How to Install Water Line Tile
- 1). Apply silicone-based adhesive to the back of a tile, focusing on the center of the tile.
- 2). Place the tile against the top of the pool wall until it sticks. Only use tiles that are suitable for swimming pools. Paste a length of sticky tape onto the tile and the lip of the swimming pool to secure it in place until the silicone-based adhesive dries. Repeat until you cover the entire water line, and let the adhesive set for 24 hours.
- 3). Use a special applicator to apply silicone grout to the spaces between the tiles. The applicator has a tube at the end that releases the grout in a thin line. Run a finger along the grout lines to smooth out the surface. Repeat until you finish grouting all the tile joints.
