A

Should be professionally cleaned and then repainted.

32
Q

How does the nature of the surface to be painted fact the quantity of paint needed?

A

An unfinished surface will absorb the first coat of paint. Masonry and block surfaces require more paint and labor than an equal surface of drywall. Some masonry surfaces must be prepared first with washing to prevent powdery deposits from forming, or with sanding to ensure adherence.

33
Q

What factors, other than the size of the area to be painted, affect the amount of labor that will be needed for a paint job?

A

The amount of labor needed for a paint job depends on whether the are is furnished or vacant, on the amount of trim, on the amount of high-access or inaccessible areas, and on whether sprayers can be used.

34
Q

What are some adjusting considerations in handling damage to exterior paint?

A

Normal wear and tear to exterior paint is not Covered. Adjusters should not pay claims for normal wear and tear and must carefully consider the condition of paint when it is damaged by a covered peril. When a loss requires repainting of the exterior of a structure, it may be necessary to paint the entire structure to maintain a consistent appearance.

35
Q

What prep work must be done before applying exterior paint?

A

All old paint that is peeling or blistering must be removed and the surface sanded. If the underlying woof is rotted, it must be replaced. If the wood is cracked or pitted, it must be filled and sanded.

Q

Sarah’s living room measures 1,211 square feet. Sarah knows that in order to have enough paint she needs to divide the total number of square feet by the number of square feet that one gallon of paint can cover and then multiply that figure by the cost of a gallon of paint. If the paint costs $18 per gallon, how much can Sarah expect to spend on paint?

A

1,211 square feet / 400 square feet = 3.03 gallons and when rounded to the next full gallon, Sarah will need 4 gallons x $18 per gallon = $72.

A

The ceiling 12 feet x 12 feet = 144 square feet and walls (12 feet + 12 feet + 12 feet + 12 feet) x 8 feet = 384 square feet. Walls + ceilings = 144 square feet + 384 square feet total 528 square feet. A sheet of drywall covers 32 square feet. 528 square feet divided by 32 square feet = 16.5 rounded to 17.

Q

What is the gross area method of estimating painting?

A

A labor and materials approach that ignores deductions for any opening in the walls less than 100 sq ft. The gross area method makes an allowance for the time needed to paint trim by including the area of the openings in the surface area to be painted.

61
Q

Explain the net area method of estimating painting.

A

Also a labor and materials approach. It differs from the gross area method in how it counts openings in the walls. Under the net area method, all openings are deducted to determine the actual square footage of the walls. Then an allowance for the openings is separately calculated based on actual measure for mat rials and allowing an appropriate multiple of labor time for various openings and trim.
