Free Mosaic Pattern Horse fits the 6×6-inch mosaic backer board we sell and can be transferred onto the board using these instructions in our blog article. Carbon transfer paper may be easier than coating the entire back of the pattern with charcoal because there are so many lines to be transferred.

Prints on 8.5 x 11 inch paper.

This pattern was designed using the 12mm (~1/2 inch) Elementile Recycled Glass Mosaic Tile.

Mosaic Tile Needed

The more closely you attempt to fit the tile together, the more tile you will have to scrap because they don’t always cut exactly as desired. It is easier and more efficient to leave a grout gap. You need a grout gap to properly seal out water.

These numbers are inflated to account for cutting scrap. In theory, you can cover the entire pattern in 144 UNCUT tiles with barely a gap. These numbers at their high end add up to 288 tiles, and 216 tiles at their low end. It’s better to have tile left over for other projects, especially if you aren’t sure how steady your cuts will be.

No Partial Bags Sold

We cannot sell partial bags of tile. Of course you will have many tiles left over if the color is only used in 2 or 20 tiles! That is a good thing. You build a library of materials at home that you can be used for other mosaics, hopefully your own designs. We plan to offer kits soon that include the quantities listed above, but until time permits that work, please do not email us asking for partial bags.

Mosaic Art Edges

This pattern mounted on the 6×6-inch backer board produces a mosaic where the tiles extend all the way to the edge of the board so that edge of the mosaic looks like what it is (an authentic mosaic).

However, the tile needs to stop at the edge of the backer and not stick out. If unframed, the outer edges of the glass tile need to be smoothed by rubbing with a fine-grain stone of moderate hardness, which can be found on the ground or streets most places, or by using the fine-grain sides of a ceramic marble file or a dual-grit rubbing stone. Rub finished mosaics with care and practice first by rubbing sharp tiles before you glue them down. (I have used ordinary found stones for this purpose -JM)

Fits In Standard Frame

A finished 6×6-inch mosaic made with glass tile on our backer boards should have the same dimensions and thickness as a 6×6-inch stretched canvas painting, and so it can fit in a standard 6×6-inch gallery frame meant for paintings.

Displaying Mosaics Unframed

Many books and authorities recommend NOT extending the tiles all the way to the edge of a backer because it makes those tiles vulnerable to damage by impact and by leaning the mosaic on its edge. We have observed that the 6×6-inch size is small and light enough to be handled without these types of damage being as much of an issue provided the mosaic is handled with care. Also, we think the raw mosaic edge is a vital part of the look and feel when displaying the finished artwork.

How To Make An Aluminum Frame

Mosaic wall art often takes the form of rectangular “plaques” which, visually, serve the same function as rectangular paintings on canvas. Paintings often look best when they have been framed properly; this can also be true for mosaics.

Paintings are usually framed with some kind of stained wood. This can be done for mosaic art as well, but this tutorial will show how to use another attractive option: angle aluminum. Aluminum might sound daunting at first, but with some common hand-tools a clean and sharp frame can be made for your mosaic. Aluminum is also nice because it doesn’t rust and the metallic shine nicely compliments glass.

Part I: Framing a mosaic that has not been grouted yet

Step 1: Preparation

Installing an aluminum frame is easiest when the mosaic has not yet been grouted. However, it is possible to put a frame onto an existing already-grouted mosaic using similar techniques. This tutorial will first demonstrate how to frame an un-grouted mosaic.

Angle aluminum is readily available in three sizes: 1/2 inch, 3/4 inch, and 1 inch. In my experience the 1/2 inch variety would be unsuitable for most of my artwork because it would be hard to get a screw into the side of it, and it wouldn’t provide a nice lip beyond the surface of the mosaic tile. 3/4 inch angle aluminum is big enough for most projects. Because of its size and weight, 1 inch angle aluminum is only suitable for mosaics whose base is at least 1/2 an inch thick, and should not be used for smaller projects.

The first mosaic is an abstract pattern made of stained glass triangles glued with Weldbond onto a composite backer made of half-inch thick concrete backer board (CBB) and quarter-inch thick plywood. The total thickness of the backer is therefore 3/4 of an inch which is suitable for a 3/4 inch angle aluminum frame. The frame will need to sit a little higher than the glass, so the frame will rest solely on the CBB. The second mosaic is larger and will use a slightly different construction with 1 inch angle aluminum. We have a discussion about how to use concrete backer board as a mosaic surface on our page about ideal mosaic surfaces. Angle aluminum can be purchased in 8 foot lengths at your local big box hardware store. Don’t buy the cheap stuff, get one of the thicker materials seen in this tutorial. The dimensions can be seen more easily in this picture. Notice that each of the “arms” of the “L” are 1/16 inch thick.

The glue needs to be dried before you begin. If you used Weldbond you can perform most of the framing operations as early as three hours after gluing the last tile, but you should still wait 24 hours before grouting. This allows the glue to cure and develop water resistance so that it won’t be weakened by the wet grout.

