Customer Reviews for Sika 33 fl. oz. Sika PostFix Fence Post Mix, Mix-In-The-Bag Expanding Foam for Supporting Non-Structural Posts, Mailbox, Sign

The bag ripped while following instructions to break the seal had liquid everywhere. Wish I had just bought the quikrete which now I have to go back and get 35 minute round trip. Save time and energy just buy the quikrete!

It makes installing a fence by yourself much easier than concrete.

The boards I bought were in very good condition.

Product took some experience to get right. Expansion was more than expected and did not fill to hole evenly but was much easier to work with than cement and took less time.

Did exactly as instructed. Poured in, waited for it to expand and it did not stick to the wood. pole could hardly stand on its own after 10 minutes of holding it.

I bought this to use for the mailbox post. Kept rolling up the bag as demonstrated by the video. It wouldn’t burst. Had to almost stomp it and the top of the bag burst and spilled out. Was able to mix the little bit left in the bag. It works great if you can get it to burst correctly. Sets well and quick.

Love this stuff. Great product when you need post set time to be less than 5 minutes

Bag of concrete is $5. If you have no water maybe it’s worth it. I will stick to concrete.

The bags were hard to find since they were covered with concrete dust from a spill that must have happened months ago. Last time I bought these, the bags were also filthy. However, they are packaged in a plastic bag, so the inside was intact. They perform well for a low fence post and are much easier to manage than 50 lb sacks of concrete. The stuff expands so make sure your post is securely held in place while the material cures.

Very easy to use and works great!

Best fix it product . Easy peezie . I used this to install my fence fix . In less than an hour I dug the hole , installed the fix fence and went on with my day .

I tried this product for the first time. Breaking the seal was the most difficult part of using the product. I ended up pouring the first part into the hole then breaking the seal and mixing the two parts while in the ground. Everything turned out okay. I will use this product again knowing that I must work harder to break the seal between the two parts before pouring the contents into the ground.

Should have read the reviews before I ran out to purchase!!! Followed the instructions and at 23 seconds the bag exploded! All over me, my project and everything around me. So disappointed!! Thank goodness I turned my head to avoid my face/eyes. But it took a good hour of scrubbing my skin raw and cutting some hair to get MOST of it off. Took skin right off my neck and hairline. Have to replace everything that was ruined. Not worth it...get the cement even though it seems less convenient

Super easy to use . Helped with my mailbox post!

way better than the back breaking time to use concrete

Made setting 29 fence posts less than a one day project. Started framing and attaching pickets the same day.

Seal did not burst to blend the product. Instead the top exploded and splash liquid all over me.

Was used for metal fence posts since they didn’t have sakrete qwik Crete. Simple to use. Set in no time.
