To tile over a laminate countertop, create a design plan, measure the countertop, spread adhesive and lay the tile. After allowing the adhesive to dry overnight, grout the tile. This project requires sandpaper, measuring tape, tiles, spacers, thinset, trowel, a tile cutting tool, grout, a grout float and a sponge.
Measure the countertop. Plan how you want to align the tiles, laying them out on the laminate. Find and mark the center of the counter, which is where you need to begin laying the tile.
Prepare the laminate by sanding it. This helps the tiles to adhere to the countertop. Mix and spread thinset, the adhesive, to the laminate surface. Layer it 1/8 of an inch thick.
Starting from the center of the counter that you marked previously, lay the tile, working your way to the outside. Place spacers between the corners of the tile so that the tiles are aligned properly. Cut tiles and fit them on the edges and around the sink and appliances. Make sure the tiles are flat. Allow the thinset to dry overnight.
After the thinset is dry, mix up the grout. Fill in the cracks between the tiles with the grout using a rubber grout float. Use a damp sponge to clean the surface of the tiles of any grout before it dries.
