Very high levels of AST (more than 10 times normal) are usually due to acute hepatitis, sometimes due to a viral infection. With acute hepatitis, AST levels usually stay high for about 1-2 months but can take as long as 3-6 months to return to normal.
MFMA recommends the relative humidity level for a concrete slab for a non-glue-down maple floor system be 85% or lower and for glue down systems the concrete slab relative humidity level should be 75% or lower before installation.
Minimum floor temperature for coating is 55Â°F (13Â°C). Product should be applied when ambient/air temperature is 60-85Â°F (16-29Â°C). Concrete floors take a long time to warm up; make sure the previous day has also been at least 60Â°F (16Â°C) prior to coating. Do not apply if night time temperature is expected to drop below a low of 65Â°F (18Â°C). For best results, temperatures should not drop below 65Â°F (18Â°C) for 24-48 hours after applying the coating.
