Just wondering if you can tile onto bare wood? I have built a vanity unit for my counter top basin, timber frame and plasterboard which will be fully tiled. I have made a recess in the front of the unit roughly the same width as the sink for storage. The unit is entirely plasterboarded with the exception of inside the recess. If I can, I’d like to tile straight onto the timber frame without boarding first but I’m not sure if the adhesive will bond to the wood? I was thinking maybe if I undercoated it first? Any advice would be much appreciated
