QUIKRETE® Zip and Mix – FastSet Repair Mortar will dry a grey color that may not match the surrounding concrete. When QUIKRETE® Zip and Mix – FastSet Repair Mortar is placed at temperatures below 50 ºF (but above 32 ºF), cold weather precautions should have been taken to promote proper curing. These include, but are not limited to, the following: store the raw materials in a warm temperature before use, use warm (not hot) water to mix, and ensure that the mortar is protected from freezing for at least 48 hours using plastic sheeting, insulated blankets, or other means. Rain will not negatively impact the repair as long as the material was fully set when the rain began. Keeping the material protected from freezing is more imperative to ensure the repair does not get damaged.
