Water based gloss

[stuartpaul]

I know it's technically not woodworking (well I'm painting wooden doors!) but has anyone any experience of applying water based gloss over old oil based gloss?

I've heard some horror stories and as I have 8 doors plus associated trim and some cladding to do I don't want to waste money on something that might not work.

Is undercoat a necessity or can you get 'one coat' versions? Would the undercoat need to be water based as well?

I really need the quick drying due to dog and children and creeping around for hours while it dries is a nightmare. The other benefit is the lack of fumes and not stinking the house out for days!

Thanks

I did it - once. The new finish didn't 'stick' and went cloudy. That could be down to the original finish, so you might want to try a test area first?

Water based gloss works quite well, the secret is in the preparation. Wash/sand with sugar-soap, green scouring pad and something like 240 wet and dry paper all at the same time so that everywhere is dulled down a bit. Rinse thoroughly. Then you can paint acrylic undercoat and gloss. Not as shiney or brush marks free as oil based.
