What does it do?
Suitable for sealing slightly working joints, seams and cracks in door and window frames, window sills, prefabricated elements, stairs, skirting boards, walls, drywalls, ceilings, corrugated sheets and conduits. Also suitable for sealing tears and cracks in interior walls. Adheres to bricks, (cellular) concrete, masonry, plasterwork, wood, glass, ceramic tiles, metal and rigid PVC. Does not adhere to bitumen, PP, PE, PTFE and silicone. For sealing window glass use Bostik Glazing Sealant.
Only apply at temperatures between +5°C and +40°C.
The surface must be dry, clean and free of dust, rust and grease.
Preliminary surface treatment
For a better adhesion on porous (highly porous) substrates, they should be first covered with a diluted acrylic solution (1 part sealant to 2 parts water). For a good result, cover the joint’s edges with masking tape. Ensure a minimum joint width of 6 mm. Up to a joint width of 12 mm, ensure a joint depth of 6 mm. In case of wider joint widths, the joint depth should be half the joint width. Remove masking tape immediately after tooling.
Apply cartridge with a Power Pistol. Multi Tool to open the cartridge and tooling the sealant.
Handling of packaging
Use sealant gun to handle cartridge. Open the cartridge by cutting off the plastic nipple on the top side at the screw thread with a sharp knife. Screw on the nozzle and chamfer at the desired width.
Directions for use
Turn the synthetic nozzle of the tube and remove aluminium protective film from the tube. Insert the nozzle again on the tube and cut it at an angle to the desired opening. For a good result, cover the joint’s edges with masking tape. Ensure a minimum joint width of 4 mm and a maximum of 20 mm. Prevent three-sided bonding by filling the joint with a foam backer rod or PE film. Inject the sealant evenly into the joint and tool within 10 minutes with a wet putty knife or Bison Multi Tool. Remove the applied masking tape immediately after tooling. After 15 minutes, a surface skin will form. The sealant is paintable after 30 minutes when using a water-based paint, and after 2 hours when using a solvent-based paint.
Points of attention
The sealant is all-weather resistant upon complete curing. After 30 minutes a surface skin will form that is strong enough to be painted. The sealant will shrink as it dries. A non-elastic paint may therefore tear as a result of the sealant’s shrinkage.
Remove wet stains immediately with water. Cured sealant residue can only be removed mechanically.
Store in well-sealed packaging in a cool, dry and frost free place.
