Coloured quartz
The grip that is structural, because it goes all the way through
Quartz is the same idea as flake taken considerably further. Where flake is about half a kilo a square metre, quartz is around ten times that, and the floor stops being a coating with something in it and becomes an aggregate-loaded build about 3 mm thick.
It is kiln-fired and resin-coated, which is why it holds colour and why it bonds rather than sits there. And it goes down twice.
Why there are two broadcasts
The first broadcast goes into the pigmented base coat to rejection. The second goes into a clear coat laid over the first, and it is what fills the gaps the first one left. Packed shoulder to shoulder through the whole build, the grains are load-bearing.
That is what "double broadcast" means and it is the line worth checking on a quote, because a single broadcast costs roughly half as much and looks identical on handover day.
The grip does not wear off
A textured topcoat gives a floor grip by putting texture on the surface, and the traffic lane polishes smooth within a year or two. A quartz floor has the same aggregate at 2 mm down as it has at the surface, so wearing the grip off means wearing through 3 mm of quartz.
This is the entire reason it exists, and why it goes in kitchens, pot-wash rooms, clinics and pool surrounds rather than anywhere that just wants a hard floor.
Texture is a dial, and it is your dial
A heavier broadcast with a thinner grout coat grips more and needs a deck brush or a scrubber-drier to clean. A fuller grout coat mops easily and gives less back underfoot when the floor is wet with fat.
We would rather settle that in front of you with samples than pick it for you, because the people who have to clean it every night are the ones who live with the answer.
How to tellA quartz floor stands about 3 mm proud at a doorway; you can see the step. If it measures the same as a plain epoxy floor at 2 mm, it had one broadcast instead of two, and the grip will polish off it inside a year of trolley traffic.
What to ask
Ask whether the broadcast is single or double, and measure the step at a doorway on handover. About 3 mm is a double broadcast. Level with the floor next door is not.
