Can you tile straight to concrete?

A: It’s perfectly acceptable to put tile directly on concrete — with a couple of caveats. First, it is important to determine if there is moisture coming up from the slab. You can test for moisture by taping all four sides of 18-by-18-inch polyurethane plastic on the slab.

Can I tile onto concrete floor?

In most cases, it is OK to lay tiles directly onto concrete. But make sure the surface is free of any contaminants, dust, moisture, etc, as these can prevent the adhesive from bonding. If the concrete floor is not in good condition, or may be at risk of cracking, an uncoupling membrane is recommended.

How smooth does concrete need to be for tile?

As noted in the first answer above, the surface to be tiled, in your case the floor, must be flat within 1/8” in 10′ when measured from the high points of the floor. To achieve this, be sure to use the appropriate patch or self-leveling compound (with the same manufacturer’s primer), but never thin set mortar.

What is the difference between mortar and thinset?

In short, the difference between thinset and any other mortar is that thinset does not have lime in it. Instead, thinset has a moisture-retaining agent and generally retains more air pockets than mortar does.

Is there a sealer for concrete?

There are two main types of concrete sealers: film-forming sealers and penetrating sealers. Film-forming sealers include acrylics, epoxies, and urethanes that form a coating on the surface of the concrete. Film-forming sealers, especially acrylics, are more susceptible to wear and will need to be reapplied frequently.

What is concrete etching?

What Is Concrete Etching and Why Should I Do It? Concrete etching is the process of applying an acid and water solution to a concrete floor in order to roughen the surface of the concrete. The acid wash opens pores in the concrete, which ensures strong adhesion of the new coating to its surface.
