I have read that for paint the solids content indicates something about the quality of the paint in the sense that higher solids probably means fewer coats required.
Is this also the case for stains? Since stains are intended to be translucent I could imagine that the solids content could correlate with the darkness of the color, for instance, and have nothing to do with how well the finish will wear or age.
As an example, the Bona Drifast technical data sheet says:
Solids – 35-47%
and the Minwax TDS states
% Solids: 40.0-45.6
Aassuming the solids content is a measure of quality, what's a reasonable minimum value to have confidence the stain will hold up over time (say, 10-20 years)?
(All else being equal... obviously there are other factors which influence finish robustness as well.)
