The Right Way To Install A Metal Mosaic Backsplash Tile

November 05, 2018


A mosaic backsplash featuring metallic backsplash tile adds depth and character to a bathroom or kitchen. In fact, it’s one of today’s hottest trends in interior design — and there are many colors and patterns to choose from. 


For the most part, installing a mosaic backsplash with metallic tile is no different than any other tile. However, if you’re planning to install your backsplash mosaic as a DIY project, there are a few tricks for installing wall tile you should learn, especially before working with metallic tile. Knowing a few “insider tips” about proper preparation and what tools and materials are needed will prevent some unpleasant surprises.

The major difference is grout. In fact, with metallic tile you may not even need grout at all, unless the metallic backsplash tile is included in combination with other types of tile, such as stone and ceramics. If you do use grout, it’s important to pick a non-sanded grout, because sanded grout can scratch the metallic tiles. Choose a latex-additive cement-based grout.

Cutting Tile

Most of MSI’s metallic backsplash tile mosaics are pre-assembled on mesh backing for simple and quick installation. There may be times when you need to cut tiles to fit in a tight space, make an opening for a light switch, or create a straight edge. To cut metal tiles, you’ll need a tool approved for that purpose. This will be a carbide or diamond blade installed in a hacksaw or band saw. Make sure you’re comfortable using one before beginning your project; a tool rental company should be able to provide guidance.

A latex-additive thinset mortar is recommended for metallic backsplash tile mosaics on a vertical surface. You can also use silicone- or urethane-based adhesive. Follow the manufacturer’s directions closely — some mortar is meant to apply to the wall with a trowel, and other types should be applied to the back of the tile.

First, make sure you have all of the supplies you need handy. You’ll need a V-notch trowel for applying mortar, a clean sponge, a rubber grout float, buckets for mixing grout and mortar, enough grout and mortar to finish the job, and a tile cutter if needed. The basic steps are as follows:

1. Make sure the kitchen backsplash wall surface is totally clean of grease and dirt — this could prevent the mortar from sticking.

2. Use painter’s tape to mask any surfaces you need to protect, such as cabinetry.

3. Measure your backsplash area carefully, making marks where the tile will go. Use a level to make sure it’s lined up properly.

4. Prepare your mortar according to the instructions on the package. Apply it to the wall (or back of the tile, depending on which type of mortar you use) with the trowel, making sure it has a uniform depth.

5. Apply mosaic tile sheets to the mortar, carefully lining up each sheet with the next. 

6. Before mortar sets, you can shift tiles slightly if needed in order to fit them perfectly in the space.

7. Wait 24 hours to let the mortar set, then use a non-abrasive brush to remove excess mortar from the tile. 

8. If you are applying grout, prepare it according to package instructions and apply it with the grout float. Make sure the grout fills in every space between the tiles fully. 

9. Wait 15 minutes to an hour, then remove excess grout from the tile with a damp sponge.

10. Wait 12 to 24 hours for the grout to cure, then use a damp sponge to remove any remaining grout haze from the tile backsplash surface.
