VERY IMPORTANT!

READ THE FOLLOWING BEFORE STARTING INSTALLATION

DO NOT use any brand or version of PRE-MIXED thin-set

mortar with this kit installation or tiling after kit installation.

DO NOT use any thin-set mortar modified or non-modified

that comes pre-made in a bucket or pail. None of these thin-

set mortars will reliably cure with any brand of waterproof

membranes or shower installations. DO NOT use mastics or

other ready-to-use-in-a-bucket type tile adhesives.

DO USE polymer/modified thin-set mortars that are sold as a

dry powder in a bag (typically 50#) that need to be thoroughly

mixed with water to activate and apply.

DO USE a well-known name brand polymer/modified thin-set

mortar to include companies like but not limited to (HB Fuller)

TEC, Laticrete, Mapei, Ardex, (CBP) Custom Building Prod-

Trace another circle inside the existing circle. It is preferable but not absolutely necessary to leave a 1/2” or larger ridge for better drain flange support. You may also use a center point and create a circle with about a 4” diameter. 3.

Your drain pan is usually precut at the warehouse to accommodate the much stronger GEN II drain flange. However if it is not, trim the inside of the pan drain opening to allow for a snug fit of the flange. It should dry fit as seen from the bottom of the pan in this photo. 6.

Literally step on the drain flange to force the locking grooves into the foam pocket to guarantee a perfect seat for final installation. At this point, just leave the flange dry-fitted in place.

Measure the distance between two corners and cut a section of 5” WP band that is about 1 inch less (it’s best to be about 1/2” away from each edge while still allowing for a 2” overlap.) Fold the strip longitudinally and crease it to prepare for install. Apply 3/16” notched modified thin-set mortar to the floor-to-wall joint that you just measured.

When adding an additional overlapping piece of WP membrane, work notched thin-set mortar over the marked out section including an overlapping section on the previously installed membrane. Use the dashed line as a guide for how much overlap of thin-set to provide. Install this an any remaining pieces with the same exact installation procedures. 15.

Whether you have installed the optional foam curb or have built one out of 2x4 lumber covered with wall board or concrete, the curb will also get covered with waterproof membrane. Apply notched modified thinset mortar to all curb surfaces, then apply WP membrane using the position, seat and press techniques used throughout the installation. For curb runs longer than the length of the membrane, add additional pieces while observing the 2 inch overlap rule.

www.prosourcecenter.com Additional Considerations Choosing the highest quality premium modified (latex/polymer) thin-set you can find will make your installation much easier and yield better results. Because of the high cost of shipping heavy materials, most people purchase thin-set mortar and dry-pack mortar components locally. Good quality brand names to look for include but are not limited to TEC, Laticrete, Mapei, Ardex, Custom Building Product (CBP) and others.
