Leave all such work undamaged. Clean, repair or replace, and repaint, damaged work as directed by Architect.

B. Remove temporary protective wrappings, provided by others for protection of their work, after completion of painting operations. Upon completion of work, clean all window glass and other paint spattered surfaces. Remove spattered paint by proper methods of washing and scraping. Use care not to damage finished surfaces.

C. Remove any surplus materials, scaffolding and debris, leave areas broom clean.

3.9 WASTE MANAGEMENT

A. Do not use kerosene or any such organic solvents to clean up water based paints. Properly dispose of paints or solvents in designated containers. Close and seal partially used containers of paint to maintain quality as necessary for reuse. Store in protected, well - ventilated, fire - safe area at moderate temperature. Place materials defined as hazardous or toxic waste in designated containers.

3.10 COLOR SCHEDULE

A. Apply paint in colors, textures, and patterns of wall coating systems as selected by the Owner’s

Representative. Colors of finish coats shall match existing adjacent surfaces or as selected by the

Owner’s Representative. Manufacturers' names and color identification are used for the purpose of color identification only.
