The Whole Process By: Harry Dunbar
The pre-sloped mortar bed is ready for the liner to be installed. The purpose of the sloped mortar bed under the liner is to direct water to the weep holes located in the drain assembly.
Remove the upper sections of the drain and leave the bolts hand tightened in the threaded holes so that sand and dirt can't enter and cause an obstruction.
After the pre-sloped mortar bed is scraped and swept clean, lay out the liner material centered on the floor.
Tuck the material into the corners and edges so that voids are absent. Fold in the corners where necessary and in such a way so as not to inhibit the cement board panels from setting tight to the studs. Whatever works ... works. It doesn't have to be pretty.
Attach with a few staples ONLY near the top of the liner and into the studs.
Attach the liner material with staples .... ONLY ONTO THE OUTSIDE of the curb.
The excess liner shouldn't be cut off if it can be helped. In this case where I have unwanted material (where the curb meets the wall), I just fold it under. See next photo.
After the liner is properly installed, it's time to locate the drain. Feel for the 4 bolts and carefully cut around each bolt and then the drain hole.
Cut away liner material where ever the weep holes are located on the drain assembly. There are various designs for shower drains, this one is a better quality and makes it easy to locate the weep holes which in this case are 8 total. There are 2 between each bolt.
Fit the top ring on and check that the weep holes are unobstructed.
If you're happy with the job so far ... it's time to attach the upper section of the drain.
Apply a small bead of caulking under the liner on the OUTSIDE edge of the flange perimeter. If you apply too much it may block some of your weep holes, so be careful.
Attach the top section of the drain, screw the trap into the assembly and admire your work. Notice the 2 weep holes visible between the bolts at the front.
