Customer Questions & Answers

Is the can and it's tube re-sealable?

Asked by: Anonymous
Yes, after a fashion (for great stuff in general). Take a 3-1/4 in nail (12d) and slide it about half way into the tube. With the can UPRIGHT, slightly pressurize the tube (this re-liquifies the product, you'll see the foam re-liquify in the tube). Later, when you want to use it again, to remove the nail, squeeze the tube (where it sticks to the nail) here and there with a pair of pliers to break the seal, and then the nail should pull right out, grab onto the head of the nail with the pliers and pull/twist. It'll keep a month, maybe two, I've gotten more than a dozen uses out of single cans across the span of days this way. If it doesn't dispense properly, it's been too long - just pitch it and start a new can.

CAN IT BE USE TO REPAIR CRACKING PLASTIC WICKER

I HAVE A PLASTIC OUTSIDE WICKER LOVE SEAT THAT IS CRACKING FROM WEATHER WEAR AND I DO NOT WANT TO THROW IT AWAY. IT HAS HOLES AND PATCHES MISSING. CAN GREAT STUFF FOAM BE USED FOR CLOSING THE HOLES AND OTHER CRACKS THAT ARE IN THE LOVESEAT. BASICALLY CAN IT FEEL THE MISSING AREAS IN.
Asked by: VONDA
It would fill the holes and cracks (if you could get the nozzle inside the material as this expands outward) but would in no way improve the integrity of the piece. Basically it will not help the issue nor make it better. This product is designed to fill in voids with the intention of preventing air flow and has no real structural value.

16 oz. Big Gap Filler Insulating Foam Sealant is rated 4.0 out of 5 by 240.
Rated 4 out of 5 by from It works, It really works Love this "STUFF" works great and repairs literally last for years. I've used it to fill in large gaps where stucco has crumbled on the outside of my house. Keeps out weather, moisture, critters etc. until I can get to a more permanent repair. Easy and effective temporary or permanent repair. Only draw back is the nozzle. The newest renovation is a sliding cap on the end of the nozzle which restricts the flow. It caused so much pressure in the length of the nozzle that it snapped the entire nozzle right off the connection on top of the can. Look for the open ended nozzle. Store will exchange with no problem. Clean up is messy but if you clean the nozzle and straw well, you can get a 2nd and 3rd use from the can. Definitely wear latex gloves. This stuff is made to stick tight and your fingers are no exception.

Rated 5 out of 5 by from Works Great!! I bought this product to fill a crack outside between my fireplace and siding where bees decided to make a nest. This morning the bees were unable to get in, so hopefully they will go away. My only recommendation is to wear gloves while using this. I got a lot of it on my hands, and it became an unwashable sticky paste that I had to use nailpolish remover to get off. It got rid of the stickiness, but I still have caked on insulation on my fingers this morning that will eventually come off. Also, make sure you clean out the plastic application tube. After it dried out, I was able to use a shishkabob stick and toothpicks to push it out.

Rated 4 out of 5 by from Very similar to regular Great Stuff I needed to fill a gap of over 1 inch wide and 14-foot long. One can was enough, though I had anticipated it would be too much. As it turned out, the Big Gap filler was not substantially different than the regular Great Stuff in that it didn't expand as much as I expected. Therefore, I had to double back and re-fill many remaining gaps. In the end, it worked for my application, but its performance did not match the description on the can. In the future, I'll just buy regular Great Stuff because it seems to be more dense (i.e., smaller bubbles in the foam) when cured. By the way, I've seen complaints about GreatStuff regarding how messy it is when you try to work it/shape it after applying it. GreatStuff is not caulk and should never be touched after application. Trim any excess only after it is fully cured (note: the inside can remain sticky after the outside is firm to the touch, so be patient).

Rated 4 out of 5 by from Seems the same as regular gap filler This filler was on-sale but still a dollar higher than the reg foam for the same size. I used both types interchangeably and couldn't tell the difference. Both filled large gaps with the same ease. Material seemed the same once dry. I can't recommend it over the reg version for large gaps.

Rated 5 out of 5 by from Great product We bought this because we have a leak in the roof and there was a storm coming. No water came in! Great product, it worked to stall the repair. Piece of advice, use gloves, it can get everywhere!

Rated 5 out of 5 by from Great Stuff spray in foam. The product does what it claims it should do and gets into the smallest areas to make a seal against drafts & insulates as the company claims - glad we chose this product for our project!
