If you've ever walked into a high-end commercial garage or a luxury car showroom and admired that textured, granite-like floor, you were looking at a full broadcast flake floor system. It's not just paint with some glitter tossed on, it's a multi-layered armor designed to hide dirt, provide massive grip, and last a lifetime. Here is exactly how to install it like pros.
A full broadcast means applying a liquid epoxy base coat and tossing epoxy flakes onto it until the wet epoxy is 100% covered and can no longer absorb flakes (this is called broadcasting "to refusal"). Once dry, the excess flakes are scraped off, and a clear Polyaspartic topcoat will be applied to lock them in, creating a seamless, slip-resistant, and incredibly durable floor.
Why this is the ultimate garage floor system
There's a reason contractors push flake systems. Aside from looking fantastic, they solve almost every problem a concrete slab has:
- It Hides Everything: The dense, chaotic pattern of the flakes acts like camouflage. Minor concrete divots, dust, and even dropped screws practically vanish.
- Built-in Grip: The overlapping vinyl chips create a micro-texture. When sealed with a topcoat, it provides an "orange peel" finish that is highly slip-resistant, even when wet.
- Impact & Chemical Armor: Because you are building a floor with a primer, a thick epoxy base, a layer of vinyl, and a polyaspartic shell, you get extreme resistance to hot tires, dropped tools, and oil spills.
The Pro Materials Checklist
Don't try to build a 20-year floor with a 1-part water-based kit from a hardware store. A true flake system requires a dedicated chemical stack. Here is what you need:
1. The Roots
Moisture Seal Epoxy Primer. Penetrates the concrete pores to stop moisture vapor and prevent the whole system from peeling up later.
View Primer2. The Glue
Colored Epoxy Base Coat. A thick, solid-color layer that acts as the background color and the sticky adhesive that grabs the flakes.
View Epoxy Base3. The Armor
Polyaspartic Topcoat. A crystal-clear, UV-stable layer that locks the flakes down forever and resists hot tire pickup.
View Topcoat* You will also need 1/4" Decorative Vinyl Flakes (calculate roughly 10-15 lbs per 100 sq.ft. for a full broadcast), spike shoes, squeegees, and lint-free rollers.
The 6-Step Installation Guide
Installing a flake floor isn't rocket science, but it does require timing and hustle. Read through these steps before you ever open a bucket of resin.
Step 1: Surface Preparation (The Make-or-Break Step)
We say it all the time: your floor is only as strong as the concrete it's stuck to. You must open the pores of the slab. Rent a mechanical concrete grinder with a vacuum attachment. Grind the floor until it feels like medium-grit sandpaper. Vacuum the dust obsessively—if you think it's clean, vacuum it one more time.
Step 2: Applying the Primer
Mix your Pourla Epoxy Primer and roll it out. The concrete will likely drink it up. This step creates a permanent root system into the slab and stops trapped air from bubbling up (outgassing) into your final finish. Let it cure until it's safe to walk on.
Step 3: Laying the Epoxy Base Coat
This is your color coat and your "glue". Mix your colored Pourla Epoxy Floor Top Coat. Pour it in ribbons, spread it with a squeegee, and back-roll it to get an even thickness. Work in sections, because you need to throw the flakes while this layer is still wet and sticky!
Step 4: The Full Broadcast (Making it Rain)
Put on your spiked shoes so you can walk on the wet epoxy. Grab handfuls of your vinyl chips and throw them up into the air, letting them cascade down evenly like snow. Keep tossing until the floor is completely buried and you cannot see a single drop of the colored epoxy underneath. This is "broadcasting to refusal." Leave the room and let it cure hard overnight.
Step 5: Scraping and Cleanup
Once the epoxy is fully cured, the floor will look like a messy pile of chips. Take a wide, flat metal floor scraper and vigorously push it across the entire floor in multiple directions. This knocks down any flakes that are sticking straight up. It will sound loud and crunchy—that's normal! Use an industrial vacuum or a leaf blower to remove all the loose, un-glued flakes.
Step 6: Applying the Clear Topcoat
Now for the magic. Mix your Pourla UltraShield Polyaspartic. Pour it out and roll it over the scraped flakes. As the clear liquid hits the flakes, the colors will instantly pop and gain insane depth. This topcoat cures fast, locks the chips permanently in place, and provides a showroom-level gloss that won't yellow in the sun.
Frequently Asked Questions
How many pounds of flakes do I need for a full broadcast?
To achieve a true "full broadcast to refusal" where no epoxy base coat shows through, you should plan to use 10 to 15 lbs of decorative flakes per 100 square feet. It's always better to order a little extra—you can simply sweep up and save the un-stuck flakes during the scraping step.
Can I skip the primer and just use the base coat?
We highly advise against it. Skipping the primer is the #1 cause of peeling floors down the road. A dedicated primer is thinner than a base coat; it is designed specifically to soak into the concrete pores and seal them. This stops moisture vapor from pushing the floor up and prevents air bubbles from ruining your base coat.
Will a flake floor be too rough to walk on barefoot?
Not if you do step 5 correctly! By vigorously scraping the floor in multiple directions after the base coat cures, you knock off all the sharp, vertical edges of the flakes. Once you roll the thick polyaspartic topcoat over it, the floor feels like the textured skin of an orange—comfortable for bare feet, but with enough grip to prevent slipping.
