STEP 7Place cement board or equivalent on top of showerbase flange and secure to studwall.Apply tile (or other finishing material) leaving a 1/8" gapbetween the finishing material and the shower baseflange lip. Seal this gap with silicone sealant. Leave aminimum 1/4" gap at the back and front corners of theshower base to allow drainage from leakage throughunsealed tiled grout.BASE INSTALLATIONCLEAN UP AFTER BASE INSTALLATIONTo avoid dulling and scratching the acrylic surface of the base, never use abrasive cleaners. A mild liquid detergentand warm water clean soiled surfaces.Remove spilled plaster with a wood or plastic edge. Metal tools scratch the surface. Spots left by plaster or groutcan be removed if lightly rubbed with detergent on a damp cloth or sponge.Paint, tar, or other difficult stains can be removed with paint thinner, turpentine, or isopropyl alcohol (rubbingalcohol).Minor scratches which do not penetrate the color finish can be removed by lightly sanding with 600-grit wet/drysandpaper. You can restore the glossy finish to the acrylic surface of the base with a special compound, Meguiar’s#10 Mirror Glaze. If not available, use automotive rubbing compound followed by an application of automotive pastewax.Major scratches and gouges which penetrate the acrylic surface require refinishing.
