FP MP 71

Polyurethane floor coating

The Numastec FL MP-71 is a colored. one component, highlydurabte. aromatic potyurethanethin-tayerfloor coating.

The Numastec FL MP-71 is specially designed for use as a floor coating, providing high mechanical strength, high abrasion and chemical resistance.

Cures by reaction with ground and air moisture.

  • Simple application (roller or airless spray).
  • High abrasion resistant.
  • Decorative.
  • Resistant to constant,heavy abrasion and wear conditions.
  • Heat and frost resistant.
  • When applied does not absorb liquids or dirt.
  • Gives a glossy and easy-to-clean surface.
  • Chemical resistant.
  • Maintains its mechanical properties over a temperature span of -20 °С to +90 °С

The Numastec FL MP-71 is mainly used on concrete floors , on interior surfaces.

Due to its long lasting unchangeable properties is widely used for:

  • Car repair garages
  • Car parking areas
  • Warehouses
  • Storage rooms
  • Factories
  • Animal breading farms
  • Cold storage rooms (Freezers), etc

Surface Preparation

Careful surface preparation is essential for optimum finish and durability.

The surface needs to be grinded with a stone- or a diamond-grinding machine. The surface needs to be clean, dry and sound, free of any contamination, which may harmfully affect the adhesion of the coating. Maximum moisture content should not exceed 5%. Substrate compressive strength should be alleast 25MPa. cohesive bond strength at least 1.5MPa. New concrete structures need todryforat least 28 days. Old coatings. dirt, fats. oils. organic substances and dust need to be removed by a grinding machine. Possible surface irregularities need to be smoothened. Any loose surface pieces and grinding dust need to be thoroughly removed.

WARNING: Do not wash surface with water!

WARNING: Do not use a metal-bait blasting machine to grind the surface, because the heavy metal-batt impacts destroy the cohesion of the concrete surface and lower its stability.
