Special heat-expanding paint "OGRAX-VSK". It ensures the creation of a heat-insulating layer on the protected surface. Under the influence of heat, the paint expands and forms a foam that prevents the wood from warming up. The material is a water-dispersion paste created on the basis of a special polymer formula. It is intended for indoor use in rooms with a humidity of no more than 85%.
