Scope of Work: Exterior
All mildew is to be treated and killed prior to pressure washing. Apply a solution composed of 50% Chlorine bleach and 50% water, allow standing 25 minutes, then thoroughly rinsing. Exterior surfaces to be painted are to be pressure cleaned with a minimum of 3000 p.s.i., to properly prepare the surface. Peeling areas may require the use of a rotating tip. Remove all loose paint, dirt grease, oil, or other foreign matter which would adversely affect adhesion of coatings to be applied. Any galvanized metal surface, such as drip caps, gutters, downspouts, vents, etc. will be wiped down with a solvent to remove any surface grease or oils.
Occasionally the Contractor's method of cleaning develops or reveals an unforeseen condition, which may require additional labor and materials. The Contractor must make the owner/agent aware of these conditions as they appear. Examples of unforeseen conditions are wood delaminating, rotten wood, concrete restoration, and deteriorated metal surfaces.
Clean all metal surfaces using a wire brush or power tool to remove all traces of rust scale. Sanding may be needed before priming, in order to achieve a smooth finish. Metal that is rusted and pitted will be treated with Ospho rust inhibitor or equal. This is for use on iron, steel aluminum, and galvanized metals. Any areas where spalling (masonry broken by the swelling of rusting metal) is evident are to be treated by removing any loose stucco, and chipping out any loose stucco to expose the rusting metal surfaces. The rusting metal must then be wire brushed, mechanically or manually, until a sound substrate is attained. All bare metal will be primed with an approved metal primer prior to finish painting.
Crack Treatment (stucco only)
All cracks will be sounded out to determine if hollow areas or delaminating of the stucco is present. Where hollow spots are found, all loose substrate is to be removed, affected area primed with concrete primer/ bonding agent, and repaired using a vinyl concrete patcher to match surrounding areas. Cracks less than 1/16" will be cleaned, primed with a high-grade sealer/bonder, and patched using an elastomeric patching compound. Cracks greater than 1/16" a "stairway" block cracks will be V'd out or mechanically sawed out, cleaned, and primed. A fibrous patching compound will then be applied completely filling void and feathered out overlapping the area. Two coats of patch are required for cracks greater than 1/16".
Exterior wood surfaces are to be pressure cleaned as to remove dirt, mildew, and any loose paint. Scraping of loose dry paint may sometimes be necessary, followed by sanding to make smooth. Bare exposed wood will be primed with an exterior oil based primer prior to finish coating.
Caulking of Surfaces
All fascia joints, doorjambs, windows, sliding glass doors, and garage doorjambs are to be caulked with a 30 year siliconized painter's caulk prior to finish coating.
Sealing of Stucco Surfaces
All stucco surfaces prior to the finish coat are to be sprayed with a high-grade latex masonry sealer bonder.
Spray and back roll method (Definition)
