Markus Sadowski, president, Admatek, Pszczyna, Poland, found Wayne Sellon at the World of Concrete 2007 where he demonstrated decorative vertical concrete work at the Artistry in Decorative Concrete demonstrations. Sellon is the co-owner of Tajmawall, Temecula, Calif., with his business partner and son Morgan Sellon. Admatek already had trained others in decorative concrete methodologies in Poland, but wanted to add vertical applications to the offering. Wayne and Morgan traveled to Poland to provide training and worked alongside Admatek on a vertical wall residential project.
“Building in Poland in communist times often meant gray and square,” says Wayne Sellon. “The desire now is for a new and colorful look. People are very receptive to decorative concrete.” The residence in Poland used Flex-C-Ment products, Picayune, Miss., and a special tool made by Wayne Sellon for the job. The residence featured clay block walls that were wrapped with 4-inch insulating foam and then rasped. The walls were covered with a fiberglass net to receive a cementitious primer. Workers applied a Flex-C-Ment primer over the netting and followed that with a scratch coat colored with lamp black integral color. The next day the same color was mixed and applied to the portion to be carved. Then the wall received a layer of Flex-C-Ment, colored red and applied with a large pool trowel to create a flat vertical surface. Texture pads applied to the red coat while still in a plastic stage of set gave the Flex-C-Ment a textured appearance. The design of the pad left the same kind of cleat marks typically found on real brick. Then using 8-foot aluminum levels, workers began at the top to place guidelines for cutting the horizontal joints.
Wayne Sellon created a tool for the workers to cut five lines at once, which increased the workers' production rate. With the horizontal lines in place, levels then were used to establish the vertical lines. Workers executed the vertical lines by moving a half brick at a time to carve every other brick for the running bond pattern. The carved away red material revealed the dark gray underneath and looked like a mortar joint. To further antique the appearance and to individualize the bricks, workers came back to hand chip edges. Then they applied Flex-Seal Supreme water-based matte finish sealer to complete the project.
Poland has a tradition of using brick for home building, however, using a concrete application over 4 inches of foam for the outside walls increases the insulation value. Wayne Sellon says that the vertical concrete application is also a less expensive and a faster system.
Wayne and Morgan spent 12 days on the project, five of which involved training individuals through a language barrier. However, through careful observation and working side by side, the techniques were taught. “The connection to the people and the experience in Poland was mind expanding,” says Wayne Sellon. He adds that seeing someone's eyes light up with understanding was the greatest reward of all.
