Once the thinset dries, the tiles may be grouted. Tile installation is simple and can be done by anyone. However, tiles cannot be installed in pools unless the plaster substrate is in good condition.
Contractors will remove the plaster layer from your pool and reveal the pebbles.
Keep in mind, resurfacing a pool is not your average DIY project. Any small mistake can leave you with a leaking pool that can cause damage to your house and backyard.
