Use and Instructions


All structural surfaces especially in unconditioned and moisture prone areas such as attics, basements and crawl spaces and for post-remediation specifications.


ClearGuard 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.

Your Problems

ClearGuard was designed to solve specific moisture problems.

Structural materials like wood, OSB and concrete are semi-porous to porous in nature. In unconditioned areas like basements, crawlspaces and attics, unsealed surfaces can hold high levels of moisture due to repeated bouts of condensation from mechanicals, improper ventilation, moisture release, and dew point events. In addition, natural disasters can drive large amounts of moisture into and through the building envelope to the point of substantial loss. In either case, elevated structural moisture content can ultimately result in mold growth, structural damage and poor indoor air quality.

Our Solutions

Seals Tenaciously

ClearGuard is a fast drying, self-priming protective coating. It's powerful adhesion comes from the industry's highest rated and tested resin system which "bites and locks" into surfaces for superior, and long-lasting protection.

Double the Product

Other leading coatings typically require 20 wet mils (80 square feet per gallon) to achieve warranted coverage. Due to ClearGuard's proprietary resin and antimicrobial systems, warranted coverage is achieved at only 10 wet mils (160 square feet per gallon). Double the coverage means half the product, in half the time. 

Zero Shine

Preserving the original look of protected surfaces is important. ClearGuard imparts a flat, clear finish so that it looks like there was never a problem.  In real estate transactions, that can make or break a sale.

Uncompromised Moisture Resistance

Due to ClearGuard's superior resin system, it acts as a permanent barrier on surfaces to prevent moisture content increases. This durable acrylic polymer and ceramic technology provides a long service life that is covered by a 10-15 year existing or new construction warranty.

Award Winning Protection

In 1996, our antimicrobial won the 1996 Presidential Green Chemistry Challenge Award for Designing Safer Chemistries. It's leach resistance ensures a long service life. It's non-persistence in the environment prevents pollution and liability.

Uni-Directional Breathability

ClearGuard is breathable to prevent against locking in moisture which could lead to wet or dry rot conditions. This works by allowing water vapor to escape from structural surfaces while preventing absorption from the environment.

Versatility for all projects

ClearGuard can seal new structures, protect existing structures or overcoat existing painted surfaces for additional protection. 

Unmatched Warranty

At nearly half the wet mil thickness of other industry leaders, ClearGuard offers a 10-year limited warranty on existing construction and a 15-year limited warranty on new construction against mold formation on the coating.
