Plastering is measured by the square yard and is usually done in 2-coat or 3-coat work. In taking off plastering it is customary to deduct only one-half of the area of openings to allow for the extra work of plastering to the grounds.
In some localities no openings are deducted unless more than 7 yards in area, but in close figuring this is not generally followed.
Narrow strips, such as chimney breasts, if less than a foot wide, are generally called a foot. Round corners, beads, and arrises must be taken separately by the lineal foot.
Raking surfaces require additional work and should be taken at about one-half more than plain work. Circular or elliptical work should be charged at two prices and domes, groins, and intersecting soffits, at three prices. Cornices are taken by the square foot of girth with enrichments charged separately by the lineal foot.
Lathing. Lathing is generally included in the plasterer's price although put up by a different set of men. Lathing is estimated by the square yard or by the thousand laths, the price being $2.75 to $3.25 a thousand.
Labor. Two plasterers requiring one helper will do from 40 to 50 square yards of three-coat plastering, or 60 to 70 square yards of two-coat work, in a day of 8 hours, and 1,200 to 1,500 laths makes a day's work for one lather. 100 sq. yds. of lath and plaster will cost about as follows, for two-coat work:
1,500 laths at $4.75 per M
10 lbs. 3d. nails at $3.20 per cwt.
Labor on naths
10 bushels lime at . 48 per bu.
6 lbs. hair at .04
1 load sand
Plasterer 3 days at $5.00
Helper 1 1/2 days at $3.00
Cost of a square yard of two-coat work, $39.28 ÷ 100 = 39 to 40 cents.
This is a price which is on the increase and, while plastering is done in the country towns as low as 35 cents per yard it will not be safe to use this price any length of time.
Laths and putting on, as above
13 bush. lime at .48
8 lbs. hair at . 04
1 1/2 loads sand at $1.80
1 bbl. plaster Paris
Plasterer 4 days at $5.00
Helper 2 days at $3.00
Cost of a sq. yd. of three-coat work, $49.90 ÷ 100 = 50 cents.
Rules. In some portions of the country a set of rules has been adopted governing the valuing of plasterer's work which are in the main as follows:
Second. Returns of chimney-breasts, pilasters, and all strips of plastering less than twelve inches in width, measure as twelve inches wide; and where the plastering is finished down to the base, surbase, or wainscoating, add six inches to height of walls.
Third. In closets, add one-half to the measurement. Raking ceilings and soffits of stairs, add one-half to the measurement; circular or elliptical work, charge two prices; domes or groined ceilings, three prices.
Fourth. For each twelve feet of interior work done farther from the ground than the first twelve feet, add five per cent; for outside work, add one per cent for each foot that the work is done above the first twelve feet."
Stucco-work is generally governed by the following rules; viz., "Mouldings less than one foot girt are rated as one foot, over one foot, to be taken superficial. When work requires two moulds to run same cornice, add one-fifth. For each internal angle or mitre, add one foot to length of cornice, and, for each external angle, add two feet. All small sections of cornice less than twelve inches long measure as twelve inches. For raking cornices, add one-half; circular or elliptical work double price; domes and groins, three prices.
For enrichments of all kinds a special price must be charged. The higher the work is above ground, the higher the charge must be; add to it at the rate of five per cent for every twelve feet above the first twelve feet."
