Preparation first
Before you begin installing the backer board, make sure that the surface where you are going to install it is clean and dirt-free. Remove any loose paint or wallpaper if there is any.
Start the installation processÂ
Start by applying mortar to the surface and spread it evenly. Make sure you apply the thin-set mortar over the entire surface.
Now, gently place the cement backer board over the adhesive and press it down. Make sure it is aligned properly with the stud locations. Leave a small gap between boards to allow space for expansions in the future.Â
Use screws to secure the cement backer board to the wall. The screws should be around 6-8 inch apart at the edges and 10-12 inch apart in the field area.
Corners and joints
To achieve sharper and cleaner cuts, use a jigsaw or a specialised tool to cut cement boards. Make sure that the edges fit seamlessly and do not overlap.
Use alkaline-resistant mesh tape to cover joints and then apply the thin-set mortar over the tape to achieve a finished look.
WaterproofingÂ
If you are installing the cement backer board in your bathroom or any other area that would experience water exposure, add a waterproofing membrane over the cement board to protect it from water damage in the future and improve longevity.
Install the tiles
Now that you have successfully installed the backer board, start installing the tiles by first applying the thin-set mortar over the cement board and then placing the tiles over it.Â
