Why cant you use regular paint for painting on glass?

Glass is a very simple substrate, yet glass has very unusual scientific properties. Glass attracts atmospheric moisture inherently, has tricky expansion and contraction properties, and is non-porous making it extremely difficult to bond to. Glassprimer™ self priming technology actively modifies the glass surface molecular structure properties to resist atmospheric moisture and creates molecular chain cross links that are compatible for Glassprimer™ GPWB128 waterbased (waterborne) glass paint to permanently bond to. Glassprimer™ GPWB128 waterbased (waterborne) glass paint is industrial strength, chemical resistant, scratch resistant, water resistant, and permanently bonds to glass. Glassprimer™ GPWB128 is truly a revolutionary product.

What thickness/type of glass is generally used for back painted glass?

The industry standard glass type and thickness for back painted glass back splashes, cabinet coverings and wall coverings is 1/4″ starphire glass (low iron glass). This glass is optically clear with no green effect like regular glass. Since this glass is clear, it will not modify and dull the back painted color. In some cases, regular glass (slightly tinted green) is used for back painted glass to achieve a particular color, especially when back painted white (regular glass painted white creates a light aqua green effect). Back painted glass is generally not tempered unless you want it to be. If you have an area behind a stove of cook top that will have back painted glass, it may require tempered glass to hold up to the temperature fluctuations that may crack a non tempered piece of glass. Glassprimer™ GPWB128 glass paint can be applied to any glass surface, any thickness, and any size glass such as: annealed glass, tempered glass, low iron glass, starphire glass, slumped glass, casted glass, reeded glass, spandrel glass, and more…

What thickness glass is used for back painted glass counter tops and table tops?

Half inch (1/2″), three quarter inch (3/4″), and one inch (1″) glass is generally used for back painted glass counter tops and back painted glass table tops. Non tempered glass is generally used.

How do you apply Glassprimer™ GPWB128 waterbased (waterborne) glass paint?

Glassprimer™ GPWB128 waterbased (waterborne) glass paint can be applied to glass easily with any paint spraying equipment, a paint roller, or a paint brush.

What is the best way to clean glass before painting glass?

Cleaning glass properly is the most important step when back painting glass. Scrub glass with isopropyl rubbing alcohol and #000 steel wool. Now clean the glass surface again with new paper towels and isopropyl rubbing alcohol. Make sure the glass surface is squeaky clean feeling and sounding. *Note: Acetone can also be used to clean glass that might have adhesive residue from glass bumpers, heavy oils or dirt. Degreaser, water and #000 steel whool can also be used for pieces of glass that are really dirty/large. Always be sure to follow up with cleaning glass with isopropyl rubbing alcohol and clean paper towels 2 or more times before painting glass.

How do I remove Glass Paint overspray on glass?

If you get over spray on the glaze side or edges of your glass there is no need to worry. Cleaning the over spray off the glass is as simple as taking#000 steel wool and polishing off the over spray once it is dry. To get ride of thick areas of paint, use single edge razor blades and follow with #000 steel wool.

How do I remove imperfections in backpainted glass?

Sometimes glass is not completely cleaned, small insects, or debris in the air can get on the glass surface while you are back painting the glass. The best solution to removing these types of imperfections is to wait until the paint has cured. Once it has cured it is best to take 120 grit sand paper and gently sand through the paint where the imperfections exist. (don’t worry if the glass surface gets a little obscured by the sand paper) Once the imperfection is removed, clean the bare glass area with rubbing alcohol and clean paper towels. Now you can re-paint those areas with a spray gun, brush or finger paint. (paint color tone might seem lighted when the paint is wet. Once dry, the color will usually blend perfectly)

How do I clean Glass Paint from my paint gun and tools?

We recommend water, a cloth and small brushes to clean out your paint gun canister. Spray water through the paint gun for 30-60 seconds after the gun is clean. Repeat several times if necessary. Sometimes it is good to disassemble the paint gun and clean all of the internal parts with water, and/or let stand in a cup of water for several hours.

How do I install finished GPWB128 backpainted glass?

Neutral cure silicone glue and/or double sided glazers tape can be used to install waterbased GPWB128 back painted glass. Most GE Silicone II series silicone glues are neutral cure. Even though acetoxy cure silicone glues have had no negative effect on Glassprimer™ back painted glass in adhesive compatibility testing, we still do not recommend the use of acetoxy cure silicone glues. Mirro mastic has been used by users of GPWB128 with no negative results, but Mirror mastic has not been scientifically tested for use with GPWB128.

What is “neutral cure silicone glue” ?

Neutral (meaning neutral alcoxy) silicone sealants release alcohol as they cure, and has almost no smell. This type of silicone glue is also referred to as “acid free silicone glue”. This is recommended for use with back painted glass.

What is “acetoxy cure silicone glue” ?

Acetoxy silicone sealants release acetic acid (which smells a little like vinegar) as they cure. Acetoxy silicones can discolor the silvering on mirror. This is not recommended for use with back painted glass or mirror.
