    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 for Impact Protection Adhesive or Impact Protection Profile film attachment systems.
    3.3 INSTALLATION

    1. Install in accordance with manufacturer’s instructions.
    2. 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.
    3. Spray the slip solution, composed of one capful of baby shampoo or dishwashing liquid to 1 gallon of water, on window glass and adhesive to facilitate proper positioning of film.
    4. Apply film to glass and lightly spray film with slip solution.
    5. Squeegee from top to bottom of window. Spray slip solution to film and squeegee a second time.
    6. Bump film edge with lint-free towel wrapped around edge of a 5-way tool.
    7. 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.
    8. If completing an exterior application, check with the manufacturer as to whether edge sealing is required.
    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.
