Microsealer PU®

       
 

Low viscosity, solvent-free, polyurethane based primer / concrete sealer,
for both porous & non-porous substrates, and both dry & wet concrete.

   
 
 

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.

 

Recommended as Primer for:

  • wet / moist concrete

  • ceramic tiles

  • non-porous substrates like glass, marble and metal

  • concrete protection

 

Shelf Life:

Can be kept for 12 months minimum in the original unopened pails in dry places and at temperatures of 5-25°C. Once opened, use as soon as possible.

 

Packaging:

1kg, 5kg and 20kg pails

 

   

Features & Benefits

  • One component. 

  • Of low viscosity.

  • Easily appliable, even on wet concrete.

  • Adheres strongly, even on glassy, non-porous substrates.

  • Excellent wetting, impregnation and paint-over time.

  • Elastic.

  • Solvent-less, suitable for application in closed spaces.

  • Many pigment pastes available.

  • A low-cost solution for concrete sealing & protection.

 

Application:

Apply with brush or roller. Once cured, the main
membrane (e.g. HYPERDESMO® System) can be applied

 

Consumption:

100 - 500gr /m², subject to substrate porosity.

 

Cleaning:

Due to the very high strength of adhesion of MICROSEALER-PU, avoid staining surrounding areas. Clean tools and equipment first with paper and then using SOLVENT-01. Rollers will not be re-usable
