Polypol-Decor – epoxy self-leveling floor

Application

Surface preparation:

The metal surface  is cleaned to St2 or Sa 2.5 according to ISO 8501-1 and degreased.

concrete surface:

• carefully grind the base surface with a mosaic or angle grinder with diamond cups;
• dust with an industrial vacuum cleaner;
• the prepared concrete surface should be smooth, even, without grease stains, the moisture content of concrete in the surface layer to a depth of 20 mm should be no more than 4%.

Applying a primer:  apply a primer Polypol-Grunt according to the instructions for its use.

The drying time of the working mixture Polypol-Decor at a temperature of +20°C is 24 hours.

The temperature of the ambient air and surface should be within the range of +10°C to +30°C, but not less than 3°C above the "dew point", the relative humidity of the air should not exceed 80%. The temperature of the working mixture Polypol-Decor should be in the range from +15°С to +25°С.

Operation is permitted:

• after 3 days - pedestrian loading;
• after 7 days - full mechanical load.

With high porosity of the base, but not earlier than after 24 hours, repeat the priming. When priming, avoid the formation of puddles of the working composition. Primer consumption is 0.1 - 0.4 kg / m ²  (depending on the porosity of the base).

Material preparation.

Polypol-Decor: the base (component C) is thoroughly mixed and the hardener (component D) is added in the amount of 18 wt. hours per 100 in. hours of the base, or according to the instructions in the passport and mix thoroughly again. The prepared working mixture is used within 40 minutes from the moment of preparation at a temperature up to +20°C.

During this time, it is necessary to have time to apply and level the material, and when applying a decorative layer, it is also necessary to process it with a spiked roller. At higher temperatures, the pot life of the prepared mixture decreases.

Surface spatula:

In the presence of cracks, potholes, shells in the concrete base, these defects are puttyed, avoiding sagging or unevenness on the floor surface.

Defects in the base with a depth of more than 5 mm are filled with putty prepared by mixing the Polypol-Decor working mixture with dry quartz sand with a fraction of 0.4 - 0.8 mm (5 parts of sand for 1 part of the working mixture). The consumption of prepared putty is about 1.8 kg/l of filling volume.

Base defects with a depth of less than 5 mm are filled with putty prepared by mixing the Polypol-Decor working mixture with Aerosil (for 20 parts of the working mixture 1 part of Aerosil). The consumption of prepared putty is about 0.1 - 0.5 kg/m ² .

Putty the base no earlier than 24 hours after applying the primer. 24 hours after applying the putty, the puttied places are sanded and the entire surface is dedusted. If necessary, puttying is repeated.

Applying a decorative layer:

It is necessary to predetermine the filling configuration so that the perimeter of the filled grips throughout the entire filling period does not exceed the critical value. Namely: a fresh batch of self-leveling floor must be docked with the border of the previous batch no later than 40 minutes after the start of laying the previous batch, otherwise the transition between sections applied in different periods will be noticeable. In case of a break in work exceeding 40 minutes, the area to be poured must first be limited using masking tape. In this case, the transition between different sections will be more even. It is recommended to remove the masking tape no later than 8 hours after applying the bulk coating, otherwise it will be problematic later.

The prepared working mixture is applied in a strip up to 1 m by pouring and leveled over the surface using a squeegee and spatula. The thickness of the layer is regulated by a squeegee. After leveling (after 10 minutes, but no later than 30 minutes), the surface is carefully and evenly treated with a spiked roller to remove air bubbles from the coating.

Work is performed in special shoes on spikes (stupas).

Consumption  for a thickness of 1 mm is 1.5 kg/m ² .
The minimum consumption at which uniform application of the material is possible is 2.0 kg/m ² .
At one time drawing a layer up to 3 mm thick is possible.
