Wash with mineral spirits and pretreat with a primer in accordance with SSPC Paint 27. Mix the pretreatment primer by adding one volume of acid component (diluent) to four volumes of resin component (base solution) slowly and with constant stirring. After mixing, use the material within 8 hours. Spray apply the pretreatment primer at a coverage rate of 250 to 300 square feet/gallon (of resin component) to give a dry film thickness of

0.3 to 0.5 mil. Small areas may be coated by brush or swab. Take care in spray application to avoid the deposition of dry particles on the surface.

Maintain a wet spray at all times by additional thinning with Normal Butanol ASTM D304. The acid component (diluent), over and above the amount prescribed above, are not to be used for thinning purposes. Surfaces to receive the first coat of paint after at least 1 but not more than 24 hours drying of the pretreatment primer film.

3.2 PAINT APPLICATION

3.2.1 General

The finished coating to be free from holidays, pinholes, bubbles, runs, drops, ridges, waves, laps, cracks, excessive or unsightly brush marks, and variations in color, texture, and gloss. Application of initial or subsequent coatings are not to commence until the Contracting Officer has verified that atmospheric conditions and the surfaces to be coated are satisfactory. Apply each paint coat in a manner that will produce an even, continuous film of uniform thickness. Edges, corners, crevices, seams, joints, welds, rivets, corrosion pits, and other surface irregularities to receive a stripe coat to ensure that they receive an adequate thickness of paint. Equip spray equipment with traps and separators and where appropriate, mechanical agitators, pressure gauges, pressure regulators, and screens or filters. Furnish air caps, nozzles, and needles as recommended by the spray equipment manufacturer for the material being applied. Airless-type spray equipment may be used only on broad, flat, or otherwise simply configured surfaces, except that it may be employed for general painting if the spray gun is equipped with dual or adjustable tips of proper types and orifice sizes. Airless-type equipment is prohibited for use in the application of vinyl paints.

3.2.2 Mixing and Thinning

Mix thoroughly, strain where necessary, and keep at a uniform composition and consistency during application. Add paste or dry-powder pigments specified at the time of use, with the aid of powered stirrers, incorporated into the vehicle or base paint in a manner that will produce a smooth, homogeneous mixture free of lumps and dry particles. Where necessary to suit conditions of the surface temperature, weather, and

SECTION 09 97 02 Page 13 method of application, the paint may be thinned immediately prior to use.

Limit thinning of not more than 1 pint per gallon of the proper thinner;

this limitation is not to be applied when more specific thinning instructions are provided. Bring paint that has been stored at low temperature up to at least 70 degrees F before being mixed and thinned, and temperature in the spray tank or other working container is not to fall below 60 degrees F during the application. Paint that has deteriorated in any manner that it cannot be restored to original condition by customary field-mixing methods is prohibited for use. Paint and thinner that is more than 1 year old will be resampled and resubmitted for testing to determine its suitability for application.

3.2.3 Atmospheric and Surface Conditions

Apply only to surfaces that are 5 degrees above the dew point temperature and are completely free of moisture as determined by sight and touch.

Paint is not to be applied to surfaces upon which there is detectable frost or ice. Except as otherwise specified, the temperature of the surfaces and air in contact with is not to be less than 45 degrees F during paint application nor apply paint if the surfaces can be expected to drop to 32 degrees F or lower before the film has dried to a reasonably firm condition. During periods of inclement weather, painting may be continued by enclosing the surfaces and applying artificial heat, provided the minimum temperatures and surface dryness requirements prescribed previously are maintained. Paint not to be applied to surfaces heated by direct sunlight or other sources to temperatures that will cause detrimental blistering, pinholing, or porosity of the film. Take daily sling-psychrometer readings before painting operations are commenced.

Maintain a daily log of the dew point determination and the time of the determination and submit.

3.2.4 Time Between Surface Preparation and Painting

Prime cleaned surfaces or prepared for painting as soon as practicable after such preparation has been completed but in no case longer than 6 hours, and in any event, prior to any deterioration of the prepared surface.

3.2.5 Method of Paint Application

Apply paint by brush or spray to ferrous and nonferrous metal surfaces.

Apply a stripe coat to ensure adequate coverage of edges, corners, crevices, pits, rivets, bolts, welds, and similar surface irregularities.

