RV Remodel | Closed Cell Spray Foam Insulation

The biggest goal we needed to accomplish during the Minnesota edition of our RV remodel was to spray foam insulate the interior. If we weren’t able to do that before we made the jump to Tennessee, then we wouldn’t be able to live in the RV. Because brr.

 

Since the spray foam chemicals needed to be at 70 degrees in order to work properly, both Chad and I were afraid we might not be able to insulate before moving. The freezing temperatures in MN weren’t exactly conducive to the process.

 

Thankfully, family came to our rescue. We were able to park in the temperature-controlled bay of a mechanic shop, which meant we could spray foam as soon as we were able.

 

Which wasn’t as soon as we thought. Every time we went in to work on the RV with the intention of spray foaming, other things cropped up that needed our attention. This was anything from replacing newly found rotten studs, to covering small holes and gaps we had overlooked or forgotten about. Ugh.

 

If you’re in the market for an RV, here is a little advice: don’t buy a 30 year old RV, then decide to gut and remodel it less than a month before you’re moving multiple states away. Things will crop up, over and over again, that need to be taken care of before progress on the remodel can be made.

 

This will happen no matter how good of shape you think the RV is in. I guarantee it. 30 years is a long time for an RV to be around without its structure dilapidating in some way.

 

Just take my (our) word for it.

 

Once all the prep work was finally, finally done, Chad was able to spray foam. And we both breathed huge, exaggerated sighs of relief. Hooray, we wouldn’t freeze.

 

Check out the video below to witness the long-awaited process!

As you can see, we are definitely first-time spray foamers, and Chad has some tips for other first-timers who might be reading this:

 

1.) Before you begin, tape and plastic off anything you don’t want foam on. If you don’t, you’ll spend a lot of time scraping insulation off of places it shouldn’t have gone—like the windows and floor.

 

2.) As you’re spraying each section of the walls, make sure to fill in the edges where the studs meet the wall first, then spray the rest of the section. There ended up being quite a few gaps in our insulation where Chad didn’t do that.

 

3.) Instead of the tiny utility knife you see me scraping excess foam off with in the video, grab a vibrating multi-tool. I had to use ours on and off because my weak little arms couldn’t hold it up for very long. But it made the job go much faster!

 

So that’s that. This post marks the end of our RV remodel, Minnesota edition (with the exception of a clip or two in our next video). Hopefully, Snowpocalypse 2016 will blow over soon, and we will be able to continue making our shell of an RV into a home. We’re starting to go stir-crazy down here!
