Avoid Using Harsh Chemicals

When maintaining a repaired fiberglass tub, avoid using strong chemicals like bleach or ammonia-based cleaners. These substances can break down the resin in fiberglass putty for tubs, weakening the repair and reducing its lifespan. Stick to mild, non-toxic cleaning solutions to keep the surface intact.

By following these best practices and using appropriate cleaning techniques, you can ensure that your fiberglass putty for tubs repair lasts for years while keeping your tub looking clean and smooth. Regular care and attention to detail will help maintain both the aesthetics and functionality of the tub.

Common Mistakes to Avoid When Using Fiberglass Putty for Tubs

Common Errors When Using Fiberglass Putty for Tubs

Using fiberglass putty for tubs can be an effective way to repair cracks, but DIYers often make avoidable mistakes that compromise the quality of the repair.
