Installation Instructions
Preparation of the Substrate:
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. It may be
necessary to use a primer, prior to the application of the foam.
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.
If the temperature is below 20°C the foam may show signs of
slumping and irregular expansion.
Cans should not be left in an over-heated environment, temperatures
above 50°C or exposed to direct sunlight.
Prior application of the foam, 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 maybe decorated
or furnished.
Shake the can thoroughly, until the foam inside becomes liquid. Then
attach the adapter or gun to the canister. 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.
Allow the foam to cure and using a sharp bladed instrument cut-off the
expanded‘cured’ foam.
Ensure that empty cans are disposed of by reference to local
regulations.
