Always good stuff or perspectives to be aware of. But, after almost 60 years in design/construction, I have finally recognized there is always something new you haven't experienced before.
Thanks for sharing!
Thanks Mike! Just did a hot roof with a Froth-Pak.... Can I add that to your list of lessons learned. Not worth it! I happen to be starting a rig in a month I hope and will do the rest then. But for anyone else out there thinking I only have 600 sq/ft to do, I'll just use a froth pak. Stop. Hire a pro, it is well worth your dollars. The mess, the inconsistency, the conditions needing to be right, and the mixxing tip always plugging up. I know I won't ever do one again, but I hope it helps someone else avoid that mistake as well.
Really loving the channel! Thanks Mike!!!
We had a closed cell spray done on the crawl space under cabin. HOLY cow how nice it is, keeps the moisture out from migration into the living space. We had the joist bays done full 2" and faces, AND cheeks of every board lightly coated for moisture excusivity.
Another informative video Mike, nicely done. Definitely critical information about hidden problems. Not something the average homeowner would even think about and most builders don't even care about as it is not "their problem". I hate that attitude in a builder since every one is supposed to be working for me the homeowner!!
18 years in insulation. 15th year of installing spray foam. We do not tape, unless it's a finished surface, otherwise we scrape. 98% closed cell. We have gotten to a point that we can keep scraping to a minimal. No prep crew and many times we work solo. From additions to large scale commercial. A lot goes into spray foam that doesn't get realized and you have to keep your head on a swivel all the time. Nice video.
I agree personally I would never use tape and I get very little on the studs I rarely have to do any shaving with open cell. Those walls are looked down there flush to the stud with at least 70% of the skin left on it we're not perfect lol
It is interesting to see the issues you have to figure for up north. I'm in Austin Texas, so humidity and dew points are big. Wind isn't usually very high, but if the windows are open there is a chance that there is a layer of dew on everything and that can shut a day down. We also don't spray nearly as much close cell down hear so the labor to clean studs is way lower. But on occasion we will do a house in close cell, so the tape trick is very helpful.
Really good advice. Virtually with all things, preparation is 80% of the work if you want a nice job done.
Very true!
Priceless education ... was a great day discovering your channel and can't say enough how thorough your methods and techniques are .... prep is everything and that forethought shows.
Awesome, thank you!
Always learning something from your channel, thanks for the content!
Glad to hear it!
Hi host, your tip , of putting boxing tape on the side of the 2x4 is a great one. More tips please.
Thank you for the video!
I remember climbing around on the skeleton on this turret that had the same ceiling and some of the boat bottom great room, and the bottom of the turret was a spiral staircase to a sublevel, accessing alot of the fireblocking ended up being just climbing studs. The turret was scary, had to put on a fall arrest harness with no anchor while site manager was around
In windy situations with open window holes I would put either heavy cardboard or wood panels over the holes and fasten on. Any kind of expendable plywood or OSB will do nicely.
Excellent information! I’m considering this on my home. I want to remove the cement board shingles to expose the bay and spray closed cell foam. It’s hot here in Las Vegas and I’m just trying to keep the house cooler.
Fabulous tip about taping over the wood. Prep work is everything. I’ve never done this before, do you think this is something the average homeowner can do or not? Thanks.
With it taking so long for windows to be delivered, they are leaving the windows and doors sheathed and spray foaming first down here on the NC Coast.
That’s pretty smart we had that problem in California a couple months back
Well said!
Thank you, have a job in our attic coming up. Installer stated 1"closed cell then 12" of blow in. I think he said 57 r value (Maine). Sound legitimate? Ceiling below it tin and zero insulation ( attic is vented)
Awesome video!
Glad you enjoyed it
Here's another simple yet important learning tip: Not everyone can afford spray foam. Yes, it's the best. Yes, we want to be the heros and help everyone step into the 21st century and save energy. However, throwing in prep time for free will always bite you. Ignoring the time expense and mental strain on the employees that are dealing with unique and difficult builds (because your guys are awesome and can handle it) is a sure way to lose production and turn profit margins into flatlines or red digits. Last simple reminder...your employees don't want to be there as much as you want them there. Treat them well, be kind and understanding, and they will go out of thier way to make you more money and grow your reputation.
Thanks Mike, great subject. 🔥
Agreed. I find clients that volunteer to do the prep come back asking us to do it...
