A:  Each 50 lb bag of QUIKRETE® Polymer Modified Structural Repair will yield approximately 0.43 cu ft (12 L) of material. When placed at ½”, this volume will cover approximately 10.3 square feet. Yields will vary with waste, uneven subgrade, etc.

A:  QUIKRETE® Polymer Modified Structural Concrete Repair should not be used as a coating. Use for patches less than 2 ft2 (0.19 m2).

A:  QUIKRETE® Polymer Modified Structural Repair is a polymer modified and shrinkage-compensated rapid setting, high strength repair material designed for vertical and horizontal structural concrete repairs, above and below grade.

A:  QUIKRETE Polymer Modified Structural Repair is suitable for vertical repairs, however it is not designed for overhead work. Instead, we recommend QUIKRETE FastSet Repair Mortar #1241, which was designed for overhead work in particular.

A:  Polymer Modified Structural Repair can be tapered to a feather edge of approximately 1/16".

A:  After the QUIKRETE® Polymer Modified Structural Repair has cured for a minimum of 28 days, you may consider applying either QUIKRETE® Concrete & Masonry Waterproofing Sealer (No. 8800-05), which is a water-based, highly water resistant, silane-siloxane formulation designed to waterproof and seal without changing the surface appearance, or QUIKRETE® Concrete & Masonry High Gloss Sealer (No. 8800-06), which is a water-based, high gloss, acrylic clear sealer designed to waterproof, seal, and enhance the color. Before applying sealer, make sure water will readily absorb in all areas of the application and the surface is clean and free of dirt, dust, oil, and other bond breakers. If water beads up, then the surface will need to be cleaned and any previous sealing materials would need to be removed prior to applying the sealer or the sealer will only adhere to some of the sections, which may result in an uneven appearance.

A:  This product is suitable, when mixed and applied per package instructions. For tuckpointing, we recommend Mortar Mix #1102.

A:  QUIKRETE® Polymer Modified Structural Repair is not appropriate for a large surface area (more the 2 square feet). QUIKRETE® Sand/Topping Mix is recommended for placement as a concrete overlay of 1/2 inch to 2 inches. For an application less than 1 inch thick, QUIKRETE® Sand/Topping Mix blended with QUIKRETE® Concrete Acrylic Fortifier replacing a portion of the water content is recommended. If a thicker topping, between 1 – 2 inches thick, is desired, QUIKRETE® Sand/Topping Mix may be applied after a painted on coat of QUIKRETE® Concrete Bonding Adhesive is applied and dry. Do not use QUIKRETE® Concrete Bonding Adhesive and QUIKRETE® Concrete Acryllic Fortifier in the same application.

A:  Yes, QUIKRETE® Polymer Modified is suitable for making repairs on a concrete driveway. This product is not intended to be used as a coating or over a large area (must be less than 2 square feet). Please note that the concrete substrate needs to be sound, clean, unsealed/uncoated, and free of any dust, loose debris, and any other potential bond breakers. When making repairs, getting a good color match can be difficult - we always recommend trialing a small quantity of the repair material in an inconspicuous area, and allowing it to cure for at least 24 hours to determine whether the color and overall appearance are acceptable before using the material in less discrete areas.
