Can this be used to level a deep recession/puddle. My concrete slab was not corrected poured leaving a recession that collects water. Can I use this?

Thank you for posting your inquiry. DAP Ready-Mixed Concrete Patch is designed, marketed and labeled for use in minor masonry repair (not as a replacement/substitute for dry cement repair products). As indicated on the product package label and supporting product literature: "Used to patch small cracks and breaks, or spot level concrete and masonry surfaces such as basement walls, patios, steps, sidewalks and driveways." and "If area to be patched is deeper than 1/2 inch, apply patch in 1/4-inch layers, maximum depth 1 inch, allowing each application to dry." This product is not recommended for use in applications where it may be subject to standing/ponding water. Based on the information that you have provided regarding your intended application, the use of a traditional dry-mixed portland cement patching product would be the most appropriate choice for your needs. Should you require further assistance, please feel free to follow up directly with DAP’s Technical Customer Service Department at 888-327-8477.
