Layering colors
When more than one stain color or concentration is
sprayed simultaneously or wet-to-wet, the various chemicals
compete for dominance. This application of various colors
from multiple sprayers results in areas where each stain color
develops or new colors blend from the convergence. If the
various colors were all poured together and sprayed from a
single sprayer, the outcome would simply be one color with
the typical multitonal effect.
Similarly, spraying water during the application stage
changes the color concentration with a phantom effect.
Take notice of the volume of stain applied with these
advanced techniques, as product management can get tricky.
You do not want the stain fl owing through or under the fl oor
plate and onto fl ooring not intended for stain.
Multiple colors
The stains may also be sprayed wet-to-dry. This technique
produces variant color, but with somewhat less organic
movement and color blending. Most applicators apply lighter
colors fi rst, then darker. However, applying lighter colors
after darker creates surprisingly nice effects. Greens, tans
and blues have striking impacts on black stain. (One of my
favorite ways to correct a problem area such as a drip of stain
or an area that’s too dark is to carefully apply a tan stain on
the drip. This will usually soften the spot and often eliminate
the problem altogether. Of course, I test an inconspicuous area
fi rst.)
