For maximum performance of a coating, the surface must be adequately prepared to provide long lasting adhesion of the coating to the substrate, thereby reducing the cost of maintenance repainting. The number one cause of paint system failure is improper or insufficient surface preparation.  \nThis section covers the proper and most effective surface preparation methods. The recommended surface prep will vary depending on the substrate, the condition of the substrate and/or existing coatings, and the material to be applied. The selection of tools and surface preparation methods are the responsibility of the painting contractor.  \nPrior to any surface preparation, correct all construction defects such as spalled bricks, rotting wood, or rusting steel which may cause or contribute to paint failure. The most common cause of exterior paint failure is moisture intrusion. Leaking gutters, missing caulk, improperly installed flashing, roof leaks and open or uncapped parapets are just a few of the construction defects which will allow water to attack the paint film. These defects should be addressed prior to surface preparation and selection of finishing systems.  \nVarying conditions and coating requirements may alter the methods of surface preparation listed in this section. Upon request, Farrell Calhoun will send a technical representative to visit a project for the purpose of generating a surface preparation and painting specification. Farrell-Calhoun cannot be held responsible for improper or inadequate surface preparation.  \n1 | P a g e SURFACE PREPARATION  \nALUMINUM  \nGENERAL:  \nAluminum and aluminum alloys are widely used as materials of construction for store fronts, windows, doors, boats and aircraft. Aluminum products have an advantage over ferrous metals in that they are light in weight and do not rust or corrode when exposed to the air. Under normal exposure, aluminum produces aluminum oxide which forms a tight film and aids in preventing further oxidation.  \nAluminum will rapidly corrode and pit when exposed to acids, alkalis, or their fumes. When aluminum is used under these exposures, it must be protected with the proper coating.  \nSURFACE PREPARATION: NEW Aluminum  \nRemove fabricating oil and lubricants by solvent cleaning with per SSPC-SP1 . Weathering for a month to 2 months should remove these contaminants, but since this method is uncontrollable, FarrellCalhoun recommends non-Hydrocarbon solvent cleaning prior to painting.  \nPrime with a 100% acrylic primer such as Farrell-Calhoun \\#697 100% Acrylic Bonding Primer or FarrellCalhoun \\#5-56 All Purpose Metal Primer.  \nSURFACE PREPARATION: PREVIOUSLY PAINTED Aluminum / Aluminum Siding /Anodized Aluminum  \nRemove all loose paint, dirt, and other surface contaminants by power washing, scraping, or sanding. Aluminum is a soft metal; caution should be taken when preparing the surface so as not to damage the aluminum. When power washing aluminum siding, never spray in an upward direction forcing water behind the siding. Remove mildew with a bleach solution (refer to Mildew Removal on page 17 of this section) . Feather all rough and irregular paint edges as not to show through subsequent coatings. Anodized aluminum should be scuff sanded to provide tooth for paint application.  \nPrime with a 100% acrylic primer such as Farrell-Calhoun \\#697 100% Acrylic Bonding Primer or FarrellCalhoun \\#5-56 All Purpose Metal Primer.  \nPriming is not required when using Farrell-Calhoun exterior 100% Acrylic products such as \\#200, \\#2200 or \\#2400 due to their excellent adhesion properties. It is always appropriate to check adhesion on all substrates before proceeding with the entire job.  \n2 | P a g e SURFACE PREPARATION  \nCONCRETE and MASONRY  \nGENERAL:  \nConcrete is made up of three basic components: water, aggregate (rock, sand, or gravel) and Portland cement.
