StoGuard waterproofair barrier membrane(Note 3)

1] Prepare substrate by:• striking mortar joints flush• removing mortar

droppings or otherdebris from surface

• cleaning any dirt,efflorescence or otherbond-inhibiting materials

• repairing any cracks ordamage to the wallsurface.

2] Repair minor, up to 1/8-inch (3mm) nonstructuralcracks with Sto Gold Fill®and StoGuard Mesh, orStoGuard RapidSeal™.Allow crack repair to drybefore applying StoGuardwaterproof air barrier.

C) StoGuard® VaporSeal™(low perm)

4] Apply Sto Gold Coat® orSto EmeraldCoat® in twocoats, minimum 30 wet milsper coat. All applicationsmust be applied such that avoid and pinhole freesurface is achieved. ApplyStoGuard VaporSeal minimum 40 wet mils in one ortwo coats depending onapplication method andconditions.

5] Refer to Sto specificationsand product bulletins fordetailed information onsubstrates and Sto materialoptions.

IMPORTANT: The number of coats and thickness of coating is highly dependent on CMU composition, unit weight (lightweightor normal weight), porosity, joint profile, and other variables that may exist. For irregular or “rough” CMU wall surfaces skimcoat the entire wall surface with a Sto base coat, leveling or parging material to fill and level the surface prior to applying thewaterproof air barrier membrane and transition materials. When a skim coat of the leveling material is to be applied only onecoat of the waterproof air barrier membrane is typically required (refer to Sto Detail 21.00b). Use a site mock-up and site testsas the basis for the work.

IMPORTANT: The number of coats and thickness of coating is highly dependent on CMU composition, unit weight (lightweightor normal weight), porosity, joint profile, and other variables that may exist. For irregular or “rough” CMU wall surfaces skimcoat the entire wall surface with a Sto base coat, leveling or parging material to fill and level the surface prior to applying thewaterproof air barrier membrane and transition materials. When a skim coat of the leveling material is to be applied only onecoat of the waterproof air barrier membrane is typically required (refer to Sto Detail 21.00b). Use a site mock-up and site testsas the basis for the work.

1] Prepare substrate inaccordance with StoDetail 21.00a, 21.00b or21.00c.

2] Refer to Sto Details21.00a, 21.00b and21.00c for StoGuardwaterproof air barriermembrane productoptions.All applicationsmust be applied suchthat a void and pinholefree surface is achieved.

3] Incorporate flashing asillustrated in Sto Detail21.23 or per otherdetails where flashing isshown.

4] The complete installa-tion of the window ormechanical equipmentmust include an air sealbetween the object andthe StoGuard protection,inbound of the outerperimeter weather seal.

Cladding omitted forillustration purposes.Install cap flashing inaccordance with appli-cable designdocuments

IMPORTANT: The number of coats and thickness of coating is highly dependent on CMU composition, unit weight (lightweightor normal weight), porosity, joint profile, and other variables that may exist. For irregular or “rough” CMU wall surfaces skimcoat the entire wall surface with a Sto base coat, leveling or parging material to fill and level the surface prior to applying thewaterproof air barrier membrane and transition materials. When a skim coat of the leveling material is to be applied only onecoat of the waterproof air barrier membrane is typically required (refer to Sto Detail 21.00b). Use a site mock-up and site testsas the basis for the work.

1] Prepare substrate inaccordance with StoDetail 21.00a, 21.00b or21.00c.

2] Refer to Sto Details21.00a, 21.00b or21.00c for StoGuardwaterproof air barriermembrane productoptions.All applicationsmust be applied suchthat a void and pinholefree surface is achieved.

3] StoGuard TransitionMembrane options:A) StoGuard RapidSealB) Sto Gold Fill andStoGuard Mesh (topcoated with StoGuardwaterproof air barriermembrane)C) StoGuard Fabric withStoGuard waterproof airbarrier membraneD) StoGuard Tape

4]Refer to Sto specifica-tions and product bul-letins for detailed infor-mation on substratesand Sto material options.

5] Verify continuity of airbarrier assembly whenintegrating StoGuardsystem with roofing sys-tem.
