Introduction
If you’re planning to install tiles or other finishes in high-moisture areas like bathrooms or kitchens, it’s important to use a cement board like USG Durock. Cement boards provide a strong, durable base for tile and other finishes that can withstand moisture and humidity. Here’s a step-by-step guide to installing USG Durock cement board.
Materials Needed
Before you begin, make sure you have all the necessary materials. You’ll need USG Durock cement board, screws, a drill, a circular saw, a utility knife, a straightedge, and a trowel.
Preparation
First, prepare the surface where you’ll be installing the cement board. Make sure it’s clean and free of any debris or loose materials. If you’re installing the cement board over wood framing, make sure the framing is solid and level. If it’s not, you may need to add additional framing or shims to create a level surface.
Cutting the Cement Board
Measure the area where you’ll be installing the cement board and use a straightedge and utility knife to score the board. Then, use a circular saw to cut the board to the correct size. Be sure to wear eye and ear protection when using a saw.
Installing the Cement Board
Once you’ve cut the cement board to size, you’re ready to install it. Use a trowel to apply a thin layer of thinset mortar to the surface where the cement board will be installed. Then, place the cement board onto the mortar and secure it with screws.
Finishing the Seams
After you’ve installed the cement board, you’ll need to finish the seams. Use a joint tape to cover the seams and then apply a thin layer of thinset mortar over the tape. Smooth out the mortar with a trowel to create a seamless surface.
Allowing the Mortar to Dry
Once you’ve finished installing the cement board and covering the seams, you’ll need to allow the mortar to dry completely. This usually takes at least 24 hours, but it’s important to check the manufacturer’s instructions for specific drying times.
Tile Installation
After the mortar has dried, you’re ready to install your tile or other finish. Use a notched trowel to apply a layer of thinset mortar to the surface of the cement board and then place your tiles onto the mortar. Be sure to use spacers to create even gaps between the tiles.
Grouting
After you’ve installed your tiles, you’ll need to grout the gaps between them. Mix your grout according to the manufacturer’s instructions and then use a grout float to apply the grout to the gaps. Be sure to wipe away any excess grout with a damp sponge.
Clean-Up
After the grout has dried, you’ll need to clean up any remaining debris or dust. Use a damp sponge to clean the tiles and remove any grout haze.
Conclusion
Installing USG Durock cement board is an important step in creating a durable and long-lasting tile installation. By following these steps, you’ll be able to install your cement board with ease and create a strong base for your tile or other finishes.
