10001 Rockite Expansion Cement 15 Min 1 Lb

A neighbor hit my mailbox/light post outside and it was tilting halfway over, filling it in with dirt was not enough to keep it upright.I choose this instead of concrete because it seemed less mess and hassle. It was, it's super easy to use and mix, and works perfect. My post wont budge now.I got a one gallon plastic water bottle to use as my mixing bowl, just cut the top part off. You need a throw away stirrer or spoon. You can make this as thick or runny as you want, there is no instructions.So add the powder first and slowly mix in water until desired consistency.I put 4 wooden wedges around the post and hammered them tight. Then I made half of the powder mix to be slightly runny but not too watery. I poured over the wedges and into the gaps. Let sit a few hours to harden. Then I mixed the other half and repeated the steps. I figured it was best to not have a really really deep pool that might soak into the ground before it all hardened.Now I will fill with dirt and hope no one else hits it :)

Love this stuff , has multiple uses , is rock hard in no time , light Grey color, self levels,

I purchased this to secure a post to hang my new gate. This stuff gets rock-hard and fast. Very easy to use and sets solid in minutes. Very pleased with the results. Would buy again.

The product is a good and it does the job. The color turns out to be a light gray and smooth but I’d like a rough for patching and anchoring it’s perfect. Great for little jobs. A little bit goes a long way. From the reviews I see most people put too much water into the mix which should be only tablespoon at a time. Remember you have 15 minutes before it starts to bond, so you do have enough time to play around and clean up while it’s beginning to dry. But it’s very important to start cleaning up immediately in your work area. OK to walk on after 30 minutes

Fast drying cement easy to use and rock solid after that.

Very disappointing. Bought this product to fix a small gap (6" deep x1" wide)in my yard and the mailbox post causing a wiggle. Bought this product thinking the expansion aspect of the product would be prefect to resolve. Followed directions as stated. Let it set it for an hour, box stated 15 minutes to realize the benefit.....no good. Strongly advise to skip this product.

This product would be good for an intricate hole or design in the ground because it is so thin. And it breaks easily if you are pouring only a thin coating.

I received this product and used it already. This is a great product! I'm glad I saw this product.I only needed a little bit to do what I needed to do and it was just perfect!!! Thank you!!
