If you notice the links under “Materials” and “Tools,” it’s because I linked to Amazon searches for those things, in case you want to do this project but need to load up a cart.
- 4 x 8ft Foam Boards (Polyisocyanurate or Polystyrene)
- You’ll probably need to go to your local home store for these as I don’t find them online for a reasonable price.
- Spray foam insulation – might as well buy a case of cans at least
- 3/8″ flexible plastic tubing for pushing over the tip of your foam gun, so you can get to the hard-to-reach nooks and crannies.
- Hopefully a 25′ roll will do it.
- Work gloves that are tight enough to work in, but you don’t mind ruining with spray foam
- Work pants, long sleeve shirt, shoes, hat, etc.
- DON’T GET SPRAY FOAM ON YOUR SKIN OR HAIR, it’s a pain.
- Foam WILL GET EVERYWHERE, especially on your body. It’s weird stuff, it’s on the move, and has a mind of its own.
- Drop cloth or plastic
- If you have a concrete floor and don’t care about foam falling on it, fine. But it WILL fall on your floor, and it DOES NOT come out of carpet.
- Dust masks
- Especially for the cleaning part.
- Ear plugs
- You may be logging a lot of loud shop vac time.
- Shop Vac
- Spray foam Gun
- I finally broke down and bought one of those $50 spray foam insulation guns, WORTH EVERY PENNY.
- I left a can on the gun and turned the knob closed–9 months later I scraped off the old stuff from the tip with a utility knife, shook the whole thing for a while, opened the valve, and pulled the trigger. It came spraying right out. Now I’m a believer–spray foam on tap FOR EVERYONE! Not just for billionaires anymore!!!
- Reciprocating saw, with PVC, metal, or multipurpose blade
- Tape measure
- Utility knife
- Chalk line, long level, yardstick, or other straight-line device or straight-edge tool
- Shims (can be made from scrap foam)
- Why shims? Sometimes you want to prop up the blanks and create a gap so you can spray under them while having both hands full working the gun and articulating the flexible tube. Especially true on the long runs on the ends of the basement/crawl space. You can pull them out later, or not.
- I also used regular door jamb shims as a tool to pry up some of the blanks, so think about sticking some of them on your step stool tray, or maybe a paint scraper…
- Work lamps and/or head light
- The basement may seem lit well enough, but when you’re poking your head into a bay and blocking all the light, that when you’re glad for point lighting.
- Step ladder (Cosco brand folding “Work Platforms” highly recommended, again: WORTH EVERY PENNY, and will serve you in many other jobs to come.)
