Remove all dirt and all surface contaminants that will interfere with adhesive of subsequent coats without damaging the substrates or adjacent areas
 

Wire brush all loose and peeling paint and dust all surfaces before spot priming or applying finish coats.
 

Power washes all areas to be painted, and use a mild detergent solution such as MI-T-M's surface prep if required. Then rinse with clear   clean water until all residues has been removed from all surfaces. Allow the surfaces to thoroughly dry before proceeding with preparation or painting.
 

Moisture content for Masonry and Stucco must not exceed 17%.
 

After washing the surfaces, the areas must be carefully examined for cracking, blistering, peeling or flaking of existing paint. All loose, unsound, or non-adhering paint must be removed.
 

Efflorescence, white residue salt deposits, should be removed by wire brushing and acid etching with phosphoric acid. Rinse all surfaces with clean, clear water to remove any remaining residue.
 

Note : Efflorescence, which appears on cementations or plaster surfaces, is caused by moisture entering or contained in the substrate. Water-soluble salts in the masonry are brought to the surface where the water evaporates, leaving white residue salt deposits. Defects, which cause this problem, must be corrected before any painting is attempted.
 

Where rust stains are present the source must be identified and corrected (i.e. nail heads, flashing, handrails, etc.). Surfaces should then be cleaned and spot primed with the appropriate primer or sealer as stated in the Finish Schedule.
 

Large cracks must be V-grooved out and all other surface defects, such as holes and the like, must be repaired using the appropriate patching materials to match the surrounding surface profile. Dust surface and spot prime all patched areas with the appropriate primer or finish coat as stated in the Finish Schedule.
 

Degloss all glossy and previously enameled surfaces to provide a roughened surface or “Tooth” for good adhesion of subsequent coats.
