Painted Surfaces
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 mineral turps.
Cut nozzle supplied at an angle and to the required opening. Cut tip off cartridge, fit nozzle and insert in suitable caulking gun such as Selleys Light Speed caulking gun.
If sealing lap joints, apply suitable size bead of D-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 D-Mastic 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 turps or kerosene.
Limitations:
Not an elastomeric compound, it should not be used in joints subject to considerable dynamic movement.
Maximum service is achieved when used within joints; it is not recommended to be used as a"skim" coating over joints.
Not recommended for use in joints required to resist static air or water pressure.
