Material & Characteristics Sheet molded compound (SMC) is a thermoset material consisting of binding resins, crushed stone, colorants and fiberglass reinforced fibers. SMC requires heat and pressure to form into shape. The internal glass fibers give thermoset SMC it’s structural strength and the finished product is extremely stable at high or low temperatures. The color is molded throughout the part and the hard surface has a high impact tolerance. The SMC is chemical and stain resistant as tested to ANSI-Z standards with a classification of Type I (its highest rating). SMC flows throughout the mold cavity during the molding process allowing structural ribs, molded- in drains and slip resistant floor patterns to be incorporated as an integral part of the product. The thickness of the part can be accurately controlled. Mustee Durabase Shower Floor SMC Fiberglass Production Process The matched metal mold is mounted in a hydraulic press, capable of generating in excess of 1,000 tons of pressure. The SMC compound is placed between both halves of a highly polished, chrome plated, tool steel mold. The mold is heated and closed applying pressure for a pre-determined period of time. The mold is decompressed and the molded casting removed. The heat and pressure molecularly fuse the compound to create the finish product.

Front Threshold The Durabase Shower Floor threshold has been modified with a reverse tapper of degrees, angling it into the shower floor. The reference for proper draining was the Uniform Plumbing Code – IAPMO/ANSI UPC Section which states that the finished floor of the receptor shall slope uniformly from the sides toward the drain not less than one-quarter (1/4) inch per foot (1°) nor more than one-half (1/2) inch per foot (2°). Therefore the 2.5° tapper on the revised threshold (2 ½” wide) is more than adequate to direct the flow of water. Further modification to the threshold is an addition of a barrier rib on the inside of the tiling flange. With addition taper to the recess. The barrier rib is a hidden behind the tile for a clean finished appearance.

The sides of the pedal are tapered for easy cleaning. The pedals themselves all point towards the center of the shower floor directing the water in an unrestricted flow to the drain. The majority of the floor surface is flat for easy cleaning. Section View of Threshold Modifications 2.5° Durabase Shower Floor
