How to use

  • It’s recommended to apply the product at an ambient temperature from +5°C to +40°C. The temperature of the sealant should be +20°C… +25°C.
  • Apply the sealant to clean, dry, degreased surfaces.
  • Protect surfaces with masking tape to ensure an accurate application.
  • Cut off the tip of the cartridge above the screw thread, screw on the nozzle, unscrew the nozzle cap and cut off the nozzle diagonally (at an angle of 45°) according to the diameter of the joint width.
  • 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 smoothing.
  • Remove the sealant from tools and surfaces using a solvent (white spirit, or acetone) before the sealant has cured.
  • Remove cured sealant using mechanical methods.

Note! The sealant may be tinted over time if blue chemicals are added to the aquarium!

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. Do not paint over!
