Internationally known for his whimsical chalk art, David Zinn transforms ordinary sidewalks and manhole covers into imaginative worlds. While his chalk installations are temporary, Epoxytec’s structural-grade epoxies and protective coatings are engineered to last—mitigating infiltration, resisting chemical attack, and extending the service life of municipal infrastructure.

This September at WEFTEC 2025, David is teaming up with Epoxytec | Tnemec to highlight the hidden infrastructure beneath our feet in a whole new way.

While most people walk past manhole covers without noticing, David sees these overlooked spaces as canvases for creativity. For David, these overlooked spaces are canvases for creativity. For Epoxytec, they are critical access points to underground systems that safeguard our communities.

Bringing David to WEFTEC is more than art—it’s a reminder of how the visible and invisible work together:

On the surface: David sparks imagination through his chalk art.
Beneath the surface: Epoxytec protects and restores essential infrastructure.
