DIY Spray Foam Insulation - What You Need to know Before You Start

I Used the Tiger Foam Quick Cure closed cell foam Formula – 600 Board Foot Spray Foam Insulation Kit.
The key to this project is prep. Make sure you have everything you need to start and finish the job before you pull the trigger. I suggest watching this video and a few others before purchasing the material for your project. Hope this video was helpful and thanks for watching...Jon

I did my friends mom house it was single story with a 4 ft crawl space built in ther 50s. The hardwood floors were freezing cold in the winter 1x6 subfloor so the cold air was filtering through. We used a spray foam and got roughly 3 " coverage but what a difference it made. It wasn't easy in the space and quite a mess not cheap but that floor needed a vapor barrier

I looked into similar products to spray foam the rim joist in my home, same as you would require two sets. I was able to find a local spray company that did the work for the same price. Actually about $50 cheaper, plus they removed the existing insulation and sprayed about 6-8 inches deep. Same price and the experts did the work, no brainer. Took them about two hours to complete.

I have started using a product called polynor, I purchased it via ebay from Poland as its not available in the UK. The product is brilliant and has saved me replacing a 120 year old slate roof.

Excellent idea with plywood box and space heater, hats off!

I love spray foam insulation. There are so many pros to it against the cost. It’s great for your structure; keeps moisture, noise and insects away; closes up ALL holes whereas even Tyvek membrane can’t; holds temperature stable.
I’m not a professional. But after buying a property with a basement that had humidity issues I ripped down several walls and sprayed (bought 2 sets of 600sf off of eBay) the heck out of ‘em. No more damp smells or wet walls. I believe, it’s cheaper than digging out around the perimeter of basement and waterproofing and all.
As Jon said in the video, you must prepare everything for the job to start and finish without a break longer than 30 seconds. Respirator mask is a must, as the fumes are carcinogenic. If planning to spray inside a living space, no other person/animal must be present until at least an hour after the job is finished and space is aired out.
If by accident the foam falls on clothes or shoes you can clean it with help of lacquer thinner. Acetone or nail polish remover can help while it’s still curing.

Getting ready to do my woodworking shop this week. Thanks for the tips on keeping the tanks warm.

Excellent video! I've looked everywhere for information about closed cell insulation and this is the best video out of everything I've come across.

I sprayed my entire crawlspace and it went pretty well. The trick is to be ready to do the entire job in one go. Warming tanks is a must. I bought my tanks off of ebay which was way cheaper than any other option and had free shipping. I don't think the brand of spray foam makes much difference just make sure you get closed cell foam. It's a very rewarding DIY job.

I priced out the tanks vs a company in my area, and North Pole Insulation out of Whitehouse, NJ was cheaper to hire to do the work and bring their own foam with a foam truck than it was for me to buy the tanks, even with coupons, etc. The large companies buy in such bulk that it was nearly the same price, but of course professional installation comes with a guarantee, etc.

Like all projects, we all overlook the importance of prep work sometimes. Great tips. DD

I had my shop spray foam insulated (closed cell) last year and it is great. My mini split hardly runs even in the winter (Ohio) and the shop is always comfortable - 72 in the summer and 62 in the winter. It wasn't cheap but it was worth it.

Tiger Foamed a crawl space addition a couple of months ago. Our house had an addition put on by a previous owner and as it turns out, they did no insulation in it (we live in Canada!) and so the front 5' of the foyer and one bedroom were very cold in the winter. Managed to squeeze under (sent my wife in) and in her cute little Tyvek suit, we got the rim joists and stem walls all nicely coated out. It is very good for hard to seal areas, like rim joists or truss ends. I recommend it highly where sealing up an area is critical, and aren't most areas of your house critical? Yep. If you do need a large area insulated, call the pros.

Jon, thanks for making the effort to capture this on video. Given the limited time you could leave a tip dormant, it was obviously 'one more thing' and so much appreciated. Possible suggestion: you demo'd the way you heat your shop several years ago along with the typical winter results. At some point, you may want to reference that link for those who are newer to the channel. Good luck - steady wins the race.

JFI, Lacquer thinner will usually clean any foam out of the tip if you get plugged. It's pretty useful to clean floors, shoes, but it will dry the natural oils out of anything you use it on, including your hands. Also it finds the smallest cut and burns like crazy.
Thanks for posting! It's great to see you actually doing the spray.
One other thing, I found a small unit that you can plug a heater in, and it is a digital thermostat. It will work on heat or cool, and I think it cost about $30.00. It's was designed to plug into a wall socket, and then plug your heater in. It will heat until it reaches the pre set temp.
Again, thank you!
Smiles!

I agree with video here. Prep work is key, cover your stuff, you only have ~30s before spray foam cures in the tip. I'm doing the same project for the same reason - I have a hip roof construction and it's basically impossible to vent so I'm using spray foam for an unvented roof.

[kurtzimmerman]

well done jon. I'm a firm believer in spray foam insulation. always gives you a complete envelope to stop infiltration from the elements. thanks for another great video!

[MillerHighlands]

Thanks for the informative video. I dont think people realize just how much time goes into these videos. I purchased a Hoodie of yours to help support you. Best wishes in 2022.

[MRrwmac]

Jon, I was curious about what was involved and cost. Thank you, you answered all my questions! I’ll stick with traditional based on cost.

[lindacabral]

thank you for sharing your valuable information, much appreciated !

[fredblair]

good job much cleaner than a lot of so called pros

[TheMortician]

Also noticed if when you spray dont spray it like paint hold trigger and zigzag without the break at the end of each left to right right to left etc doing this youll use less product waste from tip drip and less mess just IMO helped me a lot
