Master Bath Remodel - Day 4

DAY 4 - Installing the shower liner

Photo 1 - Measure the dimensions of the shower flor and mark it out on
the sheet of CPE waterproof membrane using a felt tipped marker.
Make a floor outline, adding an additional 8" for each wall and 16" for the curb end.
Create a reinforced drain (extra circular piece of CPE membrane)
It's roughly 2" larger than the drain flange.
Use CPE membrane solvent glue to weld it into place and reinforce the seal at the drain.
PHOTO 2 - Cut out the membrane using a utility knife and straightedge.
Coat the pre pan, curb and perimeter blocking with laminating adhesive,
then apply CPE sealant around the drain.
Set the membrane over the pre pan so the
PHOTO 3 and PHOTO 4
Working from the drain to the walls, carefully
smooth out any bubbles from under the membrane.
Tuck the membrane tight into each corner, folding extra material.
Apply CPE solvent glue to one side, press the flap flat,
then staple in place. Staple only the top edge of the membrane to the blocking
DO NOT STAPLE BELOW THE TOP OF THE CURB OR ON THE CURB ITSELF!

After the membrane has been installed, carefully cut away
enough of the membrane to expose the drain and allow the middle drain piece to fit in place.
Remove drain bolts, the position the middle drain piece over the bolt holes.
Reinstall the bolts, tighening to create a watertight seal.

Test the shower for leaks overnight.

YEAH - No leaks!
