1. For internal applications ensure that all the surfaces are clean, dry, sound and frost free. Clean all joints thoroughly to ensure that the adhesion of the silicone to the substrate is not impaired.

2. 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.

3. Install backing materials as required and fill the cavity with acrylic.

4. The joint should be tooled within 5 minutes of application to ensure good a contact between the acrylic and substrate. Tooling of the sealant also gives a smooth and professional finish.

5. Dispose of spent cartridges in accordance with local regulations.