Most of the tools used in this tutorial should already be available to you. You’ll want gloves, a hacksaw, a drill, a square, a ruler or measuring tape, screws, a metal file, and a marker. Safety glasses should also be worn while drilling. If you have a chopsaw in your garage or work room then you can use that instead of the hacksaw as long as you have a blade suitable for cutting metal. Aluminum is soft as far as metals go, so doing it by hand isn’t that difficult. You should wear gloves to protect your hands from the saw and from the metal file. A small slip with a file can actually take off quite a bit of skin so be careful.

Step 2: Measure the first piece

For this mosaic we will cut sections of angle aluminum at right angles and have two “inside” pieces butt up against two “outside” pieces. With a chop saw a mitred frame can be produced, but mosaic artists with only a hacksaw should stick to right-angle frames instead.

We will make one of the inside pieces first. When they’re completed it will be easy to make the outside pieces. Making the first inside piece is the hardest part of the project, so take your time and measure twice. Lay the aluminum flush with one edge of the mosaic, and then use a marker to draw the cutting line. When you cut bias the saw towards the outside of the mark because you’ll have to file it down.

Use the mosaic to get the length.

Lay the angle on the table edge for cutting.

Step 3: Make the first cut

When cutting with the hacksaw be sure to make many long but shallow strokes. Aluminum is tougher than wood, so you need to take it slow. It also helps if you clamp the aluminum to the table. Remember to leave some extra lenghth because you’re going to have to file the end later.

Step 4: Clean up the edge

After cutting the edge will be very sharp and dangerous. It must be filed down. Sandpaper is not ideal, it will get shredded by the aluminum and you risk scratching the surface that you want displayed. The marker can be wiped off now, but if it has set too long it might be dry. If that happens and water can’t get it off just hold the end of the bar in bleach for 15 seconds then wipe it on a rag.

Remove dried marker by dipping in bleach.

Step 5: Measure in for screws

With our first piece cut we can now attach it to the frame, but the screws need to be positioned properly. Screw positioning depends on the dimensions of the angle aluminum and the thickness of the mosaic.

For this mosaic the screws will be put two inches in from each end, and then lined up so they go right into the middle of the CBB. It is better to have the screws go into wood than CBB, but for a small mosaic like this the CBB will suffice.

measuring screw hole location

For this mosaic we will align the frame with the backer plywood.

Step 6: Determine screw depth

We want the screws in the exact middle of the CBB so that they don’t damage it. With the angle positioned even with the CBB/plywood transition that means the screws are going to go 1/4 of an inch away from the lip of the angle aluminum. This gives us a nice gap above the surface of the glass.

This is how the thickness of the mosaic breaks down.

The screw should be in the middle of the CBB, or 1/4 inch into the frame.

Step 7: Drill pilot holes

Mark the screw holes and clamp the bar of angle aluminum to the work surface. Drill pilot holes with a 1/32 drill bit before drilling out the actual hole size. The actual size is going to be determined by the type of screws you use.

Step 8: Drill the holes larger

Once the pilot holes have been drilled choose the appropriate drill bit and then drill the holes larger. Then check for burrs around the drill hole on both sides. They should be cleaned up before installing the frame piece.

Step 9: Attach the first piece

Line up the angle piece with the mosaic where you want it mounted. Drill through the holes into the CBB, but whatever the length of the screw is subtract about 1/4 inch. This doesn’t have to be exact. Screw the frame piece to the side of the mosaic.

Screws might leave another burr, you can back them out and file if you want.

The first frame piece is installed. Don’t worry if it doesn’t sit 100% flush with the mosaic.

Step 10: Make the opposite piece

Repeat steps 2-9 to produce the next piece. Screw it on opposite the first piece, in the same manner as shown above. You can check for accurate fitment by taking the mosaic and resting it sideways on the table to see if your frame pieces line up properly, or you can use a square.

Everything needs to line up flush or else the next two pieces won’t fit properly. You can play with the angle at which the screws are drilled in and with tightening or loosening them to adjust the frame. This frame has two screws per side, but for larger pieces you might want to go with three screws. If you do that it can help to get the middle screw figured out before attaching the screws near the edge.

Make and install the second piece.

Step 11: Make one of the sides

Using steps 2-9 make one of the side pieces, but this time you need to allot enough extra length to accommodate the width of the two pieces you just installed. Now that the other two pieces are already in place you can flip the mosaic upside-down when you go to pre-drill the screw holes in the sides of the mosaic for the frame piece.

Make the side pieces the same as above, but include the width of the frames.

It’s easy to install sides when the piece is upside down.

Step 12: Make the other side

With three pieces down, simply copy the piece you just made for the other side and install it. The frame is now complete.

Step 13: Fill in gaps if needed

If the mosaic backing was cut by hand (as this one was) there might be some small gaps between the frame and the mosaic. These gaps can be filled with Weldbond before grouting. If you do this wait 24 hours before grouting so the glue can dry. I glued the seam and then pressed the glue in with my index finger, wiping the excess onto a paper towel.

