Customer Questions & Answers

can I buy one bag? and how much?

Asked by: Starwolf
We bought one bag of this perlite at our local Home Depot (City of Industry, CA), so it WAS available by the bag at one time. Apparently Home Depot decided to discontinue selling it in single-bag quantities. Too's an excellent product.

How many 8x8x16 concrete block will a bag fill

Asked by: David
A 2 cft bag will fill 8 blocks of that size. Typically, perlite is also used at different thicknesses on at least one side of the blocks when building a wall. The amount of perlite for that can be calculated by multiplying the total square feet of wall times the thickness of perlite to be used.

Customer Reviews

2 cu. ft. Coarse Grade Perlite (32-Bags) is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Too bad they stopped selling individual bags This is a great product. We bought a single bag of this at our local Home Depot. Now that we want to buy more, we get the bad news that Home Depot is only selling it by the pallet, and only online, and on top of that they're out of stock. Very disappointing.
