<br />PAINTING 09 91 00 - 6
<br />c. Approved Equal BM, MAB, PPG.
<br />PART 3 - EXECUTION
<br />3.1 EXAMINATION
<br />A. Examine substrates and conditions under which painting will be performed for compliance with paint
<br />application requirements. Surfaces receiving paint must be thoroughly dry before paint is applied.
<br />1. Do not begin to apply paint until unsatisfactory conditions have been corrected.
<br />2. Start of painting will be construed as the Applicator's acceptance of surfaces and conditions within
<br />a particular area.
<br />B. Coordination of Work: Review other Sections in which primers are provided to ensure compatibility of
<br />the total system for various substrates. On request, furnish information on characteristics of finish
<br />materials to ensure use of compatible primers.
<br />1. Notify the Architect about anticipated problems using the materials specified over substrates
<br />primed by others.
<br />3.2 PREPARATION
<br />A. General: Remove hardware and hardware accessories, plates, machined surfaces, lighting fixtures, and
<br />similar items already installed that are not to be painted or provide surface-applied protection prior to
<br />surface preparation and painting. Remove these items, if necessary, to completely paint the items and
<br />adjacent surfaces. Following completion of painting operations in each space or area, have items
<br />reinstalled by workers skilled in the trades involved.
<br />B. Cleaning: Before applying paint or other surface treatments, clean the substrates of substances that could
<br />impair the bond of the various coatings. Remove oil and grease prior to cleaning. Schedule cleaning and
<br />painting so dust and other contaminants from the cleaning process will not fall on wet, newly painted
<br />surfaces.
<br />C. Surface Preparation: Clean and prepare surfaces to be painted according to the manufacturer's
<br />instructions for each particular substrate condition and as specified.
<br />1. Provide barrier coats over incompatible primers or remove and reprime. Notify Architect in
<br />writing about anticipated problems using the specified finish-coat material with substrates primed
<br />by others.
<br />2. Cementitious Materials: Prepare concrete, concrete masonry block, cement plaster, and mineral -
<br />fiber-reinforced cement panel surfaces to be painted. Remove efflorescence, chalk, dust, dirt,
<br />grease, oils, and release agents. Roughen, as required, to remove glaze. If hardeners or sealers
<br />have been used to improve curing, use mechanical methods of surface preparation.
<br />3. Use abrasive blast-cleaning methods if recommended by the paint manufacturer.
<br />4. Determine alkalinity and moisture content of surfaces by performing appropriate tests. If surfaces
<br />are sufficiently alkaline to cause the finish paint to blister and burn, correct this condition before
<br />application. Do not paint surfaces where moisture content exceeds that permitted in
<br />manufacturer's printed directions.
<br />5. Wood: Clean surfaces of dirt, oil, and other foreign substances with scrapers, mineral spirits, and
<br />sandpaper, as required. Sand surfaces exposed to view smooth and dust off.
<br />a. Scrape and clean small, dry, seasoned knots, and apply a thin coat of white shellac or other
<br />recommended knot sealer before applying primer. After priming, fill holes and
<br />imperfections in finish surfaces with putty or plastic wood filler. Sand smooth when dried.
<br />b. Prime, stain, or seal wood to be painted immediately upon delivery. Prime edges, ends,
<br />faces, undersides, and backsides of wood, including cabinets, counters, cases, and paneling.
<br />c. When transparent finish is required, backprime with spar varnish.
<br />d. Backprime paneling on interior partitions where masonry, plaster, or other wet wall
<br />construction occurs on backside.
