| The Corrosion Mechanism
When two dissimilar metals (the copper from the wood preservatives and the zinc from the galvanized metal)
come into contact with one another, in the presence of moisture, an electric circuit is created and corrosion occurs. This same
mechanism makes batteries work. Although CCA also contained copper, its other chemical components (chromate and arsenate) acted
as corrosion inhibitors and slowed down corrosion. Therefore CCA lumber had been successfully used for years.
How Does Grace Vycor Deck Protector Work?
Grace Vycor Deck Protector is the first uniquely formulated solution to help reduce corrosion of galvanized
metal connectors. It is installed between the connector and the pressure-treated lumber and acts as a barrier layer to break the
electric circuit and thus helps reduce corrosion.
Grace Vycor Deck Protector also helps reduce the corrosion rate of galvanized nails that attach the connectors to the lumber by separating
them from the corrosion influence of the large connector (i.e. joist hanger).
Features and Uses
Grace Vycor Deck Protector is a unique solution designed to prevent the problems of joist rot and wood decay.
By wrapping the top of the deck joist it creates an excellent barrier against water and moisture penetration in deck structures. The product's
high performance polyethylene film is backed by an aggessive rubberized asphalt. A slip resistant coating facilitates foot traffic durring
application.
Grace Vycor Deck Protector can be used for all non-roofing flashing applications.
Grace Vycor Deck Protector is a high performance, weather-resistive barrier. It is fast and easy to install, seals around the fasteners and
prevents penetration of water into deck structures.
The 6 in. and 12 in. measurement markings assist the ease of cutting to the desired length.
