HI all I am considering doing my deck. Painted my mast and boom with a brush and Alwgrip last year and was very happy with the results.
I have an S2 and as anyone who has sailed on one knows they have a very aggressive diamond cut nonskid. What do you do with that. I know you could just grind it off but since it is really too sharp as it is what about cleaning it, priming it and then top coating it ?
I painted right over my non skid. The pattern wasn't as aggressive as an S2, but I think you can get good results. I sprayed my deck with Interlux Perfection, and the non skid areas got Intergrip added to the paint. I was very surprised and pleased with the way the intergrip sprayed out of the gun and with the way it stayed suspended in the paint (unlike sand based products).
Buy the best respirator money can buy. Epoxy paint is deadly toxic when sprayed. 202 hurts your lungs and is likely toxic as well. I bought 2 HVLP spray guns at Cummins Tools (similar to harbor freight) and threw them away when I finished with them. You can use lacquer thinner to clean them, but they're cheap guns.
The first step is cleaning. That sucked bad. You have to use Interlux 202 solvent and BRONZE wool. Pour on a little 202 then scrub like hell with the bronze wool, then wipe it off with a paper towel. You'll be amazed at how much crap will come off. Once you've scrubbed every inch of the deck, start over and do it again. Now carefully mask everything you don't want painted all the way to the waterline. I can't stress enough the importance of using good tape. Buy your tape at an automotive paint store, it's twice the money but worth every penny. Touch up any places that you got dirty. I bought a box of shoe covers at a medical supply store. I slipped them on as I was on the ladder before stepping on the boat. They saved me a bunch of problems.
I primed the deck, then waited overnight and primed it again. I didn't do any prep work in between. I used flattening agent on my deck because I didn't want the sun reflecting into my eyes. It's also easier to hide mistakes. A 50/50 mix of paint and flattening agent gave me a nice finish somewhere between a satin and semi-gloss. A pearly glow is a better description. I sprayed white paint on all areas that didn't have non skid on them. No need to tape off the non skid for this, just let it overlap. Then another coat of white. Now the real fun part. Taping off the non skid. I used 1/8 inch striping tape (blue plastic tape) around the edges of the non skid, then taped and masked off from there. That took about 10 hours, maybe a little more. Then I sprayed the non skid areas with Oyster color paint with flattening agent and a lot of Intergrip.
The result was a very grippy deck that looks great. You can still see a little bit of the non skid pattern, but it looks great.
