50 lb. Fast Set Concrete Mix

I needed it to set a umbrella clothes line in a big container so I could have it on my upstairs deck. I was a little confused on how much water to use. I like to have instructions like so may quarts water to bag. But it was not that clear. I called the company and a associate told me exactly how much water for a bag. I had 3 bags worked great. PS I'm a 70 year old woman. If I can use it anyone can. Only needed nephew to carry bags upstairs.

This concrete is great for setting post-holes; I needed something that was easy to mix and set quickly. It is also very strong when it cures. Once mixed with water, the concrete sets in about 30 minutes. I used this concrete when the ground and air were in the mid-40 degree range so I had a little extra time before it set. If it is warmer, you will have less time. You can mix this concrete between 40 and 90 degrees and minimum thickness is 2" for strength. I dug my post holes with an 8" auger (8" wide hole) and, with the post inserted, found I needed one 50 lbs bag per foot in depth of the hole. Most holes were 2 feet deep and needed 2 bags per hole. This mix can also be used for footings, concrete repair and slabs/sidewalks. I also like the 50 lbs. weight of the bag, it is much more manageable to carry around than an 80 lbs. bag. Mixing is easy, I set and braced my post all plumb, filled the hole with 1/3 water (I used warm water since it was cold out) then I poured in mix until the water rose the top of the hole. I then used a thin piece of scrap wood and pushed it through the mix until water was absorbed. I then added more concrete and mixed until the hole was full. The only problem I ran into was as the hole filled, the last few inches were hard to mix as water was pouring away from the hole. I had to add a little concrete and water until it was mixed right. I then used a trowel to slope the concrete up towards the post on all four sides (so water doesn't puddle around the post and rot it faster). Within 30 minutes after I finished, the mix was hard. I then placed a trash bag around the concrete to aid in curing and help keep it warm as night time temps dropped below freezing. I then waited 24-48 hours to put the fence on. Of note, since it reached freezing at night, I kept my concrete bags inside where it was warm which helps aid in curing.

Price is right - gives you enough work time before setting - I usually add cement - nice finish - occasional bag w clumps but usually fine

very nice to handle and is very fast to set, yes i will buy it again

I used this to set our mailbox, it worked great and was easier to use than I expected!

Used it to set fence posts. It worked great.

Just as stated. Sets quick. Very helpful for small projects that you have no help on to offset allot of bracing and waiting

Excellent product - fastest way to secure posts for a project with the kids.

I love this stuff! It's so easy to just pour the mix into a hole for a project, add water and poke it with a stick to make sure it's mixed up, then repeat in layers. I purchased one bag but I should have gotten 2 bags for the long posts I was putting up for a vertical garden. I didn't fill the holes up all the way but it's been up since May (this is December) and it hasn't leaned at all, and the pocket garden is filled with soil and very heavy. I always let it set up overnight just to be sure it's fully cured before I put stress on it, so I've never had an issue with it when I put a post up for a bird house or other project.

easy to use I poured water in the hole added sakrete i had too much water so i went back to store and got another bag then added it and mixed light post still standing and we had a serious noreaster on Sunday
