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.
Can I use cement to lay floor tiles?
Generally, I would advise that you should be using a floor tile adhesive instead. Ideally having a thick layer to ensure that the tiles are laid evenly on your floor, if it is noticeably uneven. A cement/sand mixture could be a cheaper solution overall, but if you can afford it the adhesive will likely be better.
What is the best subfloor for a bathroom?
Traditionally, exterior grade plywood has been the subfloor material of choice for many bathroom flooring projects. Plywood is made by gluing alternating layers of wood veneer. CDX plywood (¾”) in particular is used often because it has a high level of resistance to moisture and humidity.
What is better Ditra or cement board?
Ditra is waterproof, while cement board lets water through but won’t be damaged by it. This may make Ditra a better choice if moisture from below is a concern, such as with some outdoor applications or installations over concrete.
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.
When tiling a floor where do you start?
Begin laying tile in the center of the room and work your way out. The first step in laying out tile is to mark a guideline, or layout line, in the room to make sure your tile pattern is evenly centered. Measure the four walls in the room with a tape measure to find the midpoint.

Do you tile from the middle out?
It’s always advisable to start tiling your grid in the centre of the wall, as it’s easier to make sure your pattern is symmetrical. It also means any half-tiles you may need can go at the end of each row and will be of matching size.
Do you have to waterproof a bathroom floor before tiling?
If you have a tiled shower, behind that tile needs to be a waterproof barrier which will contain water that gets behind the tile grout (not waterproof) and direct it to the drain, instead of letting it contact the drywall or subfloor.
How do I seal my bathroom before tiling?
How should a bath or shower be sealed at the wall? When a bath or shower is fitted in a bathroom, the bath or shower unit should be placed against the wall prior to it being tiled and then a silicon seal placed between the unit and the wall. The walls can then be tiled with the tile overlapping the bath or shower unit.

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.
What is primer for tiles?

Do you need underlayment to install 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.
Do I need a vapor barrier under tile flooring?
A moisture barrier helps control the water vapor’s movement to help protect your floors. Therefore, if you’re installing floors in an area that sees moisture, even a little, a vapor barrier is needed.
What needs to go under tile?
What is an Underlayment? 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).
