Thank you for your question. For a 560 sq ft area at 1" deep, ~97 bags of Sakrete 0.5 cu. ft. Step 2 Paver Leveling Sand should be enough to complete your project. Hope that helps and thanks again.
He means 64sq.ft
You can still used open it spread and sprey a little clorine and that will removed the algae and mold.
No is not
I don't know what mason sand is? This is made to go under pavers and I found that a layer of 1/2 inch to 1 inch is very easy to pat down and level with a board. I am working on 2 small projects and it worked very well. These are my first paver projects.
6' x 25' x .25' = 37.5 cubic feet The bag says it's .5 cubic feet 37.5 / .5 = 7.5 You'll need 8 bags.
not my language
Each bag weighs approximately 42 pounds.
I don't recommend using sand as a base when pored on something that decays. Eventually, there will be unsupported gaps between your pool bottom and the sand. The pool will be more susceptible to cracking under the weight of the water. We have a pool.
75 bags of 80 lbs or 100 of 60 lbs
