Fixing Fiberglass Tub Crack The Best Guide 2022

Today let’s check our fixing fiberglass tub crack guide. Fiberglass tubs can develop stress, hairline, and spider cracks from frequent use, inadequate support, harsh cleaners, and heavy objects hitting the tub and dropping it. These small cracks can become larger cracks, which can lead to leaks and ultimately the bathtub breaking apart. Luckily, you can fix hairline cracks on fiberglass tubs quite easily.

Dry the crack and then sand it using fine-grit sandpaper. Use a fiberglass filler and an adhesive to seal the crack. The epoxy mixture should be applied to the crack. Next, sand the area. To fix a fiberglass tub’s hairline crack, apply more epoxy and sealer.

Fixing Fiberglass Tub Crack The Best Guide 2022

Fiberglass is a stronger and more durable option than traditional ceramic and metal showers and tubs. Unsightly cracks can form in tubs that are not supported or have been subjected to abuse and heavy use. If left untreated, these cracks may become deeper or larger holes in the walls and floor of your tub. These cracks can be fixed with a basic fiberglass repair kit.

Here are some steps to repair cracks in fiberglass tubs:

1. Use a sponge or rag to apply the household cleaner to the crack. Rinse the area with water, then dry it with a towel or rag.

2. Use fine-grit sandpaper to lightly sand the area around the hairline crack. Use a rag to remove any sanding dust.

3. Use the fiberglass adhesive or bonding agent included in your kit to fill the crack. You can use the included brush or a smaller paintbrush. You should cover the crack and leave a 1-inch gap around the area that is damaged. Before proceeding, let the bonding agent dry according to the package repair kit instructions.

4. Fill the crack with fiberglass glue. Use a putty knife to apply the fiberglass filler. Next, scrape the tub’s surface and surrounding tub surface with the knife in order to remove any excess putty. Before you proceed with the repair, allow the putty to dry completely.

5. Use fine-grit sandpaper to sand the patched areas. Continue to sand until the patched area is flush with the tub’s surface. Use a sponge or rag to remove the sanding dust.

6. Mix the epoxy gel coating from your repair kit.

7. Apply the gel coat using a paintbrush to patch the area. You can paint the crack and a 2-inch surrounding area.

8. To fit the area of paint, cut a piece from fiberglass cloth. Use your hands to press the cloth into the epoxy gel coat. Use your fingers to smoothen the fiberglass cloth against the tub wall.

9. Apply the epoxy gel coat to the fiberglass cloth again.

10. Use a paintbrush to apply the sealer or finish coat that was included with your repair kit.
