Beyond the Surface

Concrete Surface Lab is not just another chemical supplier. We are a technical initiative dedicated to a single mission: Eliminating the need for manual patching and sacking in modern construction.

For decades, engineers and contractors have accepted bugholes (surface air voids), discoloration, and sticking as “unavoidable” side effects of concrete casting. We disagree.

Our Philosophy

We believe that Fair-Faced Concrete should be accessible, predictable, and cost-effective.

Powered by Yunzhu Technology

This platform is the international technical hub for Yunzhu New Materials, a leading chemical manufacturer based in China. While our factory produces thousands of tons of release agents annually, Concrete Surface Lab focuses on the application science.

We bridge the gap between complex chemical formulas and real-world job site conditions.

What We Do

We specialize in Water-based Release Agent Technology. Unlike traditional oil-based barriers, our solutions rely on advanced wax emulsions and polymer chemistry to create a “breathing” film that allows trapped air to escape while ensuring a mirror-like separation.

Meet the Expert

Marco Zhang Founder & Technical Lead

With over a decade of experience in chemical formwork solutions, Marco has consulted on infrastructure projects across Asia and Africa. He established this lab to share transparent, data-driven insights with the global civil engineering community.

“A release agent costs less than 1% of the concrete budget, but it determines 90% of the visual quality. Don’t let cheap oil ruin your expensive structure.”
