Repairing Clear Coat On A Shower Pan: A Diy Guide

Shower pans are typically made from acrylic, ABS, or fibreglass, and they are easier to clean than tiled shower floors. However, they are prone to cracking and chipping, which can be repaired using a fibreglass/acrylic repair kit. This involves cleaning the area, roughening the surface, applying the filler paste, and sanding down the repaired area. The cost of repairing a shower pan ranges from $20 to $240, depending on the extent of the damage and whether a professional is hired.

Repairing a cracked or damaged shower pan

A cracked or damaged shower pan can be repaired by following these steps:

Step 1: Assess the Damage

The first step is to assess the extent of the damage. Superficial chips, cracks, and scratches may only require simple filling and refinishing. However, for large cracks or holes, it is recommended to consult a professional to address any underlying problems and add extra support to the structure before patching and refinishing the shower pan.

Step 2: Prepare the Area

Before beginning any repair work, it is important to clean the area thoroughly. Use household cleaners, such as rubbing alcohol or acetone, to remove any dirt, soap scum, or glass fibers from the surface. If the damage is due to a lack of support, you may need to drill small holes in the shower pan and inject two-component foam for extra support.

Step 3: Repair the Damage

For small cracks or holes, use a fiberglass repair kit to fill in the damage. Follow the instructions on the kit to mix the resin putty and hardener, and use a mixing stick to apply the mixture to the damaged area. Allow the mixture to set for 2-3 hours or longer, depending on the size of the crack or hole. Once set, use sandpaper to smooth out the surface.

For larger holes or cracks, you may need to use fiberglass mesh or cloth to provide additional support. Cut the mesh to fit slightly larger than the hole or crack, and lay it over the damaged area. Apply the resin mixture on top of the mesh and smooth it out. Allow it to set and then sand the area to create a smooth surface.

Step 4: Refinish the Surface

Once the repair is complete and the surface is smooth, use a finishing polish or a refinishing kit to blend the patched area with the rest of the shower pan. This will help create a seamless and uniform appearance.

Step 5: Maintenance and Prevention

To extend the life of your shower pan, regular cleaning with mild soap or a paste of baking soda and water is recommended. Avoid using abrasive cleaners as they can damage the surface. Additionally, consider using automotive finishing products designed for fiberglass to maintain the luster of the shower pan.

Using an epoxy kit to fix minor damage

Using an epoxy kit is a straightforward way to repair minor damage to a shower pan. Epoxy kits are readily available at most home improvement stores and are an affordable option to repair cracks, chips, and scratches. The process is simple and can be completed in one day, with the majority of the time spent waiting for the compound to dry.

Before beginning the repair, it is important to assess the extent of the damage. For larger cracks and chips, it may be necessary to drill shallow holes and fill them with two-component foam for extra support. Additionally, fiberglass mesh can be used to reinforce the epoxy and prevent dimpling.

Once the necessary preparations have been made, the repair process can begin. First, clean the damaged area with a household cleaner and a sponge. It is important to ensure that the area is free of any oils, soap scum, and glass fibers, so use a suitable solvent such as rubbing alcohol or acetone.

Now, it's time to mix the epoxy. Put on your protective gear, including goggles, a respirator or mask, and gloves. Follow the instructions provided with your epoxy kit to mix the resin and hardener. Some kits may also include colorants to match the color of your shower pan.

Apply the epoxy mixture to the damaged area, making sure to fill it completely. Don't worry about making it smooth at this stage, as you will sand it later. Allow the epoxy to set for 2-3 hours, or longer for larger repairs.

Once the epoxy has set, use sandpaper to smooth out the surface. This step may require some elbow grease to get a seamless finish. Finally, use a finishing polish to blend the repaired area with the rest of the shower pan.

While repairing minor damage with an epoxy kit is a relatively easy process, it is important to follow the manufacturer's instructions carefully and take the necessary safety precautions, especially when working with epoxy, as it emits strong fumes.

Repairing large cracks and chips

If the large crack was caused by something being dropped in the shower, you can repair it yourself. First, clean the area with a household cleaner and a sponge. Use a solvent like rubbing alcohol, acetone, or something similar to remove oils, soap scum, and glass fibres. Then, drill six to eight small holes around the crack and inject two-component foam to create a strong foundation.

