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

Just as Advertised

Word just as advertised. I ca hang my full weight off my mailbox. Very easy to do.

It is very fast acting

Easy to use. A much cheaper alternative to concrete

Love this product!

I used this expanding post-setting foam for the post supports for my greenhouse floor and it worked wonderfully. The instructions were very clear and concise, and mixing and pouring was very easy. I highly recommend this product.

it makes things really easy

It works very will and easy to use. The instructions are simple.

Easy and effective!

This worked perfectly when we needed to replace a few old fence posts in the backyard fence and didn't want to mess with the mess and hassle of mixing concrete.

Good for specific applications

It's a simple product to use. It is not a long term solution to fence posts if you have a run between posts greater than 4-6 feet. It does not stand up to high winds very well and tends to fail quickly in areas with lots of roots. Overall this is not a good replacement for concrete and long term fencing and post setting but good for short term applications and certain post repair jobs.

Did not work well

Did not fill a small hole 8" with 4x4 27" deep as stated in instructions. The product was room temperature in my house before mixing. It did not say anything about outdoor temperature use. It was about 45⁰. It swelled up to the top on only 2 sides causing pole to get out of perpendicular.

Worked really well and completed the job quickly.

This worked really well and completed the job quickly as needed.

Recommend

This stuff is really great as a substitute for cement. It doesn’t make a mess everywhere.

Newer and Easier Way to mount a post

Mailbox post got busted during a snowstorm. Used this stuff in freezing temps and it worked great. Easier to work with than concrete. Holds well. I have used before and will use again

Will buy again.

Good instructions and easy to use. Wear rubber gloves and be prepared to use it quick.

Quick and eastt

Easy to use. Very simple directions.

First time user.

Good alternative to bagged concrete mix, sets fast and holds really well. The amount of product needed per instructions for hole diameter and depth is short of what it actually creates when setting.

Limited uses

Might work fine for a mailbox post but not worth a darn for fence post. I tried it on both sides and wish I had just used cement.

Works and is easier than mixing concrete

Worked as expected, secured mailbox post, probably not great for a heavy fence post. Have to follow directions and give it a few minutes for the chemical reaction to happen but it will. Sets in about 2 hours and he can be back filled

Good Stuff

Worked as described! A lot easier than concrete!
