There are many good reasons to have your sliding glass doors tinted. Tinting your doors offers privacy, you can allow the heat of the sun to enter your home but reduce the glare, and tinting material can also help to reinforce your window and prevent small pieces from flying if the window should be shattered. You can tint your own sliding glass door and save money on the labor costs you'd have to pay to have a professional do the job.
Purchase enough window tinting material to cover your sliding glass doors. To ensure you purchase enough, measure the exposed window surface area of your doors and then purchase 10 percent more material in case you make any mistakes during installation. You can purchase window tinting film from your local home-improvement store, and there is usually a wide variety of tinting film to choose from.
Measure and cut your window tinting film with scissors so that it will fit exactly on to your sliding glass doors. Measure your windows no less than three times, and even then you should place the tinting film up against the window just to make sure the measurements are correct. Use a metal straight edge as a guide to make straight cuts.
Wipe down your sliding glass doors with a wet towel to clean any of the larger debris off of the window.
Liberally spray ammonia-based window cleaner on your doors, and then thoroughly dry them with a towel. Do not proceed to the next step until your sliding glass doors are completely dry.
Install the window tinting material onto your sliding glass doors. Use a small tinting material roller to help work out the air pockets and bumps that develop under the tinting material.
Use the metal straight edge to smooth the tinting material out completely, and make it clear against the glass.
