Kraken Bond Fence Post Mix | Concrete Alternative and Replacement for Fence - Deck - Mailbox - Anchor - Basketball Post | Fast and Strong Expanding Composite Footing Compound | 1 Post Setting Kit

In 1992 I got a degree in Chemistry. For the past 32 years I’ve worked (without an accident) in labs dealing with acrylics, acrylates, polyurethanes, nitrocellulose, and alkyds. THANK GOD for that training. I got this product today and mixed it exactly as described on the label (see the pic…add part A to part B and mix for 20 seconds). After 5 seconds of shaking, I felt the exothermic reaction starting. After 20 seconds it was really hot. I know it was 20 seconds, because I used my iPhone timer - again, that “chemical geek” in me.Now, I’m ready to pour it. Only due to my chemical lab background did I not lose an eye! I opened the bottle AWAY from me (the average John Q Public might not have). Still, it didn’t matter. This stuff EXPLODED out. It sprayed 6-8 feet away from me AND backward all over my shirt and shorts (and face and hair)…see that pic. Had I opened this up TOWARD me, like a typical person would do, it would have coated my face and ended up in my eyes…i.e., hospital trip!I was able to pour some of it (the part that wasn’t solidified) down the hole. The rest solidified all over the container, the concrete and my picnic table (6 feet way).I would STRONGLY request an inquiry from the company to confirm that this particular batch of product ( lot numbers shown in the pics) was in or out of spec. Secondly, I demand a compensation of $62 USD - $42 for my work polo, and $20 for my shorts. I also would like an apology, and maybe even a change to the mixing time. I’m not asking for anything regarding the time and effort (and shaving off my goatee) that it took to remove this crap from my legs, face, arms, legs and hair.PS - glycol ether DB (aka Brake Fluid #3) works better than gasoline or acetone to remove this.Lastly, I’m not asking for a refund in the product, since, yes, what little I could get into the hole seemed to work fine. 4 out of 5 stars for physical performance. 0 out of 5 stars for your instructions. (If you change the instructions to “Mix for 10 seconds”, it would have been a WHOLE different story).

worked as stated. did exactly what it said it would do. lil pricey compared to concrete but no clean up & easy to use

A plus...

It solidifies. But it activates so quickly that it’s all over the driveway rather than around the mailbox

This stuff is not upto the task of setting posts of ANY kind. I followed instructions (so simple I doubt you can mess up) - to “the letter”. You DO have to watch outside temps!Its like the 2-part foam used in packing boxes and also the marine industry. And it has its uses!But it has no real holding power. After digging the hole - I used 4 pcs of 1/2” rebar and a 10” section of 2” PVC pipe as the pole holder “sleeve” (with 1 pc of rebar also in its center). After mixing the parts, I dumped it in and used my level to assure it was straight.After expansion, I inserted the mailbox (on its pole) into the PVC sleeve - to be certain that the setup was still plumb. I held it in place until the foam was set. I then re-filled the surrounding area again with mulch.To complete the task, I inserted 2 stainless #12 screws through the PVC - threading into the mailbox pole, to leep it from rotating in the sleeve, holding it so it is “clocked” straight.Results were not totally “solid”. It is like you would expect if you just used a can of foam-in insulation. If anything hits or brushes up against that mailbox - it will very likely break loose.Hopefully our mail carrier is easy-goin when the mail is delivered!I cannot imagine someone using this to set fence posts - @$20 a post!!!BTW - I also put up a split rail fence. A friend used his tractor with an auger to bore the post holes for me. I drove 3 pcs rebar in each hole.To do this, he first drilled a hole straight - then I set in the post, dumped in dry Sackcrete, (filled the hole to the ground level) and we set in the rails - and moved on to the next post. We had marker paint and string lines to keep straight the fence line.The fence is so tight, so immovable, kids climb on it all the time and you cannot move either of those posts. The rain and ground moisture set the concrete in no time. Its been there 10 years now - and its still like new.Don’t waste your money on this foam stuff. $20 can buy you more than enough rebar and cement to set a few posts. YES - its a PITA to go get those 40 lbs bags at the local hardware rip joint. But the results are 100% worry free and solid.That is my two cents.
