<div>Larry:Jeez, wheredo I start...
I had a Morgan 30 1968, & put treadmaster down in the cockpit. It wasn't real easy to do. It did stay down, i.e.,not peel, but after several years, the edges began to break off. Also, as said, not too kind to the feet. The epoxy (West System) did ooze out and discolor.I knew a British boat, over twenty years old, with treamaster put down by the factory. The owner loved it. He also did a lot of off shore sailing. About every 8 months, (he said) he sprayed it with WD-4; end of maintenance.When I worked off shore on steel decks:
-lots of prep work, four men for several days
-we put down two coats of two part epoxy primer
-one coat of two part (awlgrip type paint), sprinkled, while still wet, a heavy even coat of nonskid.
-immediately followed up with another coat of two part paint. We used rollers to apply paint.
It held up very well for two years (then do it all again). This is in commercial use on a seismic vessel with lots of traffic.
As to the size of grit, we used sandblasting sand. It was much heavier than I would ever want on Livesong.I owned a boat with epoxy encased plywood decks, working alone, it was a lonnnnnnng job to sand off the old deck nonskid. With one part epoxy paint, I did as suggested putting yacht grade nonskid into the paint and brushing on (with almost conitinual stirring). Very hard to keep inside the cut lines, and a hell of a job to get an even spread, much less an even color spread. I put another coat on top to try to even out the coloring. It was white and the non skid would kind of bulk up(?)and the paint would run off the nonskid leaving a different color. Kind of hard to explain what it looks like and why. I gave up on trying to put down cut line with tape, just went on & painted.Now, one of my BIG criteria for a boat is one that does NOT need nonskid replacement....With all this hind sight and advice, is there anyway to rejuvinate Southerly's present nonskid deck?Hope all this has been of some help. If you want more details give me a call.By the way, I have 7 people going sailing tomorrow, 75 degrees, 15 Kts of wind and Rum Drinks!Best of luck , Tom Pinkston
