GFC: The ideal solution for commercial spa resurfacing
This commercial pool operator at a major casino in Las Vegas had ongoing problems with spa surfaces requiring periodic resurfacing using cement-based materials. Common problems in spas are black algae infestation, and severe staining and rough surfaces making for a very uncomfortable bathing experience.
Due to the high temperatures and bather load, the owner was searching for a product which would not require expensive periodic resurfacing and offered excellent esthetic retention. Candidate coatings were evaluated to determine which one had the best lifecycle cost and performance. Vinyl liners, high-performance novolac epoxy, and GFCs were assessed.
Once again, the evaluation showed that GFC would outperform the competing materials in all criteria under examination. High-performance BPA EVER was used to withstand the high water temperature, and offer superior blister resistance, as EVER are well-known for holding up to the abuse in hot commercial spas. The owner was impressed with the outcome, as the GFC enhanced the esthetic and created a clean, inviting look.
How the market is shaping innovation
The pool coatings market has stagnated over the years, and no new products have come to market. The introduction of GFCs has changed this. Foundationally, end users desire faster cures, easier application, reduced number of layers, and longer service periods for coating solutions. GFCs simplify the overall process, and provide outstanding performance, productivity, and esthetics retention.
GFCs are a versatile pool coating system because they can be applied to all metals and concrete. The rise of pre-manufactured steel pools for elevated structures, such as hotels and condominiums, make GFCs the ideal finish thanks to its waterproofing properties. Elevated pools are logistically more difficult to work on because of access, so owners want a product that does not require frequent reapplication or disruption to guest services. These coatings are also extremely lightweight compared to cement-based finishes.
Coating characteristics to consider
As a guide, here are some characteristics to consider before selecting a pool coating.
- Weight of coating product. This is of special importance when renovating elevated pools. Polymeric materials are much lighter and stronger than cement-base products.
- Durability, versatility, and potential service life.
- How inert, waterproof, and corrosion-resistant is the material.
- Is the product relatively immune to the damaging effects of pool water and chlorine?
- How forgiving is the coating to out-of-balance water chemistry and pH swings?
- How tolerant is the coating of hot water
in spas?
