Mixing instructions

  • No mixing required.

Application or directions for use

  • Cut the tip of the cartridge and screw the nozzle on.

  • Cut the tip of the nozzle at an angle to suit your required bead size.

  • Use masking tape to get a clean and even sealant line. Remove the tape before the sealant begins to form a skin.

  • Apply with a caulking gun in a continuous bead.

  • Masking tape can be used on surfaces to get a clean even line and to reduce cleaning efforts.

  • Smooth down the sealant within 3-5 minutes after application before the skin has formed.

  • The sealant will be touch dry within 1 hour and fully cured after 24 hours.


  • Clean tools immediately after application with a cloth soaked in a solvent like turpentine or thinners.

  • Cured sealant can be removed mechanically with a sharp knife or similar tool.


  • Store in a cool and dry place out of direct sunlight in the original container.

  • Keep the container tightly sealed.

  • Keep out of reach of children and pets.


  • If stored correctly the sealant has a shelf life of up to 18 months.

  • The sealant is not necessarily unusable after this time, but it is recommended that an adhesion test be done before using.

  • Life of the sealant can be extended by placing a piece of plastic over the opening and screwing the nozzle back on to create an airtight environment.



  • Wear the appropriate safety gear like gloves and safety goggles.

  • Avoid direct skin contact or eye contact. In the event of contact rinse thoroughly with clean cold water. Seek medical attention if irritation persists.

  • Do not ingest the product. In the case of ingestion, seek medical attention immediately. Do not induce vomiting.

  • Work in a well-ventilated area and avoid prolonged inhalation.


  • Not recommended for alkaline surfaces like concrete and coarse cement. This is because ALCOLIN K86 SILICONE SEALANT releases acetic acid while it dries.

  • Should not be used on certain metals like galvanised iron or lead because the product can cause deterioration or corrosion.

  • Discolouring may occur if it makes contact with organic elastomers (e.g. some rubbers and paint).

  • Not recommended for use on mirrors since it will discolour the silver coating on the back.

  • May discolour natural stone surfaces like marble and is therefore not recommended for use on these surfaces.

  • It will not stick on certain plastics like Teflon (e.g. pan coatings), polyethylene (e.g. grocery bags and shampoo bottles) and polypropylene (e.g. model planes or cars).

  • Attempts to paint over it will not give ideal results.

  • It contains fungicide and is therefore NOT RECOMMENDED FOR FISH TANKS.

  • Should not be used in very dry weather (relative humidity below 10%) since the product will take longer to cure.
