Pre-Pitch™ is a unique, stay-in-place spreading tool designed for use underneath shower pan liners. The first product to be installed, Pre-Pitch™ creates the proper sub floor pitch (1/4" per 12" run) needed to direct water flow towards the weep holes that are an integral part of shower floor drains.
By having a pitch under the pan liner, water that passes through the mud bed is not directed to the weep holes instead of being trapped between the mud bed and the liner where many mold and mildew related issues often originate. The plastic Pre-Pitch™ sticks have holes in their vertical web which helps to act as reinforcement and are easily cut with a hacksaw, PVC cutter, or dry diamond blade.
For wood subfloors, Pre-Pitch™ can be screwed or nailed in place. For concrete subfloors, use two sided tape. Subfloor must be level, sound, and properly prepared prior to installing Pre-Pitch™.
