We did our decks with Interux Perfection (2-part polyurethane) with Interlux's Intergrip additive. The additive is made of small beads - the anti-slip component. The key to a good result is constant gentle stirring of the mixture to insure that the beads are suspended throughout the
paint. The beads can be added to any
deck paint but we preferred the looks and hardness of
Interlux Perfection.
