Part 1: Introduction to Fiberglass and Its Repair Potential
Fiberglass is widely used because it’s durable and corrosion resistant. For example, it’s popular in swimming pools, boats, roofing, and construction. Despite its longevity, fibreglass is not invincible.
Can fibreglass be repaired? Absolutely! From minor cracks to major damage, modern materials like epoxy resin and fibreglass cloth make repairs effective and affordable.
What is Fiberglass?
Fiberglass consists of glass fibres embedded in resin. It is lightweight, waterproof, and mouldable into complex shapes. Common uses include:
- Swimming pool shells
- Boat hulls
- Car body panels
- Structural roofing
Why Does Fiberglass Crack or Fail?
Several factors cause fibreglass to deteriorate:
- UV damage over time
- Soil movement beneath pools
- Impact or mechanical stress
- Poor installation or resin curing
Can Old Fiberglass Be Restored?
Yes. Through resurfacing or relining (especially for pools), fibreglass can look like new again. This process involves:
- Sanding down the surface
- Applying new fibreglass cloth and resin
- Finishing with a gelcoat or top layer
When to Repair vs Replace?
- Repair if damage is localised or cosmetic (typically between R500 and R5,000)
- Replace or reline if the entire surface is degraded or blistered (costs R20,000+)
