Ceramic Tile and Underlay

Ceramic tile material is relatively brittle and rigid, so a sturdy foundation is the most crucial part of installing this kind of tile. Unless you wish to view tiles, free tiles, or loose grout, you should choose the proper underlayment. Underlayment being what the building trade calls the layer which goes between your tiles and your wood sub floor.

You’ve got several alternative approaches to accomplish the strong underlayment necessary for tile installation.


Merely one layer of plywood is not rigid enough to stop flooring deflection. It has to be covered over with the added layer of exterior-grade plywood to accomplish a total depth of at least 1 1/8 inch. Under either of these, a thin-set mortar is used to remove air gaps. Additionally, in toilets, it is recommended to put a “shower pan” over your wood sub-floor.

Cement Backer Board

All these are prefabricated, lightweight concrete sheets used to cover wood sub floors. Fiber glass surfaces both sides and it’s a dense Portland concrete core and has the capacity to withstand prolonged exposure to wetness. Joints of the backer board sheets ought to be staggered such that they do not fall directly over the wood sub-floor joints.

Mortar Mattress

Mud beds, or mortar beds, are used by professional tile contractors largely. They’re composed of a layer of thick roofing felt, then wire mesh, followed with a layer of mortar. The reason it really is used typically by the specialists is that it takes a high level of practice and skill to ensure the mortar bed creates a sufficiently level surface. The other reason is it is the best foundation possible to get a tile flooring. Okay, but why? Because the mortar bed has an integral reinforcement against floor deflections in the kind of the wire net. Translation- less cracked tiles and free grout, and longer -lifestyle flooring.

Concrete Slab

You are able to lay your tile entirely on concrete slab, but if it is right bonded to the concrete, all cracks and holes must be sealed with a concrete crack repair compound which is usually injected under pressure to completely fill and bond cracks so there is no subsequent widening. Some concrete slab has been coated with curing compound to aid the slab set without cracks. This compound must be removed before tile installation to make certain a long-lasting mortar bond, in adhesiveness changes and considering that the compound assists the concrete keep moisture. It’s also significant the slab be as-level as potential, particularly with the bigger tile sizes in use now. Cleaning the concrete entirely of debris and dust will even bring about a greater quality setup.

Over Existing Flooring

One other possibility is laying the tile over existing flooring. There are several things to contemplate. Is the present flooring solid, flat as well as in good shape? Could it be stuck well enough under it to the sub floor to provide assistance? Good. Is the present flooring linoleum or vinyl? Not too great. You have to strip it out or place a subflooring that is good in addition to it. (And watch out for older vinyl flooring, that might contain asbestos fibers. You don’t want to strip this stuff out your-self. Instead, both cover up with a few plywood subfloor or have it is removed by a contractor.) In case you have tile on the floor you’ll be able to put newer tile on top of it as long as it really is surface is not overly smooth and level. You would possibly need certainly to sand the surface to permit your adhesiveness possess a much better chance.

In summary, a little planning and consideration will go an toward the success of your tile installation job as a long-lasting improvement to your property.
