CARE & CLEANING

The surface of your Mustee Fiberglass Bathtub Wall may be cleaned with a mild

soap solution in warm water using a soft cloth. When using a cleaner product,

carefully read the label to ensure that the cleaner is safe for the use on the

material. Stubborn stains may be cleaned using "Soft-Scrub®" by CloroX®, "Tub

& Tile Cleaner"® by Lysol® or a powdered detergent such as "Spic-n-Span". Do

not allow cleaners to sit and soak on the surface. Wipe surface clean and rinse

completely with water immediately after cleaner application. Rinse and dry

overspray on nearby surfaces. Never use abrasive scouring powder or steel wool

pads, as they will dull and scratch the surface.

drill reference holes (prefer one on top, one on side for Side Panels, 2 on top for Center

Panel) into the studs/bracing with the appropriate drill bit for the “deck” screws; drill 1/8” dia.

holes - max. THESE HOLES WILL ALIGN UNIT WHEN YOU ARE READY FOR THE

PERMANENT INSTALL.

With panels temporarily in place, lightly trace along bottom edge of panels onto bathtub with

a pencil. Remove panels and apply a 1/4” bead of silicone sealant all around where panels

contact bathtub (locate approx. 1/4” back from pencil line) see Fig. G.

Hold Center Panel approx. 2” above bathtub flange and in contact with stud faces. Slide panel

down into bead of silicone sealant so that mounting clips lock behind bathtub flange (Fig.F).

Shim panel as required and secure to studs/bracing with “deck” screws through previously

drilled mounting holes. Apply a bead of sealant to one of the vertical grooves on the Center

Panel (Fig. C).

Each Side Panel has a blade (running the full height of the panel) that engages into the

corresponding Center Panel groove. Hold Side Panel approximately 1/2” above Center Panel.

Align and insert blade into groove and lower Side Panel into place. Top edges should be level

(Fig. C). Wipe away any excess silicone sealant that may have seeped out onto the finished

surface. Shim panels (level and plumb) as needed and secure to studs/bracing with "deck"

screws through previously drilled holes.

Apply silicone sealant to remaining Center Panel groove as in previous step and repeat

procedure for remaining Side Panel.

Finish alcove with W/R rated wallboard. Wallboard should cover mounting flanges.

NOTE: Wallboard can either be “back-cut” or stud faces “furred” out (1/8” - 1/4” hardboard

or plywood) to accommodate thickness of mounting flange.

Seal all around on panel seams and where panels meet bathtub and wallboard with a quality

tub/tile sealant.

TOOLS AND MATERIALS* See back cover page B. The Center and Side Panels have a mounting flange that is designed to accept standard “drywall” screws. The positioning of the studs and bracing (see ROUGH-IN FRAMING) have been laid out to give maximum support (horizontally and vertically) behind these flanges. The mounting flanges have pre-marked holes - to avoid cracking the flange, it is recommended that you pre-drill all of the holes with a 5/32” (inch) diameter drill bit.
