      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!

              Best fence post mix
              This is the BEST stuff to use for fencing, installed a vinyl fence and it is STRONG.

              Shrinks after expanding!
              The product looks like it will set up nicely as it expands. However, after 24hrs of cure time the foam appears to settle and actually shrinks! This defeats the whole purpose of using an expanding foam! Wasted money and time only to have 4x4 posts covered in a foam base that wobbles back and forth. I used Fast2K applied in the gaps of this junk and it set up PERFECTLY. Recommend Fast2K over this product. No comparison.

                lasted 1 week
                I followed the instructions by the book. Some people here say theirs lasted months or even a full year. Mine became soft after 1 week.

                Hi Adrian, we're sorry to hear this. Project longevity varies from customer to customer, however after only a week, there may have been other factors that effected the overall application. Please feel free to reach out to us with any questions. SikaRetail

                  Worked great. Used two bags
                  My post hole was big due to digging out a very large concrete anchor. I never want to dig out concrete again. I purchased two bags of Sika. It was easy to use, set up quickly and it helped me complete my mailbox post project in one day. I used one bag at the base of the hole and a second bag after tamping dirt into a smaller rectangle. Most people will only need one bag with a narrower hole. My neighbors were impressed with the post’s stability utilizing the Sika mix. I definitely recommend this product.
