For a 1/2" layer for 80 square feet you will need 8 or 9 bags. It is usual to have an inch of sand beneath paver stones but you have not stated your application. There is a chart on the paver sand bags to help calculate the number of bags you need for your project.
The price is listed on the website or maybe when you get ready to check out. It's not that expensive but it really does work well
FOR ME I WOULD NOT USE PAVER STONE SAND AS IT IS NOT ALL SAND IT HAS SMALL ROCKS THAT WILL MAKE ORANGE SKIN OR WORST LARGE BUMPS THAT COULD PUNCTURE PLASTIS LINERS ...... I WOULD USE PAVESTONE PLAY SAND UNDER MY LINER ... SEE THE PHOTO OF THE PAVER SAND BAG AND YOU CAN SEE THE ROUGHNESS IN THE PICTURE ON FRONT OF THE BAG AS PHOTO 1 SHOWS THE NATURAL PLAY SAND IS BETTER FOR ME AS A BASE IT IS FINER AND NO GRIT PHOTO 2
It can be bought by the pallet in individual bags, we do not sell bulk bags by the ton.
Depends? If you are asking can this be used as the sub base for concrete pavers to rest on--then yes. If you are asking can this be used to pour concrete on top --then not too sure. Perhaps you should contact the concrete company or inquire at Home Depot.
You're probably looking at about 8 cuft, so 16 bags.
I used one bag for every 2 stones (the large size stones 14 x 14???, I don't remember) But you really want to measure the area for the patio, figure about 2-3" under each stone ... some inches are less due to the terrain but you want the stones to be leveled. When you are done, you then must use the perma set or similar to seal the joints, wet it, let it dry, and you are done. The paversand will brush away so put that perma set inbetween each stone. Enjoy.
Also, its listed on the front of the bag.
Slag sand is reactive with water, so no, this is just sand. You're looking for polymeric sand which will harden after moisture is applied.
You figure this out by thinking 2-3" underneath each patio stone. Depends on the size of the stone. You also must use perma set or something similar to 'set' each stone.
