The priming..is the same for wood, plaister, stucco, and stone; but for paper and canvas, which are made rotten by oil, the priming must be of size..For small works, primed canvas may be obtained from the colourmen. Dryers are requisite in priming as they dispose the upper painting to dry quicker and unite better. Sponging with water previous to the applying each coat of paint disposes it to work and unite better, and in work exposed to the sun prevents blistering.
