That speckled, multi-color look you see on most professional garage floors comes from a process called chip — or flake — broadcasting. It's more than decoration: how the chips are broadcast affects the floor's durability, slip resistance, and appearance. Here's how the chip broadcast process works and why it's central to a quality Katy garage floor.
What Chip Broadcasting Is
After the colored base coat is applied, the installer hand-broadcasts (literally tosses) decorative vinyl chips across the wet surface. The chips settle into the base, and once it cures they're locked into the floor. A clear topcoat then seals everything. The chips add color and depth, hide minor slab imperfections, and create the surface texture that gives the floor traction.
Broadcasting "to Refusal"
The gold-standard technique for garages is broadcasting to refusal — the installer keeps tossing chips until the surface literally can't hold any more and chips start bouncing off. This creates a fully saturated chip layer with almost no base color showing through. A full broadcast gives the richest look, the most consistent texture, and the best slip resistance, and it's what we recommend for nearly every garage.
Full vs. Partial Broadcast
A full (to-refusal) broadcast covers the base completely for maximum durability and a premium look. A partial broadcast leaves some base color showing for a lighter, more economical accent finish. For a hard-working garage floor, full broadcast is almost always the right call.
Scrape and Recoat
Once the base cures with the embedded chips, the floor is scraped and vacuumed to remove loose, unbonded chips and knock down any sharp edges. This step is what makes the finished surface smooth and uniform rather than rough. Skipping or rushing it leaves a gritty, uneven floor — a telltale sign of an inexperienced installer.
How Chips Add Slip Resistance
The slightly raised, irregular profile of a full chip broadcast breaks up the smooth coating surface and adds micro-texture underfoot. That texture improves traction, especially when the floor is wet — a real benefit in a garage where rain gets tracked in. For extra grip, a fine anti-slip aggregate can also be added to the topcoat.
Color and Design Flexibility
Chips come in countless pre-mixed blends and custom combinations, and the blend you choose sets the whole tone of the garage. Lighter blends brighten the space; darker, multi-tone blends hide dust and dirt between cleanings. Chip size also matters — larger chips read bold and hide imperfections, smaller chips give a fine, uniform look.
Why Technique Matters
Chip broadcasting looks simple but is genuinely a skill. Even coverage, correct timing while the base is still wet, broadcasting at the right angle, and thorough scraping all separate a flawless floor from a blotchy one. It's one of the clearest places where professional experience shows in the finished result.
The Finishing Touch
A well-executed chip broadcast, sealed under a UV-stable polyaspartic topcoat, is what gives a garage floor its signature look and lasting performance. Want to see chip blends in person?
