MDF Window Sill Board White Primed

A white pre-primed MDF window sill board for tradespeople, delivering a paint-ready finish and dependable on-site efficiency.

Made from FSC-certified MDF, it resists moisture and warping to keep window reveals neat. It’s available in four widths: 219 mm, 244 mm, 269 mm and 295 mm, with a 25 mm thickness to fit most openings and provide solid support.

The white finish is pre-primed and twice sealed, removing the need for on-site priming; simply light sand and apply your final topcoat. The bullnose edge adds a refined architectural detail that suits both period property renovations and contemporary builds.

Ideal for renovators, housebuilders and tradespeople who value on-site efficiency, durability and a finish ready for topcoat.
