Sakrete 65305535 Fast Setting Concrete Mix 50 Lb

Product Description

The SAKRETE OF NORTH AMERICA 65305535 is a pre-blended, fast setting concrete mix formulated for setting posts, poles, and performing high-strength repairs on existing concrete surfaces. It combines Portland cement with washed, graded sand and gravel, along with special additives that accelerate cure time. The mix sets in 30 minutes, enabling same-day use without waiting for a full overnight cure. No mixing tools are required — the dry mix is poured directly into the hole, then water is added on top. This product meets ASTM Specification C387, confirming its consistency and compressive strength for structural applications. Licensed contractors, landscapers, and experienced DIYers alike rely on it for fast-turnaround installations.

This concrete mix is well suited for residential and light commercial applications where speed matters. Primary uses include setting fence posts, mailbox posts, deck posts, sign poles, and similar vertical members in soil. It also serves as a repair material for damaged concrete flatwork and edges where a high-strength patch is needed quickly. The 50-pound bag size is practical for single-post jobs or small repair tasks, and the pre-blended formulation eliminates the need to proportion separate materials on site.

Installation Notes

Installation typically falls within the scope of general contractors, landscapers, or experienced tradespeople working with concrete and masonry. Ensure the post hole is properly sized and cleared of debris before placing the post and adding the dry mix. Follow local building codes for post depth, diameter, and concrete fill requirements, particularly for structural deck or fence installations. Do not add excess water, as this reduces compressive strength and extends cure time beyond the rated 30-minute set.
