White Stain Blocker prevents stains and discolouration of your work while and after you have been painting. As most wood contains tannin these brownish or tan discolourations can occur when the paint is applied over just wood and old layers of paint. Especially oak, redwood, cedar, and mahogany, or over knots in certain other wood species show this brown tannin stain problems.
