A water-based concrete treatment agent that delays the surface setting of fresh concrete, facilitating the formation of exposed aggregate finishes and superior bonding surfaces.
Water-based Eco-friendly Formula
Non-toxic and safe with zero VOC content.
Uniform Exposed Finish
Uniform aggregate exposure without acid washing or heavy chipping, cutting labor costs.
Controllable Etching Depth
Etching depth adjustable up to 10 mm by varying coating thickness.
No Impact on Structural Strength
It will not weaken the bonding force of concrete or steel, maintaining the intact structural strength of the substrate.

This concrete surface retarder from LU CAI enables easier and more uniform construction of exposed aggregate finishes. It is applied directly onto freshly poured concrete surfaces to inhibit the hardening of cement paste, delivering highly controllable exposed aggregate decorative effects. Unlike sugar-based retarders with inconsistent retarding performance, LU CAI selectively slows the hydration process to a controllable depth.
LU CAI concrete retarder comes with twelve preset exposure depths distinguished by color coding, enabling consistent and repeatable removal of cement paste and exposure of aggregates. By extending the window for washing off surface cement slurry, LU CAI concrete retarder allows the underlying concrete to fully cure, locking aggregates in place and reducing spalling. Water-soluble in nature, LU CAI concrete retarder can be easily cleaned away with high-pressure water guns and scrubbing equipment.
LU CAI concrete retarder forms a polymer film that acts as a water-retention barrier and temporary curing agent. It shields freshly placed concrete from light rain damage and minimizes moisture loss.
