WHERE CAN SPRAY FOAM BE APPLIED

Spray foam insulation is a wildly diverse product in its features and benefits as well as its very unique ability to be applied to a vast range of substrates. We are going to take a look at a number of various substrates that spray foam can be applied to and what steps should be taken to ensure proper adhesion and performance of the foam insulation. A general for all substrates that one may work with when spraying foam is that they must be clean, dry, and free of grease, oil, loose scale or rust, etc. Another rule to follow when spraying onto a new, unknown substrate is to spray a small 2’ x 2’ test area first, leave to sit overnight, and test for adhesion the next day before continuing to spray.
Alright so now that the basic rules are in place, let us start to take a closer look at all the diverse substrates that spray foam insulation can be used on:
