Haussmann’s Magnetic Paint [Blue] Highly flexible, this magnetic paint can be used on wallpaper and textiles, as well as plaster, masonry, concrete, gypsum board, and ceiling tiles, turning them into a magnetic surface. Water-based, with no smell and easy clean-up, it out-performs similar oil-based products. Highly effective after only two coats. Apply with a brush, roller or spray. Recoat after a minimum of 4 hours. After 24 hours apply your choice of top coat with no loss of the magnetic effect. Covers 8 - 12 m2 per litre.
