  • It is advisable to conduct work at temperatures from +5˚C to +40˚C; the sealant temperature must be +20°C to +25°C.
  • Apply the sealant to clean, dry and degreased surfaces.
  • It is recommended that adjacent surfaces should be covered with masking tape to do the work cleanly.
  • 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 and remove the masking tape immediately after the smoothing.
  • Remove the sealant from tools and surfaces using a solvent (white spirit, or acetone) before the sealant has hardened.
  • Remove cured sealant using mechanical methods.
  • Skin Time – 10-12 minutes, sealant curing rate – 3 mm per day (at +23°C and 55% relative humidity).
  • Operating temperature: from -50˚C to +120˚C.
  • 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.