Other methods of application to metal surfaces will be subject to the specific approval of the Contracting Officer. Whenever application of paint by a specific method to a surface is permitted or directed, it is understood that all areas inaccessible to that method will be coated by alternate means.

3.2.6 Coverage and Film Thickness

Film thickness or spreading rates as specified. Where spreading rate is not specified, apply paint at a rate normal for the type of material being used. In any event, the combined coats to completely hide base surface and the finish coats to completely hide undercoats of dissimilar color.

SECTION 09 97 02 Page 14

Measurement on Ferrous Metal: Where dry film thickness requirements are specified for coatings on ferrous surfaces, make measurements with a gage qualified in accordance with paragraph "Coating Thickness Gage Qualification." Calibrate and use in accordance with ASTM D7091.

Calibrate using plastic shims with metal practically identical in composition and surface preparation to that being coated, and of substantially the same thickness (except that for measurements on metal thicker than 1/4 inch, the instrument may be calibrated on metal with a minimum thickness of 1/4 inch). Frequency of measurements to be as recommended for field measurements by ASTM D7091 and reported as the mean for each spot determination. Calibrate the instruments or calibration verified prior to, during, and after each use.

3.2.7 Progress of Painting Work

Where painting on any type of surface has commenced, the complete painting operation, including priming and finishing coats, on that portion of the work completed as soon as practicable, and without prolonged delays.

Sufficient time to elapse between successive coats to permit them to dry properly for recoating, and modify this period as necessary to suit adverse weather conditions. Paint will be considered dry for recoating when it feels firm, does not deform or feel sticky under moderate pressure of the finger, and the application of another coat of paint does not cause film irregularities such as lifting or loss of adhesion of the undercoat. All coats of all painted surfaces to be unscarred and completely integral at the time of application of succeeding coats. At the time of application of each successive coat, clean undercoats of dust, grease, overspray, or foreign matter by means of airblast, solvent cleaning, or other suitable means. Undercoats of high gloss will, if necessary for establishment of good adhesion, be scuff sanded, solvent wiped, or otherwise treated prior to application of a succeeding coat.

3.2.8 Contacting Surfaces

Paint bolted connection faying surfaces surfaces with primer only before connecter installation. Unless otherwise specified, corrosion-resisting metal surfaces (i.e., stainless steel, aluminum bronze, and galvanized surfaces) are not to be painted.

3.2.9 Drying Time Prior to Immersion

Minimum drying periods after final coat prior to immersion at least 3 days.

Minimum drying periods to increase twofold if the drying temperature is below 65 degrees F and/or if the immersion exposure involves considerable abrasion.

3.2.10 Protection of Painted Surfaces

Where shelter and heat are provided for painted surfaces during inclement weather, maintain such protective measures until the paint film has dried and discontinuance of the measures is authorized. Items that have been painted are not to be handled, worked on, or otherwise disturbed until the paint coat is fully dry. Store all coated metalwork out of contact with the ground in a manner and location that will minimize the formation of water-holding pockets; soiling, contamination, and deterioration of the paint film, and damaged areas of paint on such metalwork will be cleaned and touched up without delay.

3.2.11 Vinyl Paints

3.2.11.1 General

Spray apply vinyl paints, except that areas inaccessible to spraying will be brushed. All of the vinyl paints require thinning for spray application except the zinc-rich vinyl paint (Formula VZ 108d) which will normally require thinning only under certain weather conditions. Thinners for vinyl paints as follows:

APPROXIMATE AMBIENT AIR TEMPERATURE

(Degrees F)

Below 50 MEK

50 - 70 MIBK

Above 70 MIAK

The amount of thinner will be varied to provide a wet spray and avoid deposition of particles that are semidry when strikes the surface. Vinyl paints are not to be applied when the temperature of the ambient air and receiving surfaces is less than 35 degrees F nor when the receiving surfaces are higher than 125 degrees F. Each spray coat of vinyl paint consists of a preliminary extra spray pass on edges, corners, interior angles, pits, seams, crevices, junctions of joining members, rivets, weld lines, and similar surface irregularities followed by an overall double spray coat. A double spray coat of vinyl-type paint consists of applying paint to a working area of not less than several hundred square feet in a single, half-lapped pass, followed after drying to at least a near tack-free condition by another spray pass applied at the same coverage rate and where practicable at right angles to the first. Rivets, bolts, and similar surface projections to receive sprayed paint from every direction to ensure complete coverage of all faces. Fill pits, cracks, and crevices with paint insofar as practicable, but in any event, cover all pit surfaces and seal off all cracks and crevices against the entrance of moisture.

