2-Part Epoxy Repair

• 1). Put on all protective gear.
  
  
• 2). Sand down the cracked areas, using the various grits of the sandpaper. Start with 120-grit and work your way up to the 400-grit. Remove any loose chunks of material.
  
  
• 3). Apply the two-part epoxy. It will self-mix, so there is no need to have to measure and nix components. Work it down into all deeper crevices, using the plastic putty knife. Let it dry for several hours.
  
  
• 4). Apply a second coat if needed to level out the repair area with the rest of the shower base. Let dry for several hours before using the shower.
  
  

Tub and Shower Repair Kit

• 1). Separate the items from the tub and shower repair kit. Kits vary, but usually consist of sandpaper, hardener, catalyst, mixing container or spray bottles, and sometimes color tint.
  
  
• 2). Sand down the affected areas as indicated in the first section.
  
  
• 3). Clean the area with the spray degreaser and rough sponges.
  
  
• 4). Spray on or brush on the hardener. Let dry for several hours. Mix any tint needed and brush it on. Let dry for several hours again.
  
  
• 5). Apply one to two coats of the catalyst, overlapping the application as you go. Let dry for several hours.
