1. Initial Preparation

Before the fibreglass can be applied, the pool surface needs to be prepared. The prep work depends on the type and condition of the pool, but can include coving, plastering, structural repairs or changes to fittings.

2. Spray Preparation

The pool is masked out and shaded by a canvas cover. Debris is cleared and the spray equipment is set up.

3. Lamination

The fibreglass used for spraying is a strand, unlike the mat or weave used for hand-laying. The strand is cut into short fibres and mixed with a thermosetting polymer resin and catalyst via the chopper gun. Ample thickness is applied to provide long lasting strength.

After the fibreglass has set, any imperfections in the surface are identified and removed.

4. Gelcoat

Pigmented gelcoat is catalysed and applied through the spray gun to create a glossy surface coat. This waxy material is polyester-based and forms crosslink bonds with the laminate, adding to its durability. Coverage is thorough and consistent.

5. Finishing

Although dependent on weather conditions, the canvas cover and the majority of the masking are often removed within hours of the spray. The pool is generally left overnight before trimming the edges and reinstalling fittings. Any other finishing work is typically completed at this time.

6. Cure

Depending on weather and temperature, the pool may be left empty for up to a few days. This is to ensure the curing process is complete and prevent an undercure, which can create surface blisters.

After a satisfactory cure is achieved, the pool can be filled and enjoyed!
