Spray Foam Removal

How difficult is it to remove spray foam under the trailer? Since I have a 19 with the gray water dump valve well under the trailer, I'd like to do the mod to have both black and gray easily accessible. Is there a technique for removing the insulation that works well?

I removed some to replace a broken black tank gate, wasn't hard to remove. It was worse spraying some back on.

I used a razor knife that you can push the blade up on making the blade 4 or so inches long. Also used a sharpened putty knife. The putty knife did most of the job. It came off in chunks, roughly the size of a baseball on down. Took me about 30 minutes to remove what I needed to. I ended up with a 5 gallon bucket full.

I used a 2 part polyurethane foam kit to redo it afterwards but I know some folks have had decent results with the much cheaper can of Great Stuff, or something similar.

I had to remove some to cut the grey tank pipe and add new fitting and grey tank valve . Pretty easy . I used plastic putty knifes to not damage anything hidden under the foam . When I got to the point I could see under foam pieces good , to clean up grey abs I used fine steel wool . I needed to get clean to glue new fitting on grey pipe .
I 'm not worried about replacing the foam I removed . Pat

I just joined the forum, and working on my build sheet. Would either of you go with the spray foam again or leave it clean to work on projects under the escape? Located in Texas, not sure if it is a needed investment?
Thanks
Pat

Is your home insulated? In the winter we insulate to keep the cold out. In the summer we insulate to keep our air conditioned camper cool. With our Casita we once camped on a black tar slab with no trees and our floor heated up.

Recently, there was an Escape for sale that had minimal insulation and single pane windows. We and others were interested until we found out they saved money on their build. It took a while to sell and he lost more on his resale than the windows/insulation would have cost.

Enjoy,

Perry

Put some catnip on the area you want removed and wait for neighborhood kitties to scratch away at it!


I lost some while staying at a friend's during my recent 2 month trip. It was due to at least one of her barn kitties using it as a scratching post.


So, if a cat can do it, so you can.

Definitely going with insulation all around and the windows. Considering the heat more than the freeze after reading. Thanks for your input. Congratulations on your Oct. delivery.

Not only for insulation but to decrease sounds from outside by at least a half a quarter of db's. After removing my fridge I used this spray foam, (Home Depot) to refill backside cavities. I also managed to get some on the tires and the gelcoat outside. Using this stuff I found does require great attention to technique.

The decision to foam or not to foam was a toss up for me, for the obvious reasons, Insulating properties vs ease of maintenance. I got it and 4 years later I really don't know if I made the right choice. I occasionally camp at temps below freezing and find the floor still gets cold requiring carpeting of some sort to sit at the table.

I've had deal with removing it to fix plumbing and had it save the holding tanks from damage by road hazards. If I were to do it again, I'd get the foam.

I think it would help to hear from someone who has a trailer with, and one without the foam, to see what they think.

We have the foam and pretty much sums it up for us. Yes would get the foam again for the protection it offers . (Our grey valve was damaged from something hitting it on the road , that wasn't covered with foam )Pat
