Pool Resurfacing Techniques – Comparative Analysis of Plaster and Glasscoat

POOL RESURFACING TECHNIQUES -COMPARATIVE ANALYSIS OF PLASTER & GLASSCOAT

PLASTER

POOL CONDITIONS

GLASSCOAT

As plaster wears, roughness
increases. Quartz and pebble
plaster becomes rough with age.

ROUGH SURFACES

Glasscoat is always smooth.
No scratched feet.

Any substantial pool movement
can cause cracks and leaks.

STRUCTURAL CRACKS

Adds structural strength to pool shell. Prevents leaking.

Little resistance to stains and blemishes, even if surface has been recently applied.

BLEMISHES AND STAINS

Glasscoat has a resistance to stains, with easily cleaned surface.

Algae adheres to porous surfaces

ALGAE RESISTANCE

Smooth, dense, non-porous surface prevents algae from adhering.

High chemical requirement at all times. Reactive surface.

CHEMICAL DEMAND

Noticeable reduction in chemical usage due to the inert nature of GLASSCOAT. Makes pool chemicals more efficient.

Unsightly when stained/deteriorated.

ATTRACTIVENESS

Maintains attractive appearance.

Depends on application. Replaster often separates from original surface (poor adhesion). Material limitations reduce the durability of plaster.

DURABILITY

The superior corrosion resistant and inert properties of GLASSCOAT ensure exceptional durability.

Very sensitive to incorrect water chemistry. Plaster surface easily compromised.

WATER CHEMISTRY

Inert surface less sensitive to out-of-balance water chemistry – a very forgiving surface.

Because of material limitations, very limited warranty offered (workmanship only).

WARRANTY

Applied by specialists. More comprehensive warranty offered.

Varies and depends on water chemistry, maintenance regime, plaster mix and application technique. Average is 5–7 years.

LIFE EXPECTANCY

Far exceeds service life of plaster. Time tested with 30 years industry experience.

Complicated. Requires brushing and attention.

START-UP

Simple. No brushing needed. Allow to cure, then start-up.
