Method of manufacturing of the thermoactive acrylic paint containing fillers, pigments, flame retardants, surface-active agents, silicates, acrylic copolymers, and glass microspheres, characterised in that on the first stage Premix 1 is manufactured by placing in a mixer 46 to 50 wt % of 45-48% of water dispersion of acrylic copolymers and while continuously mixing with the stirrer speed of 120 to 160 rpm, the dispersion is heated up to the temperature of 30 to 40°C, and afterwards the following are added: - 50% water solution of polymeric dispersant in the quantity from 1.3 to 1.6% wt %, - anti-foaming agent in the quantity from 0.75 to 0.85 wt %, - 100% surface-active alkanodiol agent in the quantity from 1.4 to 1.5 wt %, and also a - surface-active siloxane agent in the quantity from 1.3 to 1.5 wt % and the whole is homogenised for 9 to 10 min, and then 19 to 20 wt % of titanium dioxide (TiO 2) are added and further homogenised dynamically for 15 minutes at least, and afterwards the following are added subsequently: - micronized calcium carbonate in the quantity from 12 to 13 wt %, - micronized kaolin (4SiO 2 x2Al 2 O 3 x4H 2 O) in the quantity from 4.2 to 4.6 wt %, - coalescent in the quantity from 1.4 to 1.5 wt %, - isopropanol in the quantity from 2.2 to 2.4 wt %, - hydrophobically modified ethylene oxide-urethane block copolymer in the quantity from 2.0 to 2.4 wt %, and - demineralised water in the quantity from 4.0 to 4.5 wt % and the whole is mixed for 20 to 30 minutes maintaining the temperature within the range of 30 to 40°C, and the Premix 2 is made by placing demineralised water in the quantity from 42 to 45 wt % in the mixer and while mixing it is heated up to the temperature of 30 to 40°C, and then the following are added: - surface-active siloxane agent in the quantity from 0.4 to 0.5wt %, - 26% water solution of polyethersiloxane defoamer with silica in the quantity from 0.8 to 0.9 wt %, - from 1 to 20 ppm of water solution of metallic silver nanoparticles having the size within the range between 3 to 15 nm embedded on a polyphenol matrix - 50% water solution of non-ionic polymeric dispersant in the quantity from 1.2 to 1.6 wt %, and the whole is dynamically mixed with the stirrer speed maintained at 300 to 500 rpm until a completely homogenised mixture is obtained however, for 20 min minimum, then the stirrer mixing speed is reduced to 30 to 40 rpm and the following are added: - powdered copolymer of vinyl acetate and vinyl EDTA with an additive of polyvinyl alcohol in the quantity from 26 to 29 wt %, and - from 20 to 24% wt % of borosilicate glass microspheres of particles density within the range from 0.125 to 0.6 g/ml, average particle size of 10-120 microns, wall thickness 0.5-1.5 microns and compressive strength of 17-1,240 bar and the whole is further homogenised for 10 to 15 min, and then with the mixing continuously maintained 3.9 to 4.4 wt % of bonding agent are added and the process is continued until complete homogenisation is obtained within 20 to 30 min, and then, the previously prepared Premix 1 in the quantity from 60 to 70 wt % is placed in the mixer and for 25 to 35 min while being continuously mixed with the stirrer speed from 100 to 120 rpm it is heated up to the temperature of 30 to 40°C, and subsequently with mixing and temperature maintained at 30 to 40°C, the previously prepared Premix 2 is added in the quantity from 30 to 40 wt % and homogenisation process is conducted for 25 to 35 min with the temperature maintained within the range of 30 to 40°C, and then the stirrer rotation is reduced to 30 to 40 rpm, and with mixing continued the whole is still homogenised for 10 to 30 min with the temperature maintained within the range of 30 to 40°C. - 50% water solution of polymeric dispersant in the quantity from 1.3 to 1.6% wt %, - anti-foaming agent in the quantity from 0.75 to 0.85 wt %, - 100% surface-active alkanodiol agent in the quantity from 1.4 to 1.5 wt %, and also a - surface-active siloxane agent in the quantity from 1.3 to 1.5 wt % and the whole is homogenised for 9 to 10 min, and then 19 to 20 wt % of titanium dioxide (TiO 2) are added and further homogenised dynamically for 15 minutes at least, and afterwards the following are added subsequently: - micronized calcium carbonate in the quantity from 12 to 13 wt %, - micronized kaolin (4SiO 2 x2Al 2 O 3 x4H 2 O) in the quantity from 4.2 to 4.6 wt %, - coalescent in the quantity from 1.4 to 1.5 wt %, - isopropanol in the quantity from 2.2 to 2.4 wt %, - hydrophobically modified ethylene oxide-urethane block copolymer in the quantity from 2.0 to 2.4 wt %, and - demineralised water in the quantity from 4.0 to 4.5 wt % - surface-active siloxane agent in the quantity from 0.4 to 0.5wt %, - 26% water solution of polyethersiloxane defoamer with silica in the quantity from 0.8 to 0.9 wt %, - from 1 to 20 ppm of water solution of metallic silver nanoparticles having the size within the range between 3 to 15 nm embedded on a polyphenol matrix - 50% water solution of non-ionic polymeric dispersant in the quantity from 1.2 to 1.6 wt %, - powdered copolymer of vinyl acetate and vinyl EDTA with an additive of polyvinyl alcohol in the quantity from 26 to 29 wt %, and -
