Prep Work: The cost of prep work depends upon the condition of your pool. If prep work is not done properly, you may run into problems later on.
Retiling, another option, can bring your pool back. The process is exactly the same as indoors. A scratchcoat is applied, tiles get laid, and grout is then added. Tiling can take a lot of time and money depending on the size your pool. But you will get an elegant result.
When laying new tiles, a thin-set is used. It bonds the tile to suitable substrates. Thin-set will not adhere to painted surfaces or other non-porous surfaces.
