This kit is designed for DIY'ers and contractors.

Recommended Waterproofing membrane Square Foot Choice based on typical shower layouts - Choose appropriate selection

Typical Kit Sizes - these are popular sizes that typically correspond to needed SF Square Feet (SF) of WP waterproof membrane
48" x 48" or 32" x 60" or smaller 108 SF
48" x 60" or 48" x 72" or 60" x 60" 135 SF
72" x 72" or 48" x 96" 216 SF
72" x 108" and larger showers and steam rooms 323 SF

This table provides only general guidance. Kit sizes assume membrane will go up the wall high enough out of wet area but not necessarily up to ceiling. You are responsible for calculating how many SF of waterproofing membrane you require or want (many installers go up to ceiling if tiling to ceiling). One method is to calculate exact area to be covered, multiply by 1.08 then round up. Any SF needed beyond the set sizes can be added with the recommended related WP per SF product listing.

Why Is PSC Gen 2 Better?

PSC GEN II Mud Kit Installation

  • Includes all the components required to build an fully-bonded water-tight assembly for tiled showers
  • Ideal for installers experienced with floating their own dry-pack mortar floor, this system is easy as 1,2,3: Set and glue drain flange to plumbing, pack and slope your floor, apply waterproof membrane to all surfaces (Note: you would skip all steps in video related to quick-pitch sticks)
  • Extremely reliable yet easy to construct
  • Can be easily modified to accommodate smaller or larger installations
  • Can be easily modified for non-standard drain locations (e.g. offset or double offset)
  • You build your own single layer dry-pack mortar sloped concrete floor. No need for the second pre-pitch or pre-slope concrete floor
  • Kit improved to include the strongest and most reliable drain flange for membrane systems on the market
  • Drain flange allows the flexibility of multiple adjustment to riser assembly at end of install
  • Riser-Grate assembly includes a construction plug and features locking grout and mortar grooves to ensure the strongest and most reliable final installation
  • Riser threads into super-strong locking ring to provide ultimate strength and security while still allowing adjust-ability
  • Numerous grate color and style choices available that offer easy removal/reinsertion so that integrated hair trap can be frequently and quickly serviced with no small screws to lose
  • Protects floor, corners, edges, curbs and wall cavities against water and vapor penetrations. In steam applications, all surfaces can be protected
  • Protects all surfaces, particularly in joints and corners, from grout cracking or tile instability
  • Installation can use recommended high-quality modified thin-set mortar readily available from multiple manufacturers for better adhesion and elimination of failure possibilities.
  • Install glass tiles and other high-density materials with this system where other unmodified thin-set systems don't allow these materials.
  • Membrane tested at 0.07 PERM rating - much lower than required for steam showers! Other systems require specialized high-cost membrane for steam
  • Installation methods very similar but easier than competing kits - little to no retraining required for contractors
  • If installer accidentally damages membrane, problem can be easily identified and repaired before flood testing or tile installation
  • Materials are backed by an industry standard 10-year warranty. Grates have a lifetime warranty

Note: You will need to obtain dry-pack mortar mix from your local hardware supply. 4 or 5 parts sand - 1 part portland cement is generally recommended.

Why a PSC Gen 2 Mud kit for Contractors and experienced DIY?

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. These kits are far less complicated and far more reliable than the traditional method of having to build a thin pre-slope concrete layer under a rubber liner, then draping and folding an unwieldy rubber liner behind wall board, and then finally floating a second sloped concrete floor over all of that. These kits allow you, the skilled contractor, to float a single sloped dry-pack floor where the waterproof is applied to the TOP. This PSC Gen 2 system will save you a lot of time while allowing your dry-pack skills to be put to work. There is no longer need to spend two days installing rubber liner then following up with liquid waterproofing for the walls.

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 that always have soaking wet concrete between the tile and the buried liner, PSC Gen 2 waterproofing keeps the sloped concrete bone dry. 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.

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 prevents moisture penetration into the walls or floor at all! 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, pack and float your sloped dry-pack mortar floor, and finish by applying waterproofing to all substrates.
