Quartz Broadcast Flooring in Nairobi
Quartz broadcast
Coloured quartz, double broadcast · grouted, sealed and coved · ≈3 mm
Westlands, Nairobi
85 m² · restaurant kitchen
Quartz broadcast is the grip system. Kiln-fired coloured quartz is thrown into a pigmented resin to rejection, then again into a second clear coat (a double broadcast), so the aggregate sits packed shoulder to shoulder right through the build rather than sprinkled on the surface. A grout coat fills the voids between grains, and a topcoat closes it. Across Nairobi it goes into commercial kitchens, clinics and pool decks; the one above is an 85 m² restaurant kitchen in Westlands.
What you get is roughly 3 mm of aggregate-loaded floor that stays slip-resistant while it is wet, because the grip is structural. A textured topcoat wears smooth in the traffic line within a year or two. This does not: you would have to wear through three millimetres of quartz to lose it.
Why a kitchen stops using tile
Tile in a commercial kitchen fails at the grout. The lines hold grease and water, they harbour bacteria, and an inspector will find them before you do. A broadcast floor has no joints at all: it is poured continuous, coved 100 mm up the wall, and terminated into the drains, so the floor and the skirting are one piece of material.
It is the standard specification for kitchens, clinics, wash bays and vet theatres for exactly that reason, and it is the system we push hardest when a health inspection is the reason for the call.
Choosing your texture honestly
Texture is a dial, and it is a trade-off we would rather settle in front of you with samples than decide for you. A heavier broadcast and a thinner grout coat buy more grip and a floor that needs a deck brush or a scrubber-drier. A fuller grout coat gives a smoother floor that mops easily and gives less back underfoot when it is wet with fat.
We set the level to the room: fryer line and pot-wash heavy, dining side and corridors lighter. A wet-area quartz floor typically lands around R11. That rating is worth nothing if the cleaning regime cannot reach into the texture, so we specify the two together.
Where this system belongs
Specified for
- Commercial kitchens and pot-wash: grease and water together, with no grout line anywhere in the room.
- Clinics, labs and vet theatres: seamless, coved, and cleanable with the chemicals those rooms actually use.
- Pool surrounds, wash bays and ramps: anywhere people walk on a wet floor and the alternative is a warning sign.
Not specified for
- Living rooms and showrooms: the texture is the point, and it is not a finish you want barefoot. Take the decorative pour (system 01).
- Rooms cleaned only with a flat mop: a mop skates over texture. Without a brush or scrubber it will look dirty and be blamed on the floor.
- Steam-lanced cooker stations: once thermal shock is routine, urethane cement at 9 mm (system 03) is the right specification.

Fills the voids between the grains. How full it is, is how smooth the finished floor is.

Chemical-resistant topcoat, with the system coved 100 mm up the wall and cut into the drains.

Living with it
Deck brush or scrubber-drier, not a flat mop; the texture is what you are cleaning into. Alkaline degreaser on the fryer line, neutral cleaner elsewhere. Check the coving and drain edges monthly.
