Advanced technology enables Beauti-Tone to formulate a unique resin blend of alkyd and acrylic. This blend enjoys the deep penetration benefit of an alkyd (oil), and the colourfast and mildew resistance benefits of an acrylic. This semi-transparent stain enhances the beauty of the woodgrain with 36 natural colours, including three pre-mixed: redwood, cedar, and walnut. Two coats are recommended for maximum protection, and no primer is required. Designated with the Home Owner's Guarantee.
