Thompson's Water Seal?

[LaurieC]

I picked up some Thompson's Water Seal to waterproof the stand and area around the fish tank, but I just read on the back that it's not to be applied OVER paint or stained wood. I've already painted, ug, so wonder if anyone has ever applied it over paint? Did it work? Did it change the paint color or ruin it somehow?

What did you use to paint the wood? In my experience, it may just not work because it acts as a sealer and sealer has to be applied before the paint/varnish to soak into the wood. If you used wood sealer or stain before you painted your cabinet you're good to go IMO as those peenetrate wood and ensure waterproofing. I have saltwater splashes on my stained and varnished stand all the time with no effect to the wood.

A high gloss Benjamin Moore paint. I think it's too late to apply the water sealer Hopefully the paint will work ok for splashes. If it's getting soaked, I suppose I have bigger problems.

I built a canopy, and I used a sealer before I painted.

TBH, 2-3 coats of latex paint should be fine, as long as it appears glossy and isn't soaking into the wood itself.

You already sealed the wood with the paint. The Thompsons will not work as advertised and will probably just make a mess.

Was it atex or oil based paint? Because latex paints are not that good with water in general.

You're right. Good call.

BTW, they make a hybrid oil-water paint now that is supposed to have the durability and finish characteristics of an oil-based paint, but with less odor and the ease of clean-up of a latex. I haven't used it myself, so I don't know if these claims hold true.

2 coats oil based primer and 2 coats latex which does look glossy, but I'm pretty sure was not oil based. Hopefully ok.

I tried it. Works, but it's more expensive than and good oil based paint and there's no guarantee it will hold as time pass. I would stick to oil primer+ oil based paint if you want solid color or stain+ polyurethane if you want the beauty of wood to be visible