Keep fluid and atomization pressures as low as practicable consistent with good spraying results. Unless otherwise specified, apply not more than

2.0 mils, average dry film thickness, of vinyl paint per double spray coat. Except where otherwise indicated, an undercoat of the vinyl-type paint may receive the next coat any time after the undercoat is tack-free and firm to the touch, provided that no speedup or delay in the recoating schedule will cause film defects such as sags, runs, air bubbles, air craters, or poor intercoat adhesion. Neither the prime coat nor any other coat will be walked upon or be subjected to any other abrading action until it has hardened sufficiently to resist mechanical damage.

3.2.11.2 Vinyl Zinc-Rich Primer

Mix primer combining components A, B, and C. Mix in accordance with label instructions. After mixing, keep paint covered at all times to avoid contamination and apply within eight days after mixing. When the ambient and steel temperature is below 80 degrees F, the paint normally would not require thinning; however, paint at all times contain sufficient volatiles (thinners) to permit satisfactorily atomized, to provide a wet spray, and to avoid deposition of particles that are semidry when they reach the surface. Stir paint continuously during application at a rate that will

SECTION 09 97 02 Page 16 prevent the zinc dust from settling. When spraying is resumed after any interruption of longer than 15 minutes, vigorously whip entire length of the material hose until any settled zinc is redispersed. Long periods of permitting the paint to remain stagnant in the hose will be avoided by emptying the hoses whenever the painting operation is suspended for more than 1 hour. Keep paint hoses as short as practicable, preferably not more than 50 feet in length. Equipment used for spraying zinc primer is not to be used for spraying other vinyl-type paints without first being thoroughly cleaned, since many of the other paints will not tolerate zinc contamination; type of hot spray is prohibited for use. An average dry film thickness of up to 2.5 mils may be applied in one double-spray coat.

Not more than 8 days will elapse after application of a VZ-108d zinc-rich coat before receiving a succeeding coat. Authorization to extend the recoat time where prime-painted pieces are assembled, bolted and retensioned three weeks after initial tensioning such that retensioning can be accomplished prior to subsequent coats of paint. Ensure primed surfaces to receive paint are clean and dry prior to application of successive coats. Use water to remove dust and detergent to remove grease and oil.

3.2.11.3 Vinyl Paints

Vinyl Paints (Formula V-766e) is a ready-mixed paint designed to be spray applied over a wide range of ambient temperatures by field thinning with the proper type and amount of thinner. For spray application, thin as necessary up to approximately 25 percent (1 quart per gallon of base paint) with the appropriate thinner; when ambient and steel temperatures are above normal, up to 40-percent thinning may be necessary for satisfactory application.

3.3 PAINT SYSTEMS APPLICATION

3.3.1 Surface Preparation

The method of surface preparation and pretreatment shown in the tabulation of paint systems is for identification purposes only. Accomplish cleaning and pretreatment of surfaces prior to painting in accordance with detailed requirements previously described.

3.3.2 System No. 3-A-Z

Spray applied to an average dry film thickness of a minimum of 6.5 mils for the completed system, and the thickness at any point is not be less than

5.5 mils. The dry film thickness of the zinc-rich coat at approximately

2.5 mils. Specified film thickness, including the prescribed total, attained in any event, and apply any extra coats needed to attain specified thickness at no additional cost to the Government. Attaining specified film thickness in fewer than the prescribed number of coats or spray passes will be acceptable provided heavier applications do not cause an increase in pinholes, bubbles, blisters, or voids in the dried film and also provided that not more than 2.0 mils (dry film thickness) per double spray coat nor apply more than 1.0 mil per single spray pass of nonzinc paint at one time.

SECTION 09 97 02 Page 17

3.4 PROTECTION OF AREAS AND SPACES NOT TO BE PAINTED

Prior to surface preparation and coating applications, remove, mask, or otherwise protect, hardware, machined surfaces, radiator covers, plates, lighting fixtures, and other such items not to be painted. After paint cures, reinstall removed items and cleanup any spills or spatters. Correct any paint drips, areas missed, and paint limit lines.
