Review: Preparation is the key. Follow directions exactly. - Tried many times always with a good result. This product has been around for many decades. Fast and easy to use. Best concrete patch ever. Highly recommended by 50+ year builder.
Review: Worked Great! - I got this to fix a wobbly mailbox post (which seems to be a popular reason). I thought I had ruined things because I got the mix way too watery. I figured I would have to order more and try again, being more careful with the mixing. BUT a couple of hours after I had poured it around the post and set a pole to prop it up straight, it was solid as a rock.

## Questions & Answers

**Q: I want to build a free-standing concrete base ( approx 9" x 7" x 2" thick) for a sculpture. Can I   pour Rockite into a cardboard mold to do this?**
A: I have had a lot of success with Rockite in plastic containers, e.g. cottage cheese container. The Rockite might stick to the cardboard. I would suggest trying a smaller scale version with the cardboard to see how it reacts. If it does stick, you should be able to sand off the small cardboard remnants.

**Q: I have read this product could be used to fill small cracks in your driveway.  Has anyone tried this?**
A: Yes! I used it when we had to to take out some burglar bars. Which left wholes, cracks & splits in the brick ... worked great!!

**Q: can rockite be sanded?**
A: I would say yes if you would try to sand other concrete. I wouldn’t personally

**Q: Can I drill into Rockite?**
A: i'm sure you can drill a hole in it, i don't know if will crumble over time.  i generally use it to anchor bolts
