Conditioning a New Chalkboard
A new chalkboard is porous and you will want to prime or condition it before use, otherwise your first drawing could be there permanently. To condition a new chalkboard, lay a piece of this white chalk on its side and cover the board generously, first from top to bottom until covered and then from left to right until covered. Using a soft, dry cloth rub the chalk in well and then erase. Repeat.
