Review AUTOSEL Concrete Crack Filler Pro Cement Asphalt Waterproof

The **Autosel BackB02 Concrete Crack Filler Pro Cement Asphalt Waterproof** is a high-performance, two-component, epoxy-modified polyurethane crack filler designed to provide durable, long-lasting repairs for structural and non-structural cracks in concrete, asphalt, and other rigid surfaces. Engineered for professionals and DIY enthusiasts alike, this premium-grade product delivers exceptional adhesion, flexibility, and waterproofing properties, making it ideal for both indoor and outdoor applications where moisture resistance and mechanical strength are critical. Its unique formulation combines the best attributes of cementitious and polymer-based fillers, offering superior bonding to concrete, asphalt, and various substrates while maintaining flexibility to accommodate minor movement and thermal expansion without cracking or degrading. The BackB02 is particularly well-suited for repairing cracks in driveways, parking lots, sidewalks, bridge decks, basement walls, and industrial floors, where exposure to water, chemicals, or heavy traffic demands a robust solution. With a fast curing time and a smooth, seamless finish, this product eliminates the need for extensive surface preparation in many cases, though proper cleaning and crack profiling still enhance performance. Its waterproof properties create an effective barrier against moisture infiltration, preventing further deterioration and structural damage, while its high compressive strength ensures durability under heavy loads. Whether used for emergency repairs or planned maintenance, the Autosel BackB02 delivers professional-grade results with minimal effort, making it a trusted choice for contractors and property owners seeking a reliable, long-term solution for crack repair.

**Pros and Cons of buying a Autoseal BackB02 Concrete Crack Filler (Pro Cement Asphalt Waterproof)**

1. **Effective Waterproofing:** This product is designed to provide a strong waterproof seal for cracks in concrete, asphalt, and other surfaces. It prevents water infiltration, which can cause further damage like erosion, structural weakening, or mold growth.

2. **Versatile Application:** Suitable for a variety of surfaces, including concrete, asphalt, and cement-based materials. It can be used for cracks in driveways, patios, parking lots, and other outdoor areas.

3. **Durability:** The product is formulated to withstand harsh weather conditions, including UV exposure, temperature fluctuations, and freeze-thaw cycles. This ensures long-lasting performance and reduces the need for frequent reapplication.

4. **Easy Application:** The product is typically designed for easy application, often requiring minimal tools like a caulk gun or putty knife. It can be applied to clean, dry cracks without extensive surface preparation, making it user-friendly for DIY projects.

5. **Flexible and Elastic:** The filler is often flexible, allowing it to accommodate minor movement or shifting in the cracks without cracking or failing itself. This flexibility helps maintain the seal over time.

6. **Adhesion:** It bonds well to the surfaces it is applied to, providing a strong, long-lasting seal that resists peeling or flaking.

7. **Cost-Effective:** Compared to professional crack repair services, this product offers a cost-effective solution for homeowners or small-scale projects. It can save money on labor costs while still delivering professional-quality results.

1. **Limited Depth Coverage:** The product may not be suitable for very wide or deep cracks. It is typically designed for hairline to quarter-inch cracks. Wider cracks may require additional preparation, such as cleaning and widening, or a different product designed for larger gaps.

2. **Surface Preparation Required:** While the application is often straightforward, cracks must be thoroughly cleaned of debris, loose material, and moisture before applying the filler. Failure to do so can compromise the effectiveness of the seal.

3. **Limited Color Options:** The product may come in a limited range of colors, often matching natural concrete or asphalt tones. If aesthetic matching is critical, this could be a drawback, though the product is typically designed to blend in rather than stand out.

4. **Environmental Conditions:** Application must be done under ideal conditions typically dry and with temperatures within a specified range (often between 40 F and 100 F). Applying it in extreme heat, cold, or wet conditions can affect adhesion and performance.

5. **Not a Structural Repair:** While the product seals cracks effectively, it does not reinforce or structurally repair cracks caused by significant movement or stress in the material. For structural issues, additional measures like underlayment or professional repair may be necessary.

6. **Potential for Overapplication:** Applying too much product can cause it to bulge or sag, leading to an uneven surface that may need to be sanded or trimmed. This can add extra steps to the repair process.

7. **Chemical Sensitivity:** Some users may be sensitive to the fumes or chemicals in the product, particularly during application. Proper ventilation is recommended, and gloves should be worn to avoid skin irritation.

The Autoseal BackB02 Concrete Crack Filler is a reliable and user-friendly option for sealing small to moderate cracks in concrete, asphalt, and cement surfaces. Its waterproofing properties, durability, and ease of application make it a practical choice for DIY projects or routine maintenance. However, it is not a one-size-fits-all solution it is best suited for cracks within its specified range and requires proper surface preparation for optimal results. For wider cracks or structural issues, additional steps or products may be necessary.

If you are dealing with minor cracks in outdoor surfaces and prioritize a cost-effective, long-lasting seal, this product is a strong recommendation. For larger or more complex repairs, consulting a professional or using a specialized repair kit may be advisable.

Purchase the Autoseal BackB02 Concrete Crack Filler if you need a durable, waterproof solution for hairline to quarter-inch cracks in concrete or asphalt. Ensure the surface is clean, dry, and within the recommended application temperature range. Follow the manufacturer s instructions carefully for the best results. For cracks wider than a quarter-inch or those caused by structural issues, consider using a different product or seeking professional advice.