Next, apply a patch. If using fiberglass mesh, lay it over the crack to measure, then trim so that it is slightly larger than the crack. You may need more than one layer for deep holes. Mix the resin putty and hardener from your repair kit, adding colourant if necessary, and spread the mixture onto the patch. Allow the mixture to set for two to three hours or longer, depending on the depth of the crack.

Once set, use sandpaper to smooth the surface. This may take some time and effort. Finally, use finishing polish to help the patched area blend in with the rest of the shower pan.

Refinishing a plastic shower base

A plastic shower base can become discoloured over time due to footprints, soap scum, body oils, and dirt. While the surface may look clean, the discolouration can be an eyesore for those using the shower. Refinishing a shower base is a great way to restore and clean the shower's floor surface. The job requires less than half a day's work and can greatly improve a bathroom's overall aesthetics.

Step 1: Clean the shower base

Start by removing any old caulking surrounding the shower pan with a flat-head screwdriver. Then, use a sharp razor scraper to remove layers of caked-on soap scum from all the smooth parts of the shower pan, including the curb. Avoid scraping any textured portions.

Next, mix 1/2 cup of trisodium phosphate (TSP) with a gallon of warm water. TSP is a powerful cleaning agent, so be sure to wear rubber gloves and work in a well-ventilated area. Wash the shower base thoroughly with the mixture, then rinse well.

Step 2: Patch holes and cracks (if necessary)

If your shower pan has large cracks or holes, you'll need to address these before refinishing. First, make a series of holes around the damaged area using a drill and a 3/8-inch drill bit. Spray high-density foam into each hole until it overflows. Once the foam has set, cut it flush to the shower base with a knife and make a small indentation to allow room for epoxy resin.

For small holes, use a fiberglass resin repair kit. Scuff the area around the crack with 220-grit wet/dry sandpaper, then mix the filler and hardener according to the kit instructions. Spread the filler onto the hole with the provided applicator or a plastic putty knife. Scrape off any excess and sand the repair flat once the resin has set.

For hairline cracks, drill a 3/8-inch stop hole at either end to prevent it from spreading. For larger holes, scuff the area around the hole with sandpaper, then apply epoxy to the perimeter. Lay a piece of fiberglass mesh cloth over the hole, flattening the edges of the cloth into the epoxy. Apply one or two more coats over the cloth and scrape the epoxy level. Sand the repair flat once the final coat has set.

Step 3: Tape off the floor and shower walls

Lay masking tape and paper on the floor in front of the shower base and on the shower walls directly above the base. Remove the shower drain strainer with a flat-head screwdriver.

Step 4: Scuff the entire shower base

Use 220-grit sandpaper to dull the finish of the shower base. Keep sanding until no shiny spots remain.

Step 5: Apply primer (if necessary)

If your refinishing kit includes a primer, apply it according to the directions. Most primers are clear liquids that can be applied with an abrasive cloth or a kitchen scrubbie. They dry quickly, so you can move on to painting immediately. Remember to wear a respirator and keep the area well-ventilated.

Step 6: Mix and apply the first coat of paint

Mix the paint and hardener according to the manufacturer's instructions. If desired, add a non-slip texture to the mixture. Apply the first coat of paint using the provided applicator, a foam brush, or a foam roller. Avoid using a conventional brush or roller to prevent brush strokes or roller marks from appearing in the dried paint.

Step 7: Apply a second coat of paint

Let the first coat dry for the recommended time, then lightly scuff the shower pan with 220-grit sandpaper. Wipe away the sanding dust with a damp cloth and apply a second coat of paint.

Step 8: Apply polish and buff (optional)

If you want a higher-gloss finish, rub auto wax onto the finished surface after the paint has fully cured. Avoid waxing the bottom of the pan to prevent creating a slipping hazard. Buff the waxed areas with an electric buffer to achieve a high gloss.

