Base

The substrate must be solid, clean, free of dust, rust and oil stains to aid adhesion of the epoxy.

Foundation preparation

The base must first be treated mechanically - shot blasting, sandblasting and grinding, followed by removal of dust and dirt with a powerful industrial vacuum cleaner.  

 

Epoxy Pool Paint

Foundation quality

Cement-concrete bases must meet the following main criteria:

• Surface strength ≥ 1.5 N/mm2;

• Humidity ≤ 4%;

The prerequisite for the above requirements are:

• concrete grade: not less than C 20/25;

• cement screed quality: cement content ≥ 350 kg/m3;

• age of the cement-concrete base > 28 days;

• the epoxy coating process should not take place in a humid environment and especially in the presence of water vapor. 

• vapors will adversely affect the adhesion of the material, and will contribute to its eventual delamination from the substrate. 

• it is necessary to foresee the exclusion of such conditions in advance.

 

Epoxy Pool Flooring

Padding

• Porous, concrete-cement substrates, before applying VIMEPOX SP-COAT, are  coated with a transparent epoxy primer with VIMEPOX PRIMER-S or VIMEPOX SP-COAT thinned with 10% VIMEPOX SOLVENT;

• The purpose of the primer is to fill existing pores, which will help produce a uniform finish after the epoxy has been applied.

Preparation of the mixture (kneading)

• Components A (resin) and B (hardener) are packed in the required proportions. 

• Therefore, when mixing, the need to weigh them is eliminated, except when a smaller amount needs to be mixed .;

• Before mixing the components, it is recommended to shake them up and mix them in a clean container using a mixer with low speed (300 rpm);

• Mixing time of the components to achieve a homogeneous mass ~ up to 5 minutes.

Laying

VIMEPOX SP-COAT  can be applied to the surface with a special roller (short-haired) or with a spray gun.

Finish coating (paint) for outdoor concrete floors and pools

• Prepare the epoxy mixture (see above);

• Apply primer VIMEPOX PRIMER-S;

• Consumption: 0.20-0.30 kg/m2 depending on the absorbency of the substrate;

•  Apply VIMEPOX SP-COAT using a roller in 2-3 coats;

• Consumption: 0.20-0.25 kg/m2 for each layer;

•  Apply the next layer only after the previous one has dried;

• The waiting time is 16-20 hours (at 20°C) and should not exceed 24 hours;

• The total thickness of the coating: primer and 2 coats of paint (x 0.25 kg/m2) does not exceed 400 microns.

 Non-slip coating for concrete floors

• After the first application of VIMEPOX SP-COAT,  sprinkle a fresh coat with M 31 quartz sand (0.1 - 0.7 mm). After the epoxy has hardened, remove excess sand with an industrial vacuum cleaner;

• Then apply 2 to 3 coats of VIMEPOX SP-COAT, depending on the degree of anti-skid you want to achieve.

Epoxy materials for the pool

General remarks

• For VIMEPOX SP-COAT to harden, the ambient temperature must be at least 10-12οC, while the substrate temperature is below 8οC;

• Relative humidity should not exceed 70%. Otherwise, it is possible:

  - loss of surface gloss (matting effect) and in the worst case;

  - the appearance of a non-hardening film, which must be removed by sanding and water;

• The negative effect on the adhesion of subsequent layers is affected by the humidity or dirt of the base; 

• Humid air or direct exposure to water on a freshly painted surface up to 6 hours after installation may cause discolouration or a sticky surface.

• In this case, the surface must be sanded and repainted;

• If more time elapses between the application of the previous and subsequent coats of VIMEPOX TOP-COAT than is permissible, then such a surface must be sanded using a mosaic machine. 

• Then vacuum the surface with an industrial vacuum cleaner. 

• Only then can the surface be painted again.

Tool Care

Tools should be cleaned with VIMEPOX SOLVENT immediately after use.

Storage and packaging

• VIMEPOX SP-COAT  should be stored in closed containers, in rooms with a temperature not lower than +10°C in winter and in the shade in summer.

• Shelf life is at least 24 months.

Note and Precautions

• Both resin and hardener VIMEPOX SP-COAT must not come into contact with eyes and skin. 

• Inhalation of vapors should also be avoided;

• Personnel working with this material must be protected with rubber gloves and goggles;

• If the skin comes into contact with resin, hardener or mixture, it should be dried with a paper towel and then washed with cold water and soap (recommended to add 2% vinegar);

• If the material gets into the eye, it should be flushed with plenty of cold water for 10-15 minutes, and then an ophthalmologist should be consulted;

• Once hardened, VIMEPOX SP-COAT  is completely harmless to health.
