Microsealer® 50 is a one-component, solvent based, low viscosity polyurethane based primer suitable for many different substrates.
It is characterised by its very low viscosity and balanced curing speed which result in excellent wetting, impregnation and paint-over time on different substrates of high, low or no porosity (e.g. glass and metals). It can be used effectively on both dry and wet concrete, even green concrete, not only as primer but also as a low-cost sealing solution, increasing the durability of the substrate.
