Can I Use Schluter Shower Pans with Integrated Kerdi Waterproofing on a Sloping Subfloor?

If you have a sloping subfloor and want to install a Schluter shower pan with integrated Kerdi waterproofing, you’ve come to the right place.

Can You Use Schluter Shower Pans on a Sloping Subfloor?

Yes, you can use Schluter shower pans on a sloping subfloor. However, there are some important considerations to keep in mind to ensure a successful installation.

Assess the Subfloor

Before installing the Schluter shower pan, assess the subfloor to determine the slope and any necessary modifications.

  • Check the subfloor’s slope by placing a spirit level along the longest edge. If the subfloor slope exceeds 1/4 inch per foot, you may need to adjust it.
  • Check for any cracks, gaps, or unevenness in the subfloor. If you find any, you’ll need to filler and level the subfloor before proceeding.

Schluter’s Recommendations

Schluter recommends the following steps to ensure successful installation on a sloping subfloor:

  • Ensure the bathroom’s drainage system is designed to handle the slope of the subfloor. This may require adjusting the drainpipe’s pitch or installing a drain assembly with a built-in slope shield.
  • Use Schluter’s Kerdi-LT or Kerdi-DF products to create a level, waterproofing surface over the sloping subfloor.
  • Install the shower pan and tile over the Kerdi-LT or Kerdi-DF, taking care to maintain a level surface.
  • Ensure the shower pan’s floor and walls are properly waterproofed to prevent leaks.

By following Schluter’s recommendations and assessing the subfloor’s slope and condition, you can successfully install a Schluter shower pan with integrated Kerdi waterproofing on a sloping subfloor.

How Do I Ensure a Watertight Seal When Using Schluter Shower Pans with Kerdi Waterproofing?

When installing Schluter shower pans, it’s crucial to ensure a watertight seal to prevent water damage and prevent leaks. One way to achieve this is by using Kerdi waterproofing membrane. Here’s a step-by-step guide to help you get it right:

Preparation is Key

Before applying the Kerdi membrane, make sure your shower pan is clean, dry, and free of any debris or old adhesive. Remove any existing membranes or coatings, and allow the surface to dry completely.

Applying the Kerdi Membrane

  • Use a notched trowel to spread a thin layer of Schluter-DITRA over the shower pan, holding the trowel at a 45-degree angle.
  • Press the Kerdi membrane firmly onto the DITRA, starting from the center and working your way outward. Use a roller to ensure the membrane is securely adhered.
  • Use a joiner to connect the membrane at the seams, making sure to press firmly and smooth out any air pockets.

Securing the Membrane

  • Use a 12:1 mix of Schluter-Spatula and water to create a bonding agent. Apply this mixture to the membrane, making sure to cover the entire surface.
  • Use a notched trowel to spread the bonding agent, working in small sections. Smooth out the surface with a clean, damp cloth.

Final Checks

  • Inspect the membrane for any air pockets or gaps. Smooth out any imperfections with a clean, damp cloth.
  • Verify that the membrane is securely adhered to the shower pan and that the seams are sealed.

By following these steps, you can ensure a watertight seal with your Schluter shower pan and Kerdi waterproofing membrane. With proper installation and maintenance, you’ll enjoy a leak-free showering experience for years to come.
