

pers. Use only adhesives made of cellulose ac-cording to Code of Practice no. 16 “Technische Richtlinien für Tapezier- und Klebearbeiten“, re-leased by Bundesausschuss Farbe und Sach-wertschutz.

■ Plasters: Knauf Structured Plasters, Knauf Skim Plasters, entire surface smoothing such as Knauf Readygips or Knauf Multi-Finish, up to 2 mm thickness.

Regard extra load of plaster for the evaluation of permissible room width and when dimensioning L or T connections.

Plaster coating only in connection with filling with joint tape.

■ Coats: Resin dispersion paints, multicolored (rainbow) emulsion, oil paint, matte-fi nish lac-quer, alkyd resin paint, polymer resin paint, PUR lacquer, or epoxy-based lacquer.

■ Silicate-based emulsion paints may be used af-ter application of a primer that is suitable for the respective surface acc. to the instructions of the provider.

Unsuitable are:■ Alkaline coats such as lime, water glass paints

and silicate-based paintsAfter wallpapering or plastering ensure adequate ventilation for fast drying.

Note:Gypsum plasterboard surfaces that have con-stantly been exposed to light without any protec-tion can cause yellowing after coating. Therefore a trial coat is recommended that will extend across several boards including all joints. Yellowing can, however, be successfully avoided only by using a special primer.
