Pre-Pitch™ is a unique, stay-in-place spreading tool designed for use underneath shower pan liners. Pre-Pitch™ is a unique tool that creates the proper sub floor slope needed underneath the pan liner to manipulate the water towards the weep holes that are integral part of shower floor drains. By having a pitch under the pan liner, water that passes through the mud bed is now directed to the weep holes instead of being trapped between the mud bed and the liner. This ‘ponding’ or collection of water is where many mold and mildew related issues originate.
Easily cut with hacksaw, PVC cutters or grinder.
Use on wood sub-flooring or concrete floors.
Economical, lightweight non-rotting plastic.
