PS-Grunt — polyurethane primer for concrete and asphalt concrete floors
One-component moisture-curing polyurethane primer for KRASKO enamels and self-levelling floors; hardens and dustproofs the substrate.

Tsinkonol is a one-component compound for “cold galvanising”: zinc powder is dispersed in a solution of a polyurethane prepolymer, and the coating cures with atmospheric moisture. It is used on steel structures, bridges, pipelines, tanks, oil and gas facilities, marine structures and equipment, as well as for restoring hot-dip galvanised surfaces. The material works on its own or serves as a primer under the Poliuretol UV and Epostat enamels and allows welding through the coat; with polyurethane enamels the system lasts up to 25 years in temperate and cold climates.
