3 Graveled Built-up Roofing System Restoration The Tremco Cold Applied Restoration Process is a preventive maintenance system which consists of repair materials specially designed to correct defects. The restoration process includes the addition of upgraded high performance flashing components and restorative top pours to rejuvenate the weathering layer of bitumen. It is designed to extend the life of a functioning built-up roof. It is not a substitute for replacement, which is necessary when deterioration of the roof system or the deck is so extensive that it cannot be remedied by localized repair. Basic Use: The Tremco Cold Applied Restoration Process is used to recondition an existing serviceable roof to extend its service life without the cost and trouble of complete roof membrane replacement. Applicable Standards: Consult your Tremco representative regarding current UL Classifications, FM Approvals and details on applicable standards and fire ratings. System Composition: The physical properties of the Tremco restoration system may be customized to your specific requirements by the addition and/or deletion of approved components. Before any decision is made to restore an existing roof, contact your Tremco representative to obtain a complete roof analysis, including a Thermocore SM roof moisture survey and a TRACE roof analysis. Based on this information, your Tremco representative will make the appropriate recommendation for your roof. Contact your Tremco representative for specific system configurations to meet your requirements. The Tremco Cold Applied Restoration Process consists of the following steps, repairs and procedures. Inspection Procedure: 1) Visually inspect the complete roof to obtain a thorough understanding of the original roof construction and to identify the obvious roof defects such as: Exposed felts Blisters Ridges Splits Damaged flashing Standing water (over) 4.5-1

4 2) Conduct a Thermocore roof moisture survey of the insulated roof area to identify areas of wet insulation. 3) Verify roof construction and condition through a TRACE roof analysis. 4) Prepare a condition report containing the results of the visual inspection, the thermographic survey and the core analysis, which then forms the basis of the maintenance recommendations. Preparation Procedure: Proper preparation of the roof surface is critical to the success of the restoration process: Remove loose gravel, dirt and debris. Expose and prepare flashing areas requiring repair or rebuilding. Repair or remove and replace deteriorated membrane, insulation and deck. Clean entire roof surface. Restoration Procedure: 1) Restore the flashings at all roof perimeters, projections, expansion joints and around roof top equipment by repairing, reconstructing or replacing defective flashings. 2) After the preparation work has been carefully completed, a Tremco restorative top pour is applied over the entire membrane surface. Besides filling the cracks in the existing top pour, the Tremco restorative top pour is designed to penetrate and adhere to areas of exposed and weathered felts. The Tremco restorative top pour adheres tenaciously to the existing brittle, aged bitumen top pour, reestablishing waterproofing continuity. 3) New metal counterflashing may be installed (or the original, undamaged metal counterflashing may be re-installed) to provide additional protection for the restored flashings. 4) The Restoration Process is completed by the application of gravel as a barrier against ultraviolet light and its photo-oxidizing effects.

Packaging: Wall-Tite and Wall-Tite F are available in 19 L (5 gal) containers and 200 L (53 gal) plastic-lined barrels. Precautions: User must read container labels and Material Safety Data Sheets for health and safety precautions prior to use. General Installation Information: 1) Prior to application, existing hairline cracks (less than 1.5 mm [.0625 in]) should be filled by brushing or spraying Wall-Tite into each crack in sufficient quantity to totally conceal the crack. 2) All cracks larger than a hairline should be considered as moving cracks and should be routed, cleaned, and filled with TremSEAL HP. To achieve a smoother final surface on block, apply a high quality acrylic block filler at 1.2 to 1.8 m 2 /L (50 to 75 ft 2 /gal) or according to recommended coverage rates on labels. 3) Specific masonry wall types should follow these guidelines in preparing walls for application. Unpainted Walls: Bare concrete, brick, stucco, or masonry must be structurally sound, clean, dry, fully cured, and free from dust, curing agents, or release agents, efflorescence, scale and other foreign materials. Prime the substrate with Wall-Tite Primer. Previously Painted: All dust, dirt, efflorescence and loosely adhered old paint or coating must be removed. Paints that show failure due to alkalinity and moisture recognizable by flaking, peeling, and white deposits must be completely removed. Wash chalky surfaces with a clean rinsing detergent. Rinse walls thoroughly with clean, fresh water. Allow the surface to fully dry. Perform spot adhesion tests. If tests indicate poor or marginal adhesion, retest by first applying Wall-Tite Primer, then Wall-Tite. If adhesion is still marginal or poor, remove existing paint or coating by sandblasting or other mechanical means. 4) Mix Wall-Tite thoroughly before use with a slow-speed mixer. Keep material mixed. If left standing, Wall-Tite will settle into a two-stage suspension. 5) Wall-Tite may be applied by either conventional or airless spray equipment. Airless spray is the most effective method for obtaining uniform film build. Brush or a roller may be used for touch-up and edging work or for small areas not practical for spray application. 6) All surfaces should be sprayed with multidirectional spray passes to ensure positive coverage. Wall-Tite must be applied in a minimum of two separate coats to ensure a uniform film build and proper cure rate. Allow first coat to cure touch-dry. Apply second coat perpendicular to first coat.
