          PART 3EXECUTION
 
          3.1EXAMINATION
 
          A.Do not begin installation until substrates have been properly prepared.
          1.If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.
 
          B.Coordination of Work: Review other Sections in which primers are provided to ensure compatibility of the total system for various substrates. On request, furnish information on characteristics of finish materials to ensure use of compatible primers.
          1.Notify Architect of anticipated problems when using the materials specified over substrates primed by others.
          ** NOTE TO SPECIFIER ** Coordinate primers specified in other Sections with undercoats and finish coats specified in this Section to ensure compatibility of materials. Some masonry coating coatings will lift incompatible primers or have poor adhesion when applied over incompatible primers. Delete if not required.
          2.If a potential incompatibility of primers applied by others exists, obtain the following from the primer Applicator before proceeding:
          a.Confirmation of primer's suitability for expected service conditions.
          b.Confirmation of primer's ability to be top coated with materials specified.
 
          3.2PREPARATION
 
          A.General: Remove items already installed that are not to be coated. If removal is impractical or impossible because of size or weight of the item, provide surface-applied protection before surface preparation and coating.
          1.After completing coating operations in each space or area, reinstall items removed using workers skilled in the trades involved.
 
          B.Cleaning: Before applying coat or other surface treatments, clean substrates of substances that could impair bond of the various coatings. Remove oil and grease before cleaning.
          1.Schedule cleaning and coating so dust and other contaminants from the cleaning process will not foul surrounding area and surfaces.
 
          C.Surface Preparation: Clean and prepare surfaces to be coated according to manufacturer's written instructions for each particular substrate condition and as specified.
          1.Clean all surfaces of dirt, grease, form oil and wax. Remove loose or chalky deposits, parting membranes and efflorescence. Point cracks, voids and surface fissures.
          2.Point holes, cracks, fissures, wall-floor joints, cold joints and non-working joints with patching compound specified. Install per manufacturer instructions.
          ** NOTE TO SPECIFIER ** Coordination of previously applied prime coats with masonry coating coatings is critical. If compatibility problems exist, it may be necessary to remove the primer. Delete provision not required.
          3.Remove incompatible primers.
          ** NOTE TO SPECIFIER ** Delete subparagraph and associated subparagraphs below if cementitious surfaces are not to be coated, or revise to suit Project.
 
          D.Cementitious Substrates: Prepare concrete, brick, concrete masonry block, and cement plaster surfaces (stucco) to be coated. Remove efflorescence, chalk, dust, dirt, grease, oils, and release agents. Roughen as required to remove glaze. If hardeners or sealers have been used to improve curing, use mechanical methods to prepare surfaces.
          1.Use abrasive blast-cleaning methods if recommended by coating manufacturer.
          2.Determine alkalinity and moisture content of surfaces by performing appropriate tests. If surfaces are sufficiently alkaline to cause the finish coat to blister and burn, correct this condition before application.
          3.Do not coat surfaces if moisture content exceeds that permitted in manufacturer's written instructions.
 
          E.Material Preparation: Carefully mix and prepare coating materials according to manufacturer's written instructions.
          1.Maintain containers used in mixing and applying coatings in a clean condition, free of foreign materials and residue.
          2.Stir materials before applying to produce a mixture of uniform density. Stir as required during application. Do not stir surface film into the material. Remove film and, if necessary, strain coating material before using.
          3.Use only the type of thinners approved by manufacturer and only within recommended limits.
          ** NOTE TO SPECIFIER ** If tinting is not required, delete below. Different tints will show through as topcoat erodes.
 
          F.Tinting: Tint each undercoat a lighter shade to simplify identification of each coat when multiple coats of same material are applied. Tint undercoats to match the color of the finish coat, but provide sufficient differences in shade of undercoats to distinguish each separate coat.
 
          3.3APPLICATION
 
          A.General: Apply masonry coatings according to manufacturer's written instructions.
          1.Use applicators and techniques best suited for the material being applied.
          2.Do not apply masonry coatings over dirt, rust, scale, grease, moisture, scuffed surfaces, or conditions detrimental to forming a durable coating film.
          3.Provide finish coats compatible with primers used.
          4.Extend coatings into floor and wall joints and other areas, as required, to maintain system integrity and provide desired protection.
 
          B.Application Procedures: Apply coatings by brush, roller, spray, or other applicators according to manufacturer's written instructions.
          1.Apply number of coats at coverage rate recommended by manufacturer unless otherwise noted.
 
          C.Completed Work: Match approved Samples for color, texture, and coverage. Remove, refinish, or recoat work that does not comply with specified requirements.
 
          3.4CLEANING
 
          A.After completing coating, clean glass and coating-spattered surfaces. Remove spattered coating by washing and scraping without scratching or damaging adjacent finished surfaces.
 
          3.5PROTECTION
 
          A.Protect work of other trades, whether being coated or not, against damage from coating. Correct damage by cleaning, repairing or replacing, and recoating, as approved by Architect.
 
          B.Provide "Wet Coat" signs to protect newly coated finishes. After completing coating operations, remove temporary protective wrappings provided by others to protect their work.
 
          C.After work of other trades is complete, touch up and restore damaged or defaced coated surfaces.
