CHARACTERISTICS:
MICROSEALER-50 is a one component, low viscosity, polyurethane based primer suitable for many different substrates. It is characterized by its very low viscosity and balanced curing speed which result in excellent wetting, impregnation and paint-over time on different 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 >300%, and its tensile strength surpasses 30 N/mm2. Apply with brush or roller. Consumption: 100- 200gr/m2, subject to substrate porosity.

LIMITATIONS:
Clean the surface using a high pressure washer, if possible. Remove oil, grease and wax contaminants. Cement laitance, loose particles, mould release agents, cured membranes must also be removed. If there are surface irregularities, we recommend charging MICROSEALER-50 with sand. Apply with brush or roller. Once cured, the main membrane (e.g. HYPERDESMO System) can be applied.
Clean tools and equipment first with paper and then using SOLVENT-01. Rollers will not be reusable.
1 Lt, 4 Lt, 20 Lt.
Can be kept for 12 months minimum in the original unopened pails in dry places and at temperatures of 5-25 oC. Once opened, use as soon as possible.
Contains volatile flammable solvents. Apply in well-ventilated, no smoking areas, away from naked flames. In closed spaces use ventilators and carbon active masks. Keep in mind that solvents are heavier than air so they creep on the floor. The MSDS (Material Safety Data Sheet) is available on request.
