How To Put Backer Board In A Shower

Whether you're remodeling an existing shower or building a new one, properly installing the backer board is crucial for ensuring a waterproof and long-lasting shower system. Backer board provides a solid and stable base for attaching shower tiles, making it an essential component of any shower installation. In this comprehensive guide, we'll walk you through the step-by-step process of installing backer board in your shower. ### Tools and Materials Required: - Safety goggles - Gloves - Hammer - Utility knife - Circular saw (optional) - Level - Tape measure - Pencil or marker - Backer board screws - Backer board - Thin-set mortar - Notched trowel - Grout - Grout float - Sponge - Clean bucket ### Step 1: Prepare the Shower Area 1. Remove the old shower tiles, fixtures, and hardware. 2. Inspect the shower walls for any damage or deterioration. Repair any issues before proceeding. 3. Ensure that the shower drain is properly positioned and free of debris. ### Step 2: Measure and Cut the Backer Board 1. Measure the height and width of the shower walls. 2. Transfer these measurements to the backer board using a pencil or marker. 3. If necessary, use a circular saw or utility knife to cut the backer board to the desired size. 4. Make sure the cuts are straight and clean. ### Step 3: Apply Thin-Set Mortar 1. Apply a thin layer of thin-set mortar to the shower walls using a notched trowel. 2. Hold the trowel at a 45-degree angle and spread the mortar evenly across the surface. 3. Ensure that the mortar is applied in a consistent thickness. ### Step 4: Install the Backer Board 1. Carefully position the backer board onto the thin-set mortar. 2. Press the backer board firmly into place, ensuring that it is flush with the shower walls. 3. Use a level to check that the backer board is installed straight and plumb. ### Step 5: Secure the Backer Board 1. Drive backer board screws through the backer board and into the shower studs. 2. Space the screws evenly, approximately 8 to 12 inches apart. 3. Ensure that the screws are countersunk slightly below the surface of the backer board. ### Step 6: Tape the Joints 1. Apply a layer of fiberglass mesh tape to the joints between the backer board sheets. 2. Use a thin-set mortar to embed the tape into the joints. 3. Allow the thin-set mortar to dry completely. ### Step 7: Apply a Waterproofing Membrane 1. Apply a waterproofing membrane or liquid waterproofing to the entire surface of the backer board. 2. Follow the manufacturer's instructions for proper application. 3. Allow the waterproofing membrane to dry completely. ### Step 8: Install Shower Tiles 1. Apply a thin layer of thin-set mortar to the back of each shower tile. 2. Press the tile firmly onto the backer board, ensuring that it is level and aligned properly. 3. Continue installing the tiles until the entire wall is covered. ### Step 9: Grout the Shower Tiles 1. Mix the grout according to the manufacturer's instructions. 2. Use a grout float to apply the grout to the joints between the tiles. 3. Press the grout firmly into the joints, ensuring that they are completely filled. 4. Remove excess grout from the surface of the tiles with a damp sponge. ### Step 10: Clean and Seal the Shower 1. Allow the grout to dry completely. 2. Clean the shower with a mild detergent and water. 3. Apply a sealant to the grout joints to protect them from moisture. By following these steps carefully, you can ensure that the backer board in your shower is properly installed, providing a solid and waterproof base for your shower tiles. This will help prevent leaks, moisture damage, and costly repairs in the future.
