Can I use "Great Stuff" on holes?

[Vicr]

I've been in construction for 35 years and Great Stuff is widely used. To seal around your power cord wrap your cord with electrical tape an inch or two above and below where you are going to seal (this will make removing Great Stuff easier from the cord) use "Door and Window" (minimum expansion) and wear disposable gloves.

Indeed! Brass wool instead of steel wool.

Not that brand but the same basic product is used in the construction of many RV's to seal holes so the answer is yes. however as someone else said, use caution if you have to remove it.

A better plan (in my opinion) is foam rubber (really flexible plastic foam) I get foam pads that insluate some stuff I buy that is shipped cold, you can also buy the stuff, like pillows are made of, in craft stores,

I cut a strip the proper width then wrep it around the cord and "Stuff" the portal, provides an easily removed seal and works well.

I wouldn't use products that can burn or metallic products like steel wool. Simply pack the area with Fiberglas insulation and then pull or vacuum it out when needed.

I do not know how your rig is built. But everyone I have had has a long box under something where the first 25’ or so of the power cord is stored. What you want to do is find that box inside the rig. Find the OTHER END of the power cord coming out of the box. THAT is where you want to use the Great Stuff. Critters going up the external cord will find that inside hole and the gamae is over. If they cannot get out of the box they leave or make a nest you pull out the next time you need 20’ of power cord. Now that is assuming the power cord box is made like any good box. Not a sloppy box. A sloppy box would require filling in the sloppy holes with Great Stuff also.


I have not seen it but I understand there is a Great Shuff that critters do not like to chew thru out there.


On my, new to me, current rig. The PO had sealed as many utility compartments as he could reach. The power cord box. The box under the dinnet cushion were all the electrical stuff is. The box under the bed where the water tank and pump are complitley sealed around all the electrical and water pipes going into or out of that box. All water pipe runs through walls or floor are sealed as near as I have found.


I hope this is good food for thought. One last thing is all of my LP items with exterior access have part of a dog flea coller in them laying on the bottom of the compartment. Found out about that on this site way before 2010. Never had a spider or wasp nest in them since.

I use Great stuff to plug gaps but I do not plan on removing it. It is tough stuff and as mentioned, it sticks to your hands rather well.

There is indeed a version of GS that is pest resistant. Called Great Stuff Pestblock. Grey colored foam in a green can.

What a great idea I will try this

[tuffr2]

I would not use it because I am too messy with it. Even with plastic gloves I would probably get some on my arm, if I remember, even after you stop that darn stuff keeps oozing out of the nozzle.

You would never be able to clean it up. After a few years that stuff turns to dust also.

Are you trying to keep critters out or the cold out. Either way, I would not use that stuff. Been there, did not like it.

It’s called Great Stuff Pestblock. I use the regular Stuff so I can’t say how well the Pestblock works, but I know it’s carried at Lowe’s.

That's your opinion. Construction professionals and DYI'ers have no problems with it and it does not turn to dust. It is widely used in the construction industry and it is a specified product by some engineers. It does what it is supposed to do sealing holes and air gaps and there are several types including the "Door and Window" which has minimal expansion.

It's great stuff, but remember that some of it expands more than you think and if it gets away from you it is hard to clean off. Does seal very well. Plan the job and dispense carefully!

You can buy painter's gloves that go almost to your elbow. If you're worried about getting this stuff on your arms these are good for that. I hate getting paint and epoxy glue on me, but this stuff is even worse. I just painted 525' of pipe fence, and those gloves were good to have.
