Consult SDS for details


MaxGuard is formulated as a ready-to-use coating. It can be applied with a brush, roller or airless sprayer to obtain an even finish. Do not apply past the point of run off. A cross-hatching technique is the best way to ensure sufficient wet/dry film thickness and complete coverage. Consult the Enviroguard New Construction Warranty and Enviroguard Existing Construction Warranty documents for details.

Coverage Rate

For warranted best results, apply at 160 ft2 per gallon (800 ft2 per pail = 10 wet mils) based upon location, surface texture, porosity, age and application method. For best results, apply two even coats perpendicularly to each other (i.e. vertically and horizontally). Allow the first coat to dry to the touch before the second application. Does not include loss from over-spray or over-use.
