rmstrong Biome Solstice (ST131) is the lightest of the three Tellus colors, a design Armstrong describes as rustic. At 25-29% light reflectance it is well lighter than Midsummer (10-14%) and Polar Night (0-9%), and its swatch appears warm honey brown with knotty, varied graining.
On-grade and below-grade slabs need extra care. The concrete should sit directly on an intact vapor retarder meeting ASTM E1745, be wet-cured rather than treated with spray-on curing compounds, and pass moisture, pH, and bond testing. Below grade, S-995 is limited to 90% RH and pH 9, compared with 95% RH on or above grade, while S-1000 is rated to 100% RH.
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.
