Armstrong Biome Malmo (ST282) has the same 50-54% light reflectance as Oslo, so the choice between these light Boreal colors comes down to tone. The swatch appears pale cream with soft, fine grain, warmer than Oslo's gray-white.
If the concrete is dusty, sweep or vacuum and roll on one coat of S-185 latex primer with a 3/8" nap roller. The recommended flooring adhesive can also serve as the primer, as long as it dries completely first. Grind rough concrete smooth, or, if it's too uneven for grinding, level it with a cementitious underlayment such as S-194, S-463, or S-466.
Finish: Diamond 10 Technology
Installation and warranty: Full-spread glue-down. The 30-year commercial limited warranty requires a recommended Armstrong adhesive, such as S-995 or S-1000, installed according to Armstrong's instructions.
