FP MX 251

Epoxy floor coating primer, solvent free

Numastec FP MX-251 is a transparent, rigid, two-component epoxy solvent-free primer I coating mainly used as a primer in floor coating applications. Cures by reaction (crosslinking) of the two components.

  • Simple application.
  • Excellent anchoring to the surface
  • Provides high tensile and impact strength.
  • Heat and frost resistant.
  • Stops the creation of dust.
  • Chemical resistant.

The Numastec FP MX-251 is mainly used as a primer for polyurethane and epoxy floor coating surfaces like.

  • Concrete
  • Power floated concrete
  • Metal (various)
  • Asphalt
  • Wood, 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 at least 25 MPa, cohesive bond strength at least 5MPa. New concrete structures need to dry for at 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.
