How to Use:

Sealing Application:

The joint width must be designed to suit the movement capability of the sealant. In general, the joint width must be > 10 mm and < 35 mm.
A width-to-depth ratio of approx. 1:0.5 must be maintained. Fill deep joints with a PE foam ‘Backer Rod’ prior to applying the sealant.
Cut off the tip of the cartridge above the screw thread. Screw on the plastic nozzle and cut off the tip of the nozzle. Place cartridge into gun.
Insert the cartridge into the sealant gun and firmly extrude the Seal and Bond into the joint, making sure that it is in full contact with the side of the joint. Fill the joint, avoiding air entrapment. Seal and Bond must be tooled firmly against joint sides to ensure good adhesion.
Masking tape must be used where sharp exact joint lines or exceptionally neat lines are required. Remove the tape whilst the sealant has still not formed a skin.
After application, the product can be smoothed with Unibond Sealant Smoother Tool before skinning for a perfect sealant surface.
Bonding Application:

Apply adhesive onto the surface of one of the elements to be bonded: In spots to smooth uneven surfaces, in wave-like form for higher initial tack with large surfaces or in straight beads for smaller surfaces. Release gun after appliance to stop the adhesive flow. (Not valid for Foldable Gun DW111/120).
Firmly fix items to be bonded into position with a twisting action. If necessary (e.g., heavy items and items under tension), support the items until cured. Items can be adjusted after application. The minimum thickness of the adhesive layer should be 1 mm to ensure ventilation.
In the case of outdoor use, apply vertical strands. Use hand pressure to set the element to be bonded into position. If necessary, use adhesive tape, wedges, or props to hold the assembled elements together for the initial hours of curing.
An incorrectly positioned element can be easily unfastened and repositioned in the first few minutes after application. Apply pressure again.
Optimum bonding will be obtained after complete curing of Seal and Bond, i.e., after 24 to 48 hours at +23°C for a thickness between 2 to 3 mm.

Drying Time: The sealant will be touch dry in 30 mins. Cures in approx. 24-48 hours at +23°C for a thickness of 2-3mm. Wait until the product is fully cured before applying loads or exposing it to water.

Please note: The joint must be cleaned and maintained regularly. Ensure good ventilation in the room where the sealant is applied if using indoors.
