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

I love using this stuff for decorative projects. Does not smell.

home Depot never send me this product within this package. took my money but no product received

Purchased this item to avoid mixing cement on my mailbox replacement…..Got post level and ready to add product, rolled it up per the instructions and video….Then rolled the bag and BOOM it exploded and when everywhere!!! Stained my sidewalk and killed my grass….Barely enough to fill the hole.

It takes more than expressed on package but it is an easy method to get a post set.

Do NOT use this product for flag poles

EXCELLENT STUFF!! Way better than lifting a 50 lb bag of concrete, not to mention it sets in less than 5 minutes! ROCK SOLID!!! I have used this to reset a mailbox and now to resecure a 12 ft privacy fence! I am sure I will find more uses in the future too.

Quick ands easy to use, worked well

It did not do very well we used product accordingly and it did not secure the post. Need to redo using quick crete

Be very careful with this stuff ! It blew up before I could even see think about cutting bag open! I was lucky just got it all over my hands! It is very hot cause of the chemical reaction! Won’t they that again!

This was awesome. Better than cement.

Generally easy to use; easier to use than the instructions make it seem. But, be careful: you may not need the full bag, but if you do pour the full bag, you'll get a mound of polyurethane foam protruding from the hole you're filling. Also, if you find yourself in that situation and have vegetation you care about nearby, you may want to put a throwaway plastic barrier between the vegetation and the polyurethane - I used the outer plastic bag the product came in to protect my plant when I saw the expansion was likely to reach the plant. I used a saw with a blade not for wood or metal to cut the excess off.

Watched you tube and used one bag it foamed fast barely got in hole. Used 2nd bag and barely cut the corner it exploded all over my face and covered my eyes. Rushed to urgent care who took me to local hospital and was transferred to OHSU in Portland. In trauma didn't know if I'd see again. The cat scan showed I closed my eyes just in time. Had it in my nose,hair and front teeth. Also first degree burns on my face. Now I'm facing ambulance bill and two hospitals. Please do not buy. I don't know yet what my legal options are.

I didn't use this stuff. It might work in the short term but I had my doubts about the long term. I used Quikrete Fast Setting cement. Again, don't use this Use the regular stuff.

This product is amazing, I put in a flag pole and it cut my time in half. It’s expensive but want to save time this is the product you want to use.

Works great, but have everything ready. Once you mix the pouches you've got to be ready to use it

The product was very easy to use and is strong enough to hold up my mailbox. The problem I have with it is that as it cured it pulled away from my mailbox post so now rain and water will be trapped against my wood post which is what I was trying to avoid so it would not root the post.

First time user. Very easy to mix and pour with the easy to understand instructions. Very little liquid in hole to start but within a minute it was rising and expanding. I had 2 inches of excess and used a razor blade to cut away. Felt very sturdy within 15 minutes.

Well, I bought 2 kits, the first one I could not get to break the mid seal but I did get the corner seal to squirt all over the concrete deck. The second I emptied each part into a 1 gallon milk jug and stirred with a paint stick and worked just fine.

easy product to use.

This worked perfectly and post set almost immediately. No issues here!

Utilized by product directions. Does not support the pressure on the post. Only used one time, so possibly a soil issue. Would test one post and let cure for several days before utilizing on a large project.

The fence post supports worked perfectly to reinforce the leaning fence we had. We placed 6 supports in total. The Fence seems really strong and secure now. The offset of the post support really helps with not interfering with the existing post cement. The sika foam worked great. Let’s see how many years or months the sika foam holds up. If you’re looking for an easy solution to a leaning fence I would recommend these two Products. My only criticism would be that I wish the post support was a little longer to support the existing post a little higher up, otherwise great product.

Easy to use, follow instructions, and it works great!

I love this product!! You can mix and pour and within a couple of hours you can continue your project.
