Containers of materials covered by a referenced specification number shall bear the specification number, type, and class of the contents. Deliver materials in sufficient quantity to continue work without interruption. Store and protect materials in accordance with manufacturer's instructions, and use within their indicated shelf life.

Materials shall be stored in an area specifically designated for that purpose, in accordance with manufacturer's recommendations, where temperatures will not be less than 10 degrees C (50 degrees F) or higher than 38 degrees C (100 degrees F). When hazardous materials are involved, adhere to special precautions of the manufacturer, unless precautions conflict with local, state, and federal regulations. Promptly remove from the site materials or incomplete work adversely affected by exposure to moisture or freezing. Store materials on pallets and cover from top to bottom with canvas tarpaulins.

1.4 JOB CONDITIONS

Do not apply elastomeric acrylic coating system components when the ambient and/or surface temperature is below 10 degrees C (50 degrees F) or above 43 degrees C (110 degrees F), if any surface moisture is present, when the dew point is within 3 degrees C (5 degrees F) of the surface temperature, or when there is a possibility of temperatures falling below 0 degrees C (32 degreesF) within a 24 hour period. Do not apply if weather conditions will not permit complete cure before rain, dew, fog or freezing temperatures occur. Do not spray apply if the wind velocity exceeds 16 kilometer per hour (10 MPH) without taking appropriate precautions to eliminate over-spray. Take all measures necessary to protect unrelated surfaces from coating over-sprays or spillage. Furnish all scaffolding and the necessary equipment to complete the work. Scaffolding shall comply with all requirements as to safety. Provide drop cloths and other forms of protection necessary to protect all adjoining surfaces to render them completely free of overspray and splashes. Any surfaces that have been damaged or splattered shall be cleaned, restored, or replaced.

If sealant is applied prior to sealer, a test must be conducted prior to installation to verify compatibility of the sealer and sealant. For interior application, provide ventilation or forced air circulation during and after interior application of sealer until any odor is no longer evident.
