How To Apply Ceramic Tiles To Concrete

Installing ceramic tiles over concrete can help to create a more inviting indoor or outdoor living space.

What You’ll Need:1. Cleaner: A muriatic or other acid-based cleaner is usually the best way to

completely clean the concrete prior to installing tile.2. Concrete Patch/Floor Leveler: The floor must be level or your tiles and

grout will form cracks.3. Concrete Sealer: This should be done before adding a floor leveling

compound. A sodium silicate or lithium silicate based sealer will help to waterproof and strengthen the concrete. Because silicates work below the surface, they won’t interfere with adhesion.

4. Tile: Choose the type and style you want to go with. Make sure you add 15% to your square footage measurements when ordering to compensate for mistakes and for cut pieces.

5. Mortar: Different kinds of tile require different types of mortar. Ask the sales representative who sells you the tile to help you choose the right one.

Continued:6. Trowel: A grooved trowel will be necessary to spread the mortar. They are

available with different sized grooves, so be sure to read the package directions on the mortar to ensure that you buy the right size.

7. Grout: Aside from being available in many different colors, grout comes in two varieties: sanded and un-sanded. The sanded variety is used when the gaps between your tiles is bigger than 1/8″. The sand gives the grout additional strength. Anything 1/8″ or smaller will be just fine using un-sanded grout. You will most likely find that you want to use the un-sanded grout in the smaller gaps because it finishes much smoother. Working sanded grout into a small gap can be frustrating. One word of warning: if you are using marble tile on your floor, never use sanded grout! Make sure you install it with 1/8″ or smaller gap because you must use un-sanded grout with marble. The sanded grout will scratch the surface of the marble tile and it is not repairable.

8. Grout Float: This is used to work the grout into the gaps between the tiles.

Prepare The Concrete:

The Armor Concrete Cleaner & Micro Etcher deep cleans the concrete and opens up surface pores to allow for adequate adhesion for concrete coatings, and better acid staining color development and reaction.

Using an acid based cleaner or deep cleaner such as The Armor Concrete Cleaner, clean the concrete and allow it to dry thoroughly. Examine the floor and see if there are any cracks or pits that need to be fixed and use the proper concrete repair kit to repair them.

Once your repairs have dried, take the time to seal the concrete with a penetrating sealer.

Used to Waterproof Your Entire Basement (Walls and Floor) – The Armor S2000 is a highly concentrated, enhanced silicate-based sealer, which penetrates deeper, carries more active minerals, and seals tighter than any other concrete sealer on the market. While it is designed to be applied from the inside of the basement, it can be applied to the outside of the foundation as well.

Once the sealer has dried, apply the concrete patch or leveler and make sure that you have a flat surface with no defects.

Plan The Layout:

Before installing the tile it is a good idea to lay our your design. Pre-plan which and how many pieces of tile have to be cut and where the cut tile will be placed. Chalk lines will become very helpful so make sure you mark the floor.

Mix The Mortar:

After you have decided where you want to begin, follow the instructions provided by the manufacturer and begin to mix the mortar. Don’t mix too much in advance as it will begin to set up on you before you can use it. Using your grooved trowel, begin spreading the mortar over a small area. Never spread out more than what you can cover with three or four tiles at a time.

Install The Tiles:Lay the tiles into the mortar and using the spacers, make sure you are running even with the chalk line. As you move on to the subsequent rows, use the spacers to keep your pattern square. Once a tile is set, try to avoid touching it again.

Wash the tiles off with a damp rag as you go to prevent clumps of mortar from drying on the surface. As you get to the end of the room, make sure your cut pieces fit properly, and then leave the mortar to dry for the manufacturer’s specified length of time.

Apply Grout:

Mix the grout as specified on the package and begin liberally spreading it over the tile using the grout float. Use the float to make sure that there are no low spots, and then use a damp rag to wipe any excess grout from the face of the tile. Don’t worry at this point if the tile appears a little cloudy. Once the grout has had time to set up, repeat the process, again using the float to squeegee and extra grout off of the face of the tile.

Clean Up:

• Once the grout is completely dry, take a wet rag and wash the surface of the entire floor. As the floor dries, you will probably notice a haze forming over the tile. Allow it to dry completely again, and then go back over it with a slightly damp rag – this should polish the haze right off.

Once you have polished the remaining grout and mortar residue off of the floor and you are confident that the grout has fully cured, use the grout sealer to prevent stains and mildew from taking hold in the future.
