What is a primer and what is its application? Construction primer is a type of acrylic chemical compound (soluble in water - ISO paste) or (soluble in gasoO fondo) that is used to cover surfaces or surface substructures to install prefabricated isogum insulation. They use construction primers to prepare the surface for insulation For example, if a precision primer solution is poured on a surface made of cement and the surface is impregnated, it penetrates all the pores of the cement surface to make it impermeable. Also due to the shape, this product, which in the form of paste or nature may also provide coverage of inaccessible surfaces, is made easier with construction primers. In pools, bridges, etc., primer should be used as insulation. It is also used as a strong adhesive and sealant for the whole environment by producing a thick primer.
