What kind of paint do you use on a shower floor?

Answer SVG
Answer
For painting a shower floor, the best option is to use an epoxy floor paint. Epoxy paints are highly durable, waterproof, and resistant to moisture, making them ideal for shower floors that are constantly exposed to water.12

Preparing the Shower Floor

  • Thoroughly clean the concrete shower floor using a degreaser like trisodium phosphate (TSP) to remove any grease, oil, or dirt that could prevent proper adhesion.1
  • Repair any cracks or dips in the concrete with mortar and smooth the surface using a wire brush or sandpaper.1
  • Apply a concrete etcher or epoxy primer to help the epoxy paint adhere properly.1

Applying Epoxy Paint

  • Use a high-quality two-part epoxy floor paint specifically designed for concrete surfaces and bathrooms.12
  • Apply the epoxy paint with a roller, starting from the center and working outwards.1
  • Allow the first coat to dry completely according to the manufacturer's instructions before applying a second coat for better coverage and durability.1
  • Consider adding an anti-slip additive or grit to the epoxy paint to increase traction and prevent slips on the wet shower floor.2

Finishing and Maintenance

  • Apply a clear epoxy sealer over the painted surface for added protection and a glossy finish (optional).1
  • Allow the painted floor to cure completely, typically 5-7 days, before using the shower.1
  • Regularly clean the painted floor with a mild detergent to prevent soap scum and mineral buildup, which can degrade the epoxy over time.1
It's important to follow the manufacturer's instructions carefully for surface preparation, application, and curing times to ensure a long-lasting and durable finish on your shower floor.12
