Sorry if this is a stupid question and been covered before. I tried to search but couldn't find the answer.
I'm ready to start tiling our bathroom but one of the walls has a wooden frame I've put into it to hold up a heavy wall mounted sink and mirror cabinet. Can I tile straight over the wood? I wasn't sure as I know plastering over wood isn't good so not sure about tiling.
Also in terms of prepping this wall, should I fill the cracks around the edges of the frame first and smooth the wall over? If so what would I use?
Thanks in advance for any help, I've never done this before so any advice would be really great.
