Important Things to Keep in Mind

Weather Conditions

• Be sure to apply under dry conditions only. Do not apply if rain is expected within 12 hours following application.
• Air and surface temperature should be between 50º and 90ºF for 24 hours following application. This will ensure proper product penetration.

• Do not thin

• If efflorescense is present, use H&C^® Concrete Etching Solution first.
• Before applying your coating, make sure you have followed the proper surface preparation methods for the surface you are coating.
• Two coats are recommended for superior waterproofing, but if seepage still occurs, apply a third coat to seal remaining pinholes.

• Cleanup is easy-simply use soap and water after your project is complete.

Application Methods
First Coat:

• If your surface has corners or edges, coat those with your brush first to assure complete coverage of the waterproofer.
• Using a stiff-bristled nylon or polyester brush, apply your first coat to a clean, bare surface.
• Fill the surface's pores thoroughly and evenly, covering your entire surface.

• Using a brush or a roller, apply your second coating covering the entire surface.
