Can you put thinset over concrete?

Can you lay tile directly on concrete floor?

Do I need to prime concrete floor before tiling?

Primer is absolutely necessary if you have an anhydrite screed (aka calcium sulphate). This is a liquid screed pumped onto the sub-floor that self-levels. It’s quite common in modern construction and has many benefits over sand and cement screeds, but you can’t tile straight onto it with standard adhesives.

How thick can thinset be under tile?

Plan for a layer of thinset 3/16-inch to 1/8-inch thick beneath your tile. A 3/16-inch layer of thinset will be enough for tiles with a smooth back to bond the tile to the floor or backer board. For natural tiles with an uneven surface on the back, you may need to spread a 1/8-inch layer of thinset during installation.

Does mortar stick to concrete?

Mortar will stick to concrete. However, you must prepare the concrete surface first for adhesion to occur by ensuring it is even, free of dirt, and slightly damp. Applying a scratch coat to the concrete surface will help the mortar stick better. For even better results, you can use Thinset mortar.

What is the difference between thinset and mortar?

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 tile adhesive better than thinset?

If installing a small area of ceramic floor or wall tiles, mastic is the better choice. The adhesive is premixed, does not require water and will hold the tiles in place with no beating or additives. If installing a large amount of tiles, stone tiles or glass tiles, thinset mortar should be used.

Do I need primer for thinset?

The primary role of a tile primer is to create better adhesion of a thinset, mud bed or self leveling underlayment (SLU) to the substrate (the surface you’ll be tiling). A latex tile primer can also be mixed in thinset to enhance it’s bond strength, water-resistance and bond-strength.

Do I need underlayment for tile on concrete?

Although you don’t need to install an underlayment between the concrete and the tile, you need to prepare the surface before placing the tile. After all, cracks and uneven areas in the concrete can cause damage to the tile above, and uncontrolled moisture in the concrete can destroy the mortar and loosen the tiles.
