Instructions for Installation:

• Surfaces must be firm, clean free of dust and loose particles.
• The cavity or voided area to be filled must be moistened well with water, this will aid installation adhesion to the substrate.
• Shake the can thoroughly, until the foam inside becomes liquid.
• Then attach the straw to the canister and commence to fill the cavity from the base of the aperture slowly and build up the layers of the foam, ensuring that the void is filled.
• Care to be taken not to over-fill the cavity.
• As a rule, only fill the cavity approximately half full as post expansion will fill the hole.
• Allow the foam to cure – full cure will be reached in approximately 24 hours. Cured foam can be cut using a sharp bladed instrument.
• Protect the foam from exposure to direct sunlight as polyurethane foam is not UV stable. Protect exposed foam from UV with plaster or paint.
