Hi and thanks for using our service! My name is XXXXX XXXXX I will do whatever I possibly can to give you the most accurate answer.You can scrape the old cement off where the tiles were attached and off the back of the tiles; then clean well with water and let dry. Then purchase a ceramic wall tile adhesive and a 1/8" notched trowel. Apply adhesive to back sides of tiles and press into place, maintaining an equal gap around the tile. Let dry overnight.Purchase a grout that matches the existing; if the joints between tiles are less than 1/8", purchase an unsanded grout. Apply grout into joints surrounding the tiles and let set for 15 minutes; then carefully wipe off excess grout with a damp sponge. Wipe diagonally to avoid scraping out the grout. Wait another 30 minutes and wipe with a dry towel to clean remaining grout residue. Avoid the grout joints at this time; if you accidently hit a joint just massage it smooth with your finger.Let it all dry over night and it will be good to go.
Hi Brian, Have'nt had time to get around to doing the tiles as yet. I Have builders around doing a back decking, & I have just come home from a family drama. I'll be leaving information on my computer as I can refer back to what to do. Thank You.
