DEMCO PUR 310 MIDCOAT, is a solvent-free, two-component, elastic, polyurethane skimming, filling, and leveling putiy. In tartan tracks, filling the pores of rubber granule felt; It is used as a filler and stripping paste in elastic polyurethane flooring systems.


  • It provides a smooth surface by filling the pores in the rubber granule seal structure. In this way, no air bubbles occur in the coating to be applied on it. It ensures that the film surface of the elastic polyurethane coating to be applied on it is more homogeneous and smooth.
  • It protects the elasticity of rubber granule felt.
  • It reduces the consumption of the coating to be applied on it
