Choose the Best Swimming Pool Coating for Your Pool Type
Swimming pool coating increases durability, hygiene & safety
The damp environment of a swimming pool provides an increased risk of legionella and other waterborne bacteria. Fortunately, this risk can be minimized by swimming pool coating; it seals surfaces and provides a smooth finish to which dirt and other contamination cannot attach. As well as their hygienic function, pool coatings also create a durable protective layer which reduces the need for maintenance and guarantees a safe visit to the pool.
The 4 benefits of swimming pool coating
- Seamless finish: No sharp edges, cracks or seams which might cause injuries.
- Prevents leakages: Swimming pool paint is waterproof. The subsurface pool therefore, remains dry and will not be damaged by prolonged exposure to water.
- Aesthetics: That beautiful fresh ocean blue? Or an industrial concrete look? Pool paint is available in many colours, finishes and textures.
- Ensures invisible hygiene: Due to the seamless structure of the coating, no contamination can attach to the surface.

Learn which swimming pool coating is suitable for your pool type
Not every pool coating can be applied to any surface. For example, coatings that are especially suitable for porous substrates such as concrete are not suitable for baths made of fibreglass because of different requirements for adhesion. It is also important to define the expected looks of the finished pool: do you wish to protect the surface without changing its appearance, or is the purpose to give the pool a makeover while making it safer and more hygienic?
Whatever the case, here are some general guidelines to which coatings are suitable for your pool type and material.
Aluminium or stainless steel pools and baths
Suitable coating: Anti corrosive acrylic polyurethane
For stainless steel and aluminium baths it is important to opt for a coating with an anti corrosive effect, or a rust-inhibiting primer. Always consult a specialist before choosing a swimming pool paint to prevent any issues related to adhesion or premature corrosion and further deterioration.
Suitable coating: 1 component epoxy paint (private pools), epoxy coating and polyurea coating
Epoxy coating adheres well to fibreglass and is extremely resistant to chemicals (chlorine and detergents). The disadvantage is that the application and curing of epoxy is a relatively long process: 3-7 days depending on the layer thickness. Polyurea coating, however, is applied with high-pressure spray equipment and dries much faster. For small fibreglass pools or local repairs, one component epoxy-based paints are also available.
Tile swimming pools
Suitable coating: Primer + Epoxy coating (indoor pools), Polyurea hot spray (commercial pools) or chlorinated rubber pool paint (private baths)
Almost all two component coatings are suitable for applying over tiles, as long as a good primer is used. If you wish to retain the pool’s looks, you should choose epoxy because it is the only option that can be applied as a transparent layer. However, it can crack as a result of temperature fluctuation and UV radiation when applied to an outdoor pool. Epoxy can also be opaque, however multiple layers are required if you wish to hide the tile structure and seams. Chlorinated rubber is the cheapest option, but it comes in a limited range of colours and is not recommended for commercial baths due to its poor resistance to oils.
Suitable coating: Primer + Polyurethane coating (commercial pools), chlorinated rubber pool paint (private baths) or epoxy coating (indoor pools)
A concrete pool almost always requires a primer; the top coat can be epoxy, chlorinated rubber, or polyurethane based. Epoxy pool paint is not recommended for new pools due to its lack of flexibility; new concrete may “live” requiring the coating to stretch with it. Polyurethane is more flexible and can better absorb small cracks. Chlorinated rubber systems provide a fully watertight swimming pool as well as being resistant to chlorine and preventing algal growth. The disadvantage of chlorinated rubber is its poor resistance to fats and oils (including sunscreen), so it should not be the first choice for commercial outdoor swimming pools.
Other surfaces that benefit from swimming pool paint
In addition to actual swimming pools, other areas such as wellness facilities and saunas can also benefit from a watertight swimming pool coating which can also be made slip resistant to prevent slips and trips. Swimming pool paint makes pools durable and hygienic, and also does this for the areas around the pool. For example the following areas may benefit from pool paints.
- Walk-through rooms of saunas
- Saunas, steam baths, changing rooms and shower rooms in gyms
- Bungalow parks and campsites with swimming and/or wellness facilities
- Joint shower rooms of gyms
- Walk-in showers
- Changing rooms of spas and pools
- In and around water attractions (eg slides or children’s pools)
A high-quality swimming pool coating ensures that both the recreational swimmer and sauna visitor can safely enjoy the swimming pool and the area around it.
What defines the price of swimming pool coating job
Pool coating specialists often produce a quotation based on 5 factors. Therefore, you should take the following into account:
- The results of the inspection: Moisture in the subsoil, potholes and bumps, difficult to access spaces; these are all matters that must be taken into account before application. The fewer pitfalls and obstacles there are, the lower the quotation price.
- The preparation required: One of the most important steps for application. A good surface ensures that the coating adheres optimally. Are there a lot of repair and equalisation works required in advance? Or a thorough cleaning? Or maybe a primer? These costs come on top of the coating.
- Application method: Some surfaces are ideal for application with a roller/brush, others require application with high-pressure spray equipment. Sometimes one layer is sufficient, but often several layers are needed. This all affects the price calculation.
- Finishing wishes: Do you want a specific colour or special effect? There is a lot possible in terms of finish, including details like the lane lines and markings in competition pools. Of course there is a price tag.
- Extra options: Often the coating is not only applied in the swimming pool, but also around it. Think of the foot baths, pool edges or shower rooms. Here you can opt for an anti-slip finish at an additional cost.
