A scratch or chip in a shower tray detracts from the appeal of your showering area. However, this problem is something you can take care of without replacing the entire shower tray. A shower tray repair kit fills in and covers scratches permanently. The job takes just a few minutes to complete, and everything you need is included in the kit. You can find these kits at plumbing stores, home improvement centres and home and garden retailers. Just match the kit colour to your shower colour and you are ready to go.
Clean the damaged area with a household cleaner and a sponge to remove residues, dirt and grease. Rinse the area with water and dry with a towel.
Sand the area with 200-grit sandpaper to remove burrs and splinters from the edges of the crack or scratch. Sandpaper is usually included with the kit, but not always.
Wipe away the sanding residue with your towel or a clean cloth. Make sure the area is free of all residue and dust before you apply the repair compound.
Mix the repair kit hardener with the repair compound, following the mixing ratio supplied by the manufacturer. This ratio varies, but it's usually around 30 to 1. Stir the compound several times to thoroughly mix the hardener.
Apply the compound to the damaged area using the provided spreader. Allow the compound to dry for 12 to 24 hours. Sand the repair down with 200-grit sandpaper. Paint with acrylic spray paint to match your shower tray.
