Why PSC Pro Mud Kit?

Rather than utilizing a pre-formed pan, these kits have been created to allow you to easily design and build your own custom pan with a single sloped layer of dry-pack mortar and dictate a customized drain location of your choice. These kits are particularly useful if your shower floor area is not a standard size, drain layout, or will include a complex shape. The kits are far less complicated than traditional sloped mud - rubber liner - sloped mud method that required advanced skills and additional installation time. Pro Advanced Mud kits make it easy for you to create a custom-sloped pan using the dry-pack mortar method with less concrete, less time and complete accuracy.

PSC Pro kit waterproofing doesn't just end at the pan like a rubber liner! This system seamlessly waterproofs from the floor area to the walls and curb barrier as well! Unlike rubber-liner installs where grout typically cracks in the joints and corners, the WP waterproofing membrane in this PSC Pro kit provides anti-crack protection. The installer can use modern high-performance grout throughout the entire tile installation without fear of grout cracking issues. The included Quick-pitch sticks help you ensure a quick and easy construction of a correctly sloped dry-packed mud pan.

Compared to older mortar-pan methods that required the tedious labor involved with two sloped floors and a buried vinyl/rubber liner, our modern PSC Pro Mud Kit creates a much faster, easier and fool-proof installation that utilizes superior "surface" membrane protection and next-generation drain systems. Continuous membrane protection from the drain throughout the pan area and continuously up the walls prevents not only damaging leaks but also moisture penetration into the walls. No moisture in the walls means no lingering moisture that can cause structural damage over time or fuel mold and mildew problems in the wall tile. Very high-moisture shower enclosures or steam showers can be installed with membrane

Unlike rubber liners that have to install under the wall board and cause the wall board to "bow" out, our WP surface membrane protects from the top. This allows you to build all of your substrates ahead of time, get them square, flat, level and plumb before you start the waterproofing process. The waterproofing membrane easily bridges and controls expansion gaps you will need between each wall board section.

The latest update now includes the PSC Pro GEN II drain flange. This flange features factory heat-bonded fleece to allow bonding of WP waterproofing membrane directly to flange without the need for an adapter. This flange has been specifically designed to allow for the easiest mud floor install ever! It's as simple as 1,2,3. Seat the flange to the sub-floor and glue into 2" plumbing, lay the quick-pitch sticks around the flange and pack the floor, and finish by applying waterproofing to all substrates.

The Pro Advanced Custom Shower Kit package includes:

  1. 8 Quick-Pitch Standard sticks. More may be ordered as needed.
  2. Total of 108 sq. ft of Waterproofing Membrane. More may be ordered as needed.
  3. 1 - 33' x 5" Waterproofing Joint Strip. More may be ordered as needed.
