it states that you don't have to mix this before hand...…..but can I do it anyways or would it screw up the texture or whatnot
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

I have a project where I actually want water to slowly seep through. Is this product water permeable after it sets? If not, is there a way to make behave this way?
Asked by: Nathan
After this Quikrete sets, it is just like concrete. It will absorb moisture but would not permeate water in a seeping fashion. I would guess you would need a compacted sand mixture to create a seeping effect.
