BEFORE YOU BEGIN |
| CHECKLIST |

CHECK
LOCAL PLUMBING CODE to determine choice of 30 or 40 mil Composeal.
(Example: UPC requires 15 lb. felt under 30 mil pan, City of Los Angeles doesn't). |
| |
DRAIN
must be two-part clamping drain with weep holes. |
| |
SUBSTRATE
must be sloped to drain 1/4" per foot. If not sloped, see following instructions for
ways to slope floor. |
| |
PRE-FORMED
CURB PROTECTORS: UPC requires these at curb corners. Composeal three-way
corners/ curb protectors are available at Composeal delaers. |
| |
COMPOSEAL
FLEXIBLE PVC CEMENT to weld corner/ curb protectors in place, and for
welding seams. |
| |
PROVIDE
BLOCKING at base of shower walls to support and affix Composeal Shower
Pan. |
| |
PROTECTIVE
COVER. Have available cardboard, drywall or such to cover Composeal
installation. |
| |
HAVE
SUFFICIENT COMPOSEAL ON HAND FOR JOB. Composeal is available in 4', 5',
and 6' widths. Assuming a 6" high curb, allow a minimum wall turn-up of 9"
(3" above curb height) and a minimum of 16" for wrapping around entire curb. |
|
HOW TO INSTALL |
 |
| 1 |
Continuous blocking at
base of studs. |
 |
| 2 |

stall |
 |
| 3 |
Weld both sides of seams with Flexible PVC
Cement |
 |
| 4 |
Roll seams after cement becomes tacky |
 |
| 5 |
Nail (or screw) pan to studs or blocking |
 |
| 6 |
Fold corners and nail or screw "dog
ear" to stud |
 |
| 7 |
Pre-formed corners in three corner/curb
configurations |
 |
| 8 |
Apply Flexibe PVC cement to both sides of
corner weld |
 |
| 9 |
Weld Pre-formed corners/curb protectors in
place |
|
CUT
and PLACE PAN
Lay out and cut your Composeal Shower Pan outside the
shower stall (see fig. 2). Measure the inside dimensions of the shower
floor and add a minimum of nine inches for each wall. Be sure to allow enough material to
extend up and over entire shower curb, including the front of the curb. When necessary,
seaming is easily accomplished using Composeal Flexible PVC Cement (see fig. 3).
Lay sheets with an overlap of 2" with upper lap edge toward direction of drainage.
Apply the PVC Cement to both surfaces. Place surfaces together after becoming tacky (about
2 minutes) and press or roll seam (fig. 4).
Carry pan into shower and place against back wall.
ATTACH PAN and PRE-FORMED
CORNERS
Place top edge of shower pan at least 3" above top of shower curb . Composeal may be
fastened directly to wood studs using roofing nails, or to wood or metal studs using
screws and washers (see fig. 5). Make sure no penetrations occur less
than 2" above top of dam. Pan is not to be attached to the sloped bed or sub-floor.
If drywall or cement backer board is to be installed over the studs, 1/4" shims
should be attached to the stud faces. This will space the board out to extend straight
down and over the pan. If metal lath is to be installed to provide for a mortar
installation on the walls, then no shims are needed, the paper and lath simply extend down
and over the pan. Remember, no penetrations of fasteners for the pan, board or lath lower
than 2" above the shower curb.
Inside corners should be folded with a "dog ear" preferably tucked behind and
nailed at the top edge (see fig. 6).
At outside corners and corners which can not be accommodated by folding, use Composeal's
Pre-Formed 3-way corner/curb protector (see fig 7). This versatile
accessory helps to create neat corners in difficult details. Pre-Formed Corners are a must
at curb and seat locations. Use seaming procedure discussed above to weld on corners/curb
protectors. Corners must be applied in place (see figs. 8 & 9).
TREAT DRAIN AREA and FLOOD TEST
After pan is attached and all corners are secure, carefully
locate drain hole, and trim for drain exactly to size of opening (see fig. 10).
Do not trim out to bolt holes. Bolt holes should be pierced with a nail or punched to
accommodate bolts with a tight fit (see fig. 11).
Lift pan to apply an even bead of Compotite Elasti-Seal under pan at bottom flange of
drain (see fig. 12). Carefully join the two flanges and firmly bolt them
together. Plug drain using a proper test plug and fill to flood level (top of curb) (see
fig. 13). Let stand for 24 hours to determine that pan is well installed and
undamaged.
PROTECT / INSTALL MUD BED
At this point, other trades may need to have access to the
shower area to do their work (lathers, plasterers, or drywallers). So be sure to protect
the entire pan with heavy cardboard, plywood or drywall.
Visually inspect to make sure no damage has occurred.
If you have any doubt, water test again. If a
puncture is located, it may be patched with a
small piece of Composeal.
