Wear respirator and eye protection

Spray foam insulation can be dangerous to breathe. Wear a respirator and eye protection while working with spray foam insulation.

  • Long sleeves, pants and closed-toe shoes are recommended as well.

Create a dampened cloth to clean edges

When cleaning up the edges, use a damp cloth. Water is your friend when it comes to cutting foam insulation, but you don’t want it to get everywhere—this can create mildew and make your house feel damp. The best way to prevent this is by using a damp cloth or paper towel instead of wetting down the entire area where you’re working with spray foam insulation. When it comes time for cleanup, use something like a dry shop towel or newspaper that absorbs moisture without dripping water everywhere and making an even bigger mess than what’s already there!

Choose the right blade

  • A utility knife is the most common tool used to cut foam insulation. It’s a long, rectangular blade with a handle on each end of the rectangle.
  • A razor blade is another option for cutting spray foam insulation, but it can be difficult to get clean lines and straight edges when you’re working with this type of knife.
  • If you choose to use a box cutter, remember that these kinds of blades are duller than other types of utility knives and require more pressure when cutting foam.

Score along the line

Score the foam along the line that you want to cut. Score the foam at least 2 inches away from the edge of your material. Scoring is a technique used to cut insulation, and it involves making several cuts with a utility knife in an alternating pattern across an area of closed cell foam insulation. This will allow you to easily split your insulation into smaller pieces after scoring it with a utility knife. Score along this line in two or three places, depending on how thick your spray foam is, and then remove each piece as needed in order to reach what’s underneath it.

If you’re cutting curved lines, make sure that when you put your blade down onto one side of where you’d like for it to go through that there aren’t any air pockets between themselves or anything else sticking out inside that could get caught up underneath there when going back over those same areas again later (like when trying). If there are any other problems with how deep they’ve gone under some parts being too thin compared against others being too thick – which could cause cracks during installation – then try pushing harder while gently pulling back against them until they start making progress towards cutting through instead of just keeping hitting upon resistance every time they try moving forward again (which might lead them getting stuck altogether).

Cut with a knife Spray Foam Insulation Contractor Coon Rapids MN

Cutting spray foam insulation with a utility knife is the easiest way to do it. Simply follow along the line you want to cut and don’t push down on the blade, keeping it at right angles to the surface of your foam insulation. This will ensure that you get clean edges and no puckered holes in your finished product.

If you’re using a utility knife, make sure that it’s sharpened before starting work so that you can get through all of those layers without struggling too much or accidentally cutting yourself on any rough edges.

Remove excess foam with an oscillating saw

  • Use an oscillating saw.
  • Make sure you’re wearing a respirator, eye protection and protective clothing.
  • Cut straight through the spray foam without pressing down on the blade or using too much pressure; otherwise, it will melt and stick to itself instead of cutting smoothly.

Use the right tools and techniques to cut spray foam insulation.

When cutting spray foam, use the right tools and techniques. Follow these steps:

  • Wear a respirator and eye protection.
  • Cut along the seam line using a dampened cloth to clean away excess foam as you go.
  • Use the right blade for each job (see [link] below).
  • Score along one side of your cut line with a utility knife or electric razor, then break off excess by folding back on itself. The dry-cut method is preferable if you’re trying to avoid messes, but it does take longer than scoring first with an electric razor/knife combo tool like [this one]. If there’s an electrical outlet nearby, consider using an oscillating saw instead of duct tape to hold down your work piece; this way, you can cut through it quickly without having to worry about getting stuck in place yourself!


Spray foam insulation is a great way to insulate your home and keep it warm in the winter. Unfortunately, it’s not always easy to cut with a utility knife. If you want to make sure that the job goes smoothly, use the right tools and techniques. First off, wear protective gear like respirator masks and eye protection so that you don’t breathe in any of those nasty chemicals or get hurt by flying pieces of material. Next up is choosing what kind of blade for cutting: do you need something sharp enough for cutting through metal? Or does using an oscillating saw make more sense? Finally there are some other options too, such as scoring along the line before ripping out large pieces via hand tool or sawing through slowly from each side until meeting in middle!
