Our Concrete Product Group guys are excited because we’re coming out with “White” ColorHard. We’re coming out with “Black,” too, but it’s “White” that seems to be making their day.
Evidently, nobody has a white surface-applied pigment for concrete that also hardens and densifies concrete like ColorHard. I went online to try to verify the veracity of this claim, but couldn’t find any other surface-applied white. I did find some integral white coloring, but that’s a different beast, with its own advantages and drawbacks.
The way ColorHard works is that you mix a 4-oz. packet with a gallon of Consolideck LS (lithium-silicate) hardener/densifier. Then you put it on the concrete with a pump up sprayer, and spread it with a micro-fiber applicator. After an hour or so, you put a protective treatment on it — LSGuard if it’s indoors and you want glossy, or Saltguard WB (water-based) if it’s outside and you want it water- and de-icing salt repellent.
In any case, the concrete, sustainable already, is now colorful, and more sustainable because it’s harder, denser and resistant to stains and abrasion.
I’m told our White will be a great alternative to white VCT in hospitals, pharmacies and other places needing a clean, sterile or simply cheerful look. It’s not planned for release for another month or so, but looks like it’s already planned to go down on 80,000 square feet of white Portland Cement concrete at a new Woodman’s Food Market in Madison, Wis.
Here’s a shot of the mockup they did for the Woodman’s project — photo by Shawn Wardall, Specialized Construction Services inc. The strip in the foreground of the panel is the white cement concrete with several types of protective treatments, but no White ColorHard.
Here’s another shot from the other direction, in different light.
I believe the procedure will be — grind to a 200 resin diamond finish, apply the ColorHard, burnish with diamond pads, and put glossy, lithium-silicate containing LSGuard protective treatment on it.
That’s all I know for now, though I expect to get the gory details for a story in PROSOCO News when the project is done.
