Plastering laths are about 1 1/2 inches wide, 1/4 inch thick, and usually 4 feet long, the studding being generally placed 12 or 16 inches on centers, so that the ends of the lath may be nailed to them. The laths are usually set from 1/4 to 3/8 inch apart, requiring about 1 3/4 or 1 1/2 four-foot laths, respectively, to cover 1 square foot.
For a fair grade of work, a man will lay on an average about 15 bunches, or 1,500 laths, per day, while a rapid workman will put on about 2,000 laths. The cost of nailing up laths will be from 18 to 25 cents per bunch, or $1.80 to $2.50per thousand, being about equal to the cost of the laths and nails.
