manufacturer's written recommendations. Stripe coating shall be applied prior to the application of the subsequent coat. P. If the coating is applied by spraying, use suitable nozzles to provide an adequate supply of air within the proper pressure range to the liquid in the container and to the atomizing nozzle, all as recommended by the coating and equipment manufacturers as being best suited or necessary for the production of good work. All necessary precautions must be taken to avoid spray fallout on and the consequent damage to any works, improvements or properties either of the Owner or of other parties, wherever located. The Contractor shall be responsible for all damage resulting from drifting of the spray. Q. If applied by brushing, the coating shall be brushed on in one direction, and then smoothed in a direction at right angles thereto, so as to produce as uniform thickness of coating and as complete a coverage as possible. Such two -directional brushing shall be considered as "one coat" within the meaning of these Specifications. R. Finish coat shall be uniform in color and sheen without streaks, laps, runs, sags or missed areas. S. Remove spatter and droppings after completion of coating. 3.05. ENVIRONMENTAL CONDITIONS A. Proceed with surface preparation and coating application only when air and surface temperatures are above the manufacturers recommended minimum surface temperature and below 100 degrees F, and surface temperature is at least 5 degrees above wet bulb air temperature reading. Coating shall not be applied to dusty, wet, or damp surfaces, and shall not be applied in rain, snow, fog or mist, or when relative humidity exceeds 85 percent. No coating shall be applied when it is expected that the relative humidity will exceed 85 percent or when the air temperature will drop below 40 degrees F within 8 hours after the application of the coating. If working conditions are questionable, the Engineer shall make the decision and the Contractor shall accept Engineer's interpretation as final and binding. B. Provide fans, heating devices, or other means recommended by coating manufacturer to prevent formation of condensate or dew on surface or substrate, coating between coats and within curing time following application of last coat. C. Provide adequate continuous ventilation and sufficient heating facilities to maintain minimum 45 degrees Fahrenheit for 24 hours before, during, and 48 hours after application of finishes. D. No surface preparation or coating application work shall be done under unfavorable weather conditions, unless the work is adequately protected, and then only with the specific approval of the Engineer and inspection and approval by the Owner's representative. E. The Owner's representative intends to monitor environmental conditions including air temperature, steel temperature, dewpoint and relative humidity to ensure Contractor's compliance with the listed conditions.
