Question: Can You Use Backer Board In A Shower

In showers, the standard substrate is tile backer, also called cement board or cement backer board. In addition, because showers and bathtubs are wet areas, they need a substrate that will not be damaged by moisture, just in case a crack in the tile or grout lets water through to the backer.

What is the best backer board to use in a shower?

Cement board is a good, reliable backer board that works well on both floors and walls. Keep in mind that most tile setters err on the side of caution and brush a waterproofing membrane on top of cement board when it is in wet areas like showers or tub surrounds.

Can Hardie backer board be used in a shower?

Installing cement backerboard is one of the more popular choices for a shower wall substrate. Cement backerboards include Hardiebacker, Durock, Fiberboard, wonderboard, and similar products. When installed properly they will give you many, many years of durable shower construction.

How do you attach tile to wood?

Glue, called mastic, is the least expensive method for installing tiles. Mastic adheres the tile directly to a wooden sub-floor, to a wooden back-splash or onto a piece of plywood.

Which is better durock or Hardibacker?

Durock is a reliable cement product that contains glass mesh. It is the heavier of the two materials, which means it is more difficult to use and maneuver. HardieBacker is much more light, and it is also the best selling brand of cement board available. It is much cleaner because it does not have any glass in it.

How soon can you tile over HardiBacker board?

Let the mortar fully set and dry for 24 to 48 hours before tiling. Here are a few things to keep in mind when learning how to install cement board.

Do you install backer board before shower pan?

It requires no mud job or waterproofing membrane, but it does require direct access to the studs of the shower. This will create a small lip at the bottom of the shower walls where tiles or an acrylic surround would bump out, leaving a gap. Therefore, the pan must be installed first.

Does Hardibacker need a vapor barrier?

Hardibacker doesn’t need a vapor barrier or waterproofing except you do need to tape and thinset the joints.

Does cement board need to be waterproofed?

So, if you’re looking for durability and strength, concrete backer-board will probably be your choice. First, you should provide a waterproof/resistant membrane against the wood studs before installing the concrete backer-board to protect the wood studs from moisture absorbed through the backer-board.

How do you put tile on a HardiBacker board?

How to Lay Tile on Hardibacker Board

  1. Set a sheet of HardiBacker board in one corner of the room.
  2. Screw the board down with galvanized screws (1 1/2 inch) into the board’s surface, sinking a screw at each of the dots that are visible across the board’s surface.
  3. Press fiberglass drywall tape over the lengths of the seams between the boards.

Do you need to prime plywood before tiling?

If tiling on fibre-reinforced cement sheets, or plywood/chipboard, then we would always recommend priming the reverse side and edges with BAL Bond SBR. This helps protect the plywood from moisture penetration which could cause the board to swell.

Does shower wall tile need backer board?

You don’t need to use a backer board in the entire bathroom, just in the wet shower area. Choose a backer board that’s the same thickness as the drywall so you have a seamless transition from one to the other.

Do you put Thinset under Hardibacker?

The installation manual for HardieBacker suggests to embed it in thin-set and it should be installed over plywood. Thus I would suggest removing the current wood planks flooring, install a 3/4″ outdoor grade plywood, thinset and then your HardieBacker (screwed down). You do not need to tape or thinset.

Can you tile straight onto HardiBacker?

The Hardibacker will be fine to tile straight onto.

Do I need a vapor barrier behind cement board in shower?

You still need a vapor barrier with cement board, although in this case the barrier can go behind the board. Cement board is heavy enough and breathable enough to take the moisture without a problem. By having the vapor barrier behind the cement board you stop the moisture going further into the wall.

How thick should cement board be for shower walls?

The minimum recommended thickness for the shower wall is 1/2″ because like some of the other boards, they become far too flexible at thicknesses below 1/2″. Foam shower tile backer boards are generally about 4x the cost of cement board.

Can you use cement board in a shower?

But when it comes to getting wet these fiber cement tile backer boards hold up well. They will soak up water but will dry out without losing their form. Because they will absorb moisture there should always be some sort of a moisture barrier when using these tile backer boards in a shower or other wet area.

Do I need to waterproof shower walls before tiling?

Contrary to popular belief, ceramic tile and grout, by themselves are not waterproof. Water can penetrate through cement-based grout and work its way through the substrate. To prevent water damage, you must install a waterproof membrane just below the tile bonding mortar as close to the tile as possible.

Does Hardibacker need to be waterproofed?

Contrary to popular thought, tile and grout are not waterproof, and some moisture will penetrate even if sealant is used. If you decide to go this route, no sealant will need to be applied on top of the backerboard, as this could trap moisture between the two layers of waterproofing.

Do you use backer board for wall tile?

Applications. Use backer board for all your tile jobs, including floors, walls and counters. You can also use it for thin exterior brick and stone. Some companies manufacture backer-board sheets with a rougher side for use with thinset mortar and a smoother side for use with ceramic-tile mastic.

Can I tile directly on plywood?

While tile can be laid on plywood, do not install tile directly onto the plywood subfloor itself. Use intervening layers of two sheets of plywood.
