a Chalkboard for Use
boards and washed boards should be "chalked in"
with the side of a piece of chalk. All chalkboards usually
produce "ghost" marks unless completely chalked
in. When the chalkboard has been whitened, wipe the board
with a cloth or with a felt eraser. Chalkboards in a "ready
to use" condition should be gray. Do not use water
or chalkboard solutions on the board. Chalkboards have a
porous surface, and when mixed with water, the binding agent
in chalk creates a paste, which clogs the pores and creates
a buildup. Liquids can also have a pitting effect on chalkboards.
