Items you will need for repairing an acrylic bath crack

Before you begin repairing an acrylic bath, make sure you have all the following items:

  • 400-grit sandpaper
  • Auto polish urethane compound
  • Bathtub repair paint
  • Buffer
  • Denatured alcohol
  • Drill and 0.25-inch bit
  • Insulating foam
  • Portable sprayer
  • Rubber filler spreader
  • Two-part polyester filler

Repairing an Acrylic Bath: Step-by-Step

Here are easy step-by-step instructions for repairing an acrylic bath that has a crack in the tub:

1. Stabilize the cavities of the acrylic bath

The first step of repairing an acrylic bath is to make sure that no future cracks start from where the first one appeared in the tub. To do so, drill 0.25-inch holes around the crack, making sure you don’t drill through the exterior surface of the bathtub. Then apply insulating foam on the holes and wait for it to dry before proceeding.

2. Stop drill the crack

The other risk with a crack is that, after you repair it, it reappears along the length of the original crack. You can prevent this by using a similar procedure to that of step number one at both ends of the crack. Following the direction of the crack, you should drill two 0.25-inch holes, except these holes shouldn’t be injected with insulating foam.

3. Fill the crack

The third step of repairing an acrylic bath is to fill the crack. After you have stabilized the entire region—thus making sure that the crack won’t reappear in the future—you can fill the crack. Apply a 2-part polyester filler to the crack and to the two 0.25-inch holes on both ends of the crack until they are completely filled. Let it dry before proceeding.

4. Use sandpaper

Once the filler is dry, you can use a light sandpaper until the surface is even. Make sure you rub gently using sandpapers between P800 and P320. When you’re done, apply denatured alcohol and proceed for painting.

5. Spray paint the repair

Once you sand the surface of the tub, the next step in repairing an acrylic tub is to spray paint the repair. To apply the paint, you’ll need a portable sprayer. Mix the paint and apply several light coats, until the color is even and matches that of the bathtub.

6. Apply auto polish

The repair part is done, but you can accomplish a greater result by applying an auto polish urethane compound. This will help the colors blend better and give your handiwork the perfect finishing touch.
