I got to stand in as still photographer today for our Graphic Designer Stephen Falls, who usually does the shooting around here.
We’re making a video about Consolideck ColorHard application on outside concrete flatwork. ColorHard is a water-based colorant for concrete flatwork indoors and out — concrete that’s not going to be polished. You mix 4 ounces of it with a gallon of Consolideck LS (lithium-silicate) Hardener/Densifier, to make a treatment that hardens, densifies and colors your indoor floor or outdoor flatwork in one easy step.
So I’m guessing it’s going to be a short video.
Joe Reardon, from our Concrete Products Group; and Lab guys Tom Stalnaker, Chris Moore and Brad Oleneck performed as cast and crew, while our multimedia specialist John Young captured it all on digital video.
I’m writing about this in “Green Journey,” because ColorHard and LS are environmentally friendly, and LS promotes sustainability by making concrete more durable and longer-lasting. In addition to being water-based, they’re low-odor and non-toxic.
“What if you get it on your hands?” I asked Tom Stalnaker, our Lab Manager. He shrugged. “Wash it off,” he said. “It won’t hurt you.”
And imho, concrete itself is just another way to spell “sustainable.”
They applied ColorHard — one of our “coffee-themed” colors, Light Roast — to a raw-materials delivery area in back of the plant. Joe Reardon used a pump-up sprayer to put the ColorHard down, while Chris Moore broomed it out for uniformity. They did two coats, separated by an hour’s dry-time. Joe was miked-up and did some narration while they worked.
Courtney Murdock, our project testing director, came out to watch and enjoy the pleasant weather, so I got her to display a 4-ounce packet of ColorHard.
Right after the second coat dried, the guys treated the flatwork with Consolideck Saltguard WB (water-based). Saltguard WB is a breathable, penetrating water and salt repellent that adds to the sustainability of concrete. Our climate offers plenty of potential for destructive freeze-thaw and wet-dry cycling. But if you can keep the water out, you keep out the problems water carries.
That includes the problem of water-carried de-icing salt. Water carries salt down through the concrete to the rebar. The salt corrodes the rebar, which makes it expand, stressing the surrounding concrete. In a climate like this one, in Lawrence, Kansas, home of the mighty Jayhawks, unprotected concrete can have its service life cut by two-thirds.
But between the hardening-densifying from the ColorHard application, and the water- and salt-repellent, I think our concrete is going to last — which is what sustainability is all about.
John says the video will probably be up on U-Tube in a few weeks.
