If you’re considering giving your concrete surfaces a new look, you may be asking: what is the process for staining concrete? While the question sounds simple, the answer depends on who you ask. Concrete staining isn’t a one-size-fits-all service, it can vary significantly between contractors, product lines, and regional conditions.
At Black Hills Concrete Specialties, we’ve refined a proprietary method built around a grind–stain–seal system. It’s a process specifically designed to handle the challenges of South Dakota’s climate while delivering stunning, long-lasting results.
Our system balances decorative freedom, durability, and sustainability in ways that many traditional methods don’t. Whether you’re updating a garage floor or reviving an outdoor patio, this process offers a seamless blend of beauty and performance.
As one of the most trusted concrete staining companies in Spearfish, we believe in transparency, so in this article, we’ll break down not just how the process works, but why each step matters, and how it all works together for a finish that holds up over time.

Why Concrete Staining Methods Vary
When asking what is the process for staining concrete, it’s essential to recognize that each contractor might give you a different answer. That’s not necessarily a bad thing. Some jobs require more customization than others.
Methods vary based on:
- Condition of the concrete (new, old, cracked, previously coated)
- Location (indoor vs. outdoor)
- End goal (decorative, industrial, UV resistance, slip resistance)
- Preferred products (acid stain, water-based stain, hybrid coatings)
- Contractor skillset (not all companies offer full grinding or decorative overlays)
At Black Hills Concrete Specialties, we focus on finish work, not raw concrete pours, which allows us to specialize in systems that truly bring the surface to life. Our proprietary grind–stain–seal method is engineered to be both cost-effective and long-lasting.
Tools and Materials Used in Concrete Staining
Before jumping into the method itself, it helps to know the tools of the trade.
- Grinders: Used to mechanically open the concrete’s pores and level the surface.
- Stains: Water-based, acid-based, or hybrid formulas that penetrate the concrete to deliver color.
- Sealers: Acrylic, urethane, or epoxy-based topcoats that protect the stained surface.
- Surface Prep Equipment: Vacuums, scrapers, or degreasers to remove residue, dust, and contaminants.
- Optional Add-Ons: Quartz or flake broadcasts, anti-slip additives, and texture overlays.
The choice of materials and machinery can significantly impact the final look, longevity, and safety of the floor.
Our Method: A Closer Look at Grind–Stain–Seal
At BHCS, we use a proven three-phase system: Grind → Stain → Seal.
These steps are arranged in a specific order for good reason. When done right, each phase prepares the surface for the next, resulting in a bonded finish that won’t flake, fade, or wear prematurely.
The goal is more than just color. We create a durable, decorative concrete surface that performs as beautifully as it looks. Let’s dive into each step.
Step 1: Grinding the Surface – Preparing the Canvas
Think of the concrete slab as a blank canvas. Before any stain can be applied, the surface must be open and clean.
Why We Grind:
- Removes surface imperfections like glue, paint, or coatings
- Opens up concrete pores to accept stain more evenly
- Ensures stain penetration for color that doesn’t peel
- Levels the surface for consistent sealing later
This step is skipped by some contractors, but that usually results in blotchy or short-lived results. Grinding sets the foundation for everything that follows. At BHCS, we use industrial-grade grinders with dust control to ensure both surface quality and job site cleanliness.
Step 2: Staining – Adding Color with Control
After the surface is opened and cleaned, we move to the staining phase. This is where creativity and chemistry meet.
Our Approach to Staining:
We primarily use water-based, ultra-low VOC stains, which are both safe and versatile. These formulas produce finishes that range from solid to translucent, with color blends that mimic marble, leather, or natural stone.
Why This Step Matters:
- Introduces color as a permanent part of the concrete
- Allows for artistic effects without toxic fumes
- Offers unmatched design freedom compared to flooring
- Doesn’t trap allergens or bacteria like carpet or grout
We apply stains using sprayers, brushes, or sponges depending on the effect you’re going for. The surface is then allowed to dry and chemically bond before sealing.
Step 3: Sealing – Locking In the Beauty
This is the make-or-break stage. Without sealing, stain would fade quickly and absorb moisture, oils, or UV damage.
Our Sealing Process:
We apply high-performance sealers designed to match the use case—whether it’s a garage, patio, commercial space, or basement. Some applications include slip-resistant finishes, especially in wet or high-traffic areas.
Why Sealing Is Critical:
- Protects against stains, abrasion, and fading
- Enhances color vibrancy and sheen
- Makes surfaces easy to clean
- Can be re-applied over time to refresh the look
Some contractors seal too soon or use the wrong type of sealer for the environment. At BHCS, we ensure cure times are respected, and product compatibility is never compromised.
How Our Process Compares to Other Methods
Here’s how our grind–stain–seal system stacks up against common alternatives:
| Method | Preparation | Durability | Aesthetic Control | VOC Level | Maintenance |
| BHCS Grind–Stain–Seal | Full surface grind | High (forklift-rated) | Full custom control | Ultra-low | Easy |
| Quick Acid Stain | Minimal cleaning | Moderate | Limited color options | High | Prone to fading |
| Paint or Coatings | No prep | Low to moderate | Wide color options | Varies | Frequent recoat needed |
| Flooring (tile/vinyl) | Underlayment needed | Varies by product | Consistent | Varies | High grout or surface care |
Our method at BHCS isn’t just about appearance; it’s about performance, health, and customization without compromise.
Secondary Benefits: Air Quality, Durability, and Maintenance
Aside from aesthetic appeal, there are hidden benefits to a properly stained and sealed concrete floor:
- Air Quality: Our low-VOC stains and sealers emit no harsh fumes, making them safe for kids, pets, and indoor use.
- Allergen Control: No fibers, grout, or gaps to trap dust, allergens, or moisture.
- UV Resistance: Perfect for sun-exposed spaces, as our colors won’t fade or yellow.
- Load Tolerance: Finishes are forklift-rated and engineered for both foot and vehicle traffic.
- Cleaning Simplicity: A damp mop is usually all it takes to keep things looking great.
What Impacts the Final Look and Lifespan?
The grind–stain–seal system is built for durability, but several key factors still influence how the final surface looks and how long it lasts. The age and condition of the concrete are important. Newer slabs tend to absorb stain differently than older ones, and surfaces with cracks may require repair or overlays before staining begins to ensure a consistent finish.
How the stain is applied also makes a difference. Techniques like spraying, brushing, or layering each produce different levels of color depth and texture. Environmental conditions during the job, such as temperature, humidity, and exposure to sunlight, can affect how the stain cures and bonds to the concrete.
Ongoing maintenance helps preserve the look and performance of the surface. Reapplying the sealer every few years helps keep the finish looking fresh and protects it from wear. For high-use spaces such as garages or pool decks, we may recommend using slip-resistant additives or applying a thicker seal coat to enhance durability and safety.
The Difference Is in the Details
By now, it’s clear that the answer to what is the process for staining concrete isn’t universal. While the basic principles of surface preparation, staining, and sealing apply across the board, how each step is executed can make all the difference in the end result.
Some professionals may take shortcuts, while others may layer on extra steps for specialty effects. What matters most is that the process is appropriate for the surface conditions, use-case, and desired look.
Whether it’s grinding to ensure proper stain penetration or choosing a sealer that fits the environment, each phase of the process plays a critical role in the floor’s performance and appearance over time.
Concrete staining is part science, part craftsmanship. It’s not just about color, it’s about creating a surface that performs under pressure, weathers time gracefully, and reflects the character of the space it’s in.
If you’re planning a project of your own, take time to ask how each step will be handled, what products will be used, and why. A well-informed process leads to better decisions, and much better floors.
