Substrates
They must be flat, dry, free from dust, grease, or other contaminants that could impair adhesion. Sand metallic surfaces if necessary. After sanding, clean them again. Allow surfaces to dry after degreasing. It is recommended to strip concrete with a wire brush.

Usage advice
Apply using a manual or pneumatic gun. After application, smooth the joint with soapy water using a spatula. This product should be used within 24 hours of opening the cartridge or pouch protection; otherwise, the sealant may harden. In cold weather, store at around 20°C before use. During polymerisation, avoid any contact with hybrid MS PU polymers or unpolymerised silicones, as well as with alcohols or ammonia. Clean tools with methyl ethyl ketone or acetone when the sealant is not polymerised. After polymerisation, abrasion is necessary. Use EMFI products with caution. Before use, read the label and product information.
