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 publish practical guidance on water-based release agents, formwork preparation, application control, concrete placement, and surface inspection. Product performance depends on the product instructions and project conditions, so teams should validate changes on a representative mockup.
