stripping deck paint--painful!

Eric, did you prime before applying deck paint, or just slapped it on after sanding? In thinking just paint a couple coats and be happy with that, but just thot I'd ask to be sure.

I didn't prime it first.

Here it is in action stripping 25 years of Cetol over original varnish for lots of teak on my 22' Marshall Cat, and also did great removing years of Penetrol build-up left from the prior owner's use of that stuff to keep decks looking good,. (It's OK until you stop, and then it is black and peeling.)
So I took home my engine panel (cockpit floor) for refinishing. It looks particularly bad and I want it to be a test run for possible future deck painting.

It's mostly painted non-skid (of unknown type) So first I tried the heat gun and scraper with some success. It was able to cleanly lift off chunks of the non-skid right down to the old gelcoat, although it was slow going and required a lot of heat.

Next I tried Aqua Strip. On the edges which aren't non-skid this worked pretty well, however after two coats (4 hours, 20 hours) it hasn't penetrated the non-skid. And worse, now the nonskid can't be removed by scraping because it doesn't hold together.

As another test I attacked it with the random orbital sander with 80 grit. It resisted this pretty damn well. 10 minutes had produced almost no results, far worse than scraping.

Any suggestions? It appears the non-skid was best removed by the heat gun and scraping. Although I'm still hoping another coat or two of Aqua Strip will get down to the gelcoat.

So far this effort on roughly 4 square feet doesn't bode well for future painting of the entire deck...

I'm finding this to be quite a chore, and I can imagine it's going to get worse once I have to switch over to manual method. The current deck paint, including non-skid areas is a water based acrylic from who-knows-what-store, and that seems to come off with a generous rubbing with acetone. Should I just strip the deck with acetone and then apply the new paint? Or should I carry on with my maddening sanding? Somebody help!
I used a hot air paint stripper on mine then a very light sand and the decks were clear and clean...

Re: stripping deck paint--painful!

80 grit is way too fine for stripping and coarse prep work. Start with 40 and you'll make some headway.

For no gloss finishes like bottom paint, non-skid paint and so forth, I stop at 80 grit on an orbital.
