When you’re joining new concrete to existing slabs in Kansas City, proper bonding determines whether the new view details layer adheres or separates. Kansas City’s wide temperature swings and freeze–thaw cycles make choosing the right bonding agent critical for long-term open link performance.
Top Bonding Options
- Acrylic bonding agents: The most common for overlays and patching. They’re water-based, easy to apply, and create a flexible film between old and new concrete. Epoxy bonding adhesives: Two-part systems that provide the strongest bond—ideal for structural repairs, vertical surfaces, and heavy-duty slabs. Polymer-modified cementitious slurries: Combine cement and polymers to improve chemical adhesion and match the coefficient of expansion between layers.
How to Apply for Best Results
- Surface prep: Clean, degrease, and mechanically roughen the existing slab to open pores and remove sealers. Apply evenly: Roll or brush on bonding agent per manufacturer’s instructions. Avoid puddling. Timing: Some agents must dry tacky; others require wet-on-wet placement. Follow label directions precisely.
KC Climate Tips
- Use products rated for freeze–thaw durability. Avoid bonding in direct sun or high winds; Kansas City heat can flash-dry the agent. Maintain surface temps between 50–80°F for best cure and bond strength.
Common Mistakes
- Skipping surface profiling—smooth old concrete offers little mechanical grip. Using latex paint instead of real bonding agent—it peels under stress. Pouring without timing the bond layer properly—leads to delamination.
Bottom Line
For Kansas City overlays and patching, an acrylic or epoxy bonding agent matched to your mix type and temperature range ensures new concrete bonds solidly to old. Prep, check this out timing, and weather awareness are the key to success.
