In Reply to: TV Studio floor covering posted by Jeff Porter on May 14, 1997 at 09:23:59:
Ardex makes self-leveling portland based concrete toppings that are often specified for TV studios. The studios need a flat, smooth and level surface that is concrete hard so the weight of the equipment can not cause the wheels to sink in, making it difficult to glide the cameras around smoothly. Check out two products at the Ardex site. K-500 can be applied 1/4 inch to 1 1/2 in thick and can be tapered down to 1/16 inch for thresholds. Mixed with pea gravel it can go up to 5 inches thick. K-500 can be coated with a quality floor paint/sealer (see recommendations) in 24+ hours. SD-T is the "fast track" version and can be applied 1/4 inch to 2 inches thick. SD-T can be coated with recommended floor paint in about 2 to 4 hours. Prep, prime and let dry, pour the topping and let it cure, then cover with appropriate floor paint. Check out or download three instruction brochures at the Ardex site, http://www.ardex.com, "Substrate Prep", "K-500" and "SD-T" or give Ardex technical service a call at 412-264-4240, 8am to 5pm east coast time. I hope this will help you out.
