Having glass mosaic tile installed in your home is a wonderful addition. It not only makes the space beautiful but it also increases the value of your home. The tile must be installed and grouted properly though. If the wrong color grout is used, your project will turn out horrible. Sometimes picking the right grout color can be very difficult especially if you have a lot of different colors in the same installation. Here are a couple of scenarios.
Let's say that you put up white glass mosaic tile in your bathroom. Then you decide to put black tile on the floor. When it comes to time to grout, you may have some trouble deciding on a color. If you choose a light grout for the white tiles then the black will look very broken. However if you choose a dark grout for the black tiles, the whites will look broken.
Now let's say that you are going to create a cool mosaic stripe look. You will run stripes of three colors down the wall; red, white, and dark gray. Once again, you have a grout color problem. If you choose a dark gray grout then the white will be severely broken up. Too light and the gray will look horrible.
So what do you do? Two tone grouting is the answer. Simply grout each section separately. You will need that blue painters tape and lots of newspaper or craft paper. It is recommended to grout with the dark grout first so it can not stain the lighter grout. Carefully tape off the sections that are being grouted first. Make sure you have a clean line of tape so your grout joint is straight. Now completely cover the section that you do not want to grout with the newspaper. Take no chances as grouting can be very messy.
Grout all the sections that need the dark grout and wipe it down completely. Make sure to pull the tape off within 10 minutes. Totally clean up all the dark grout so you do not accidently get it mixed in with the lighter grout. Wait until the dark grout has set up. Now repeat the steps with the light grout.
You are finished and have great looking grout joints that no one will see because they should be focused on your tile work instead!
