Affordable Performance with Our Signature Concrete System
Black Hills Concrete Specialties is your local decorative concrete expert, based in the heart of the Black Hills. Founded and operated by Mark Keller, a concrete professional with experience dating back to 1993, our family-owned business brings seasoned skill and a commitment to quality to every project. From vibrant interior floors to sealed and coated commercial surfaces, we focus on finishes that combine performance, durability, and visual appeal.
We proudly offer a better option for customers searching for epoxy contractors. While most epoxy providers offer the same system with custom-ordered flakes and long lead times, our proprietary grind, stain, and seal process delivers a faster, more affordable solution, without sacrificing strength or style. As the Low Cost Alternative to Expensive Epoxy Flooring, we stock all color options locally, eliminating delays and giving you the flexibility to choose the look you want without the wait.
Whether you’re upgrading a garage in Rapid City or revitalizing a business entryway in Spearfish, we specialize in decorative concrete solutions that stand up to the elements and daily use, all backed by decades of experience and a deep commitment to customer satisfaction.

FAQs About BHCS and Our Concrete Services
Here are answers to the most common questions we get about our work and service areas.
What is your concrete finishing process?
We start by grinding the surface of your concrete to remove any old coatings, stains, or surface damage. This step ensures a clean, smooth base for the next layers. Then we apply a decorative stain, which adds rich color and visual depth. Finally, we seal the surface with a durable, low-VOC topcoat that protects against traffic, moisture, and daily wear. The result is a clean, modern finish that’s easy to maintain and built to last in both residential and commercial spaces.
How is your grind/stain/seal process different from epoxy flooring?
Our process offers a similar clean, finished look without the high cost or long wait times that come with traditional epoxy systems. We don’t rely on custom-ordered flakes as our stain colors are in stock and ready to go. The entire system is low in VOCs, nearly odor free, and safe for families and pets. Plus, it’s applied over a diamond-ground surface for a strong, long-lasting finish designed to handle real-world use.
What types of concrete surfaces can you stain?
Interior floors, patios, garages, basements, and commercial slabs are all great candidates.
Is your staining system safe for pets and kids?
Yes, we use ultra-low VOC, non-toxic products that are safe once cured.
How long does a typical concrete coating take?
Most projects are completed within 1–2 days depending on the space size and prep work needed.
Do you offer sealing for existing concrete driveways?
Absolutely. We apply high-performance sealers designed to resist road salts and UV damage.
What’s better: epoxy or polyurethane coatings?
Polyurethane systems last longer, are more flexible, and cost less to maintain over time.
Can you repair cracks or damaged concrete before staining?
Yes, we offer crack repair and resurfacing as part of our prep work.
What if my concrete is old and worn out?
Our resurfacing systems can give old concrete a fresh, textured look that performs like new.
Are there environmental benefits to your concrete finishing process?
Yes. Our process is designed to be both effective and environmentally responsible. We use ultra low VOC stains and sealers, which means there are no harsh fumes and no lingering chemical smell. This makes the process safer for your family, pets, and the environment. Unlike traditional epoxy systems that often involve heavy chemical use and custom-ordered materials, our in-stock products help reduce waste and cut down on unnecessary shipping. By restoring and enhancing your existing concrete instead of replacing it, we also help keep material out of landfills and make better use of what you already have.
Do you travel outside the Black Hills?
Yes, we serve Northeast Wyoming and surrounding areas by request.
