Watch the video tutorial to learn how to pour a patio, sidewalk, or other outdoor flooring with Quikrete.

An outdoor paradise is even more inviting when you can deck it out with outdoor kitchens, fire pits, benches, hot tubs, and other elements—though the extra weight of these sorts of furnishings could benefit from a concrete patio will add up. The commercial-grade blend of cement, stone or gravel, and sand is specially formulated to reach a compressive strength of 1, psi in 24 hours and 5, psi within a month.

A concrete that strong can even handle vehicle traffic, so you can be sure entertaining family and friends on your backyard patio will be no problem. Are you replacing a fence, mailbox, or lamppost, or installing a swing set or basketball hoop for the kids? Setting the posts for these common outdoor structures in concrete makes for sturdier, safer, and more stable structures in the long run.

These components are proportioned at the cement plant under controlled conditions to assure product consistency. Table 1 is a general guide for selection of mortar type.

Other factors, such as type and absorption of masonry unit, climate and exposure, applicable building codes, and engineering requirements should also be considered. The addition of hydrated lime or any other materials to a masonry cement mortar at the job site is not required or recommended.

All water should be clean and free from organic material and deleterious amounts of dissolved acids, alkalies and salts. Since Masonry Cement color is laboratory controlled and Masonry Cement offers the simplicity of the one bag system of batching, it is easier to achieve consistent color cement for a prefect appearance in the finished job.

Machine mixing should be used whenever possible. First, with mixer running, add most of the water and half the sand. Next, add the Masonry Cement and the rest of the sand.

After one minute of continuous mixing, slowly add the rest of the water. Mixing should continue for at least three minutes; extending mixing up to five minutes improves mortar. Masonry joints should be tooled at the same degree of stiffness and moisture. If joints are tooled too early, excess water will be drawn to the surface, producing lighter joints.
