Hello Pool Guy! I have watched some of your videos and my question is I have a Pool slide that was done or finished in Small 1inch penny tiles. It was built about 5.5 years ago and now the grout lines are beginning to crack or get really thin and some tiles here and there are popping out. Is it possible to remove all that tile and refinish the slide just with a smooth concrete finish and stain it like stain concrete? What is avg cost for this? Could you just put concrete on top of the tile even?
