Black Foam source

[doughere]

I'm looking for a source of black foam that is for large gaps. I can find Great Stuff white in large gap filling, and Great Stuff in black 3/4 gap filling. I can't find anything in black for large gaps. Anyone know a source?

Thanks,
Doug

Try DOW # 283064. Its sold under different names, most notable Great Stuff Insulating Pond Spray Foam Sealer.

The stuff used in most RVs is made by Boring-Smith. To use it, you’ll need a gun. I bought a cheap one on eBay and it worked perfectly. You’ll also need a can of gun cleaner. The stuff worked well, and hopefully the gun and foam will work again in the future. Probably $50 in it due to Boring-Smith’s shipping charge, but it was a flawless repair when I installed the rear hitch on my 5er.

The major difference between Great Stuff White and Black is the black dye. I suspect they are otherwise interchangeable. Just so you know.

But read the labels to be sure.

True story: Company I know a bit about makes a product that is BLUE in color. one of the parts is a common washer.. Like you'd use under the head of a bolt or the nut on the other end. It is blue.

Customer ask if they could send him one. Company spokesperson told him to hop down to the local hardware and get one "But those are not blue" Well the OEM one was not blue till we painted it either"

They are painted after assembly.

Consider using A/C preformed tubing cover It comes in large sises and is black. It is easy to cut or form with your fingers. UV resistant. Available at Home Depot or Lowes.

The black pond stuff can usually be found at landscape supply stores. It does have a tendency to turn yellow when exposed to UV light.

They dont seem to have the "big gap" stuff in black anymore, just "cream".
That's too bad.

Beat me to it. That's the stuff to use.

For large gaps, you have to use Gorilla tape to "fill" in the larger area and hold the foam until it dries. Once it dries you can remove the Gorilla tape. As others pointed out, just spray paint the yellow black once it dries. Unless you pay hundreds of dollars for a spray applicator system, you cannot get the easier results the Factories get with their large expanding foam applicators coming from a 55 gallon drum. Doug

I do like Dan, or do more than one application to fill a big gap

In a pinch once I simply spray painted the white stuff black as I had both laying around.

Great Stuff makes a Black Foam for 1 Inch Gaps.

How big of a gap do you need to fill?
