Instructions: How to Install Hardiebacker Board in Shower Pan

Step 1: Level Out the Flooring

Before installing the backer board in the shower pan, ensure to level and screed (smooth) out any imperfections in the flooring. If there are any large cracks at all, you should fill these in with cement backer board adhesive or equivalent before laying down any boards.

Step 2: Protect the Surround

The area that surrounds where the boards are being laid should be protected by covering it with heavy plastic sheeting. The boards will expand when they get wet, so laying down the backer board could potentially damage any walls or other surfaces around the shower pan if they aren’t properly protected.

Step 3: Apply Adhesive to Backer Board

You can either apply adhesive directly to the back of the backer board or to the shower pan before installing it. If you’re just using standard screws, then applying adhesive to the back of the boards is fine, but if you’re using a thinset option instead, it’s probably best to apply adhesive beforehand.

Step 4: Lay Down Board

Laying down boards is relatively straightforward, but it’s essential to keep the boards as straight as possible and line them up with adjacent boards at all times. If you’re using a thinset, smooth out any ridges that may have appeared when laying down the board before they dry completely.

Step 5: Fill in Cracks

If there are any noticeable cracks or gaps between the backer boards, then you’ll need to fill these in before installing the shower pan. Shower pans are thin layers of waterproof material that sit below your feet while taking a shower or bath.

Water can easily pass through them when they have wide cracks, so filling these in is important to the overall waterproofing of the shower pan. This is where the thinset comes in and any other cement backer board adhesive you may choose to use.

Step 6: Wait for Cement Board Adhesive to Dry

Letting a cement backer board dry can take anywhere from 4 hours to a few days, depending on what product you’ve chosen to use and how thick and large the area you’re working on is.

After about 10 minutes of drying time, you should be able to turn the backer boards over without causing too many problems. The adhesive will bond them into place and keep them there until it’s fully dried.

Step 7: Lay Down Shower Pan

Once the cement board adhesive has dried, you can go ahead and lay down your shower pan. The best option for this is to use a premixed mortar that matches the color of whatever material you choose for your tiles or panels. Before laying down the tile backer boards, smooth out any ridges using a trowel.

Step 8: Apply Cement Board Adhesive to Tile Backer

Once your shower pan is in place, you need to apply the cement backer board adhesive or thinset to the back of your tile boards before laying them down. Applying adhesive beforehand is probably unnecessary if you’re just using screws for this step.

Step 9: Lay Down Tile Boards

Once the cement backer board adhesive or thinset is applied, you’ll need to lay down your tile boards before it dries. This way, they will remain firmly in place while the adhesive cures.

If you want to be extra cautious about ensuring they stay put, then you can drill holes through the tile backer boards before laying them down to help secure them in place.

Step 10: Trim Tile Boards

If necessary, you can use a tile saw to cut the edges of your boards to fit around any obstacles that may exist in your shower pan, such as faucet holes or uneven tiles. If this proves difficult, then using an oscillating tool with a fine blade to score the board and snapping it in place will work just as well.

Step 11: Finish Tile Installation

Once your boards are set, you can go ahead and apply grout if necessary over top of them before they cure completely. The type of grout you choose is entirely up to you, but most types of tile backer boards will work with any type of grout.

Just make sure you follow the instructions on your chosen grout package closely to ensure that it cures properly.
