Mosaic Tile Mounting Grid 3/4-Inch (20mm)

Mounting Grid for 3/4-Inch (20mm) Glass Mosaic Tiles is for temporarily mounting patterns of uncut tile to mounting paper for rapid installation using the indirect method. These are not needed for most projects. Most artists use cut tiles or glue each tile directly on the surface they are covering and do not need grids.

The grid mounts 225 glass mosaic tiles (3/4-inch size) on a 1.15 square foot piece of mosaic mounting paper in a uniform grid of 15 x 15 tiles with a standard grout gap of approximately 1/16 inch.

Note that sockets of the grid has bevels at the edges which match those on the bottom edges of glass mosaic tile, such as found on most varieties of 3/4-inch metallic glass and vitreous glass tile. In other words, the grid might not work as well for 3/4-inch tile which is completely flat on the bottom, such as might be found on stone tile or porcelain tile. With the flat-bottomed stuff, you might have to be a little more careful to keep the tiles from popping out as you apply the mounting paper.

Mosaic Tile Mounting Grid 3/4 Inch

  • grid size: 15 tiles x 15 tiles.
  • grid area: approximately 1.15 square foot.
  • grout gap: approximately 1/16 inch.
  • tile size: 3/4 inch (20mm).

The Indirect Method

Mosaic tile can be glued one at a time DIRECTLY to a surface, or you can lay your mosaic out on a temporary surface in what is called the “Indirect Method.” Temporary surfaces can include things like fiberglass mesh, paper, adhesive contact paper or trays filled with lime putty. Our grids were made to work with self-adhesive mounting tape or mounting paper that is glued to the faces of the tiles.

Why Use The Indirect Method

Why would you want to use the Indirect Method? It is easier to lay up your mosaic design at your work table than it is to lay it out on a floor or vertical wall. Also, you can work for days or weeks at your work table laying up the mosaic without tying up the location where the mosaic will actually be installed. Again, none of this is necessary for a beginner laying up a small craft project like a trivet or a mosaic mirror.

Use In Mosaic Art

The following is how to do the indirect method using our grids and mounting paper:

  1. Place glass mosaic tile into the grid face up, filling up the grid with your design.
  2. Dilute water-soluble glue such as Elmer’s Glue with 3 parts water to 1 part glue.
  3. Paint the water soluble glue onto the mounting paper using a small artists paint brush. Use a light coat to avoid wrinkling the paper.
  4. Lay mounting paper onto the face of the tile, careful to avoid wrinkles.
  5. Allow sheet to dry completely and remove from the grid.
  6. Spread thinset mortar or mosaic adhesive on the surface to be mosaiced.
  7. “Butter” the bottom of the sheet of tile with the same mortar or adhesive. Of coarse, you butter the bare glass bottoms of the tile, not the paper.
  8. Press the sheet of tiles into the adhesive-covered surface with the PAPER ON THE OUTSIDE.
  9. Allow the thinset or adhesive to cure for 24 hours.
  10. Mist the paper until it is soaked and peel it off the tiles.
  11. Grout the mosaic.

BULK Mounting Paper – 1000 Sheets

BULK – 1 Full Box of 1000 Sheets of Mosaic Tile Mounting Paper

Original Product description for the smaller 10-sheet bundles follows below.

Mosaic Tile Mounting Paper 1000 sheets is for temporarily mounting mosaic designs for rapid installation using the indirect method. These are not needed for most projects. Most artists glue each tile directly on the surface they are covering and do not need mounting paper. The paper can be used with or without mounting grids and can be used with cut pieces of tile as well as whole tiles. The paper is 1.15 square feet. Note that the paper isn’t ordinary brown wrapping paper or even brown kraft paper. It is especially designed to resist wrinkling and tearing when wet, and anyone who has tried to use ordinary brown kraft paper for mosaic mounting can tell you this is essential.

BULK Mosaic Tile Mounting Paper 1000 Sheets

  • 1.15 square feet per sheet
  • resists tearing and wrinkling when wet
  • this paper is not self-adhesive (see instructions below)
  • 1000 sheets

Mosaic Glass Cutter (Wheeled)

The Mosaic Glass Cutter is the recommended hand tool for cutting glass mosaic tile. This tool cuts glass up to 3/8-inch thick with minimal crushing and splintering, and it easily cuts molded tile into quarters, halves and triangles. It is also great for nipping up small pieces of stained glass, although it is not a scoring tool for making long straight cuts in stained glass. This is a compression tool similar to an ordinary tile nipper in the sense that you squeeze tile between the blades. Note that the circular blades do not actually rotate. Replacement blades are available, although the blades should last for years if you don’t abuse them by attempting to cut materials other than glass.

You should not use ordinary tile nippers to cut glass tile. Ordinary tile nippers were made for glazed ceramic tile, and they tend to crush and splinter glass. For most artists, the mosaic glass cutters tend to pay for themselves in what they save in wasted tile.

Safety and Cutting Tile

  • Always wear safety glasses with side shields when using the cutters.
  • Make sure that you don’t cut glass around people not wearing safety glasses. Flying chips could potentially hit their eyes as easily as yours.
  • Never use a mosaic glass cutter to cut materials other than glass, especially hard porcelain. The wheel-shaped blades can shatter.
  • Be aware that cutting glass tile can produce sharp tiny slivers. Never sweep off a work surface with your bare hand. Use a vacuum or counter brush.

Product Specifications

  • steel hand plier with cushion grip
  • replaceable carbide steel cutting blades

How To Cut Glass Tile

Hold the cutter over a cardboard box or plastic dishpan to catch broken pieces and tiny slivers.

Hold vitreous glass tile upside down when cutting so that you can see the embossed pattern of ridges on the bottom. Make sure you position the blade so that the ridges do not interfere with it. It is easier to cut across a ridge or in a crease between two ridges than it is to try to cut with the blade on top of a ridge where it can slip off.

Efficient Cutting

It is much easier to cut up four or five pieces of tile and choose the one that fits best than it is to try to trim one piece to a certain shape or size. It is quicker too. Keep your rejects in a small pile and pay attention to the shapes that are in it. If you don’t use a certain size or shape as often, try to cut fewer pieces like that. This is much more effective than trimming a piece down to what you need, and it is a lot less tedious.

Replacement Springs

Replacement Springs are available, but your cutters are not defective or useless if the springs fall off. The springs tend to fall of all hand tools eventually, even the most expensive brands. Keep your pinky fingers inside the handle instead of outside with the rest of your fingers and use that to open the tool. This is basic shop/studio practice for using any type of plier tool, most of which do not come with springs in the first place.
