Sikagard®-1315 KNS is an acrylic polymer in a co-solvent emulsion.

15 months when properly stored

Store in unopened containers in a clean, dry area between 40 and 85 °F (4 and 29 °C). Keep from freezing.

Adhesion of tile cement

Acid and Alkali resistance

Times are based upon temperatures of 65 to 85 °F (18 to 29 °C) and 50% relative humidity. Light foot traffic or between coats: 4 hours Normal traffic: overnight Maximum hardness: 7 days Material will take longer to dry at either higher humidity or lower temperatures.

CURING ONLY: 200–400 ft²/gallon (4.9–9.8 m²/L)
SECOND COAT (dust proofing and sealing): 400–600 ft²/gallon (9.8–14.7 m²/L)
RECOATING (dust proofing and sealing): 200–300 ft²/gallon (4.9–7.4 m²/L)
Coverage varies with the application method, texture, and porosity of the surface.

• Sikagard®-1315 KNS may settle and must be stirred thoroughly before and during application.
• For curing only, one coat may be sufficient; 2 coats will give the best results. To seal and dustproof, 2 coats are required.
• Not recommended for use in colored dry-shake applications
• Keep from freezing.
• Do not apply when the concrete surface or ambient temperature is below 40 °F (4 °C).
• Do not apply when the surface temperature is above 120 °F (49 °C). 
• Not recommended as a release agent.
• Do not apply to surfaces of joints to be caulked with sealants. Mask joints to avoid sealant adhesion problems.
• Can be applied to plain and colored concrete, but mottling or discoloration may occur.
• May highlight features and imperfections of the concrete surface.
• Sikagard®-1315 KNS must be fully dry before exposure to water or it may whiten.
• Although Sikagard®-1315 KNS is compatible with a variety of carpet, vinyl tile, and floor-covering adhesives, always conduct a test application before applying.
• Not intended for surfaces to receive concrete overlays or additional toppings, coatings, sealers, or ceramic tile (without proper surface preparation).
• Sikagard®-1315 KNS is considered a light-duty floor sealer; it may rubber burn when subjected to a forklift or other wheeled traffic.
• If Sikagard®-1315 KNS will be applied in or near areas containing foodstuffs, they must be removed before application.
• Extended exposure to moisture may result in a temporary opaque condition that clears upon drying.
• Only mechanical methods of removal are recommended.
• The small amount of solvent vapors released by Sikagard®-1315 KNS may be objectionable to people unaccustomed to the odor; do not apply Sikagard®-1315 KNS in or around buildings occupied by non-construction personnel without consulting building management.
• For professional use only; not for sale to or use by the general public.
• Make certain the most current versions of the product data sheet and SDS are being used.
• Proper application is the responsibility of the user. Field visits by Sika personnel are for the purpose of making technical recommendations only and not for supervising or providing quality control on the jobsite.

1. Freshly placed concrete must be properly finished. The surface is application-ready when it is damp but not wet and when it cannot be marred by foot traffic.
2. Existing concrete surfaces should be thoroughly repaired and cleaned before application. The surface must be clean, dry, and free of dust, oil, grease, sealers, and all other surface contaminants that might inhibit the proper bond of material.

1. Thoroughly mix the material in the original container before applying.
2. Apply a continuous, uniform film by solvent-resistant low-pressure spray only, a short-nap roller, or lamb’s wool applicator.
3. For curing, one coat may be sufficient. However, two coats may be required in hot and windy conditions. Apply evenly and uniformly as soon as possible after final finishing.
4. To seal and dustproof, two coats are required. Apply the second coat when all trades have completed their work and the site is ready for occupancy.
5. Do not over-apply or soak concrete surfaces with the curing compound. Do not allow the curing compound to pool on the surface. Over-application can result in alligatoring and mud cracking, whereby a film forms on the substrate before the material dries properly. Over-application may also cause opacity, as elements of the curing compound become trapped in the subsurface and cannot escape.

Clean tools immediately after use with soap and warm water.
