Very Dangerous!
This product is extremely dangerous and should not be on the market. I followed instructions exactly but the moment I started mixing the two products together the bag immediately grew very hot and within ten second it had exploded all over everything- the driveway, tools, bushes, the roadway and me. I never had a chance to tear off the seal before the bag turned into a mini heat bomb. Be very aware when buying the product.

    Great stuff
    I’ve now used this stuff on different posts around my home, some over two years ago, and I’m now confident in using this versus concrete. Just this weekend I used it for a short run of fence (see pic) and it’s working great. While it is quite expensive, it’s so easy to use that I don’t mind the price. I will continue to use it in the future!

      Warning!!!
      This stuff will definitely explode on you. The instructions do not clearly explain the hazard. Heat may reduce time to expansion as it had been sitting in the back of my truck in the sun for a few minutrs, but there is no warning on the package. I had to go to the hospital. Even though i had goggles on, it got in one eye, on eyebrow and went up my nose and in my mouth. ER doctor removed expanded pieces from my nose and now my eyebrow and eyelashes are nearly gone. . It was very painful. Left message for company to call me back to find out how to remove from hair, eyebrows and eyelashes. Water will not remove. Company never called me back. Poison control had no information for ER.

        Won’t last
        I thought why not, in my head I knew it wouldn’t last. I’ve seen the foam buoys that rot apart. Well it lasted almost 4 years, had I used the bag of concrete at half the price I wouldn’t be spending my beautiful Saturday digging out the post to re set it in “longer lasting” old fashioned concrete

          I watched the videos and read instructions before using this product. The one part we struggled with was getting the internal seal to pop to mix the two solutions together. It didn’t foam up right away, so I used a stick to mix up the solution in the hole. It eventually started foaming up around the mailbox post. It looked like a mushroom cloud! Cutting it apart to remove the excess was easily done with a hand saw and chisel. I recommend for a mailbox post.

          Burst in my face
          I’ve used many of these packs before but today while rolling to mix the bag burst and part A sprayed in my face. Fortunately it washed off my arms and face but my coat is ruined. I’ll never try it again as the consequences of the bag failing are too dire.

            The bag exploded
            DO NOT BUY GHIS. I mixed it up for 30 seconds just like directions, grabbed the bag and was going to walk three steps to open it and pour it and it exploded all over me. They owe me new clothes and shoes.

                Buyer and user beware
                I’m limited to 500 letters on this review so sorry you get this version. If you need a clean, permanent, and professional job DO NOT use this product. I might have received the one bag that had a bad spot in the seal but that’s all it took to never want to use it again. Thankfully Homedepot retuned my money. Now I now get to try and see how to remove the residue off my concrete patio and everything else it touched when the bag split open. Looks like I’m not the only one either, beware!!

                  Excellent product! 1 bag filled and set a fence post in a matter of minutes. After setup overnight, feels as strong as concrete!
