Landscaping foam

[Meyer Jordan]

I have a couple cans of black waterfall foam that are expired. Think its safe to try and use? Never been opened.

Probably won't work. All of the pressure in the can has likely dissipated. Which is the problem that I mostly have with the less expensive foam. Entirely too many cans are 'Duds'.

I hate those "duds!" I got home with some once [the HD kind] and didn't realize until I got ready to use it that the "straw" was missing from the side of the can! Now I make sure to check for that!

@haver79, you could always try a can, just be ready to use it all.

I had around 15 cans expired by three years, only one was a dud. I would try them.

hint if you are going to use a lot of cans get one of the guns that attach to spray the foam out ,it saves your fingers and because the nozzle is longer and hard it is easier to direct it where you want it to go

Understand completely! Just glad to have you back!

Welcome back @sissy ! Happy to see you!

And I second that - we bought the gun for applying the spray foam and it works great. Plus you don't have to use the whole can - as long as you clean the applicator you can store the rest of the unused can for later.

As for "expired" cans I would totally test them - you'll know right off the bat if the can is bad.

A question on this stuff. Is it safe to use the foam between a rock and the liner? If you want it to come off, does it come off the liner easily (for repositioning something)?

Yes, to getting it off the liner, but no to getting it off the rock.

Rocks are more easily replaceable.

Not at all familiar with that brand.

How about using cement, is it safe? coz these foam fillers are not available here.

Have you ever used this foam stuff (like Great Stuff in the can)? Once you open a can and start to use it, you have to use it all as it doesn't "keep" like caulk and such will. Unless someone knows something I don't know about it, that is.....

I use a can over and over if I don't use the whole can. Wouldn't use on a pond, but great to fill cracks in the house....and to build reptile hides

They do have soy based foam so wonder if that is safe
