Refinishing a plastic shower floor is a great way to restore its beauty and durability without the hassle of a full replacement. The process involves cleaning the surface, patching up any holes or cracks, and applying a new finish. This can be done using a DIY kit, which typically includes epoxy, hardener, application tools, and cleaning supplies. Alternatively, a professional can be hired to prep the surface and apply a glaze, which will cure to a durable finish within a few days. While a DIY kit is more affordable and convenient, a professional refinishing job will last longer.

What You'll Learn
Cleaning the shower floor
Before you begin resurfacing your plastic shower floor, it is important to clean the surface thoroughly. This step is crucial as it ensures that the refinishing coat adheres properly and that your shower floor is free of any dirt, grime, or soap scum.
Start by covering the shower faucets and showerhead with plastic bags, securing them with rubber bands. This will prevent water from dripping onto the surface during the cleaning process. Let the surface dry thoroughly. You can use a heat gun to accelerate the drying process. Once dry, wipe down the surface with paper towels and then use a tack cloth for a final clean.
Next, you'll want to mask off the floor around the shower base and the rest of the shower stall. Use low-stick painter's tape to cover the caulk and any areas that will not be refinished. If the caulk is in poor condition, consider removing and replacing it. Put on protective gear, such as latex gloves and a respirator, before handling any chemicals or beginning the scraping process.
Use a sharp razor scraper to remove layers of caked-on soap scum and built-up dirt from the shower floor. Scrape over all the smooth parts of the shower pan, including the curb, but avoid scraping any textured portions. Use the razor blade to carefully remove any caulking on the curb, sides, or floor of the shower base. This step ensures that you create a smooth surface for the new coating to be applied.
After scraping, mix a cleaning solution to wash the shower base. You can use trisodium phosphate (TSP), mixing 1/2 cup of TSP with a gallon of warm water. Wash the shower base thoroughly with this solution and then rinse well. You can also use abrasive cleansers or etching powder, followed by a damp paper towel to remove any remaining residue. Ensure that you do not leave any soap scum behind as it will weaken the refinishing coat.
Finally, once the shower floor is clean and dry, lightly sand down the surface. This step helps create a dull surface, which will improve the adhesion of the refinishing coat. Your shower floor is now ready for the next steps of the resurfacing process.

Preparing the surface
Firstly, it is crucial to thoroughly clean the shower floor. This involves removing all traces of soap scum, dirt, and grime. Use abrasive cleansers and a razor blade to scrape away any built-up residue. Be sure to follow safety precautions and use gloves and eye protection. You can use a damp paper towel to collect the shavings and dispose of them in a waste can.
Next, you'll want to mask off the area. Cover the showerhead and faucets with plastic bags to prevent any water from dripping onto the surface. Secure the bags with rubber bands. Apply low-stick painter's tape to any areas that will not be refinished, such as the caulk and surrounding walls. This will protect these areas from the refinishing products.
Once the area is masked off, it's time to prepare the surface. Start by scuffing the surface with sandpaper, especially around any cracks or damaged areas. This will create a rough texture that will help the new coating adhere better. If there are any large holes or cracks, you may need to apply a repair kit, which typically includes epoxy filler and application tools. Follow the instructions on the kit to ensure a proper repair.
After the repairs are complete and the surface is sufficiently scuffed, it's time to apply a primer. Primers are often included in refinishing kits or can be purchased separately. Be sure to follow the instructions on the product for proper application. The primer will help create a smooth base for the new coating and ensure better adhesion.
Finally, some refinishing kits may include an etching powder or recommend etching as a preparation step. This process involves rubbing the powder onto the surface to remove any remaining gloss, creating a dull finish. A dull surface will enhance the adhesion of the new coating. Always refer to the specific instructions provided with your chosen refinishing kit for the best results.

Filling holes and cracks
For small holes and cracks, begin by scuffing the area with 220-grit wet/dry sandpaper. Then, mix the filler and hardener according to the directions provided with your chosen kit. Spread the filler onto the holes with the provided applicator or a plastic putty knife. Scrape off any excess filler and sand the repair flat once the resin sets.
For hairline cracks, it is recommended to drill a 3/8-inch stop hole at both ends to prevent the crack from spreading further. Apply epoxy to the crack and scrape it level.
To repair larger holes, start by scuffing the area around the hole with sandpaper. Apply epoxy to the perimeter and lay a piece of fiberglass mesh cloth over the hole. Press the cloth into the epoxy and let it set. Apply one or two more coats of epoxy over the cloth, scraping it level each time. Sand the repair flat after the final coat sets.
After filling and patching any holes or cracks, you can proceed with the rest of the refinishing process, which may include applying a primer and one or two top finish coats. It is important to follow the specific instructions provided with your chosen refinishing kit for the best results.

Applying the coating
Once you have cleaned and prepared the surface of your shower floor, you can begin applying the coating.
First, cover the tub and shower faucets with plastic bags, securing them with rubber bands. No water should touch the surface from this point on. Let the surface dry thoroughly. You can accelerate the drying process by waving a heat gun over the tub. Wipe down the surface with paper towels and then a tack cloth.
When the tub and surrounding areas are completely dry, apply low-stick painter's tape to any areas that will not be refinished, such as the caulk. Put on latex gloves and a respirator.
Now you are ready to begin applying the coating. Use a roller to apply the coating to the floor of the shower, and switch to a sponge brush to apply the coating to the walls and any areas that cannot be reached with the roller. Lightly dab the sponge brush into the coating and run it parallel to the painter's tape. After the first coat, immediately begin the second coat. Follow the roller coat with the sponge brush again.
Keep a fan running for a full day after applying the coating. After 24 hours, carefully remove the painter's tape by pulling it away at a 90-degree angle. Wait another two days before using the shower.
