Hartline 10006 Rockite Cement 15 Min 5 Lb, No Size, White, 80 Ounce

It was easily mixed to the consistancy I needed to support the ground sleeve for my clothesline, dried quickly as well...i could visibly see it absorbing the water after 20 minutes. It was rock hard in an hour but i waited several hours before i covered it with gravel and soil removed from the hole i dug. The price was great as was the quality and ease of use. I will definitely be ordering it again for future projects.

Well,this doesn't go far. I just order my 5th one for a 3ft X 10ft walkway. Using gloves works better than a bare hand. Definitely a learning experience. I'm using white on my walkway to the house.

Our new house has a front porch with an iron railing that had the bottom leg originally set in mortar which had deteriorated. The railing was wobbly. I researched what quick concrete to use to set a post or railing and came upon Rocket. I cleaned the hole in the brick that housed the railing leg, mixed up a plastic cup of the Rocket to a consistency that could be poured. I anchored the railing leg into the proper position and poured the Rocket into the hole up to the top. After 30 minutes, the railing as fixed and immovable. It's now been a few weeks and the Rocket is obviously completely cured. That railing will never budge or come out. This is very good stuff if setting a post is your project.

When they talk about drying fast, they aren't kidding. Mixing it is like trying to get pancake batter just right. Tip: use a lot less water. I tried two different mixtures, one with lots of water and the other with very little. The low water batch was malleable and easy to apply. I could adjust and push it where needed. The second batch I added way too much water. I was churning a soupy mix with a baking spatula for 7-8 minutes. It still dries in the prescribed time no matter what though. In a couple minutes it went from the consistency of melted ice cream, to pancake batter, to silly putty, to solid rock. Forget a putty knife, it was drying so fast I had to just grab and apply with my hand in a mad panic. As far as stress is concerned, I think where it fails is bending and shearing stress. It can survive compression and tension well. Grab a piece with both hands and bend; it will snap like spaghetti. That is of course in the uncured state, right after it hardens. Letting it cure, greatly improves the quality. Also, it doesn't cover much. I seriously underestimated how much I would need. I bought one bag, but I am going to have to buy at least 3 more bags to complete the sealing project I had going on. Overall I am satisfied, but learned a hard set of lessons from the first couple batches.

Used it to fill some small gaps in a concrete deck & concrete steps mostly on the sides. Mixed up very small batches no bigger than what fit in the palm of my hand. Tuff to get the exact consistency for it to be moldable so it wouldn't just sag out of the openings to be sealed. First little batch went hard on me before I got it applied. Had to throw that out & the plastic cup it hardened in. It hardens in just seconds once it reaches the moment in time to harden. I smoothed the side surfaces by wearing a vinyl glove that I then dipped my gloved hand into water. The wet glove made the surface easy to smooth but even glove could not have too much water on it or concrete would go soft and sag out. Doing a horizontal surface was very easy. Just mix it up slightly pourable then spoon into the opening to be sealed, level it and it's tendency to sag into place makes it self leveling to a perfect smooth surface.

This was used for a shower floor repair - it worked excellent!!The area was about 18" square and I used the entire boxWas easy to mix and use - and you have to move fast once it's mixedI added some small pebbles to this after I laid it down to match the existing floor - it worked great!Highly recommend it

I bought this because I was looking for a smaller container of cement for a crafting project. It does not disappoint. It actually sets in 15 minutes or less and is super strong. I won't buy anything else moving forward. The finish is super smooth, also.

I think this would be good for fixing an anchor point but you would need to make sure its dry. I purchased the product to fix a cracked bird bath but if it gets water on it you can see a slow dissolve even if you let it cure. But it was very easy to mix and apply and did go on smooth so if you can keep it dry it should be excellent.
