Given its strength, ease of use, and aesthetic potential, you might think concrete would be pricey, but think again! Ready-to-mix bags of Quikrete are an affordable building supply. Plus, if you make your own molds and do your own pouring, you can achieve custom creations at a low budget. While Quikrete offers a range of mixes that vary in cure time and additives as well as in aggregate sizes that produce different densities and textures, all are easy on the wallet. For example, an 80-pound bag of Quikrete Countertop Mix, which makes 0.6 cubic feet of wet concrete, will run you about $20. A DIYer with some concrete experience can pour a standard 8-foot-long, 2-inch-thick countertop using just four and a half bags of Countertop Mix. So, for about $100 and the cost of framing materials, steel reinforcement, and optional dye, you can have a chic new concrete countertop. In fact, with all the money you've saved by choosing concrete over, say, stone for your countertop, you could probably spring for professional help with the pouring.
