Having a school swimming pool is both a great resource and a big responsibility.

There are many issues to deal with including:

  • Hygiene
  • Safety
  • Coating Maintenance

In this article we aim to quickly deal with issues covering the most cost effective coating maintenance of the pool and its environs. Those issues relating to safety and hygiene we would refer to other more appropriate organisations.

Asset maintenance

A swimming pool is a major asset and as such requires careful and thoughtful analysis. This is to ensure maximum performance and value for the pool coating.

The ideal situation is where the pool has a coating that has:

  • Easy clean surface
  • Smooth, non abrasive finish
  • Attractive colour
  • Long lasting performance
  • Hard wearing surface
  • Easy to refurbish

The ideal answer is to have the longest life with the minimum downtime and need for recoating.

The paint systems

  • There are 3 types of paint systems in us for swimming pools.

The key facts on a complicated subject are:

  • PVA's, Paving Paints, Acrylic's – poor performance
  • Chlorinated Rubbers, Vinyls, Polyurethanes, – acceptable performance.
  • Epoxies: (two pack) – excellent performance.
  • Chlorinated Rubbers, Vinyls & Polyurethanes are readily available and generally used on smaller pools, farm troughs and storage tanks.
  • Epoxy, (two pack), has the best performance, least problems and best value.

Why Chlorinated Rubber?

When you select a Chlorinated Rubber you will use a solvent based, one pack paint. The material has been used extensively in swimming pools. It offers good chemical resistant and reasonable performance. It will last on average 2 – 3 years.

Why Epoxy?

When you select a 2 pack epoxy for your pool, you will get: a high molecular weight, cross linked, chemically resistant, 3 dimensional structure.

This means it is tough, bonds well and is durable. It will last 7 – 10 years plus.

With any coating, the performance of it will depend principally on:

  • Correct surface preparation, before application
  • Correct application of coating
  • Correct curing/drying of coating

No matter which coating is to be applied, the surface preparation for existing pools will be the dominant factor for hassle free performance, in our lengthy experience. For new pools, it is still important, though application takes on a bigger roll.

Any contractor who does not understand these issues, or does not follow well established procedures, will leave a brewing problem for your school to deal with.
