The first phase of waterproofing a shower pan is to create a slope 1/4 inch per foot that goes towards the drain. We do this by adding a mortar mix. The mortar is installed dry, allowing us to move it with a towel to give it the proper pitch. After wetting the mortar just enough to cure, we install the hot mop over the mix in minutes.
Before we begin, the shower pan must have a proper shower drain and proper blocking. After this step, we then cover any areas outside the shower pan to ensure a clean hot mop. Next, we add the pre-slope, remove the top flange, and then add Henry's Cold Tar to create a sandwich effect, resulting in a watertight seal. The hot mop consists of 3 layers of felt #15 paper, which sits between the two drain flanges. We add liquid asphalt before, between, and after every layer of felt paper. By following this process, we make sure that every corner is tight, and as squared as possible to ease the process for the tile man to install the Hardiebacker (a cement board that must be installed before tiling). After the installation of the three layers of felt, we then add yellow fiberglass mesh to each corner. This strengthens the hot mop and prohibits it from breaking from any construction or movement thereafter.
After adding the yellow fiberglass mesh, we tighten the top flange back into place and then give the shower pan its last coat. During the last coat, we mop over the entire shower without covering the weep holes of the drain. By not covering the weep holes, any water that reaches the hot mop can find its way out to the drain line. Our project is now complete, with a 100% guarantee to hold water and pass any city inspection.
