Sikafloor®-140 W Troweling Primer

Bonding agent for SikaScreed® HardTop Systems

Sikafloor®-140 W Troweling Primer is a patented bonding agent for SikaScreed® HardTop systems. It improves resistance to peeling, enlarges the time for coating and reduces the dependance on climatic conditions like temperature and air humidity for subsequent resin coatings.

  • enlarges the time window for subsequent coating
  • improves the bonding between substrate and epoxy coatings
  • improves mechanical surface strength of SikaScreed® HardTop
  • solvent free
  • not flameable

Usage

Applied to SikaScreed® HardTop in a thin layer, Sikafloor®-140 W Troweling Primer enlarges the time window for overcoating with reactive flooring systems. Due to the chemical bond between substrate and coating, the peel adhesion is improved by a factor of approximately 10 in comparison with non-treated systems. Sikafloor®-140 W Troweling Primer is sprayed onto the surface of SikaScreed® HardTop immediately before starting smoothing the surface. It has to be well worked into the substrate.  

Advantages

  • enlarges the time window for subsequent coating
  • improves the bonding between substrate and epoxy coatings
  • improves mechanical surface strength of SikaScreed® HardTop
  • solvent free
  • not flameable
