Step-by-Step Guide to Repairing a Cracked RV Shower Pan

  1. Preparation: Start by cleaning the shower pan thoroughly using a cleaning solution and a scrub brush. Remove any dirt, grime, or residue from the surface. Rinse the pan with water and allow it to dry completely.
  2. Preparing the Crack: Use sandpaper (grit: 80) to sand down the cracked area gently. This process will help create a rough surface for better adhesion. Clean the sanded area with acetone or rubbing alcohol to remove any remaining debris or dust.
  3. Applying Epoxy Resin or Fiberglass Repair Kit: Follow the instructions provided with the epoxy resin or fiberglass repair kit. Mix the resin or hardener as directed and apply it to the crack using an applicator brush or roller. Ensure that the crack is entirely covered with the resin or fiberglass material.
  4. Smoothing and Shaping: Use a putty knife to smooth out the repaired area and shape it to match the surrounding surface. Remove any excess resin or fiberglass material. Allow the repair to dry completely as per the manufacturer’s instructions.
  5. Sanding and Finishing: Once the repair is dry, use sandpaper with gradually increasing grits (120 and 220) to sand down the repaired area. This process will help achieve a smooth finish. Clean the sanded area with a damp cloth or sponge.
  6. Sealing the Repair: Apply a waterproof sealant to the repaired area, extending it slightly beyond the edges of the repair. This step will ensure a watertight seal and prevent future leaks. Allow the sealant to dry completely.
  7. Reassembling and Testing: Reinstall any removed components, such as drain covers or shower fixtures. Perform a water test to check for leaks. Run water in the shower pan and inspect the repaired area for any signs of leakage. If no leaks are detected, congratulations! You have successfully repaired your cracked RV shower pan.
