Hello Swaylockians, I sanded my poly hotcoat a few weeks ago. It has been sitting in my garage for a while and I am worried that the hotcoat is now contaminated. There is definately dust, dirty fingers, and I’m not sure if the Norton 3x sandpaper that i used is stereated or not. I read that some sandpapers are stereated and this can cause adhesion problems in the glosscoat. I want to clean my hotcoat and was thinking of wiping it down with clean paper towels and a little acetone before glossing my board. Does this sound like a good solution to my problem? Any help is appreciated. Much love to the Swaylocks community. Thanks!
Barry, Re-sanding it is a great idea. I am just worried about the sand paper possibly being stearated which I hear can cause problems. Is this something I should worry about? Thanks for the help everyone!
There was a post a little while ago where the epoxy gloss came out nearly perfect. He did it by doing 2 gloss coats. The first was very little resin spread on then removed. The idea was that the first coat trapped all the contaminants and created better adhesion of the second gloss. If somebody can find the threadplease link it up here.
Hang 20 - I doubt I could find the post, but I definitely remember it. A little off topic since the o.p. is working with poly, but I have been using that method, and having good success. I think he called it a cheater coat - mix a very small amount of resin, and squeegee it around, only enough to wet the surface, everything else comes off. Once it starts to gel, mix the regular amount and spread it per normal. Has really improved my results, and I do not work in a clean environment. Epoxy can be finicky.

No. Sounds like a problem on top of a problem. Paper towel = particals. Acetone = health issues. And smeared around gunk. Wash your hands first. Then sand the surfboard. Listen to Barry. Compressed air is good if you are smart enough to have traps and filters. Wash your hands 2 times. Clean shop. No air movement when Hot coating or glossing. Epoxy or poly....there's dirt in my shop. Try to keep it down not up in the air.
Sounds good. Im gonna lightly re-sand the board with 120, do the pinlines, skim it with tape to remove dust, and shoot the gloss. Thanks for the help yall!
I agree. I don’t worry about cleaning sanding dust off before the next coat. but Surfer O, I’m curious about this statement “Im gonna lightly re-sand the board with 120, do the pinlines, skim it with tape to remove dust, and shoot the gloss.” Does this mean you are spraying your gloss coat?
