What Preparation Is Needed To Install Porcelain Tile Over Concrete?

More than likely, you are ready to dig in and get started with the installation. Before you do so, however, you want to prepare everything in advance.

1. Clean – The first step in preparing to install porcelain over concrete is to clean everything. Use a broom and dust mop to clean as much of the dust and debris from the concrete floor as you can. You can then mop the floor using either plain water or water with some neutral cleaner and degreaser.

One important factor in cleaning concrete is to ensure that everything is scrubbed properly. You don’t have to worry about being too harsh on concrete and in fact, being a little harsh is a good idea before you install anything over top of it.

You want to do more than simply surface clean the area, you want to ensure that you are getting down into the nooks and crannies and removing some of the smaller issues, including the possibility of mold or mildew.

If possible, you can also clean using a pressure washer, as that will do a great job in removing as much off of the surface as possible. You can also add some degreaser to the pressure washer if desired.

2. Drying – After cleaning the floor you want to ensure that it is as dry as possible. Concrete can soak in some of the moisture, and it may take some time for it to release it.

In addition, if you are dealing with a new concrete slab, then it is important to wait at least 90 days before installing anything over it. Concrete takes a long time to dry when it is first poured and installing too quickly over top of it can cause issues.

3. Patch and Level – If there are any imperfections in the concrete floor, they need to be fixed in advance. Cracks and holes should be filled and patched with some type of patching compound.

This is a step that really can’t be underestimated. If you don’t fix the concrete in advance, any imperfections can transfer to the tile and cause cracking and other problems.

If you have any high spots, which are usually evident as you are cleaning the floor, you should grind them down with a grinder. Low spots can be filled with a self-leveling compound.

One other option is to use the self-leveling compound and completely float the floor. This will give you a clean, flat, and smooth surface to install the porcelain tile.

After patching everything and self-leveling, make sure that you clean the floor once again.

One important factor for installing porcelain over concrete is to put down a membrane material. This can either be a rubber polymer that is painted on the surface or a membrane material that is put on top of the concrete. This helps to protect the tile by keeping small imperfections of the concrete from damaging it.

Once you have the membrane down, take the following steps to install the porcelain tile:

1. Dry Fit – Pull the porcelain tiles from the box and put them down in a row with spacers between them. This will give you an opportunity to see what needs to be cut at the walls and it will also help you to find any imperfections of the tile that need to be addressed at this point.

2. Thinset – Use the mixing paddle and drill to mix the thin-set in a 5-gallon bucket. Use the amount of water that is recommended by the manufacturer. When mixing thin set, make sure you wear a respirator because the dust should not be inhaled.

You will need to wait a few minutes after mixing the thin set before using it. If it sits in the bucket for too long, you will need to remix it for using it again.

3. Apply Thinset – Use the notched trowel to apply the thin-set on the floor. Make a large enough area that you can work with it but it will not dry before you are finished.

4. Put in Tile – Place the title in the mortar and apply pressure. You can also slightly move the tile from side to side so that it gets a good grip.

5. Cut the Tile – After placing the field of full tiles, cut the tiles along the edges and install them. Keep in mind that tile can expand slightly so leave a little gap along the edge of the wall.

6. Grout – Mix the ground and use the grout float to smear it across the tile and into the joints. Remove as much of the grout from the top of the tile as you can with the float.

7. Sponge – Grab a bucket filled with clean water and a grout sponge. Wipe the sponge in a circular motion to clean the top of the tile. Be careful you don’t pull the grout out of the joints. It may take several passes before it is clean.

Concrete makes an excellent subfloor when installing porcelain tile. As long as it is clean, dry, and level, you can install porcelain and know that it is going to be down for a very long time.
