PART 3 EXECUTION

3.1 EXAMINATION

A. If preparation of glass surfaces is the responsibility of another installer, notify Specifier in writing of deviations from manufacturer’s recommended installation tolerances and conditions.

1. Glass surfaces receiving new film should first be examined to verify that they are free from defects and imperfections, which will affect the final appearance:

B. Do not proceed with installation until glass surfaces have been properly prepared and deviations from manufacturer’s recommended tolerances are corrected. Prepare surfaces using the methods recommended by the manufacturer for achieving the best result under the project conditions.

C. Commencement of installation constitutes acceptance of conditions.

3.2 PREPARATION

A. Clean surfaces thoroughly prior to installation.

B. Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.

C. Refer to Manufacturer’s installation instructions for methods of preparation of film attachment systems.

3.3 INSTALLATION

A. Install in accordance with manufacturer’s instructions.

B. Cut film edges neatly and square at a uniform distance of 1/8 inch (3 mm) to 1/16 inch (1.5 mm) of window sealant. Use new blade tips after 3 to 4 cuts.

C. Spray the slip solution, composed of 1 capful of baby shampoo or dishwashing liquid to 1 gallon of water, on window glass and adhesive to facilitate positioning of film.

D. Apply film to glass and lightly spray film with slip solution.

E. Squeegee from top to bottom of window, using a security film squeegee no wider than 5 inches. Apply firm pressure with squeegee to maximize effectiveness of slip solution removal. Spray slip solution to film as needed to reduce squeegee friction.

F. Bump film edges with a lint-free towel wrapped around edge of a 5-way tool.

G. Upon completion of film application, allow 30 days for moisture from film installation to dry thoroughly, and to allow film to dry flat with no moisture dimples when viewed under normal viewing conditions.

3.4 CLEANING AND PROTECTION

A. Remove left over material and debris from Work area. Use necessary means to protect film before, during, and after installation.

B. Touch-up, repair or replace damaged products before Substantial Completion.

C. After application of film, wash film using common window cleaning solutions, including ammonia solutions, 30 days after application. Do not use abrasive cleaners or brushes to avoid scratching film. Use only synthetic sponges or soft cloths.
