Fiberglass tubs and showers are common in many modern homes but over time, they can become damaged. Knowing the basics on how to repair the smaller cracks, dings and dents yourself is a good skill to have and can often save you money. A repair kit and a few simple items are all you need to repair your tub.
Things You'll Need
- Fiberglass tub repair kit
- Plastic spatula or cardboard
- Dust Mask
- Paintbrush or sprayer
- Soft cloth
Sand the damaged area of the tub with a rough sandpaper to prepare the area. After sanding, if you find that the crack or gouge is substantial, consider gaining access to underneath the tub and reinforcing it from the bottom and/or filling the crack/hole with an epoxy-based patch material before continuing to prevent future leaks.
Cut as many pieces of fiberglass mesh as you will need to fill the damaged area to the size suggested by the kit maker. While wearing gloves and respiration mask, mix the resin and hardener compounds. Use either a piece of cardboard or plastic spatula to spread the filler onto the prepared area. Or, carefully immerse the fiberglass mesh into the resin mixture before applying it to the area, layering as directed by the instructions. Let the area cure thoroughly.
Sand the repaired area using progressively finer grades of sandpaper. Wear a mask while sanding. Fiberglass can be a difficult product to sand, so take your time and do not rush the process. When the area is sanded to your liking, test a small amount of the paint in an inconspicuous area of the tub to check for color compatibility. Let the paint dry completely. If the color does not match your tub, refer to the manufacturer's instructions on how to tint the paint.
Apply the paint either with a brush or sprayer. Don't worry too much about overspray or painting other parts of the tub; the paint will not usually stick to the unsanded portion of the tub. Allow at least 24 hours for the paint to dry. Polish the area with a soft rag to bring out the paint's luster, then clean the tub before use.
Tips & Warnings
- Avoid breathing in the compounds and avoid getting them on your skin. Use chemicals in a very well-ventilated area. Keep children and pets out of the area. Dispose of any leftover compounds and chemicals safely.
