Larsen Weld-Crete: Revolutionizing Concrete Bonding Solutions

Concrete construction and repair demand durability and reliability—and that's where Larsen Weld-Crete shines. As a flagship bonding agent from Larsen Products, Weld-Crete has earned a solid reputation among contractors, architects, and DIY enthusiasts alike for its superior performance in bonding new concrete, stucco, tile setting beds, and terrazzo to a variety of structurally sound surfaces.

A Legacy of Innovation

For decades, Larsen Products has been at the forefront of developing innovative solutions for the construction industry. Weld-Crete is a testament to that legacy. Formulated with a patented blend of polyvinyl acetate homopolymer, this ready-to-use, water-based emulsion was engineered to meet the rigorous demands of both interior and exterior applications. Its unique formulation not only ensures a robust bond but also provides the flexibility needed to accommodate the natural movements and stressors in concrete structures.

Key Features & Benefits

Versatility at Its Best

• Multiple Applications: Weld-Crete bonds new concrete, Portland cement plaster, and cementitious mixes to various substrates including concrete floors, walls, columns, beams, steps, ramps, and even surfaces like brick, tile, and metal.
  
  
• Interior & Exterior Use: Whether you’re tackling an indoor renovation or an outdoor repair project, Weld-Crete’s robust performance remains consistent.
• Extended Open Time: One of its standout features is the flexible application window—it can be applied anywhere from 1 hour to 10 days before the placement of the new concrete, providing unmatched scheduling convenience on the jobsite.

Superior Bonding Performance

• Strong and Durable: Weld-Crete creates a continuous, blue-hued film over the substrate, ensuring a secure and crack-resistant bond even under adverse conditions.
• Ease of Application: Its water-based formula allows for simple application methods—using a brush, roller, or sprayer—making it accessible for both large-scale contractors and home DIYers.
  
  
• Proven Reliability: Field tests and user testimonials echo the product’s efficacy, with many professionals noting its consistent performance over 30 years of use.

Practical Applications

Larsen Weld-Crete is not just for new construction—it’s equally effective in repair and restoration projects. Here are some of its key applications:

• Concrete Repairs: Ideal for bonding thin layers of new concrete to existing surfaces, ensuring a seamless and durable repair.
• Stucco and Plaster Applications: It serves as a reliable bonding agent for setting beds in ceramic tile installations and for applying plaster or stucco overlays.
• Versatile Substrate Compatibility: Beyond concrete, Weld-Crete effectively bonds to surfaces like brick, block, tile, and even certain types of painted surfaces, provided they are structurally sound and properly prepared.

Tips for Optimal Application

To maximize the benefits of Weld-Crete, proper surface preparation is crucial:

1. Clean and Prepare: Ensure the substrate is free of dust, oil, loose material, or contaminants. For painted or previously finished surfaces, a light abrasion may be necessary.
2. Uniform Application: Use a brush, roller, or sprayer to apply a consistent blue film across the surface.
3. Allow Adequate Drying: A drying time of at least one hour is recommended before applying the new concrete overlay—unless your project specifications call for immediate bonding with fast set patching materials.
