Installing a Kerdi Shower Pan on Concrete
A Kerdi shower pan is a great way to create a waterproof and durable shower base. It's made from a waterproof membrane that's adhered to a thin layer of concrete. This makes it a great choice for both new construction and shower renovations.
Here's a step-by-step guide on how to install a Kerdi shower pan on concrete:
Materials You'll Need:
- Kerdi Shower Pan: Choose the size and shape that fits your shower area.
- Kerdi-Fix Adhesive: A strong, waterproof adhesive specifically designed for Kerdi products.
- Kerdi-Band: A flexible waterproof membrane that creates a watertight seal around corners and edges.
- Kerdi-Drain: A waterproof drain that is compatible with Kerdi products.
- Concrete: You'll need a layer of concrete to create a level surface for the shower pan.
- Mortar: For leveling and supporting the shower pan.
- Tools: Trowel, tape measure, utility knife, level, drill, and a mixer for concrete.
Installation Steps:
- Prepare the Subfloor: The subfloor must be level and smooth. If it's uneven, you'll need to level it with mortar. Be sure to allow the mortar to fully dry before proceeding.
- Install the Kerdi-Drain: Center the drain in the shower area and mark the location. Cut a hole in the concrete for the drain using a drill and a hole saw. Use a level to make sure the drain is installed perfectly level.
- Apply the Kerdi-Fix Adhesive: Apply a thick layer of Kerdi-Fix adhesive to the subfloor. Make sure to cover the entire surface evenly.
- Install the Kerdi Shower Pan: Carefully lay the Kerdi shower pan on top of the adhesive. Use a trowel to smooth out any air bubbles.
- Secure the Kerdi Shower Pan: Use additional Kerdi-Fix adhesive around the perimeter of the shower pan. Apply it with a trowel, ensuring a tight seal.
- Install the Kerdi-Band: Use Kerdi-Band to create a waterproof seal around the corners and edges of the shower pan. Apply it with Kerdi-Fix adhesive.
- Let the Adhesive Dry: Allow the Kerdi-Fix adhesive to dry completely according to the manufacturer's instructions.
- Finish with Tile: Once the Kerdi shower pan is installed and the adhesive is dry, you can begin tiling the shower floor.
Tips for Success:
- Read the Manufacturer's Instructions: Always follow the manufacturer's instructions for the Kerdi products.
- Use the Correct Adhesive: Using the wrong type of adhesive can compromise the waterproofing of your shower.
- Make Sure the Drain is Level: A level drain is crucial for proper water drainage.
- Allow the Adhesive to Dry Completely: Avoid tiling before the Kerdi-Fix adhesive has fully dried.
Conclusion:
Installing a Kerdi shower pan on concrete can be a straightforward process if you follow these steps carefully. It's a great way to create a durable and waterproof shower base that will stand the test of time.
