Metal wall tile is a beautiful and modern choice for installing over your concrete wall. There are a few things you will need to consider when doing your installation. Following these instructions you will find your end results to be beautiful.
Level of Difficulty:
Step 1: Prepare the Concrete
Ensure that the concrete is properly prepared before you lay the tile over your concrete. Use a scrub brush and clean the concrete with a soapy solution and rinse thoroughly using the sponge. Allow it to dry. Examine the concrete and repair any imperfections. Any uneven areas will make the tile lie unevenly and buckle. After any repairs have dried, take the time to seal the concrete. This will keep moisture from getting under your tiles and settling. This will also allow your adhesive to stick tightly and correctly.
Step 2: Prepare for Tile Installation
Measure the area you wish to install the wall tile and plot it on graph paper. Plan your starting spot to make sure that you can hide the cut pieces as much as possible. It is always best to mark your starting point and then snap a chalk line the whole length of the surface. You can use this line to assure that your row is square and even.
Step 3: Install the Tile
You can lay out the tiles on the floor to see how you wish to install them on the wall. In this way you can cut pieces in the layout to help to hide them or make the edge pieces to maintain symmetry in your design. Find the center of the concrete and make an X with the chalkline to indicate true center. Put adhesive in the center of the concrete and working from the center out take the tiles laid out on the floor and adhere them to the adhesive. You will have to hold each tile in place until the adhesive holds it in place.
Step 4: Finish Installation
When you get to the outside edges of where you are putting your metal tile design be sure that your cut pieces have a clean edge. After all your tiles have been set and you are confident that they will stay where they were installed then you can use a metal tile border to create a clean and finished look to your install. These borders can either be adhered to the surface using a clear silicone or small concrete tacks. If you use tacks you need to drill small holes in the concrete for the tacks to go through and anchor to the wall.
Step 7: Clean Up
When you are sure that the adhesive is dry, usually in 24 hours, use the sponge and a plastic scraper and remove any excess adhesive that may have oozed through the tiles or around the perimeter. You can even use a metal and concrete sealer on the surface to reduce the potential for moisture to get behind the metal and spoil the concrete and to protect the metal surface from any environmental problems like discoloration.
