Step-by-Step Installation Guide
1. Preparing the Shower Pan:
- Clean the Shower Pan: Remove any debris or dirt from the shower pan area.
- Install the Drain: Follow the manufacturer's instructions for installing the shower drain. Make sure it's level and properly secured.
2. Installing the Mortar Bed:
- Mix the Mortar: Prepare the mortar bed according to the manufacturer's instructions.
- Apply the Mortar: Spread the mortar evenly across the shower pan floor, ensuring a smooth and level surface.
- Install the Drain: Once the mortar bed is partially dry, install the shower drain, ensuring it's securely positioned and level.
3. Installing the Shower Pan Liner:
- Cut the Liner: Use a utility knife to cut the liner to size, leaving approximately 2 inches of overlap around the perimeter of the shower pan.
- Secure the Liner: Attach the liner to the shower pan walls using a staple gun. Staple it every 6-8 inches, ensuring a tight and secure fit.
- Check for Leaks: Before installing the cement board, carefully check for any leaks by pouring water onto the liner and observing if it pools in any areas.
4. Installing the Cement Board:
- Cut the Cement Board: Use a utility knife or a specialized cement board cutter to cut the cement board to fit the shower pan floor.
- Attach the Cement Board: Apply thin-set mortar to the back of the cement board and attach it securely to the shower pan floor, ensuring it's level with the drain.
- Seal the Joints: Use a waterproof sealant to seal the gaps between the cement board and the shower pan walls.
5. Final Steps:
- Finish the Shower Floor: You can now apply thin-set mortar to the cement board and install your chosen shower floor tiles.
