How to install ceramic tile in basement floor

Acrylic sealer — This easy-to-apply sealer is best for basements and other concrete floors that will not come into contact with oil or grease.

Acrylic sealer sits on top of the concrete instead of seeping in, which makes it ideal for sealing interior floors. Modified thinset is the product of choice for most tile installations because of its increased strength and bonding with minimal shrinkage, which means a reduced chance of cracks forming in the tile.

WarmlyYours Radiant Heating recommends modified thinset mortar for nearly all tile and stone installations. Tile may be strong, but it needs a solid, supportive base. An underlayment is the solid stabilizing layer directly below the tile and the tile adhesive usually a thinset mortar. Using the wrong one can spell disaster for your tile installation. These poor tiles were installed improperly; they never stood a chance.

If tile is laid directly on top of concrete, this expansion and contraction will cause stresses that fracture or delaminate the tile. Other less common and more challenging substrates like asphalt and metal require an uncoupling membrane to ensure the tile will adhere to these surfaces. Concrete slab was the foundation, original tile installation had mortar applied directly to concrete slab. Concrete, mortar or similar materials are not designed to stick or bond to old surfaces.

You will not get any satisfactory results if you simply add new mortar to old. As a general rule, we would say use a primer of some description to prepare your floor prior to tiling.

For instance, an old concrete floor that was tiled previously will probably not need a primer, as long as the surface is clean and free from old adhesive and anything else that was stuck to the floor.

Concrete provides one of the most stable working platforms in the world and is the preferred foundation layer for a ceramic or porcelain tile installation. Cement is a cheaper material when compared to Tile Adhesives. You are likely to spend more on skilled mason and material while tiling with cement. Underlayment is something you put on top of your substrate to prepare it for tiling. Cement board or backer board are the most standard underlayments. Tile can be laid on plywood.

But do not install tile directly on the plywood subfloor itself. Use an intervening layer of a sheet of thinner plywood. Mostly concrete subfloors transmit moisture. However, if you choose to remodel your basement and need a new floor, the first thing to consider is what type of floor you need. Several varieties of tiles, including ceramic and vinyl, can be used; choose the one that best suits your anticipated use. Clean the concrete surface. This is a vital step of the project. Accumulated mud, dirt and other debris must be removed completely to ensure that the tiles are laid properly and stick to the concrete.

For this purpose, be sure to use a commercial or industrial strength cleaning agent, along with lots of water and a brush. Perform the concrete repairs and leveling. To lay an even surface, the underlying concrete needs to be uniform and level as well. To achieve this, get rid of any protrusions, bumps or cracks in the surface. Using sandpaper to level the bumps and concrete and other fillers to stop cracks, you should be able to get a smooth surface. Be sure to wash it after this is done and let it dry.

Plan the layout. After preparing the surface, plan how you intend to lay down the tiles. Depending on size and shape, you can have a wide variety of patterns to choose from and you may even decide to get creative with your patterns and create something original. Be sure to plan this out carefully before starting the actual work to ensure that there are no mistakes. Lay the tiles. Once everything is ready, start by applying a layer of mortar to the floor. Mortar is basically the adhesive that helps the tile stick to the concrete, so choose the one that best suits your needs and your current situation.

The commercially available mortars generally need to be mixed with a proportional amount of water. Be sure to read the manufacturers instructions on this. Once you have prepared your mortar solution, use a trowel to spread it onto the floor. Once the mortar has been spread evenly, gently lay the tiles and tap them into place with the trowel.

Complete the finishing touches. Once the tiles have set properly, finish them off using grout. Grout is commercially available in a variety of colours, choose the one that suits your needs best.

Mix as directed and apply to the gaps in the tiles. Be sure to clean off the excess grout from between the tiles and any that spills onto their surface. After this is done, let the floor set for a couple of days. Clean off the floor one last time with a wet mop, and then it is ready for use.
