Stupid Question # 4683 Glass over stained wood

[JBrown]

My question is simple. how well does the epoxy or fiberglass stick to stained wood? I am considering a strip pirough and I would like to do a design at the bow by staining the pieces of the design. I am just not sure if it will cause problems with the fiberglassing.

Thanks

Jim

Use water based stain, NOT oil based.

No sweat. You happened to hit the one thing I know, about which I have some certainty.

Jack, tell me more about your experience

I've used epoxy over oil based stain. It was an oil based penetrating wipe on/wipe off stain not a tinted varnish, the epoxy was west systems.

Haven't had a problem - yet

Off hand I'd expect an organic compound like epoxy would be more miscible in an organic solvent than water, but i'll certainly defer to your experience

 

[Kayak Jack]

My experience was that epoxy didn't stick to oily stuff. You are more skilled than I am, obviously. I'm not sure how you did the sticky stuff.

 

[seedtick]

penetrating oil stain - likely from home depot

put it on, wipe it off, let it dry for a day

come back with epoxy - put it on, let it dry for a day, water wash, sand

come back with varnish - 3 or 4 coats

did your epoxy cure then flake off or just not cure?

you got me worried that i have a PITA job looming over my head

 

[Kayak Jack]

Cured, didn't stick.

Seedtick , you might luck out but a lot of others on here and Matt's web site have tried the oil based stain without happy results. Water based stains , no problem.

The way mine did was to bubble up under the glass when it got really hot.

I think that "oil based" could mean different things in different products these days.

Original meaning was that it was made with linseed or similar vegetable based oils, and some products probably still are.

Linseed soaks into wood and slowly cures. It can take a long time for the oil to completely cure. It isn't "drying" really, it is oxidizing and turning into a solid material, so "curing" is probably the better word. If you epoxy over it while it is still pretty "wet", them maybe that is where the problem lies.

More modern "oil based" finishes might work better simply because they are made out of synthetic resins and solvents that cure faster and more completely? Don't know, cause I haven't tried it.
