Broken Millefiori Bouquet Mosaic Coaster Before Grouting.

Broken Millefiori Mosaic Coaster

Leave a reply

I made a mosaic bouquet coaster using our Broken Millefiori and Morjo 12mm Recycled Glass Tile. I used clear contact paper to lay out my design so that I could improvise without a pattern and make revisions as desired BEFORE glue is involved.

I wrapped the contact paper around the backer temporarily so that the design I laid out would be the exact same size as the backer.

I could have just traced the outline of the coaster on a piece of paper and taped the contact paper over the square outline.

Either way, the sticky side of the clear contact paper has to be showing because that is what is going to provide the little bit of stickiness required to keep the tiles from sliding around.

Mosaic Mounting Tape

Mosaic Mounting Tape is clear and sticky like clear contact paper, but the adhesive is MUCH stronger (although still temporary/removable).

Once the design was completely laid out, Mosaic Mounting Tape was pressed onto the face of the mosaic and rubbed to ensure it is securely stuck to the tape.

Then the mosaic is lifted off the clear contact paper.

Apply Glue To Backer

Spread mosaic glue evenly onto the backer. Use a high-quality white PVA adhesive, such as the Weldbond we sell.

Make sure to follow the coaster’s instructions to avoid warping the backer with too much glue. It helps to seal the coaster with a minimal amount to glue a day or two before mosaicing.

Press Mosaic Into Adhesive

I prefer to turn the mosaic face down so that the backs of the tiles are showing, and then press the glue-covered backer down onto the mosaic.

Marble Mosaic Restoration Project

3 Replies

At the end of 2019 Mosaic Art Supply was e-mailed by a local homeowner about repairing a stone mosaic that was being displayed outdoors.

The design of the mosaic is a smaller-scale interpretation of the “Tree of Life” mosaic found in the bath of Hisham’s Palace in eastern Palestine. The palace dates to the 700s and today is considered one of the most important examples of Islamic architecture in Palestine. This particular mosaic was most likely made in the 1990’s.

Natalija Moss writes up the process she and Angela Bortone performed to restore the mosaic:

Initial Conditions

The mosaic measures approximately 4 feet by 4 feet. It was suffering from water damage. The backer was disintegrating, tiles were popping off, and the surface of the mosaic was beginning to warp and wrinkle. The steel frame around the mosaic was thoroughly rusted, with holes in some places. The edge of the mosaic was stained with rust in several places.

Detail of initial conditions before restoration work. There are stains along the edge of the mosaic and multiple spots where tiles are missing. The photos don’t show it well, but the center of the tree was becoming as wavy as the backer deteriorated beneath it.

I felt like the mosaic was repairable, but I would need some help. I contacted local muralist Angela Bortone, who used to work at Mosaic Art Supply, and together we decided we would tackle the restoration.

Color Constraints and Background Colors

5 Replies

Many artists like to choose background colors after the central figures have been tiled.

It is best to tile from the middle and work toward the edges to avoid awkward spacing between at key focal points, but you should not leave the color choices for the background as a complete afterthought.

Nor should you have firm color requirement for the background and tile the central figures without placing that color next to them just to see if they work.

Avoid “painting yourself into a corner” by doing a lot of cutting and mounting without thinking ahead.

“Thinking ahead” can be as simple as placing a single tile next to what you are tiling now to see if it has adequate contrast.

Changing Grout Color With Paint

8 Replies

The following method is only recommended for dry indoor mosaics. Artist Megan Adams recently used it to save a mosaic that had been compromised by white grout, which makes tile colors look less intense and the mosaic as a whole “bleached out” in appearance.

We put white grout in bathrooms because it is used as an indicator of cleanliness. It’s use in mosaic art is limited to making your project look like a summer camp project. Avoid it. Consider black or dark gray grout instead to make your colors look intense.

Also keep in mind that traditional sanded grout is lighter in color when it hardens, and so sometimes a light gray or light brown grout can turn out looking like an off-white and cause the same problem as if you had used white grout.

Making Foam-Core Mosaic Backers For Outdoor Projects

6 Replies

Artist Jill Gatwood uses the following method to make water-resistant foam-core mosaic backers for exterior mosaics, such as the Pet Memorial Name Plaques she does for clients who need something that is lighter weight and easier to ship than stone or solid concrete. The method wraps the foam in three or four successive layers of fiberglass mesh and thinset mortar, and that coating is pretty tough, tougher than stone. (The combination of polymer-modified cement and fiberglass can withstand blows that would easily crack granite of the same thickness.) Continue reading →

Mosaics on Steel Mailbox Using Silicone Adhesive

9 Replies

Artist Jill Gatwood has emailed me her procedure for using GE Silicone II to mount mosaic tile to steel mailboxes, and it is outlined below.

Jill’s instructions have convinced me that there are enough mosaic applications for silicone adhesive that we should sell it. Note that we still recommend thinset mortar or Weldbond for mosaics on architectural surfaces such as backsplashes, but for projects such as mosaic  mailboxes or glass-on-glass mosaics, silicone adhesive is preferred.

Jill’s steel mailbox instructions are fairly complete and include recommendations for purchasing the right type of mailbox for the project and modifying it as needed.

Steel Mailbox Instructions

1. Selecting The Mailbox

Jill says that a steel mailbox from the big box home improvement stores or a hardware store will work but you have to check it and make sure the metal is strong and doesn’t flex. (In practical terms, this means you should buy the mid-grade or premium model and not the one made for the bottom of the market.)

Jill recommends getting one that has ribs to strengthen the frame if you need an XL size mailbox. Continue reading →

Prying Tile From Finished Mosaic

How To Pry Up Tiles To Modify A Mosaic

4 Replies

I have often used a small screwdriver to pry up tiles when I wanted to change some detail in a mosaic, but in all of those cases, the mosaic had a grout gap, and it was possible to knock an individual tile out or shatter it without damaging its neighbors, at least most of the time.

But what if you can’t afford to damage surrounding tiles or you have a mosaic with no grout gap? Is it even possible to get tiles up? The answer is yes, and the method involves a wet cotton swab, a dental pick, and a sharpened chopstick.

Cutting Vitreous Glass Mosaic Tile diagonally to make triangles.

How to Cut Diagonal Triangles from Vitreous Glass Tile

3 Replies

Many people report having trouble cutting vitreous glass mosaic tile reliably because of the embossed patterns on the back sides, which can interfere with the blades of the mosaic glass cutter, but if you take simple steps to minimize interference and rotation, it can be done.

What I mean by interference is when the blade slips down into a valley between two ridges instead of staying positioned in the desired line of the cut. Continue reading →

How to Make a Stepping Stone with Scrap Glass

7 Replies

If you work with stained glass over time you can end up with buckets full of scrap. When the pieces start getting too small and irregular, or if there’s just too much of it, you can used them in a stepping stone. This tutorial demonstrates how to make a stepping stone with an abstract pattern. You can also use tiles instead of stained glass scraps.

How to Hang Mosaic Art with French Cleat Wall Mounts

2 Replies

Small mosaic plaques can be mounted on a wall with a the same type of hangers and wires used for paintings provided the nail on which it hangs is mounted in a stud inside the wall, and even then redundant wires and fasteners are recommended. However, larger mosaics need more robust mounting hardware. The “french cleat” is a type of wall mounting that can be used to securely affix heavy mirrors, cabinets or artwork to a wall. In addition to its strength, the french cleat also allows mosaic art to be mounted flush against the wall and makes leveling it easy.

If you built a frame on the back of your mosaic as described in this tutorial, then french cleat molding is a good hanging option.
