  • Best Practices for 3M 08019

    *See Terms of Use Below

    1. Surface Preparation

      There are waxes, coatings, sealants, grease, oil and other contaminants used in the marine industry, making it very important to clean all surfaces to be bonded before applying 3MTM Marine Grade Silicone Sealant. Recommended procedures include cleaning with 3M TM General Purpose Adhesive Cleaner, P. N. 08984.

      When using solvents, use in a well ventilated area. Extinguish all sources of ignition in the work area and observe proper precautionary measures for handling such materials. Refer to product label and MSDS for further precautions.

      Local and Federal air quality regulations may regulate or prohibit the use of surface preparation and cleanup materials based on VOC content . Consult your local and Federal air quality regulation.

    2. Clean-Up

      For cleaning 3M Marine Grade Silicone Sealant before it is cured, use a dry cloth to remove the majority of sealant, followed by a cloth damp with 3MTM General Purpose Adhesive Cleaner, P. N. 08984, toluene or acetone.
