Questions & Answers

Could this concrete also be used in stepping stone molds?

Could this concrete also be used in stepping stone molds?
Asked by: ebvlb
Yes, but if you are putting mosaic pieces in, you need to work really fast! I was pushing in leaf shapes , and it was difficult to work with as it seemed gravelly.

Asked by: chaplin
You can mix this before hand like my neighbor does and he is happy with the outcome/set. I don't like a lot of extra mess so mix it in the ground (actually just add water to the dry mix that I poured into the application) and have had great results as well. Try it both ways and leave a review.

when using several bags, do I add bag then water until it’s mixed and then add the next bag then water and so forth?

Asked by: Marie
It depends on what type of project you're working on. For example, if you're digging post holes, you can pour the dry concrete around the post, then add water, or you can mix the concrete yourself and add it around the post. Your best bet would be to visit the Quikrete website for the best answer. www.quikrete.com

How many bags for stockade fence 4 x 4 posts 2 ft down 10 posts thanks

Asked by: Fishal
Based on ten 12” diameter holes, each 24” deep, with a 4”x4” post (3.5”x3.5”) would be 37.56 bags. The math that HD Smiles posted is pretty much correct except for the inch to foot conversions are off. There are 144 square inches in one square foot, but there are 1,728 cubic inches in one cubic foot (12x12x12), not 1444. Either way, this is still way too much concrete for a 4” fence post. You don’t need a 12” diameter hole for a 4” post. 8” is plenty. Save yourself the extra digging. It’s a fence, not a bank vault.
