Maxwell's Equations. We now have the tools to derive some very useful relationships between thermodynamics variables. Maxwell's equations are based on the same principle as was Euler's test for exact differentials, namely that mixed second derivatives of nice functions must be equal.
Depending on the stain technique it can take anywhere from 2 to  24-hours for the stain to dry. For cabinets, you should wait the  entire 24-hours to make sure the stain is â¦not still tacky and to  prevent smudges on the finish.
Long story short: it varies. Depending on how much stain you put on, it can be anywhere between 2 and 24 hours. We stained our counter height kitchen table before putting a coat of black paint over it, and that was dry enough to paint over (we wanted the two to mix. Unconventional, yes but it turned out really cool!). That only took about two hours to dry.
