MavTop — decorative broadcast
Quartz broadcast (UQB) and epoxy flake broadcast (EFB / EFB-DB). Broadcast physics — density, reject rate, and aggregate grade — is where reps either sound like installers or get caught guessing.
- Separate quartz broadcast from flake broadcast by look and by slip performance
- Explain what a double broadcast actually is
- Define reject rate and use it to drive a material takeoff
Broadcast is physics, not decoration
MavTop is Maverick's decorative broadcast line: quartz broadcast (UQB) for slip-resistant colored quartz floors, and epoxy flake broadcast (EFB, and EFB-DB for the double broadcast) for retail, food-processing, and locker-room floors. The finished look and the slip rating both come from what is thrown into the wet film and how densely it lands. EFB-DB is defined by two separate flake broadcasts — one into the fresh basecoat and one into the fresh grout coat — which is what buys full color hide.
Spec'ing the broadcast
| Customer is asking for | What you spec | Why |
|---|---|---|
| Decorative dot look, showroom or retail clean look | MavTop EFB | Flake gives the smoother decorative appearance. |
| Heaviest visual density and full opaque color show | MavTop EFB-DB | The double broadcast is what buys full hide. |
| Aggressive slip resistance with full opaque color | MavTop UQB | Colored quartz delivers both the slip and the hide. |
| Wet-service kitchens, food walk lanes, locker rooms | MavTop UQB | Quartz is coarser and more slip-forgiving at any topcoat build — a foot-slip is a claim. |
| More visible texture on a quartz floor | A coarser aggregate grade | Texture is driven by aggregate diameter — moving from 20-40 to 16-20 mesh lifts the peaks. Not by more media, not by thinning the sealer. |
Say it out loud, then check yourself
- 01Hand chicken-feeding vs spraycaster — which is denser, and why?
The spraycaster. Hand feeding depends on gravity and the applicator's rhythm, so density varies by pass and with fatigue. A spraycaster launches flake horizontally at consistent velocity, so more particles reach the wet film with better distribution before the surface tacks. Density equals broadcast rate times available wet time — the spraycaster wins on both.
- 02When do you spec UQB over EFB?
When the aesthetic is a quartz color blend and slip is a hard requirement. Quartz gives a coarser, more slip-forgiving surface at any topcoat build; flake gives the smoother decorative dot look. Quartz for wet-service kitchens, food-processing walk lanes, and locker rooms; flake for showroom, retail, and clean-look service floors.
- 03Define reject rate and lay-in rate. Which drives the takeoff?
Lay-in rate is the broadcast that stays embedded in the wet film. Reject rate is the broadcast that does not stick and gets swept up after cure. Reject rate drives the takeoff — you order lay-in plus reject to hit target density on the finished floor. Hand chicken-feeding typically rejects 30 to 50%.
- 04Hospital cafeteria wants the decorative dot look AND wet-spill slip resistance.
Spec MavTop UQB. The quartz grade is where the wet-service slip rating comes from — flake can deliver the look, but quartz defends the slip claim. If the customer will not give up the flake aesthetic, spec an EFB-DB body with a MavSeal HTU wear-filled satin topcoat to buy back slip resistance at COF wet 0.70.
Takeaways
- EFB broadcasts decorative flake. UQB broadcasts colored quartz. Mixing those up in front of a customer is costly.
- Texture comes from a coarser aggregate grade — not from more media and not from thinning the sealer.
- Reject rate drives the takeoff. Hand-feeding rejects 30–50% of the media.
