Ready Seal Stain and Sealer for Wood is an oil-based, semitransparent stain and sealer in one. It is a unique blend of oils, quality resins and finely ground pigments that penetrate deeply to protect and preserve the wood from the elements. Ready Seal semi-transparent stains enhance the natural beauty of the wood by reacting with its natural characteristics and allowing the texture and grain of the wood to remain visible. Ready Seal may be used on any exterior wood project. Ready Seal is effective on all types of wood and shows excellent results on premium-grade lumbers, including Western Red Cedar, Douglas Fir, Cypress, Spruce and Redwoods.
