Paint compatability

[patrickbwells]

I have been sanding, scraping, sanding, fairing, sanding, fiberglassing, and sanding my decks in preparation for a new paint job. I had already bought Interlux Primekote without realizing that it could not be applied over one part paints. There is still some nonskid and primer on about 25 percent of the decks and I really don't think that I'll be able to sand all of it off. Is there a test or something I can do to find out if it is a one or two part paint on the deck? Maybe I could prime over it anyways, the little remaining paint is in the grooves of the nonskid so there is plenty of gelcoat for the primer to adhere to. Any advice would be helpful, thanks.

Have you considered soda blasting the non-skid? I cleaned my non-skid out quite efficiently by blasting. A 50 dollar unit at Northern Tools and a compressor was my investment. Having a blaster for parts has also been handy.

I am planning on using that kiwi product on the non skid areas of my deck. I see by the posted pictures it will cover some sins, but not all.

I should have posted this with my message.

Do you have a link to which unit you bought... I'd be interested in seeing it.

I bought it at the local Northern Tool about 5 years ago. I'll search for a link.

It's black and made out of the same plastic as a gas can. It's about two and a half feet tall with a big fill hole in the top and very safe and easy to drag around the deck. it has a hose with the nozzle coming out the bottom. You can buy all sorts of media for it for all sorts of applications. Soda was recommended buy a local boat yard for environmental reasons. Not sure why. A very fine glass bead can be a little pricey but you can get play ground sand for a few bucks a bag . . . but sift it if you do. You have to be careful though. Use the smaller tip or you could blast through the gelcoat.

With a quick glance I couldn't find mine on their site but I'm sure they still carry it.

Patrick,
Try the solvent for the new paint on the old paint. Let it sit on it for twenty minutes or so. You might even rub it with a rag at the end of the application time. If the solvent lifts the old paint your new paint will not be compatible with the old as it will lift it, making all of your efforts in vain.
