Histor Blackboard Paint

Histor blackboard paint, 1 L, for turning a wall, a door or a board into a chalk surface. Supplied by Sigma Coatings Malta alongside the Sigma range.

• Check before ordering: let it cure fully — days, not hours — then condition it by rubbing the flat of a chalk stick over the whole surface and wiping off. Skip that and the first thing written on it never fully erases.
