How Epoxy Flooring Is Applied
Epoxy floor coatings are a popular choice in garages, warehouses, commercial spaces, and even residential interiors thanks to their durability, sleek look, and resistance to wear and chemicals. While DIY epoxy kits are available, professional application ensures a flawless finish and long-lasting performance. But what exactly goes into a professional epoxy floor installation?
In this post, we’ll walk you through the step-by-step process professionals use to apply epoxy floor coatings, and why each stage matters.
Step 1: Evaluation and Planning
Before any tools hit the floor, professionals assess the surface. Is the concrete in good shape? Are there cracks, moisture issues, or old coatings? These evaluations help determine:
The right epoxy formulation
Necessary surface prep
Moisture mitigation needs
Moisture testing is often done using a calcium chloride test or a relative humidity probe, as trapped moisture can cause epoxy to peel.
Step 2: Surface Preparation
The most critical step of any epoxy application is surface prep. A poorly prepared surface is the #1 reason epoxy coatings fail.
Techniques used:
Diamond grinding or shot blasting to open the concrete’s pores
Crack and joint repair with epoxy patching materials
Degreasing and cleaning to remove oil or contaminants
This creates the ideal surface profile (similar to 80-grit sandpaper) for the epoxy to bond effectively.
Step 3: Primer Coat
A primer coat is typically applied first, which improves adhesion and helps seal the concrete. Depending on the condition of the floor, professionals might use:
Moisture-tolerant primers
Self-leveling primers for uneven floors
The primer also fills in tiny imperfections, preparing a smooth base for the epoxy.
Step 4: Base Coat Application
Once the primer is cured (usually 12–24 hours), the base coat of epoxy is applied. Professionals typically:
Mix the two-part epoxy resin on-site
Pour it out in ribbons to avoid overworking
Spread it using a squeegee or roller in a uniform manner
This layer forms the bulk of the coating system and provides the color and body of the floor.
Step 5: Decorative Flakes or Additives (Optional)
For added texture and aesthetics, professionals may broadcast vinyl chips, quartz, or metallic pigments into the base coat. These not only enhance the visual appeal but also improve slip resistance.
Flakes are typically broadcast to rejection, meaning they fully cover the wet epoxy, and are later scraped and vacuumed for a smooth finish.
Step 6: Topcoat Application
After the base coat (and optional flakes) cure, a clear topcoat is applied. This adds:
UV protection
Abrasion and chemical resistance
Gloss or matte finish options
Professionals often use polyaspartic or polyurethane topcoats, which cure quickly and hold up well in demanding environments.
Step 7: Curing and Final Inspection
The final step is letting the floor cure properly, which can take from 24 hours (light foot traffic) to 5–7 days (vehicle traffic), depending on the product used.
Professionals will:
Check for coverage uniformity
Ensure no bubbles, fisheyes, or roller marks
Confirm adhesion and finish quality
Why Hire a Professional?
While epoxy floor kits at big box stores may seem tempting, professionals bring:
Specialized equipment for prep and application
Expertise in choosing the right products
Higher-quality materials not sold at retail
Warranties and peace of mind
Done right, a professionally installed epoxy floor can last 10–20 years and withstand heavy abuse.
Final Thoughts
Epoxy floor coating isn’t just paint—it’s a multi-step process that demands skill, timing, and precision. By hiring professionals, you ensure a beautiful, durable floor that not only looks great but performs under pressure.
