Preparation of the substrate:
1. Surfaces must be firm, clean, free of dust and loose particles. The cavity or voided area to be filled must be well moistened with water, this will aid installation adhesion to the substrate. It may be necessary to use a primer, prior to the application of the foam.
2. It is important to use the foam within a temperature controlled environment, the minimum temperature to which the foam can be installed should be no less than +20°C.
3. If the temperature is below +20°C the foam may show signs of slumping and irregular expansion.
4. Cans should not be left in an over-heated environment, temperatures above +50°C or exposed to direct sunlight.
5. Prior to application ensure that the surrounding area is protected, in particular when using the foam in retrofit applications. It may also be necessary to mask and protect the
surrounding area of the cavity, particularly in areas where the compartment may be decorated or furnished.
6. Shake the can for two minutes, until the foam inside becomes liquid. This is essential to ensure the performance of the product. Then attach the adapter or gun to the canister.
7. Fill the cavity from the base of the aperture slowly and build up the layers of the foam, ensuring that the void is filled. Take care not to over-fill the cavity.
8. Allow the foam to cure and using a sharp bladed instrument cut-off the expanded ‘cured’ foam.
9. Ensure that empty cans are disposed of by reference to local regulations.
