Hi folks i wanted to paint my tired looking mdf bath panel so i uase pva first then plasti kote stone touch spray paint then sealed it with pva again (looked great) then when hot water went on it ,it started to lift off can anyone help ?
Why did you use PVA ? PVA should never be used if the surface is to be painted over. Dont believe what they tell you on the tv programs!!! On an MDF bath panel, all it needs is an oil based primer then undercoat then topcoat, rubbed down between coats, and make sure the end grain is well painted or it will soak up water like a sponge !!
If all the wood was painted with PVA then the top coat might just peel off.
Its not so much the topcoat, but the PVA, it causes all sorts of problems after. You could try flatting it off and giving it a coat of undercoat and see then how stable the surface is.
