Ratings & Reviews for Sika Mix-In-The-Bag Expanding Polyurethane Post-Setting Foam Fast Setting 33 -fl oz Repair accessory

Expanding foam.

First time I’ve used and it works fine.

Mailbox post filler

The lumber associate recommended using this foam mix to secure my mailbox post and it worked well. Good recommendation thanks. It was a lot easier than mixing concrete.

Don't leave in the sun

Dont let this stuff get hot before you use it. We left it in the sun for while we were getting ready to use it. It exploded on my sister and husband. It is very messy to.get off.

Bad product.

While it was cold out the product did not mix as it should have. After mixing one bag without success I set the rest inside to warm up (had picked them up the same day) for a few hours before trying again. However, they did not mix together or expand properly. These bags have an expiration date on them and I wonder if they say for too long before I bought them, or if Lowes improperly stored them.

One and Done!

The product is easy to use and very applicable for a mailbox post. Instead of buying a bag of quick-mix and only using a quarter of the bag - this product is one and done, and you can cut away the excess - great product, and I'll use it again when needed.

Foam expands and hardens quickly!

Worked perfectly for mail box!

Does the job perfectly as expected without hassle.

Very easy to do when following instructions great.

Super fast - made the job quick and easy

Loved that I only needed one bag and the ease of use

Erases heavy labor mixing cement

This is a huge time saver, and muscle saver! It makes setting fence posts so easy to install. One bag of this weighs maybe 5 pounds and replaced the heavy mess of mixing two 50 lb bags of cement! I set 6 posts with this. Excellent product!

Great, quick and easy of use

Its quick no mess mixing concrete a bit pricier than concrete but it compenses whit easy use and it hardens in minutes so its great option messy free

Quick and easy

Worked great for our shade sail posts in the backyard.

Works as advertised

Not used product before but seem in videos. Worked as advertised, learned you benefit from having size of hole at least as large as directions. Firmly holds 12’fence post 3’ deep hole.
