Hey all, I’m hoping I can get some quick advice on this. It looks like there’s no fix for the deck other than sanding it off and re-starting. doing a final coat today over some automotive stick on pin lines, and the resin is seperating away from the lines. It’s also doing the same thing in a couple of other areas, I know that the other areas are where I’d laid some masking tape across the board for guides when I was laying the lines on. I thought I’d cleaned it all up adequately but the resin’s seperating where there must be some small amount of tape residue left.
Any suggestions to help me avoid the same thing happening on the bottom? Do I need to re-clean the board? Do I need to give the pin-lines a light sanding or something?
Oh, it’s RR epoxy. I’ve not used any additive F, as I hear that it goes milky over wood.
Thanks

I always use those pin lines under the laminate. That makes sure I don’t have to mess with it in the gloss (gloss is hard enough without). I’d probably forgo the pinlines or you could shoot them with epoxy resin. But that’s opening another can of worms. Yes ADD F should be minimised when using dark colored wood. Makes things harder to build but the finish is worth the extra work. Light colored wood doesn’t show.
Thanks for the reply Greg, I’ll deffinitely keep that in mind for the next board, it makes sense.
All that I’d read previously pointed to paint/lines and artwork being best done onto the sanded hotcoat, so that’s what I did.
I think I’ve mostly fixed this now by getting another coat of epoxy over the first within a few hours, you can still see the lumps but nowhere near as bad and I’m hoping they’ll sand and polish out OK now.
When doing pinlines with Liquitex acrylic paint it helps to lightly sand the dried paint with 220 grit and lay a thicker hotcoat over it. A thicker hotcoat provides more surface tension to help prevent separation.
But I’ve recently discovered the benefits of pinlining under the lam like Greg mentions above and it’s definitely the way to go in my opinion - No chance of hitting it when sanding the hotcoat and no separation issues.

yep use a water bases artist acrylic and give it alight rub with higher grit paper like 400 or 500 and dont raize the line to high

Cheers for the info lads. Yup, I’ll deffinitely rethink this for next time. It’s been a bit of a pain in the arse but mostly sorted now (hopefully). I do still need to sand and polish, hopefully won’t have any issues. I’ll post a pic or twoo when its done.
thanks again
