Hi peeps, I’m sure this question has been asked a thousand times before but I’m still a bit unsure about it. I want to (ceramic) tile above a kitchen worktop where a small section of the wall has been plaster-boarded. Question is, which side of plasterboard is best for tiling onto. The boards I used are grey both sides although one side seems smoother than the other, and I’ve got the smooth side facing out. It’s only a small area so I’m not talking about a whole wall here but it is above a ceramic hob so I don’t want them all crashing down. Cheers in anticipation, Keith
