4. Replacing an Existing Leaking Shower Pan
An existing leaking shower pan can be replaced using the following
method.
Remove the tile floor and the first course of tile from the wall of the
shower stall using a small sledge hammer, crow bar or pry bar. Be
sure to wear goggles.
Remove all material down to the original subfloor, including the old
shower pan. If the subfloor is wooden, inspect it carefully for rotten
floor boards that will need replacing. If no subfloor is evident, we
recommend that one be installed as described in Section 1. Inspect
the dam area for rotten boards and replace any if necessary. Install
the shower pan material as described previously, but with the following
modifications. Be sure that there is room for a minimum of one-half
inch of mortar plus the thickness of the tile. If this amount of space is
available, then the vinyl shower pan liner does not have to be recessed
flush to the studs. Measure the area to be covered with liner as
described before. The liner need only go up the walls far enough to
meet sound tile and mortar. Tuck the liner up under existing tiles as
far as possible and secure with staples or by tracking. A continuous
bead of butyl rubber caulking should be applied to the area where the
liner meets the existing sound tile and mortar. Test for water tightness
as described previously. Metal building lath is used to back the mortar
for the new tile. Measure lath and cut to fit. Be careful not to puncture
the shower pan liner when placing lath. Install full mortar bed and tile
to industry specifications and local plumbing or building codes,

Shower Pan Joining Instructions
Due to the variety of widths, lengths and heights of shower stalls, gang showers
and similar areas which require waterproofing, it may be necessary to join widths
of PASCO Vinyl Shower Pan Liner. The following instructions must be followed
very carefully to achieve a waterproof seal.
IMPORTANT - Use only PASCO Vinyl Shower Pan Liner Solvent Cement
(Part Number 3008) for joining pan sheets. It is specially formulated to make
a permanent waterproof seal when used as directed. To join sheets allow a
4” minimum overlap. Apply a thin, even coat of cement to both surfaces to be
joined. The entire surface of material to be joined must be covered with cement.
Apply the cement to short lengths of material, not to exceed 3 feet at a time,
Figure 9.
Join cemented surfaces as quickly as possible before cement dries. For long
seams exceeding 6 feet in length, use a weighted, smooth flooring roller to
facilitate bonding of material, Figure 10.
Apply a wide bead of cement to the entire length of the overlap. If material has
been joined outside of the installation area, apply the bead to both top and bottom
edges of the overlap, Figure 11.
Do not disturb or try to peel joined surfaces. The cemented seam should fully
cure in 24 hours. Test for water tightness as described in section 3.
