Graphic Concrete Ltd. has developed concrete surface retard membranes. They print surface retarder in pre-planned places on one side of the impermeable membrane. In this way, it is possible to produce etched concrete surfaces, partly etched surfaces and other structured etched concrete surfaces. The unique technology enables a cost effective and high quality production of textures, raster patterns, repeated patterns, or even sharp images, works of art or written text on a concrete surface. The use of pure membrane without any surface retard produces velvet pure cast surfaces. [via Graphic Concrete.]
