How to set up a saline chlorinated pool

Salt chlorination has been gaining importance in recent years as a solution increasingly used in swimming pools to minimise their maintenance during the summer. Therefore, from Molins, we would like to share some recommendations on how to set up a salt chlorination pool.

The advantage of salt chlorination is that, by reducing the use of chemicals, you save money and at the same time enjoy clearer, healthier and more environmentally friendly water.

However, unlike traditional chlorination, saline chlorination requires special attention to the sealing of the joints, as this component is very aggressive and can attack materials made of cement, which means that they need to be repaired almost every year. However, a proper rehabilitation can make it unnecessary to worry about its revision for the next 10 years.

Step by step

First of all, experts recommend that the pool should be prepared a few weeks before it is filled, so that we have enough time to carry out the relevant renovations and arrive at the summer with the pool in perfect condition, ensuring that it remains in perfect condition throughout the season.

To avoid unnecessary waste of water due to leaks and filtrations – which can amount to up to 500 litres per day, equivalent to the approximate average consumption of a family of four – it is important to check the waterproofing under tiles and the proper sealing of critical points such as impellers, spotlights and skimmers (the filters that suck in and retain waste) to ensure they are watertight.

These leaks can empty the pool within a month, which is why specialists recommend waterproofing with continuous flexible cementitious solutions (such as Propam® Impe Flex), which are compatible with all building materials and guarantee a waterproofing that can be coated with any material, be it paint or ceramic tiles such as gresite.

Once the watertightness has been checked, it is time to apply the finish and, if necessary, seal the joints of the pool tiles with saline chlorination. To avoid having to wait every season, there are more resistant sealing solutions that are easy to apply and clean (such as Borada Epoluxe) specifically designed for contact with saline water and any type of maintenance, however frequent and aggressive it may be.

The complete and successful renovation of the pool, whether salt chlorination is chosen or not, is a relatively short process. However, depending on the size of the pool and the materials used, it can take between two weeks and a month to complete, hence the importance of planning ahead”.
