I used interlux perfection for the deck. For the non skid we primed with epoxy prime-kote and the sanded that with 220. Then used west system foam roller to roll on a mix of perfection color with 50% interlux flattening agent. My friend followed with a large salt shaker putting down the interlux intergrip
Its important to spread the intergrip evenly and to make sure that the paint is also rolled on evenly. The beauty of the foam roller is that only a thin layer is spread on and IMHO you want to put down a thin coat for the intergrip to stick to.
The next day I rolled on another coat with a smaller foam roller - and then another coat the following day. Iam happy with the way it went.
Any questions just ask
