Concrete mix for structural repairs

Sakrete 120021 is a gray concrete mix supplied in a 50 lb pail for building curbs, steps, patios, sidewalks, floors and downspout troughs. It is formulated for setting posts and general concrete construction where a paintable finish is required. The product meets ASTM C387 and is restricted by California Proposition 65 for reproductive harm.

Check temperature range and substrate before use

Application is limited to ambient temperatures between 40 and 80 degrees F and requires a minimum thickness of 2 in on concrete surfaces. Mixing ratio varies by job so verify the correct proportion for your specific repair. The pail contains no applicator tools and the mix must be used within the stated working window.

Full strength develops over 28 days

Working time is 1 day after mixing, allowing placement and finishing before initial set. Full cure time reaches 28 days, meaning the material continues to gain strength long after the surface appears hard. Load-bearing elements should not be stressed until the cure period is complete.

Questions about this item

Does the 50 lb pail include any tools or additives, or must they be purchased separately?

The pail contains only the gray concrete mix; water and standard mixing tools are required but not included.

When should I choose this 50 lb size versus a different bag weight for a project?

Choose the 50 lb pail when the job calls for roughly that amount of material; larger or smaller bags suit different volumes.

What does the 28 day full cure time mean for when the finished slab can carry weight?

The mix reaches full design strength after 28 days; light foot traffic is possible after the 1 day working window.
