Description
The article discusses the different types of fibreglass swimming pool linings, their main components, and how to apply them. It also provides instructions for using a top coat to seal the fibreglass mat and protect it from water.
Top coat is used in the final coat of paint to seal and protect the underlying fibreglass mat from water.
The easiest colour to work with is white top coat and that is what we will recommend from a practical point of view. White top coat do not change colour or fade as much as all other colours do.
Fibreglass lining pools are typically build-up of multiple layers - a resin coat on the concrete or fibreglass surface that act as primer, then an interior barrier layer of fibre matt followed by resin and surface tissue paper; and another coat of resin to give the lining structural strength. The final coat or Top Coat seals the fibreglass pool lining and act as a interior water-tight barrier.
Important:
Surfaces should always be dry before application of Top Coats and kept dry for at least 8 hours from application
If it rains, dry and keep dry as much as possible
Allow Top Coats in swimming pools to stand without water for at least 7 days to cure properly before filling
Do not apply Top Coat in air temperatures below 17 Degrees Celsius or above 30 Degrees Celsius to ensure optimum results. Extreme temperatures will cause too slow or too fast curing of Top Coats and resins.
Add Catalyst Hardner to the Top Coat in a ratio of 1% (hot weather) to 3% (cold weather) per volume, that is between 10ml and 30ml per kiligram of product
Remember the more Catalyst you add, the faster hardning takes place and the potlife (paint time) decreases.
Do not add less than 1% Catalyst and not more than 3% Catalyst because it may weaken the final product
We suggest that you mix the Top Coat in batches of not more than 5 kg at a time

The 6 main components of fibreglass swimming pool linings are:
FIBREGLASS MATT that gives structure and strength to the pool lining
FIBREGLASS SURFACE TISSUE and/or printed MOSAIC TISSUE SHEETS (Optional) to mark the waterline and steps of swimming pools
POOL RESIN is used to laminate fibreglass matt and surface tissue together to form a watertight lining
FIBREGLASS TOP COAT: SKYBLUE or WHITE TOP COAT is used as final coat for the entire interior surface of a pool to protect the fibreglass matt against water, while CLEAR TOP COAT is used as laminating and protective paint on areas where MOSAIC TISSUE SHEETS / MOTIFS are placed
FIBREGLASS PUTTY POWDER (DE) are mixed with resin and catalyst to form a putty to fill holes and uneven areas
FIBREGLASS CATALYST HARDENER that is mixed in a small quantity with TOP COATS & RESINS
Fibreglass linings are applied to smooth plastered concrete or old marblite swimming pool linings to make it water-tight.
Acetone is used for cleaning paint brushes, rollers etc.
WARNING:
Always work in a well ventilated areas with fibreglass and related materials
Wear protective clothing; eye protection and mask (respirator)
