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:

Always remember the basics preparation: substrates must be clean, dry, and free of grease, oil, loose scale or rust, etc. Don’t forget if you have concerns start by spraying a small test area on the substrate to check for adhesion. If you still have questions after spraying your adhesion test don’t hesitate to call Paratus and ask some of our experts for help and advice.

    Could you please advise, what the expenditure would be for the tools, and material that I would need to do a 28′ 48′ barn 10′ walls,
    and two 40′ X12′ new wall construction by 2×6″ wall construction.
    I was told that I should buy 1 barrel each of A and B would yield 4000sq’ Appreciate your advice.
    Respectfully Eric

      Well Eric it is always best to have a couple local contractors quote the job for you because pricing can change dramatically from one area of the country to the next. The 4000 sq ft number you got is fairly accurate number if you are talking about closed-cell spray foam. Closed-cell spray foam will yield about 4000 to 4500 board feet (a 12″ x 12″ x 1″ thick) of coverage if properly applied.
