What happens in this clip
Before applying any repair products, it is crucial to thoroughly clean the concrete cracks to ensure proper adhesion and a lasting repair. Use a pressure washer to forcefully remove loose concrete, dirt, debris, and any other contaminants from within and around the cracks. This step is vital for eliminating anything that might prevent the repair product from bonding effectively. For areas with very deep or wide cracks, or loose chunks of concrete, it may be necessary to use a chisel or a rotary hammer to carefully remove failing material. After pressure washing, allow the cracks and surrounding concrete to dry completely. Then, use a shop vacuum or an industrial vacuum to suck out any remaining water, dust, or fine particles from deep within the cracks. This ensures the cracks are impeccably clean and dry, providing an ideal surface for the crack repair product.
Goal: Ensure cracks are clean and free of debris for a lasting repair

About the full video
This project provides a step-by-step guide on how to effectively repair concrete cracks using a two-part epoxy system and silica sand. The process emphasizes thorough preparation, precise application, and proper finishing techniques to create a durable, flexible, and aesthetically pleasing repair that prevents further structural issues and water damage.
Step 1 of 5: Clean the Damaged Area
Using a stiff brush or wire brush, scrub the damaged area to dislodge any loose concrete, dirt, or debris. For stubborn dirt or efflorescence, a pressure washer or garden hose with a strong spray can be used. After brushing, use a shop vacuum or compressed air to remove all dust and fine particles from the crack and surrounding area. Ensure the area is completely dry before proceeding.
