How to Use QUIKRETE Zip & Mix Repair Mortar
First, you must mix QUIKRETE with the correct amount of water. To mix, unzip the enclosure and break through the protective seal on the pouch. Then add 10 ounces (1-1⁄4 cups) of water to the mortar, remove excess air from the package and rezip it, then knead thoroughly. Kneading makes sure the dry mixture and water fully mix for proper curing and strength.
Once the mortar is mixed, unzip the pouch and apply the material with the included application tool. QUIKRETE Zip & Mix Repair Mortar doesn’t require bonding adhesive, and you can apply it to structurally sound, dampened concrete.
The mortar’s unique properties allow you to sculpt it during application. With 20 minutes of working time, the repair mortar is ideal for both small and large, vertical or horizontal repairs. You can use it for cracks, damaged curbs, deteriorating sewer infrastructure, cracked retaining walls, chipped decorative moldings, damaged bridge columns, and more. The mortar can fill cracks and defects ranging from feather-edge up to two inches deep.
Additional QUIKRETE Considerations
QUIKRETE Zip & Mix Repair Mortar will achieve 4,500 psi (pounds per square inch) in compression strength once fully cured. This high strength makes it suitable for structural repairs on critical infrastructure. Proper surface preparation is key — you must chip away all loose debris and deteriorated concrete so the mortar bonds tightly to the solid underlying material.
For best results, dampen the repair area before application and don’t exceed two-inch layer thickness when building up or filling in defects. You can apply the mortar in multiple layers if you dampen each cured layer before applying the next one.

Is QUIKRETE Zip & Mix Repair Mortar the Right Choice?
Before choosing this product for your project, ask yourself a few questions. Does your damaged concrete or masonry need high-strength repairs completed rapidly? Will you be doing small-scale repairs that suit the specialized packaging? Have you reviewed the preparation and application tips to use the product successfully?
QUIKRETE Zip & Mix Repair Mortar is best for repairing and restoring damaged concrete and masonry surfaces. Its high strength and fast cure time make it well-suited for infrastructure repairs you need to complete quickly.
The unique packaging works well for small repairs but may not be the most cost-effective choice for large projects. For those, a traditional bagged mortar mix may be better.
