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.
Typically a relativehumidity of 75% to 80% is targeted for installation offloor coverings. Relative humidity probes can determinethe moisture profile from top to bottom in a slab, condi-tions below the slab, and can monitor the drying of aslab over time, leading to predictions of future moistureconditions.void using curing compounds on floorswhere coverings or coatings will be installed.â¢ Allow sufficient time for the moisture in the slab todry naturally while the floor is under a roof and pro-tected from the elements. Avoid maintenance and clean-ing operations that will wet the concrete floor.
