I. Nature of the problem – requirements

A common and cost-effective way to prepare the final surface of the pool is to paint it with a special paint such as an epoxy coating. This is an efficient technical solution that is clearly more economical than covering with ceramic tiles.

The choice to use an epoxy coating significantly affects the choice of a means of waterproofing the pool, because it determines the specific requirements for the waterproofing that is carried out.

In particular, the waterproofing layer should:

• to have high durability, because its position between the structural elements of the pool and the epoxy coating layer makes future interventions difficult and costly.
• Adhere well to the structural elements of the pool to withstand the negative pressure that may occur periodically.
• Have a smooth surface.

The coating used must have the following characteristics:

• Elasticity, in order not to crack from possible expansions and contractions.
• Resistance to water and chemicals that may be present in pool water (e.g. chlorine).
• Resistance to weather effects (such as solar radiation, frost, etc.).

solution

The primary condition is that the pool frame must be properly calculated to successfully withstand the hydrostatic pressure of the water.

The waterproofing of the pool is effectively achieved by using water-resistant cement mortar on the walls and floor of the pool, which simultaneously acts as a sealing and smoothing layer. Thus, the smooth, stable and waterproof substrate required for applying the epoxy coating is created.

This cement mortar becomes waterproof by adding ΑDINOL-DM waterproof additive to the ratio of 1% of cement weight.

Application

Preparation of the substrate

1. The substrate must be thoroughly cleaned of grease residues, fillers, loose materials, dust, etc.
2. Excessive construction forks should be cut to the level of the wall.
3. A strong and waterproof bottom layer of cement mortar (cement: Sand = 1: 2.5) It should be prepared by adding ADINOL-DM waterproof mixture at a rate of 1% of cement weight.
   Connecting cement mortar to vertical surfaces using a sprayer with the addition of ADIPLAST polymer latex (cement: Sand: ADIPLAST: Water = 1: 1: 0.25: 0.25 parts by volume) is strengthened.
   Connecting the cement mortar to the pool floor by applying a bonding layer with the addition of ADIPLAST (cement: Sand: ADIPLAST : Water = 1: 1 : 0,5 : 0.5 parts by volume) is strengthened.
   The bottom layer should be implemented with the help of guide beams with a thickness of 2-3 cm.
   Use of ADINOL-DM: About. ^{4.2 kg/m3} of cement mortar
4. A strong and waterproof finishing layer of cement mortar should be made using fine-grained sand (cement: Sand = 1: 2) to which ADINOL-DM waterproofing additive is added at the rate of 1% of cement. Weight.
   The cement mortar should be applied in a thickness of 5-10 mm and then applied with a sponge float.
   Use of ADINOL-DM: About ^{5 kg/m3} of cement mortar.
5. At the intersection of the walls and the pool floor and where the walls meet, it is recommended to create a groove during the application of cement mortar to facilitate the subsequent application of epoxy products.

Primer and painting with EPOXYCOAT-S epoxy paint

1. At least 28 days after applying the cement mortar, the time required for it to harden and until it is dry (moisture less than 4%), the surface of the pool floor and wall should be lined with DUROFLOOR-BΙ.
   Components A (resin) and B (hardener) are packaged in two separate containers and have the correct predetermined mixing ratio by weight. The total value of component B is added to component A. Mixing the 2 components should be done for about 5 minutes using a low speed mixer (300 rpm). To succeed in evenly dispersing the hardener, it is important to stir the mixture thoroughly near the sides and bottom of the container.
2. Any cracks or defects must be filled with EPOMAX-EK epoxy putty.
3. After the primer has dried and within 24 hours of implementation, the pool must be painted with EPOXYCOAT-S epoxy coating.
   Components A (resin) and B (hardener) are packaged in two separate containers and have the correct predetermined mixing ratio by weight. The total value of component B is added to component A. Mixing the 2 components should be done for about 5 minutes using a low speed mixer (300 rpm). To succeed in evenly dispersing the hardener, it is important to stir the mixture thoroughly near the sides and bottom of the container.
   EPOXYCOAT-S can be applied as is or thinned with special thinner SM-14 by brush, roller or airless gun in 2 coats up to 10% by weight. The second layer should be applied after the first layer has dried, but within 24 hours of its application.
   Use of EPOXYCOAT-S: 200-300 grams per ^square meter per layer.

considerations

• Special attention should be paid to the location of the “special parts” of the pool, such as lights, water inlet and outlet points, etc., which are vulnerable points in terms of waterproofing.
• EPOXYCOAT-S contains solvent. In cases of use in closed rooms, the necessary measures should be taken for proper ventilation.
• The working time of epoxy devices decreases as the ambient temperature increases.
• The bond between successive layers may be severely affected by intervening moisture or dirt.
• Epoxy layers must be protected from moisture for 4 to 6 hours after application. Moisture can make the surface white or sticky. And it can even spoil the hardening.
• If a longer than anticipated time intervenes between the application of successive coats, or if old floors are re-done, the surface shall be thoroughly cleaned and ground before the application of the new coat.
