• Ensure surfaces are clean, sound, and free from dust, grease, loose material, old sealant, or loose coatings.

• Prime highly porous surfaces (such as new plaster) if required using a suitable PVA primer mix as recommended.

• Surfaces may be slightly damp, but must not be wet (damp conditions will slow curing).

• Load the cartridge into a compatible jumbo mastic gun.

• Cut the nozzle to the required bead size and puncture the membrane before application.

• Apply a continuous bead to the joint, gap, or bonding area and tool as required for a neat finish.

• For board bonding, apply beads at suitable centres, fix boards immediately, and support until cured.

• For overhead boarding, always use in conjunction with mechanical fixings.
