I installed three villaboards in my laundry and applied water proofing material over them.. Instead of tiling all the walls up the ceiling, I was thinking of painting the side walls. Can anyone give me any tips on painting over villa boards? Will normal water based paint be ok? Will end product looks similar to gyprock? What about the nails? Bit hard to hide them with plastering.. Part of the villaboard surface is bit rough with the water proofing material.. Appreciate any comment and experience. If its not worth painting, might just have to tile over them.. Thanks..
