Polished Concrete
Mechanical polishing using progressive diamond tooling to achieve a glass, satin, or matte finish. No coatings or overlays — just the concrete itself, refined.

About Timm Sowders
Master Concrete Polisher
Since 2004
Timm Sowders has been in the flooring industry since 1984 and has specialized exclusively in concrete polishing since 2004. That background — coming from the flooring side rather than the concrete pouring side — shapes everything about how 2 Palms approaches a job.
The focus is on the finished surface: how it performs, how it holds up, and how it looks ten years from now. Slab correction, proper densification, and progressive diamond work done in the right sequence. No shortcuts, no coatings applied over problems that should have been fixed first.
2 Palms does not pour concrete, install epoxy, or apply decorative overlays. The work is polished concrete, slab correction, surface prep, and restoration — and nothing else.
How We Work
The Process
Site Assessment
We visit the site, assess the slab condition, identify any issues that need to be addressed before finishing, and give you a clear scope and price.
Slab Correction
High spots ground down, low areas filled, lippage between slabs corrected. This step is what separates a floor that looks right from one that just looks polished.
Progressive Diamond Work
Starting with the appropriate grit for the slab condition and working up through the sequence. Each pass refines the surface and prepares it for the next.
Densification
Chemical densifier applied to harden the surface and fill the pores of the concrete. This is what makes a polished floor durable rather than just shiny.
Final Polish & Seal
Polished to the specified finish level — matte, satin, or glass — and sealed to protect the surface and lock in the sheen.
Inspection & Handoff
Final walkthrough with the client. We don't leave until the floor meets the specification and you're satisfied with the result.

“The floor is the foundation of everything.”
What Clients Say
Client Reviews
“I first heard Timm's name a decade ago from top builders in Parade of Homes and Street of Dreams. Later, when he was chosen for the first Porsche Design Studio in the U.S., that set the bar. A Texas vendor told me, 'If you can get him, he's the guy.' Timm takes a botched concrete job, restores it, and brings it to life exactly as envisioned. Timm delivers where others say it can't be done.”
“When Timm came out to see the job and give us a bid, Chris told me that he would become my new favorite contractor in our complex because he was so thorough and professional.”
“I had my garage colored and polished three years ago by 2 Palms. I am super hard on my work area and it is holding up better than expected. I love working on cars and this floor has lost a little color from the caustic stuff I am always spilling on it, but it still looks great.”
