• Do not apply if there is a threat of rain within 24 hours, or the period of time as identified in the manufacturer’s specification.

• Thirty (30) days must elapse before the Acrylic top coat is applied to ensure proper cure of the material. The Contractor will demobilize from the site between the application of the clay emulsion roof coating and the acrylic top coat.

3.3 Acrylic-based Top Coating

The Acrylic-based Top Coating must be rated for exterior use and be compatible with the existing substrate and primers. There shall be no thinning of the product to aid in application or extend coverage of material.

Application

• Pressure Wash roof with Cleaner compatible with acrylic coating as identified in the manufacturer’s specification.

• Application shall only be done in the time available so that all applied material has sufficient time to dry to the touch (tack free time) before any rain or ambient moisture contacts the surface.

• Application should be completed when air and material temperatures are between 40

°F and 120 °F.

• Application shall be in accordance with manufacturer’s specification, by roller, brush, or spray.

• A uniform coat shall be applied over entire surface, avoiding excessive rolling, and/or brushing.

• Application at penetrations should be done as to not leave any voids or bubbles.

• Application of coating shall follow manufacturer’s specification and be applied in sufficient thickness and quantity to meet the material specifications and Manufacturer’s warranty.

3.4 Storage and Disposal

All materials used for cleaning, priming, and coating the roof shall be stored in accordance with the manufacturer’s specification. All debris generated, empty or used containers, application tools, etc. shall be disposed of by the Contractor in accordance with manufacturer’s recommendation and applicable standards.
