Thermal insulation coating Thermo-S

General information

Liquid thermal insulation hit the market back in the 90’s, but it has become really developed in the last several years. Latest scientific discoveries as well as advanced technology are being used in the production of modern components.

Paints with insulating properties have passed laboratory tests, are properly licensed and are used extensively in developed countries for protection against corrosion, energy saving, as well as for useful life extension of covered surfaces. Liquid insulation has been widely used in industry and everyday life: buses, cars, trains, private buildings, ventilation, roofing, agriculture – it is not an exhaustive list of the areas where thermo insulating paints are applied.

Let us examine how the liquid thermal insulation works. Heat is infrared radiation. Object releasing heat into the atmosphere loses it. Ordinary thermal insulation with greater or less success retains heat, while thermal insulating paint “reflects” it, returning almost 70% of the heat back.

This happens due to technologies that create a vacuum environment inside the coating (due to the air microscopic hollow balls), which provide the necessary thermal conductivity. At the same time a small portion of the heat still passes through the coating, which protects the treated surface from damage that could occur in case of total absence of  “breathing”.

In addition to heat reflection liquid insulation contributes to noise reduction and heat saving. If you apply the paint in a basement or cellar humidity will be significantly reduced and this will prevent mold growth. The application of thermal insulation on facades of apartment buildings and hall walls allows to save on heating costs and eliminates condensation. Windows  do not freeze and pipelines are also additionally protected.

The price of liquid insulation is consistent with the quality and excellent properties. It can reduce the heat loss by 30%, while the consumption of such paints is about one kilogram per square meter of the surface.

However, you must always follow instructions when applying the coating, because the manufacturer will not be able to guarantee reliability of the coating  in case of non-compliance.

Liquid insulation can be applied on surfaces like wood, brick, concrete, glass, rubber, plastic, cardboard etc.

Main advantages

  • ENERGY SAVING (thermal insulation)

    Energy savings for heating and cooling of any buildings / premises / facilities / structures.


    Protection of any metal surface from corrosion.


    Moisture inside the coating does not appear due to the temperature difference.


    Protection of any surface from moisture.


    Coating is completely safe for humans and the environment. We hold necessary ecological certificates.


    Coating is suitable for application outside and inside of any building / room / facility / structure.


    The coating has excellent adhesion to almost any material.


    Since the coating is liquid paint, it can be applied on any shape of the surface.


    Coating is available in two versions:

    • Water-based (suitable for application on the surface at temperatures above 5 degrees Celsius);
    • Based on organic solvents (may be applied at temperatures below freezing and above freezing).

    Coating is easy to apply.


    The coating can be applied by mechanical (brush) and automatic (airless machine) means.


    Coating is applicable for finish cover and requires no external decoration.The coating is white and therefore any color paint can be applied on it.


    In dry form 1 cubic meter of the coating weights 300 kg, i.e. the coating in dry form is lighter than water by three times.


    Coating may be applied even on fabric and coiled.


    The effective thickness of dry coating layer begins from 1 mm.


    Minimum useful life of the coating is 10 years.

Application guide

1. Instructions for use.

1.1. Preparation of the coating.

Any coating of SPA Zelenopol is supplied ready for use.

Before applying the coating it must be mixed with a hand mixer (drill is not preferable) to obtain homogeneous mass, with a mandatory immersion of nozzle down to the bottom of the bucket.

Do not use high speed while stirring the coating!

1.2 The order of coating application to metal, concrete, brick, wood and other surfaces.

Preparation of metal surface for application.

  1. thoroughly clean the surface from rust;
  2. if necessary treat the surface with rust converter;
  3. dry the treated surfaces;
  4. cover the metal surface with a thin layer of anticorrosion primer brand GF-021. The thickness of the layer should be not less than 50 microns, the drying time 72 hours.

Preparation of concrete, brick, wood and other surfaces for application.

  1. thoroughly clean the surfaces: remove loose parts, cracks, oily inclusion and gloss.
  2. apply 1 or 2 coats of deep soaking primer;
  3. dry the treated surfaces.

The technological process of coating application on metal, concrete, brick, wood and other surfaces.

Apply the coating with a thin layer on prepared surface covered with primer (thickness should not exceed 400 micrometers). Apply the paint with a soft brush with a long nap or airless spray (devices like «Vagner»). Dry for 24 hours at a temperature of 20 ° C and humidity no more than 85%.

In case of brushing, the brush should be preliminary dipped in *solvent during the application process.

The paint must be under constant stirring during application process, so that the fluid is not collected at the bottom of the container.

The following layers (of thickness no more than0 500 microns) must be applied under normal conditions after drying of the previous layer to form the required coating thickness. The drying time is 24 hours at a temperature of 20 ° C, humidity no more than 85%.

Upon agreement with manufacturer, the coating can also be applied on a heated surfaces (up to 150° C).

In this case the thickness of each of the first three layers should not exceed 50 microns, and each layer must be dried for at least two hours. A *solvent must be added to the coating to achieve this.

The amount of *solvent depends on the object surface temperature and the ambient temperature.

After coating application, brushes and other equipment must be thoroughly washed in *solvents.

2. Manufacturer warranty.

The manufacturer guarantees the compliance of the coating with specification requirements. Subject to the conditions of transportation and storage, the warranty period of coating storage is 12 months from the date of manufacture.

Beyond the warranty period of storage, the coating is subject to re-examination for compliance with specifications. Upon receipt of positive results the coating can be used for the intended purposes.

3. Storage conditions.

Store the coating in tightly closed containers at a temperature:

  • from -30 ° C to +35 ° C for solvent-based coating
  • from +5 ° C to +35 ° C for water-based coating.


  • if the coating is solvent based it may be diluted with xylene or butyl acetate;
  • If the coating is water-based it may be diluted with water only.