How wide is the packing tape you are using to cover the stud edges? At a certain point will the thickness of the overspray compromise the integrity of the tape? If it folds over the edge it seems like it would be hard to remove.
I've been spraying 20 plus years now and it's hard to Admit when you're wrong I started off at a medium sized company in central Florida using the original problem (probler) gun we didn't have techs to call or have the conveniences we have these days so I learned the hard way. The previous commenterwas right saying a lot goes into it that isn't realized I always welcome anyone that criticizes my work because I do a lot of free lancing to come out and see what happens and what goes on if the equipment isn't correct And you don't have exactly what you need. I've done some very large projecyss 3 federal courthouses a couple of military bases a couple of hospitals Is several fruit packing warehouses and I can't count how many residential houses. I used to own my own company and had 2 rigs and I plan on getting back there again but for right now I travel around spraying for numerous companies
i can tell you guys do superb work, quality. you don't get that from high production companies.
Yeah, like I believe that you guys have made a mistake. :)
I have learned so much. Thank you!
Glad to hear it!
Nice video! Is it okay to do 2” of ccsp directly to roof deck then do ocsp directly over it to the desired r-value (R-38 in my case)? I’m in climate zone 5, will have an ERV, and unvented attic spaces obviously.
Not unless one of the suppliers has done the proper vapor drive analysis to confirm that will work.
You need sign offs for these things otherwise you are guessing.
Had closed cell sprayed directly to my metal. The sprayer used fiberglass batts in my eaves with no vaper barrier. Should I worry about the metal sweating and the batts holding that water in the soffits?
For a homeowner doing this. What is the best caulking to use the seams.
Where there is a will, there is a way.😊 If you pin the wheels on and apply the breaks then you can use the braces to hold the one end up while you pur the other end on the braces.then add 2 planks,or 3 to safest. Then put your next 2 end pieces up on the plnaks and prop your braces up where you can reach them. Don't forget the pins and connectors. You get the rest.😂
Posted on Friday the 13th... Golly, that's a great day to talk about things going wrong!
Or blessed. 13 in the bible means promise...
Were locared in Florida. What is a good spray foam supplier?
Is a commercial van that is 7’ tall, 13’ long, 7’ wide large enough to outfit a spf rig?
Hello, great channel. I had my attic sealed with closed cell spray foam. Question, my spray foam contactor shoved fiberglass insulation into the cavity where my roof soffits are then spray foamed over it. The spray foam isn't covering the top plate that my 2nd story ceiling joists are sitting on. Should I complain? I would have never noticed if I hadn't taken down the ceilings in my bedroom for renovations.
I don't know without seeing it. Go watch the non vented roof video. part 2 and 3 show many details you can glean from.
@mattd9171 very common practice. What matters is that the foam ties into the top plate of wall and ceiling.
I’m getting ready to build in the western part of Virginia. I went with poured concrete walls for the basement. Any idea which foam is the best for that type of construction? And anyone know of a reputable spray foam company that services Augusta County Virginia? Also, very good points in this video that I will adhere to in my construction process. Thank you.
Closed cell SPF, we do basements all the time. You will have to vet your contractor, I do not know anyone in Virginia.
What’s the blue caulking called?
Question: I have a 30x30 metal shop that is set to be insulated with open cell spray foam in a few weeks. Sometimes when it rains I have leaks here or there. Is open cell a bad idea?
That's like tying a sponge to a leaky tap. Only an expensive one. Even closed cell which is better will only help for so long. You really should fix the roof. It will slowly fill the open cell and peel it off once it gets heavy enough... closed cell it will last bit longer but it will get behind the closed cell and work its way down and into your walls. Your sprayer should tell you this and if its wet it should fail moisture test anyway. Goodluck
We are building our house. Should we hire a spray foam company or is it worth it to buy a DIY spray kit?
Pro install. You don't know anything about this.
Why not use an AP EX Gun Extension for some of those hard to access places?
You need to get close in order to "place" the foam where it needs to go. A large wide pattern just makes a mess.
First pass in should be tight and right..
@@SprayJones Agree with that, but I cant see the AP EX Gun Extension is doing that, but I'm not sure.
You ever do foam roofing with elastomeric coatings?
No not externally
@@SprayJones Ok, just curious. Is getting more popular down here on commercial roofing.
