Frosted Glass Guide: How to Frost Glass in 5 Steps

Frosted glass is any glass that has been made to be opaque and is not transparent. This effect is often used for privacy in bathroom windows, shower doors, and other glass doors without sacrificing the natural light that a window lets in. Industrial frosted glass is often made from sandblasting or etching it with acid. You can frost glass at home using a number of permanent or temporary DIY methods, from spray paint to window adhesives.

There are a few types of industrially-frosted glass available if you’re looking to purchase it to install in your home.

1. 1. Acid-etched glass: Acid-etched glass is made by etching the surface of transparent glass with acid, giving it a heavily blurred surface that still allows light in. Acid-etched glass has a smooth, uniform texture, unlike sandblasted glass.
2. 2. Sandblasted glass: Sandblasted glass is made by spraying sand over the surface of the glass to lightly damage and obscure its transparent surface. Sandblasted glass is rougher than acid-etched glass and is slightly less uniform in its frosted appearance.
3. 3. Satin glass: Satin glass is either acid-etched or sandblasted to form a surface that is more transparent than the other two methods. Looking through satin glass will slightly blur any figures on the other side, rather than completely obscure them.

Here are some do-it-yourself methods for frosting your own glass at home.

1. 1. Removable window adhesive: The simplest way to frost your own glass is to use frosted contact paper that sticks directly to your glass surface. If you ever want your transparent glass back, simply peel off the frosted window film.
2. 2. Frosted glass spray paint: Any home improvement store sells a number of frosted glass spray paints. Lightly spray the paint onto the clear glass, using painter's tape and drop sheets to protect any surfaces from overspray. Layering a few light coats of frosted spray will allow you to control the opacity.
3. 3. Etching cream: Etching cream is an effective way to permanently frost your glass. Home-etching is best for smaller surfaces or when making frosted patterns in glass. Make sure to test a small patch of glass before working on larger areas. Always wear gloves when working with etching cream because it should never make contact with your skin.

Whether you’re using spray paint, etching cream, or removable window adhesive, follow these five simple steps to frost your own glass at home.

1. 1. Clean your glass surface. Using a window cleaner and paper towel or squeegee, clean the glass that you plan to frost. Rub it dry with a cloth.
2. 2. Stencil a pattern, if you like. If you're frosting a small section of glass or making a pattern on your glass, cut and lay out a stencil of your pattern or design. Make a stencil out of painter's tape, use stickers, or use tape to stick paper stencils to your glass.
3. 3. Cover the surrounding areas. Cover any surrounding surfaces in the area that you don't want to frost with drop sheets or plastic bags.
4. 4. Wear protective gear. Make sure to wear protective gear especially if you’re working with spray paint or etching cream. Etching cream can be bad for your skin, so make sure to wear protective gloves. Wear goggles if you’re working with spray paint to prevent it from getting in your eyes.
5. 5. Frost your glass. You are now ready to frost your glass panels using your preferred method. Using frosted adhesive sheets is straightforward; simply cut a section of adhesive to fit the size of your window, and lay it on your surface slowly to avoid air bubbles. Using etching cream or spray paint can be more complicated so follow the instructions that come with the product carefully.
