Can I Fix A Crack In My Spa/Bathtub or Jacuzzi?
The good news? Yes. Cracks in spas or bathtubs can be fixed.
But first, let’s understand what a crack is. Spas, bathrubs & jacuzzis are subject to both cracks and crazing. A crack is a well-defined, easily seen separation of the surface. It can be a single crack or have a few branches. Whereas, crazing consists of hundreds of small, often difficult to see without magnification, covering a larger area. Cracks and crazing have different causes, and crazing is more difficult to repair.
Cracks can occur due to mechanical impact or from excessive stress in the surface, which becomes higher than the material strength. Multiple causes of excessive stress exist. These are exaggerated when the surface gets hot due to sunlight, etc. There can be multiple cracks in a surface, and they go through the entire surface layer.
However, crazing is generally caused from a chemical attack. The chemical attack can be from the visible surface side, or the underside. Crazing from the underside has been predominately caused by excess styrene in the fiberglass reinforcement. Numerous chemicals have been known to cause cracks and crazing from the visible surface. These are normally caused by the owner or pool Jacuzzi maintenance companies.
Cracks in acrylic or gelcoat spas, bathtubs or showers can be repaired by calling All American Refinishing, Inc., who specializes in bathtub repair, for small or major repairs.
Many bathrooms contain a combination, one piece shower and tub. These are generally made from fiberglass reinforced plastic (FRP) coated with a gelcoat resin. They can develop cracks in the tub bottom caused by inadequate support to withstand the weight of the users. Repair of these cracks requires adding reinforcement to the underlying support structure.
All American Refinishing also has products and procedures for this operation.
