Can you install tile directly on 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. Those products should help prevent any cracks in the slab from damaging the newly installed tile.
What goes under tile on concrete?
More than almost any other type of floor covering, tile needs a rock-solid base. If you attach the tile to concrete, you need to take special precautions by uncoupling the tile from the concrete. Rather than using cement boards (CBUs), the favored method is to use an uncoupling membrane.
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.
Do I need a subfloor over concrete?
While a subfloor is not necessary to add structural strength when you’ll be laying finish flooring on top of a concrete slab (as in a basement remodel), subflooring over concrete offers two other advantages: A subfloor will help insulate against a concrete floor that becomes overly cold in winter.
How do I prepare concrete for tile?
Start by sweeping your concrete floor to get rid of all dust and debris. Then clean with a wet mop of plain water. Use a few tablespoons of a degreasing cleaner in warm water and scrub the concrete with a scrub brush. Finally, rinse thoroughly.
Can you lay tile on damp concrete?
There is damp concrete, and then there is concrete that has a water problem. It is never a good idea to install tiles over concrete that is suffering from a water issue. In turn, this will cause the grout joints to allow water to precipitate, or efflorescence along the surface, which is not ideal.
Do you need a moisture barrier under ceramic tile?
Ceramic Tile and Water
But if moisture seeps through the grout in the joints between tiles, it can degrade the thin-set adhesive used to secure the tile and cause the floor to fail. The grout used to fill the joints between tiles is not naturally waterproof, so it needs to be sealed to prevent moisture infiltration.
Does tile need underlayment?
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 do you install porcelain tile on concrete?
- Apply a layer of paint-on, anti-fracture and waterproofing membrane material (liquid rubber polymer that goes on like wet paint and dries into a flexible, rubber coating on the surface) to the top of the concrete.
- Dry-fit the tiles on floor.
- Choose the longest, most visible wall for your area, or the doorway.
Can you put durock over concrete?
James Hardie Industries, makers of HardieBacker®, and USG, makers of Durock®, indicate that their respective cement backer boards should not be installed over concrete. USG: Durock does not expressly exclude concrete, but the material is specified only for minimum 5/8-inch exterior-grade plywood or OSB.
Do you need a vapor barrier under a concrete slab?
Water vapor will always move from a high relative humidity environment below the building into an area of low relative humidity – even through concrete. That’s why nearly every expert in the concrete industry recommends a below–slab vapor barrier to stop the vapor drive of water upward and into your building envelope.
What is the best flooring to put over concrete?
Best Flooring for Concrete Slab Foundation
- Engineered Wood. Natural hardwood flooring offers undeniable beauty and durability.
- Vinyl. As a longstanding choice for kitchens and bathrooms, vinyl has a reputation for extreme water resistance.
Can I put plywood over concrete floor?
If you’re installing plywood over an existing dry concrete floor, you shouldn’t have any problem. However, a new concrete floor contains a lot of moisture. So, you need to allow it to cure for at least 60 days before even bothering to check the moisture level.
