Grace Vycor Deck Protector will help significantly extend the useful life of your deck. Preventing joist rot and decay, as a result of water accumulation under the decking boards, remains a problem even with the new high-tech decking systems of today. Moisture control is the first step to rot prevention.

Grace Vycor Deck Protector creates a watertight barrier against water and moisture penetration in deck structures. It's a fast and effective way to significantly extend the life of your decks.

When comparing Vycor Deck Protector to other flashings, Grace Vycor Deck Protector offers walkability grip that increases safety during the installation process. Its skid resistant coating is preferred by builders.
