One component, 100% solids, polyurethane based primer

MICROSEALER-PU is a one component, 100% solids, polyurethane based primer suitable for all substrates. It is characterised by its very low viscosity and balanced curing speed which result in excellent wetting, impregnation and paint-over time on all substrates, whether of high, low or no porosity (e.g. glass and metals).  Additionally, it can be effectively used on both dry and wet concrete, even green concrete, not only as primer but also as a low-cost sealing solution, increasing, thus, the durability of the substrate.

The cured film displays outstanding mechanical properties: Its elongation is 400%, i.e. it matches perfectly that of the HYPERDESMO® System, and its tensile strength surpasses 20 N/mm2.

Apply with brush or roller.  Consumption: 100-500 gr/m2, subject to substrate porosity.


To be used as primer for:

  • Humid, damp or wet concrete,
  • ceramic tiles,
  • other non-porous substrates like glass, marble & metals.

Also, for use as concrete sealer.
