CUSTOMER REVIEWS

Rated 4.5 out of 5 by 26 reviewers.
Rated 5 out of 5 by Worked as indicated on bag I purchased this product after my stockade fence fell during a storm. The previous owner of my property set the poles in sand so of course that didn't withstand much wind. I didn't want this to be a major project spanning multiple days so I jumped at the possibility of quick set no mix concrete. The day I used this product it was 34 degrees outside so I did as directed and added hot water in the quantity indicated. After putting tools away ,I took a shower and changed clothes. In that amount of time (approx 45 mins) it had set solid .. I'm very happy with this product for the use described, note however that the finish was rocky since there was no need to smooth it for a finished look since I covered it with dirt after photo but for setting poles the red bag product works great.

Rated 5 out of 5 by 5 Stars for me, too I buy this all the time for setting poles, and for whatever else I need to set fast. Here is a tip. We (almost) always mix it, but that's just the way we always have done it... We pour in some water to 1/2 of the hole depth, pour in dry cement from one 50# bag. Then we mix it with a tire tool or large pry bar or stick. We add water if needed. Now in most cases, this will be MORE THAN PLENTY to set the pole in about 15 minutes. So on top of the quick-setting mix out of the red bag, we CHEAP OUT and add in some regular Sackrete to finish the hole. We often will mix 25# of the red bag mix in the bottom, and 40# to 80# of the regular mix, which is about a bag and a half per hole. You can mix directly in the hole with the standard Sackrete, just pour and stir. This is a few bucks cheaper, and pretty effective. The bottom 12 inches of the poles are rock hard in 15 minutes, and the top can be neatly troweled after an hour or so. no more stupid braces on every pole! Works great for fencing. You actually can tweak the poles a little bit while the red bag is curing and before the regular concrete is placed, but you better be fast with a plumb stick and pinch bar. You can't tweak much once the entire hole is full. Also, this can be mixed with just about any other concrete product to make it cure faster. Use a little of this to accelerate concrete in the winter. May 16, 2013
Rated 5 out of 5 by Quick and easy I purchased a few bags of Quikcrete fast settling concrete from Home Depot, to install a couple 4x4 posts in my yard over the weekend. I had never used this product before so when I saw it in the store, I jumped at the chance to avoid mixing cement in a wheelbarrow with a shovel. The product worked exactly as described. After putting gravel in the hole and leveling the post, I dumped 3 bags in per hole, as the guide on the package recommended. I added roughly 3 gallons of water (1 gallon per bag) and walked away. After a couple hours the top of the cement had hardened. After 4 hours, the post was solid and I finished my project the same day. This project was supposed to take a couple weekends to complete but thanks to Quikrete, I finished in a day. April 8, 2013
Rated 5 out of 5 by Works Great This stuff works great. My boyfriend and I put a privacy fence in our back yard. Once the holes where dug for the posts everything went so smooth and quick. Just poured in the Quickrete and added water. Within no time it set and the posts where ready to go. It went so fast. We would get a few set and then do a few others and while those set we would start putting up the panels. It was quick, smooth easy and hassle free. My boyfriend and I did the entire yard in one day and never argued once. That right there is priceless!!! May 5, 2010
Rated 5 out of 5 by Best quick-setting concrete ever! I had read all the reviews of the Quikrete fast-setting concrete but had never used it. I was setting posts for an aluminum fence in our front yard. It worked exactly as stated on the bag. I poured the concrete into the hole around the post, added 1 gallon of water and once the water was absorbed, I covered it with dirt. Within 30 minutes I was able to set the next post without any movement in the previous one. Would highly recommend for this type of job. August 13, 2013
