Having a frosted glass block shower increases the privacy and instead of hiring a professional doing the job you can do it by yourself very easily. The glass blocks can be frosted also for enhancing its visual appeal and you can give a unique look by frosting it on your own. For frosting the glass blocks, sandblasting the glass is the most common option but you can also frost the glass block by using acid etch, frosted glass films, or use frost window paints. By doing this on your own you can save a lot of money and add your own custom touches.
Step 1: Preparation
At first you need to decide the method that you are going to use for frosting the glass block shower. After deciding this, buy the required material that is needed for frosting from any home improvement store. All the products required for frosting are easily available and you do not need to search hard for it.
Next lay down long and wide pieces of newspaper or any old piece of fabric in a place that is away from household object or other vital things. Make sure to lay the newspaper on a hard surface. Before you start frosting the glass blocks make sure they are clean and dry. For protecting the glass blocks from any kind of unwanted damage you can apply tape around the edges of the glass block.
Step 2: Frosted Spray Paint
Make sure you have taken adequate protection for yourself before you start frosting the glass blocks by frost paint. Always paint the outer side of the glass block so that the paint does not get damaged soon due to continuous exposure to water and moisture on the inner side. Apply a thin layer of paint on the glass blocks by keeping then on the laid newspaper and using the spray bottle. Make sure the layer is even and you are not applying too much paint on some particular spot. Allow the blocks to dry for 24 hour before installing them back.
Step 3: Etching Acid
If you plan to frost the glass blocks by etching acid make sure you take the necessary precautions. Keep children and pets away from the place where you are going to frost it using the etching acid. The benefit of using etching acid is that you can make patterns and frost a part of the glass block for creating a design.
You need to use stencils for doing so. Apply the cream over the stencil and make sure the stencil is not moving on the surface of the glass. Allow the cream to remain on the glass surface for the amount of time specified by the manufacturer. Once the time is over, remove the cream by rinsing the glass block with water. While doing this make sure you take proper hand protection. After removing the cream dry the glass blocks in air and then install them back.
