  • Easy to use: Excellent flow characteristics make Bostik’s smoothing compounds easy to apply.
  • Fast-curing: Many of our smoothing compounds contain a rapid-setting formula, which accelerates floor preparation and installation times.
  • Flexibility: Bostik’s subfloor products are ideal for a wide range of substrate applications, from concrete and sand/cement screeds to stone, rigid metal and wood.
  • Polymer-modified: Bostik’s cementitious products have high polymer content for excellent adhesion, strength and flexibility.
