About Concrete Surface Lab

Beyond the Surface

Concrete Surface Lab is the content site for Yunzhu New Materials. We publish practical guides for contractors and engineers who want cleaner concrete finishes, fewer defects, and better release-agent decisions.

For decades, bugholes, discoloration, and sticking have been treated as unavoidable side effects of concrete casting. We think that is a process problem, not a fact of life.

Our Philosophy

• No more hours spent grinding.
• No more expensive cosmetic repairs.
• No more hazardous waste oil.

Our factory site at Visit the factory site handles product supply. This site focuses on the application science behind water-based release agents, formwork conditions, and concrete surface quality.

What We Do

We specialize in Water-based Release Agent Technology. Unlike traditional oil-based barriers, our solutions rely on wax emulsions and polymer chemistry to create a breathable film that lets trapped air escape while still delivering clean 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.
