The pool coating is, of course, what will cover the walls and the bottom and ensure the finish of the basin. It has a great importance.  We will see further that it must mainly be chosen in accordance with the swimming pool structure.

There are two kinds of swimming pool coverings: those that are waterproof by themselves and others. So it is essential to know them to make the right choice of construction mode.

Waterproof swimming pool coating

The liner, the reinforced PVC membrane, the polyester reinforced with fibreglass fall into this category. The first two are very well known and widely used. The latter is less prevalent due to its significantly higher price. They ensure both the finish and the sealing of the pool.

The main advantage of these coatings is that they can be laid on any pool structure, even not waterproof: cement blocks, Hollow blocks with reinforced concrete or traditional shuttered concrete. For swimming pools in wood, aluminium or polystyrene,the liner is widely used. Any customer can lay it easily.

The Liner is a flexible PVC or vinyl membrane. It consists of a single piece made in the factory based on the exact dimensions of the pool. The colour palette is increasingly large, but the preferred shades remain blue, beige, turquoise and sometimes light grey.

The PVC membrane is sometimes confused with the liner, but it is very different. It consists of 2 sheets of PVC between which is placed a polyester frame. It is therefore thicker than the liner, but also more resistant. The welding is carried out directly in the basin and requires the intervention of a professional. They are proposed in an extensive variety of colours.

The Fibreglass Reinforced polyester is also known as laminated polyester. It consists of an overlay of layers of polyester resin and fiberglass mats. A finished layer called gel coat is then applied. The colour palette is very wide. This coating clearly recalls the boat hull coverings. The application is done on the spot by professionals.

Another coating of the family of Marble– Plastering is now in increasingly used.  It is composed of cement, marble dust and additives. Like all coatings and unlike membranes, it totally adheres to the support: see further the disadvantages of this sort of coating. Although it is waterproof, is is recommended to use it only for concrete basins: Hollow blocks filled with reinforced concrete or traditional shuttered concrete.

And what about the one not waterproof?

This must be laid on a solid structure and already sealed by the application of a specific coating, based on epoxy resin for example.

The Tile is undoubtedly the most used coating in the world; In many countries, it is the only one. There is a multitude of both in terms of form and colours.

  • The mosaics, also known as crystal glass, are small tiles of 20 × 20 mm or 15 × 15 mm pre-assembled on PVC grates of about 30 cm x 30 cm. The tiling is easy and there are a multitude of shades. On the skimmer pools, maching border tiles can be added at the water line level.
  • Ceramics are varnished tiles whose price remains reasonable. The colour range  is small, but the variety of sizes is great.
  • Glazes comparable to crystal glass mosaics, but covered with an email layer have a remarkable satin effect, but their price is the highest. As with glass pasta there are models with colour mixing.

And why not be lured by the Natural Stone. It is, in fact, not reserved for the edge of the pool and can also be placed in the basin. Thanks to new processes, it is now possible to find stones glued to a composite medium with a thickness of ± 2 mm. And remember that there are stones coming from exotic lands; They even turn the pool into more mundane.

The painting is used less and less for the swimming pools coating. It is, now, replaced by the liner.

Go for a adherent or non-adherent swimming pool coating

Some such as the liner, the reinforced PVC membrane or the reinforced polyester with fibreglass are said to be non-adherent or semi adherent to the support. Others, such as tile or marble –plastering coating, tile or stones are fully bonding to the masonry. In this case, if the structure cracks the coating will crack too. Therefore, it is absolutely unwise to use a fully bonding coating on a light structure.

How to choose a pool lining ?

The choice depends on several criteria such as :

  • The budget: If we talk about a tight budget, we will undoubtedly head towards the liner which is the cheapest solution. In the case of a concrete structure, you will be able to opt for the tile which allows to make beautiful things with a limited budget.
  • The structure of the pool: the liner, the PVC membrane or the polyester reinforced with fibreglass can be laid in any swimming pool. For marble-plastering coating, tile or stone must be used in concrete swimming pools only.
  • The shape of the pool: the liner is preferred for rectangular shapes. Made in factory, it is often difficult to install it on other forms. For free shapes, the best option is, without a doubt, the polyester with fibreglass or the marble-plastering coating.
  • Aesthetics: Since this is a matter of personal taste, we can only say that the enamels, the natural stone, the marble-plastering coating and the polyester reinforced with fibreglass are the most beautiful.
