Application

Surfaces to be sealed must be clean, dry and free from dust, dirt, frost, grease and other contamination. Cut both the cartridge tip and applicator nozzle to the required diameter and angle, screw nozzle onto cartridge. Apply sealant with applicator gun ensuring good surface contact is achieved by forcing sealant into the joint to be sealed. If necessary, tool within 5 minutes of application using a spatula dipped in soapy water, apply sufficient pressure to ensure good contact of the sealant against the joint surfaces. Ensure that a depth of mastic of at least 20mm can be achieved. Gaps deeper than this may be back-filled with conventional foam material or mineral wool as required. For gaps not more than 10mm width a 10mm depth of mastic is sufficient.
