Our Concrete Reinforcer was developed by Leech Adhesives to improve flexural strength and water resistance when casting high-quality concrete applications. When you don’t want your concrete driveway, walkway, steps, patio to crack, use Leech Concrete Reinforcer. Quality is the reason to “Stick with Leech”
Leech Concrete Reinforcer
Premium Waterproofing, Bonding, Sealing Additive
An additive designed to bond and seal
Product:
1 gallon plastic container: LCR-105
Applications:
- Seals concrete, plaster, stucco & masonry
- All interior and exterior concrete applications
Product Characteristics:
- To prevent future cracks, delamination and water penetration, it is recommended to add Leech Concrete Reinforcer directly into the wet concrete mixer prior to casting at the rate of 2 gallons/94 pounds. Product will exhibit superior properties in flexural strength, water resistance and improved adhesion if bonding other items to concrete.
- If Concrete is already cast, you can use a spray gun, brush, or roller to apply Concrete Reinforcer to the concrete surface. This will improve all surface characteristics
- Not for use in water submerged applications
- Recommended to use above 45⁰F
Leech Adhesives Concrete Reinforcer FAQs
1. What Are the Benefits of Using Leech Concrete Reinforcer in My Mix?
Leech Concrete Reinforcer is a high-performance additive specifically engineered to improve the flexural strength and water resistance of concrete, plaster, stucco, and masonry. By adding it directly to your wet mix, you significantly reduce the risk of future cracks, delamination, and water penetration. It is an essential solution for ensuring the longevity of high-quality concrete applications like driveways, patios, and walkways.
2. Can I Apply Concrete Reinforcer to Concrete That Has Already Been Cast?
Yes. While it is typically recommended to add Leech Concrete Reinforcer to the wet mixer for maximum internal strength, it can also be used as a surface treatment. If your concrete is already cast, you can apply the product using a spray gun, brush, or roller to improve surface bonding, sealing, and overall durability.
3. Is Concrete Reinforcer Waterproof and Suitable for Most Construction Environments?
Our Concrete Reinforcer provides water resistance and is ideal for both interior and exterior applications. However, it is important to note that this type of reinforcer is not recommended for water-submerged applications (such as the interior of a swimming pool or underwater structures).
4. Does Using a Concrete Reinforcer Affect the Drying or Curing Time?
Concrete Reinforcer from Leech Adhesives is designed to improve the quality of the cure rather than drastically change the timeline. While it may slightly speed up the initial set (making the concrete workable a bit sooner), the overall curing process still requires 28 days to reach maximum structural integrity. Because the reinforcer helps retain moisture internally, it actually promotes a more uniform cure, which is critical for preventing hot weather surface cracks.
5. What is the Shelf Life of Leech Concrete Reinforcer, and How Should it Be Stored?
When stored in its original, unopened container in a cool, dry environment (ideally between 45°F and 85°F), our Concrete Reinforcer typically has a shelf life of 12 to 24 months. It is important to protect the product from freezing; if the liquid is allowed to freeze, the polymer chains can break down, making the product no longer effective. Always ensure the cap is tightly sealed after use to prevent the liquid from skinning over or drying out in the jug.
