Coo-Var Stain Lock Sprayable Primer is a water based multi purpose primer and sealer designed to be applied to stains on a variety of interior and exterior surfaces, helping to prevent the stain from bleeding through subsequent coats. It can also seal knots on wooden surfaces, preventing resin from affecting paint that is applied to the wood.
Touch dry in 1 hour and hard dry in 2 hours. Leave 2 to 4 hours before overcoating.
