What We Do
Polished Concrete Services
Vancouver WA & Portland OR
2 Palms is a pure polishing specialty. No epoxy coatings, no decorative overlays, no concrete pouring. Just polished concrete, slab correction, surface prep, and restoration — performed with the precision that comes from four decades of hands-on flooring industry experience.
Polished Concrete
Mechanical polishing using progressive diamond tooling to achieve a glass, satin, or matte finish. The process reveals the natural aggregate of the slab and produces a surface that is dense, durable, and easy to maintain. No coatings or overlays — just the concrete itself, refined.
Grind & Seal
The slab is ground to expose aggregate and profile the surface, then sealed with a penetrating or topical sealer. A practical solution for garages, shops, and commercial spaces where a sealed, low-maintenance floor is the priority.
Concrete Restoration
Existing polished or sealed floors brought back to their original condition. We address cracks, staining, surface damage, and loss of sheen — restoring the floor without the cost of replacement.
Polished Concrete Maintenance
Scheduled maintenance to protect and extend the life of your polished floor. We re-densify, re-polish, and re-seal on a cycle that keeps the surface performing at the level it was built to.
Concrete Grinding & Surface Prep
Slab preparation for new coatings, polishing, or flooring installation. We remove existing coatings, adhesives, and surface contaminants, then grind and profile the slab to the correct specification for whatever comes next.
Slab Correction & Flatness
High and low spots, lippage between slabs, and out-of-flat conditions corrected before finishing begins. Proper slab correction is the foundation of a quality polished floor and something most contractors skip.

About Timm Sowders
The Vault & Grit
Position
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. That singular focus is what makes the difference on high-stakes projects.
The Process
How We Polish Concrete
Every project follows our proven four-step process, refined over four decades of work in the Vancouver, WA and Portland, OR metro areas.
Free On-Site Consultation
Timm visits your location to assess the concrete condition, discuss your goals, and provide an honest recommendation for the best finish and process.
Surface Preparation
We address any cracks, repairs, or surface imperfections before grinding begins. Proper preparation is the foundation of a flawless result.
Progressive Diamond Grinding
Using professional diamond tooling, we grind through progressive grits — from coarse to ultra-fine — to achieve the desired level of aggregate exposure and smoothness.
Densification & Final Polish
We apply a concrete densifier to harden the surface, then polish to your chosen finish level — matte, satin, or glass — and apply a final protective treatment.

"The floor is the foundation of everything."
CLIENT TESTIMONIALS
"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 took a botched concrete job, restored it, and brought 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."
