Decorative color chips, often referred to as flakes or flecks, are a popular addition to epoxy and resinous flooring systems. These small pieces of polymer resin add texture, color, and durability to surfaces that might otherwise look plain or industrial. Whether you are upgrading a residential garage, a basement, or a commercial showroom, understanding how to select and apply these chips is the key to a professional-grade finish.
In this guide, we will explore everything you need to know about decorative color chips. You will learn about the different types available, the benefits they provide beyond aesthetics, and a step-by-step process for achieving a flawless application. By the end, you will have the confidence to transform any concrete surface into a beautiful, high-performance floor.
What Are Decorative Color Chips?
Decorative color chips are composed of water-based resin materials, inorganic minerals, and various pigments. They are thin, flat, and come in a variety of shapes and sizes. Most commonly, these chips are used in conjunction with epoxy, polyaspartic, or urethane floor coatings.
When these chips are broadcasted onto a wet base coat, they bond with the resin to create a multi-colored, textured surface. Once the base coat cures, a clear topcoat is applied over the chips to lock them in place and provide a smooth, protective finish. This creates a look that mimics the appearance of terrazzo or granite at a fraction of the cost.
Common Sizes and Shapes
Color chips are typically available in several standard sizes. The size you choose will significantly impact the final look of your floor. The most common sizes include:
- 1/4 Inch: The most popular choice for garages and residential spaces. It provides a balanced, traditional “flecked” look.
- 1/8 Inch: A smaller size that creates a more refined, intricate pattern similar to fine stone.
- 1/16 Inch: Very small chips used for highly detailed designs or when a more uniform color is desired.
- Random Shapes: Some chips are intentionally irregular to provide a more natural, organic appearance.
The Benefits of Using Color Chips
While most people choose decorative color chips for their visual appeal, they offer several practical advantages that improve the longevity and safety of your flooring. Understanding these benefits can help you decide if a chip-based system is right for your project.
Enhanced Durability
Adding a layer of chips to your epoxy floor increases the overall thickness of the coating system. This extra layer acts as a buffer against impact, abrasions, and heavy foot traffic. In high-traffic areas like workshops or commercial kitchens, this added durability is essential for preventing the floor from wearing down prematurely.
Slip Resistance
Standard epoxy floors can become very slippery when wet. Decorative chips create a slightly textured surface that provides much-needed traction. By breaking up the smooth surface of the resin, the chips make the floor safer for walking, even in environments where spills or moisture are common.
Hiding Imperfections
Concrete floors are rarely perfect. They often have small cracks, pits, or uneven patches. A solid-colored epoxy floor can actually highlight these flaws. However, a multi-colored chip blend creates a visual camouflage that hides minor imperfections in the substrate, resulting in a more uniform and attractive appearance.
Choosing the Right Color Palette
The color of your floor sets the tone for the entire room. Because decorative chips come in hundreds of individual colors, the possibilities for customization are nearly endless. Most suppliers offer pre-mixed blends, but you can also create a custom mix to match your specific decor.
Neutral vs. Bold Blends
Neutral blends consisting of grays, blacks, whites, and tans are the most common for residential garages. These colors are excellent at hiding dirt and tire marks while providing a clean, modern look. On the other hand, bold blends with blues, reds, or greens are often used in retail spaces or themed rooms to make a statement and reinforce branding.
Full Broadcast vs. Partial Broadcast
You must also decide how many chips you want to use. This is referred to as the “broadcast rate.”
- Full Broadcast: Chips are applied until the base coat is completely covered and no more chips can stick. This results in a floor that is 100% chip-covered, offering maximum durability and texture.
- Partial Broadcast: Chips are scattered lightly across the floor, allowing the base coat color to show through. This is a more subtle look and requires fewer materials.
How to Apply Decorative Color Chips
Applying color chips requires careful timing and preparation. If you are doing this as a DIY project, it is helpful to have a second person to assist with the broadcasting while you focus on rolling out the base coat.
Step 1: Surface Preparation
The most important part of any flooring project is preparation. The concrete must be clean, dry, and porous. Most professionals recommend diamond grinding or acid etching the surface to ensure the epoxy can bond properly. Remove all dust, oil, and old coatings before beginning.
Step 2: Apply the Base Coat
Mix your epoxy resin according to the manufacturer’s instructions. Use a roller to apply an even layer across a small section of the floor (usually about 100 square feet at a time). Do not try to coat the entire floor at once, as the epoxy may begin to harden before you can apply the chips.
Step 3: Broadcast the Chips
While the base coat is still wet, begin tossing the chips into the air, allowing them to fall evenly onto the surface. Avoid throwing them directly down at the floor, as this can cause clumps. Think of it like sowing seeds or tossing confetti. If you are doing a full broadcast, keep throwing until no wet spots are visible.
Step 4: Scrape and Clean
Once the base coat has fully cured (usually 8 to 24 hours), you will need to remove any loose or protruding chips. Use a floor scraper or a large flat blade to lightly scrape the surface. This levels out the chips and ensures the floor isn’t too sharp. After scraping, vacuum the floor thoroughly to remove all debris.
Step 5: Apply the Topcoat
The final step is to apply a clear topcoat, such as a polyurethane or polyaspartic. This layer seals the chips and provides UV protection and chemical resistance. Use a squeegee or a high-quality roller to apply the topcoat evenly. This will give your floor a beautiful glossy or satin finish and make it easy to clean.
Maintenance and Long-Term Care
One of the best features of a chip-enhanced floor is how easy it is to maintain. Because the surface is sealed, dirt and liquids cannot penetrate the material. For routine cleaning, a simple sweep or a damp mop with a mild, pH-neutral cleaner is usually all that is required.
Avoid using harsh chemicals or abrasive scrubbing pads, as these can dull the topcoat over time. If the floor eventually loses its luster after several years of heavy use, you can often perform a “screen and recoat,” which involves lightly sanding the topcoat and applying a fresh clear layer to restore the original shine.
Conclusion
Decorative color chips are a versatile and effective way to upgrade any concrete floor. They offer a unique combination of aesthetic beauty and practical functionality, making them a top choice for both homeowners and business owners. By choosing the right color blend and following the proper application techniques, you can create a durable, slip-resistant surface that will look great for years to come.
