The next step is to apply a concrete sealer on the floor surface.
Diy concrete floor over tile.
Pour concrete sections one at a time that are approximately 1 10 of the total area of the tile you are working with.
If you are doing a thick overlay you need to lay an additional layer to apply over the top of the first layer you just poured.
Use a 3 4 or 1 in.
Before you begin to lay the tile over your concrete slab make sure the concrete is properly prepared.
Start at a broken tile or between tiles where the grout has loosened.
If your old ceramic tile is worn or dated you can lay new tile right over the old and avoid the huge job of tearing out the old tile.
It is helpful to measure and calculate this ahead of time.
It can be physically strenuous and messy but it is a home improvement project that will allow you to cut labor costs by doing it yourself.
Step 4 blend concrete.
Step 1 preparing the concrete.
It will also provide a stronger adhesion between mortar and concrete.
A concrete sealer prevents moisture from staying underneath the ceramic tiles.
Step 3 plan your layout.
Premade tile molds designed for concrete shallow baking pans or even sand may be used to create a form for the tiles.
Making the tiles yourself allows you to customize their sizes and shapes them to the project at hand such as a backsplash flooring for a hallway or a tiled top for a table.
This assumes that the floor underneath is solid concrete and that there are no cracks in the existing tile indicating underlying problems in the concrete.
Work the chisel under the tiles forcing them loose.
This is an optional step but can really benefit your tile installation in the long run.
Laying floor tile over concrete is not a technically demanding job.
Work the chisel between the tiles and the concrete hammering them up with a 2 lb.
