Thorndown Grey Stain Blocking Primer 750ml

Thorndown Grey Stain Blocking Primer: For a flawless finish on all your timber projects, this high-performance primer is your essential first step. Its water-based formula effectively blocks tannin, stain, resin, and sap bleed on untreated softwoods and hardwoods, including pine, cedar, redwood, plywood, MDF, and hardboard. 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, this low-VOC primer is suitable for interior and exterior applications. Enjoy quick drying times - approximately one hour in good weather - and achieve excellent results with just one coat (though a second coat may be beneficial for exceptionally resinous or knotty woods). Available in a convenient 750ml pack size.
