Note: Cooler temperatures or higher relative humidity can extend the drying time.

6–10 m²/L (250–400 ft²/US gal.)

Note: Coverage may vary greatly with the porosity of the substrate; extremely porous substrate may require two (2) coats. Perform test panels to ensure desired results and coverage rates.

1. Verify substrate has properly cured. Concrete should obtain 80 % of design strength, typically achieved within 14–28 days.
2. Clean all surfaces of all sand, surface dust and dirt, oil, grease, chemical films and coatings, and other contaminants prior to application. Power wash, sandblast, or shotblast as necessary to achieve the desired surface condition. Repoint any loose, disintegrated, or cracked mortar and allow a minimum of 72 hours of drying time before application.
3. Air, substrate, and material temperatures should be -7 °C (20 °F) and rising at the time of the application. The substrate must be frost-free. Do not apply sealer when temperatures are expected to fall below -7 °C (20 °F) within 12 hours or when rain is expected within 4 hours following application. Maximum application temperature is  35 °C (95 °F). May be applied to slightly damp surfaces.
4. Crack control, caulking, patching, and expansion joint sealants can be installed before or after the application of the sealer. Allow adequate curing time following the sealant manufacturer’s recommendations. Following the application, remove the excess product that might pond on a concave sealant joint.

1. Test a small area of the surface (minimum  1.5 m x 1.5 m  [5 ft x 5 ft]) before general application to ensure desired performance results, aesthetics, and coverage rates and to verify application technique. Allow 5–7 days for the product to fully react before evaluation. Contact Sika Canada Technical Service for details.
2. Stir material thoroughly before and during application.
3. For horizontal surfaces, apply with a flooding action. The sealer may be applied with low-pressure spray, followed by brooming for even distribution.
4. For vertical surfaces, apply by low-pressure, non-atomizing sprayer. Apply from the bottom up for uniform distribution of the sealer. Apply to saturation, with a controlled rundown of 200 mm (8 in). In certain cases, a mist coat before the general application will help break the surface tension and ensure maximum penetration of the saturation coat.

Clean equipment with xylene or SikaSwell®-990. Cured product can only be removed mechanically.
