Surface Preparation:Ensure the concrete is in good condition and free of oil, grease, dust, and other contaminants. High-pressure water blasting is recommended to achieve an open, rough surface profile (CSP 2-3). The surface should be misted to a saturated-surface-dry (SSD) state without standing water before application.
Mixing:Use hand or low-speed drill mixing, adding water to the container before slowly introducing the OverCrete powder. Water ratios range from 5.25 to 5.75 pints per 40 LB bag, depending on the desired consistency. Mixing should not exceed 3 minutes to avoid overwatering or retempering.
Placement:Apply OverCrete using a trowel, broom, or squeegee, ensuring the material fills all voids and cracks. For deeper applications, apply in layers with sufficient drying time between each.
Curing:OverCrete achieves final cure within twenty-four hours. It is crucial to protect the area from rain or excessive water during this period.
Deep Applications:For repairs exceeding 1.5 inches with OverCrete Coarse, it can be extended with up to 50% clean, SSD 3/8 inch aggregate by weight for enhanced volume and stability.
