How to use

  • It is advisable to conduct work at temperatures from +5˚C to +40˚C; the sealant temperature must be +20°C… +25°C.
  • Apply the sealant to clean, dry and degreased surfaces.
  • To do the work neatly, protect adjacent surfaces with masking tape.
  • Cut the tip from the cartridge above the screw thread, screw the dispensing nozzle onto the cartridge, unscrew the nozzle cap and trim the nozzle diagonally (at an angle of 45°) to fit the width of the joint.
  • Use a cartridge-operated gun for application.
  • Smooth down the sealant in the joint with a wet putty knife. Remove the masking tape immediately after the smoothing.
  • Remove excess sealant from tools and surfaces using a solvent (acetone, or white spirit) before the sealant has hardened.
  • Remove cured sealant using mechanical methods.
  • It is not recommended to use the sealant when dealing with natural stone (marble or granite), metal surfaces prone to corrosion (lead, copper, zinc, or brass), or concrete, cement, plastered surfaces, as well as when working with mirrors.
