Shower trays are a good drainage solution for shower stalls. These small, waterproof stone, tile or plastic floor pieces fit right inside the shower for a decorative touch to any stall. Shower trays offer pizazz and a cosy feel in showers where a full tub is impractical. If you have an old or drably coloured tray, however, it actually detracts from the shower's overall appearance. Fortunately, you can paint a dull shower tray with just one day's work.
Clean tile and plastic shower trays with a rag and trisodium phosphate cleanser (TSP). Clean stonework shower trays with a rag and muriatic etching solution, because even small deposits of dirt or mildew can limit primer and paint adhesion.
Rinse the cleaning solution off the surface. If your shower is fully built and operational, just run the showerhead for two or three minutes to rinse off excess cleaning residue. For a non-functional shower, rinse with a garden hose or well-saturated rag.
Dry the shower tray with a towel.
Prime plastic and tile surfaces with bonding primer and a medium-nap roller. Bonding primer sticks well to slick plastic and tile surfaces to create better paint adhesion. Most masonry shower trays are already rough enough for easy painting and don't need priming.
Apply nonslip epoxy paint to the shower tray, using a medium-nap roller. Nonslip epoxy paint is available at most hardware stores and provides a safer nonslip coating when compared to normal epoxy mixed with sand or other textures. Epoxy paint is thick and usually covers in just one coat, but you can add a second coat after two hours if you notice bare spots.
Do not use the freshly painted shower for at least 24 hours.
