A frosted glass window allows for privacy while still letting light in. They are commonly found in household bathrooms, but can also be seen in front door window panels. Making a frosted glass window is a relatively easy project.
Step 1: Cover the Surroundings
Frosted glass spray paint is usually applied to the interior of the window glass. This is so the paint is not exposed to outside elements such as rain, wind, etc. If the window you are painting has not been installed yet, taping can be drastically reduced. Spray it in an area where no overspray will drift onto other objects. If you are painting an existing window, you will need to cover the surroundings. Cover the interior walls and trim to protect from overspray. Use masking paper or plastic sheeting. Cut it with scissors and tape it using the painter's tape. Avoid any openings or gaps that may allow overspray to enter. If your window has latticework or mutton bars (strips of wood between the glass), you will need to cover it with tape.
Step 2: Use Caution
Spray-paint fumes are notoriously pungent and can be hazardous to your health. Make sure the area in which you will be spraying is well ventilated. You should also use a certified breathing mask and safety glasses when spray painting, as well as protective gloves. If the fumes become too strong because of an ill-fitted mask or a lack of ventillation, leave that area immediately to avoid the harmful airborn emissions.
Step 3: Time to Frost
With the surrounding areas protected from overspray by the masking paper or plastic sheeting, it's time to paint. Read the label on the back of the frosted-glass spray paint can. You will most likely need to shake the can for a certain length of time (usually 1 to 2 minutes) to mix the contents well. As you shake the can, you should hear the ball in the paint can rattle. Test the can by spraying it on a small piece of cardboard. If the can is spraying correctly, begin spraying the window's glass. The directions on the can will most likely advise using several small spray coats. This ensures the glass is uniformly coated without running the risk of paint runs. Adhere to the can's directions on the wait time required between coats.
Step 4: Cleaning Up
With all of the painting complete, use a clean cloth and the mineral spirits or paint thinner to clean the spray can and any overspray from your hands. Wash with soap and warm water afterward.
Step 5: Remove the Masking
Once the paint is completely dry, remove the masking paper or plastic sheeting. Go slowly when removing the tape, so as not to peel any paint from walls or other areas. Overspray may have stuck to unwanted places. It should be removed with caution. Mineral spirits can damage some finishes. Using mineral spirits on painted surfaces such as walls could damage the paint.
With your window now frosted, you can benefit from outside light while keeping the room private.
