Thorndown White Stain Blocking Primer 2.5L

Achieve a flawless finish on your timber projects with Thorndown White Stain Blocking Primer. This superior water-based primer effectively prevents tannin and stain penetration, eliminating resin bleed and sap stains. Ideal for use under Thorndown's UV clear and translucent wood tones, as well as semi-opaque colours such as Golden Somer, Rowan Berry Red, and Sundowner Orange, it's suitable for all untreated softwoods and hardwoods, including pine, cedar, redwood, plywood, MDF, and hardboard. Low in VOCs, this primer is perfect for both indoor and outdoor applications. Enjoy a quick one-hour drying time in ideal conditions (one coat generally suffices, however, a second coat may be beneficial for highly resinous or knotty wood). This 2.5L pack delivers professional results with ease.
