Do you need to prime concrete before tiling?
Priming New Concrete Floors While adhesive manufacturers say you can tile straight onto new concrete or screed, we would strongly recommend the use of a primer to ensure there is a good “key” for the adhesive to take to. Eventually, this can lead to delamination where the tiles simply peel up!May 26, 2021.

Can you use thinset as grout?
Thinset mortar, commonly used for securing stone to a surface becomes very hard just as a Portland cement grout becomes as it dries. Although the intended use for thinset is not for mortar joints. You can use it on backsplashes and other surfaces that will not see heavy traffic.
What is the difference between cement and tile adhesive?
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. Whereas, MYK LATICRETE Tile Adhesives help you curb wastage on material and resources used to tile the floor & walls and leaves no mess.
How do you seal concrete before tiling?
Pack the sealer into cracks, up to 1/8 inch thick, in the floor and level it with a flat trowel. Spread the sealer the width of one diagonal tile measurement on each side of the crack. Fill the gaps where the floor meets the walls in the same manner, extending the sealer 6 inches on each side.
What kind of Thinset do you use for concrete 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.
Does mortar stick to concrete?
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.
Where and When Should primer be used before any tiling adhesive is applied?
If you are looking to produce quality, long-lasting results, we strongly recommend using a tile adhesive primer prior to laying tiles. A good tiling primer will regulate the adsorption rate of tiled surfaces.
Can I put tile directly on subfloor?

Do I need a vapor barrier under tile flooring?

What kind of subfloor is needed for ceramic tile?
Exterior-Grade Plywood Exterior plywood is an acceptable underlayment for tile and is preferred to interior-grade plywoods because the bonding adhesives used are waterproof. If water seeps through the tile installation to the underlayment, it will not cause the wood to swell, as happens with interior-grade plywood.
How thick does the subfloor need to be for tile?
The subfloor under the tile should be at least 1 1/8″ thick, with a minimum of 5/8″ thick exterior grade plywood topped by 1/2″ cement backer board.
Can you tile over old floor adhesive?
You can tile over your old floor adhesive by placing a barrier down in the form of thin-set, underlayment, a false floor, or using a floor leveling compound before tile installation. To achieve the strongest bond and preserve your moisture barrier, you should scrape, sand, or strip the old adhesive.
