A quick rundown of which concrete mix best suits your needs:
QUIKRETE® Concrete Mix in the yellow bag is a cheap versatile concrete mix that works well for these projects. The big advantage — other than price — is that it’s easier to find in smaller 40- and 60-pound bags, which are easier to carry. If you’re making small, intricate pieces, you can strain out the large pieces of gravel.
QUIKRETE® 5000 Concrete Mix is a commercial-grade blend of stone or gravel, sand, and cement and is specially designed for higher early strength. This is the recommended concrete mix to use because of the high early strength and low price. It’s great for making tables, pavers, stools, and lamps and is typically found in 80-pound bags at Home Depot, but 60-pound bags are also available.
QUIKRETE® Countertop Mix is a super high-performance mix that is worth the price. It has no large pieces of gravel or aggregate, which makes it great for small intricate pieces such as lamps and vases. It’s easy to work with and comes in different colors. Most stores don’t carry it in-stock so call ahead to your local Home Depot to have it ordered for pickup.
