![]() Once the mortar is ready-and once you’ve dampened the surface of the footing-lay down a 1-inch bed of mortar along the chalk lines you snapped in Step 1. Continue mixing until you obtain a consistency that can be easily troweled. After adding both ingredients to a wheelbarrow or mixing bin, mix them using either a mixing hoe or an electric drill with a paddle-type mixing attachment. There are only two ingredients-mortar mix and water the trick is to strike the appropriate ratio between the two. In preparing the mortar, pay close attention to the instructions printed on the package. Forgiving to those who are not experts in masonry projects, the QUIKRETE® preblended mix remains workable for a long period of time, with no sacrifice of the high-bond strength that yields a successful project. For cinder-block walls (and brick walls too), choose QUIKRETE® Mason Mix Type S. Then, once you have removed the blocks from the footing, you are ready to begin in earnest. Once you are satisfied with the dry fit of your base run, snap a chalk line on either side of the blocks to serve as a reference. A 3/8-inch-thick plywood scrap can help you make each gap precise and uniform. ![]() As a result, as you’re figuring out the number of blocks you’ll need for the base course, it’s essential to accommodate for the space to be filled in with mortar. So, though the standard block may be billed as 8″ x 8″ x 16″, it actually measures 7-5/8″ x 7-5/8″ x 15-5/8″. You may already know that cinder blocks are sold in nominal dimensions that assume the presence of, and take into account, a 3/8-inch mortar joint. These gaps are stand-ins for the 3/8-inch mortar joints that will appear in the finished wall (not only between each block, but also between each course). As you place the blocks, remember to leave a 3/8-inch gap between each one. The goal here is simple: You’re determining the number of blocks necessary for the desired wall size. Start by simply laying out the cinder blocks for the first course of your wall. If you need help understanding the relevant building codes in your municipality, be sure to contact a contractor, inspector, or code enforcement specialist. ![]() As there are varying definitions of what constitutes a building code-compliant footing, the following instructions assume that an inspection-ready foundation already exists. But no matter your skill level or experience, these step-by-step instructions from QUIKRETE® can help you transform a pile of cinder blocks into an attractive, lasting element of your hardscape.īefore reading any further, however, it’s critical to note that every block wall, structural or not, requires a solid footing. Of all the skills involved, working with mortar may be the most challenging, as doing so calls for some technique and finesse. That said, with careful planning the process can be straightforward, and the project is certainly within reach-provided you have the strength to lift and place 30-pound cinder blocks. If the average do-it-yourself project takes only part of a day and minimal heavy lifting, then, well, this isn’t your average job.
