Installation
Instructions
Ensure that all the
surfaces are clean, dry, sound and frost free (external application)
clean all joints thoroughly to ensure that the adhesion of the silicone
to the substrate is not impaired.
It may be necessary to mask adjacent areas to prevent contamination and
to ensure a neat sealant line. Masking tapes should be immediately
removed after tooling and finishing.
Install backing materials as required and commence to fill the cavity
or void with silicone.
The joint should be tooled within 5 minutes of the application to
ensure good a contact between the silicone and substrate. Tooling of
the sealant also gives a smooth and professional finish.
Excess silicone should be cleaned off and non-porous surfaces whilst in
an uncured state using a suitable solvent. Sealant adhering to porous
surfaces should be left just until final state for cure is achieved and
then removed by mechanical means.
Dispose of spent cartridges in accordance with local regulations.
