Less than 3 degrees C (5 degrees F) above dew point.

b.

Below 10 degrees C (50 degrees F) or over 35 degrees C (95 degrees F), unless specifically pre-approved by the Contracting Officer and the product manufacturer. Under no circumstances shall application conditions exceed manufacturer recommendations.

2.

Maintain interior temperatures until paint dries hard.

3.

Do no exterior painting when it is windy and dusty.

4.

Do not paint in direct sunlight or on surfaces that the sun will soon warm.

5.

Apply only on clean, dry and frost free surfaces except as follows:

a.

Apply water thinned acrylic and cementitious paints to damp (not wet) surfaces where allowed by manufacturer's printed instructions.

b.

Dampened with a fine mist of water on hot dry days concrete and masonry surfaces to which water thinned acrylic and cementitious paints are applied to prevent excessive suction and to cool surface.

6.

Varnishing:

a.

Apply in clean areas and in still air.

b.

Before varnishing vacuum and dust area.

c.

Immediately before varnishing wipe down surfaces with a tack rag.

3.2 inspection:

3.3 general workmanship requirements:

B. Application may be by brush or roller. Spray application only upon acceptance from the COR in writing.

C. Furnish to the COR a painting schedule indicating when the respective coats of paint for the various areas and surfaces will be completed. This schedule is to be kept current as the job progresses.

D. Protect work at all times. Protect all adjacent work and materials by suitable covering or other method during progress of work. Upon completion of the work, remove all paint and varnish spots from floors, glass and other surfaces. Remove from the premises all rubbish and accumulated materials of whatever nature not caused by others and leave work in a clean condition.

E. Remove and protect hardware, accessories, device plates, lighting fixtures, and factory finished work, and similar items, or provide in place protection. Upon completion of each space, carefully replace all removed items by workmen skilled in the trades involved.
