Randy Evans emailed me a photo of his stone mosaic backsplash and asked for advice in choosing a grout color.
Even though this project isn’t figurative mosaic, and the grout gaps have the width of masonry joints (much larger than the gaps recommended for small glass mosaic tiles), it still makes a good teaching example about how to choose a grout color for your own mosaic for these reasons.
- Randy worked through the decision in a thorough way using basic methods BEFORE testing colors in hidden places in the backsplash.
- Randy took some good photos of his experiments, plus one of the installation as a whole that shows the importance of hue in making a backsplash work with the room’s color scheme.
You could use the same approach for picking out the color mortar you wanted to use for a stone or masonry surface.
TIP: You can minimize the color impact of grouting glass mosaic by using smaller grout gaps. It also makes grouting easier. Highly recommended.
CAUTION: A grout gap is needed in architectural mosaics because the grout is needed to seal out water, which can’t be sealed out merely by making the tiles touch each other.Continue reading
