5 Mistakes to Avoid when Using Glass Spray Paint

Glass spray paint can bring to life old household glass items, windows, or mirrors. It is a very inexpensive way to spruce up home décor on a budget, if done correctly. By being aware of these simple mistakes, they can be avoided so you can produce a beautifully done project to be proud of.

Not Reading All the Directions First

Before you start your project, make sure you read all the directions on the back of the can. This can include safety tips, recoat times, preparing your surface. Some glass spray paint calls for you to use a primer on the surface of your glass. Others require you to use sandpaper on your glass to make a better surface for the paint to adhere to. It is very important to be prepared by reading the directions.

Not Working in a Well Ventilated Room

Working outside is always the best, but sometimes that is not possible. When you must work indoors, make sure you work in a room that is well ventilated. Open a window or door. If that is not feasible, turn a fan on to circulate air. Don’t point it directly onto your project or where you are spraying the paint. It is also a good idea to wear a face mask and safety goggles to keep mists of spray paint out of your lungs, mouth, and eyes.

Over or Under Spraying Your Project

A common mistake that is made is not using the proper technique while spraying which causes over and under spraying. Over spraying will cause an uneven surface by either leaving dried drip marks or by the paint building up in one spot. Under spraying will also cause an uneven surface. Unpainted spots in what you are working on will have to gone over with the paint. As your spraying the unpainted spot, the other parts that you hit with spray will be getting a second coat. The best way to spray is to make sweeping, even movements.

Not Starting with a Dry, Clean Surface

Spray painting on a dirty surface will cause the paint to peel and chip off. Paint will stick to the dirt and grime instead of the surface of your glass item. Make sure the surface of your project is cleaned thoroughly with soapy water and allowed plenty of time to dry completely. Some household cleaners or detergents can be used to clean your glass, but make sure it does not leave an oily or filmy residue behind.

Applying One Thick Coat

When you try to apply one thick coat, over and under spray are very likely to occur. Instead paint your glass with several thin coats. Press down the nozzle and use a long sweeping motion to the end of your glass. Release the nozzle and start another long sweeping motion. Overlap the paint by no more than one third of an inch. Each manufacturer of glass paint has a timeframe on when to recoat. Read the directions on the back of the can and apply another thin coat accordingly.
