Instructions for Use/Application Instructions The following should only be used as a guide and the installer should apply all Australian Standards, BCA/NZBC requirements, and best practices when installing. Surfaces to be sealed must be clean, dry and free from dust, grease, old mastic and flaking paint. If necessary clean with degreasing solvent such as white spirits. Cut nozzle supplied at an angle and to the required opening. Cut end off nipple on cartridge, fit nozzle and insert in suitable caulking gun. If sealing lap joints, apply suitable size bead of Butyl Mastic to one surface through the intended fasten line. Bring surfaces together squeezing the mastic bead out on both surfaces and mechanically fix join where necessary. If sealing open joints, apply Butyl Mastic by forcing it into the joint ahead of the nozzle. This method aids in properly filling the joint and forcing mastic to wet on to the sides of the joint. If required, smooth surface with spatula dipped into mineral turpentine.