Tips for repairing a fiberglass shower:

• Use a basic epoxy kit to repair cracks, chips, or holes in a fiberglass shower.
• Assess the damage to determine the type of repair needed.
• Look for an all-inclusive kit that contains polyester resin/epoxy, a mixing tray and stick, sandpaper, and colourants.
• For large cracks or holes, you may need to purchase fiberglass mesh separately to reinforce the putty.
• Clean the area with a household cleaner and a sponge before beginning any repairs.
• If the damage is due to a lack of support, drill six to eight small holes in the tub and inject two-component foam to create extra support.
• Always follow the safety recommendations provided by the kit manufacturer.

Repairing a flexing or moving shower pan

Before repairing a flexing or moving shower pan, it is important to identify the cause of the issue. This could be due to incorrect installation, such as a lack of a mortar bed or uneven subflooring, or improper cleaning or usage, such as using chemicals known to deteriorate the material of the shower pan.

• Inspect the shower pan carefully: Look for any cracks, gaps, or deterioration in the material, as well as any damage where the drain meets the pan. This will help identify the cause of the issue and direct your repair efforts.
• Secure the shower pan to the studs: Use a stud finder to locate the wall studs and then use pan-head screws to firmly fasten the shower pan to the studs, especially around the drain area. This will stabilize the pan and prevent shifting or flexing.
• Refasten the drain fixture: If the shower drain is loose, remove the drain strainer and use silicone adhesive to firmly attach the drain fitting to the bottom of the shower pan. This will stabilize the connection point of the drain.
• Use construction adhesive under the pan: For fiberglass or acrylic shower pans, apply a bead of construction adhesive between the pan and the subfloor to bond the pan to the floor and prevent movement.
• Add braces under the pan: For flexing issues near the walls, add metal or wooden bracing material under the pan. Cut braces to fit tightly between the pan and joists or adjacent walls, and secure them with construction adhesive and screws.
• Replace rotted wood supports: If there is rotted or deteriorated wood underneath the shower pan, cut away the damaged wood and replace it with new 2x4 blocks and plywood patching using construction adhesive and wood screws.
• Consider replacing the shower pan: If the damage is extensive or there is flexing across large areas, it may be best to replace the shower pan. This can be a major project, but it may be the only way to permanently fix ongoing flexing issues.

To prevent future flexing issues, it is recommended to use a cement backer board under any new tile shower pan, securely attach the pan to studs with screws, seal all edges and seams with flexible caulk, slope the pan correctly towards the drain, and avoid stepping directly on the shower pan.

Repairing clear coat on a shower pan

To repair clear coat on a shower pan, you can use a refinishing kit that contains a two-part epoxy paint specially formulated for plastic shower pans. The kit will typically include epoxy, hardener, application tools, and cleaning supplies. You may also need to purchase a separate repair kit to patch any holes or cracks in the shower pan.

• Clean the shower base: Remove any soap scum or caulking using a sharp razor scraper. Then, clean the base with a mixture of trisodium phosphate (TSP) and warm water.
• Spray foam for support: If there are large cracks or holes due to insufficient support, drill a series of holes around the affected area and spray high-density foam into the holes until it overflows. Cut the foam flush with the shower base and make a small indentation for the epoxy resin.
• Repair cracks and holes: Use a fiberglass resin repair kit to fill small holes or cracks. Scuff the area with sandpaper, mix the filler and hardener, and spread it onto the affected area. For larger holes, apply epoxy to the perimeter and lay a piece of fiberglass mesh cloth over the hole before applying additional coats of epoxy.
• Tape off the floor and shower walls: Lay masking tape and paper on the floor and shower walls to protect them from paint.
• Scuff the entire shower base: Use sandpaper to dull the finish of the shower base, ensuring that no part of the base is shiny.
• Apply primer: If your refinishing kit includes a primer, apply it with an abrasive cloth or kitchen scrubbie according to the directions.
• Mix the paint according to the directions: Pour the hardener into the paint container and stir well. Add a nonslip texture if desired.
• Spread the first coat: Apply the paint with the provided applicator, a foam brush, or a foam roller. Avoid using a conventional brush or roller to prevent brush strokes or roller marks.
• Scuff and apply a second coat: After the first coat has dried, lightly scuff the shower pan with sandpaper and wipe away the dust with a damp cloth. Then, apply a second coat of paint.
• Apply polish and buff (optional): If you want a higher-gloss finish, rub auto wax on the finished surface and buff it with an electric buffer.
