Does Vycor Deck Protector protect the fastener inside the wood from corrosion?
The use of Grace Vycor Deck Protector can help reduce the corrosion of the nails at the wood interface (the most corrosion susceptible area of the fastener), by separating it from the galvanic effect of the large connector (i.e. joist hanger). Grace Vycor Deck Protector could also help drive down the corrosion rate of the nails inside the wood. Use hot-dip galvanized (HDG) fasteners per ASTM A153 when attaching galvanized metal connectors.
