Spray Sealant for pipes on underbelly.

[JohnD]

After dropping my underbelly, I need to reseal the areas around the pipe exit points. Anybody have any recommended products to use for this application. I'm referring to the gray spray foam that hardens.

I used Great Stuff Pestblock when I resealed the coroplast.

If you decide to try it, take note that this is messy material. Disposable gloves and skin/eye protection is highly recommended. It is difficult if not impossible to reuse the attached sprayer, so consider the can a "one time use" item. In other words, be ready to use as much of the contents as possible in a short time-frame. If the material hardens in the sprayer it's done...

If some of the material does spill onto the concrete or area under the trailer just let the foam harden and then it's easy to remove.

The original sealant that GD uses is made by boring-smith its called Power Hold RV Black Foam. Comes in a 24oz can and requires a foam gun. You can fin it in their web page https://boringsmith.com/p/convenienc...t-p8hhjq69b94a

I used this same spray foam and while the foam I purchased was not black, I liked the critter repellant factor. It was used everywhere there was an opening to seal off the rig.

Great Stuff also makes a black foam sealant. https://www.greatstuff.dupont.com/pr...ose-black.html usually available at Home Depot.

Rob,

I did buy the black at home depot at one time but they replaced it all with the PestBlock in a tan color. Most times I shop there I rarely find exactly what I'm after.

Thanks everybody for your input. I agree that the critter repellent aspect is a nice feature.