Small gaps may be present between the frame and mosaic backer.

Weldbond can be used to fill in gaps.

Step 14: Grout your mosaic

The final step for the frame is to grout the mosaic. If the frame is installed before grouting it saves lots of trouble later.

The grout I use in this tutorial dried rather quickly because it was done in a warm environment, but exposure to wet grout can stain some aluminum trim pieces because of a mild chemical reaction. It’s best to mask the surface of the frame to prevent contact with wet grout.

You’re Done!

At this point the frame is complete and the mosaic is grouted. All that remains is to put a hanging wire or hook on the back and sign it.

Part II: Framing a mosaic that already has grout

Framing a mosaic which has already been grouted with an angle aluminum frame is not ideal!! You should try to decide whether or not a mosaic will get a frame before you grout it, or you should look at using some kind of trim wood with a lip to make a mitred frame which covers the edges of the mosaic.

That being said, you may find yourself in the position I found myself in when I decided to make this tutorial. I had a mosaic I was very proud of, but after grouting it I realized that the way I had planned to deal with the edges just wasn’t going to look as nice as I wanted it to. I could tell that this piece needed a nice clean frame and I had to do it even though the grout was already in place.

Part II shows how to install a frame made out of 1 inch angle aluminum onto a stained glass mosaic whose backing is a little over 1 inch thick. You will follow the same steps as Part I, but make accommodations for the larger size of the mosaic, the new size of aluminum, and the deeper thickness of the mosaic backing.

Building the Frame

This mosaic is mounted on 1/2 inch concrete backer board as was the previous mosaic, but this time the wood backing is much thicker. Between the wood and the larger aluminum we are able to screw directly into the side of the wood.

You can see in the diagram that the aluminum overlaps the wood by about 5/16 of an inch, yet still has a nice lip above the glass. We’re putting the screws about mid-way through this overlap directly into the wood, or about 5/32 of an inch from the edge of the aluminum. The piece is also larger so you may notice that there are three screws each on the top and bottom. I installed the middle screws first.

The screws will be set approximately 5/32 of an inch away from the edge of the aluminum.

Build the frame as detailed in Part 1. More screws might be required.

Grout the seams

Once the frame is constructed you might find that there are gaps along the edges. These gaps can be filled with grout. Mix a small amount of it and try to work only around the areas that need it. You might find that one side is already flush with the frame and doesn’t need any grout. Be sure to clean out the grout properly so that it lays flush with the grout on the mosaic so it looks nice.

All Finished!

Once again your mosaic is essentially complete and all you need to do is put some mounting hardware on the back. Enjoy your new mosaic.

Mosaic Tips and Instructions

All of our online mosaic content was written by a professional artist who also holds an engineering degree and has worked in a materials testing laboratory.

Beware Of Questionable Information

There is quite a bit of instructional material online, and a lot of it is questionable, particularly when it comes to crafts. All too much of it was written merely to drive sales without regard to durability or longevity. For example, you can see websites recommending the use of water-soluable glues to attach tile to terracotta flower pots, which is problematic for several reasons and not likely to last. For comparison, here is something our mosaic artist wrote about potential problems with mosaic flower pots and how to fix them.

Nitrile Gloves Disposable 9.5-Inch Medium 1 Pair

Disposable Nitrile Gloves

Nitrile Gloves Disposable 9.5-Inch Medium 1 Pair are powder-free, latex-free 4 mil thick examination gloves for detailed work with thinset mortar and Weldbond adhesive. These are more durable than the latex gloves we used to sell and allow the wearer more dexterity than our heavy-duty grouting gloves.

Nitrile Gloves Disposable 1 Pair

  • material: nitrile
  • 1 pair
  • size: medium 9.5 inch
  • weight/gauge: 4 mil
  • color: blue
  • powder-free
  • latex-free

When To Use These Gloves

These gloves can keep your hands and fingertips clean when working with thinset mortar for an extended period, but they are thin and fragile and will not protect the hands from cuts. For that reason, you would NOT use these gloves for grouting, which involves a lot of rubbing and wiping over the surface of the mosaic and exposes the hands to sharp edges. For grouting, we recommend the Heavy-Duty Grouting Gloves, but even those can be sliced by a jagged piece of mosaic tile. Tip: It is better to keep grout gaps fairly narrow to make grouting easier and prevent fingertips from getting in between tile where they can be cut.

We use these gloves at our studio for making found-object mosaics from artifacts and thinset mortar, which involves a lot of careful positioning of small objects in concrete. The gloves are thin enough to not interfere with dexterity, yet they still keep the mildly caustic mortar from contacting the skin and drying it out. Some people also wear these gloves for working with Weldbond adhesive, but that is merely based on preference and not safety. We have never observed any problems with Weldbond on the skin, even when in contact for long hours day after day. Weldbond is a water-based adhesive and was selected by NASA for use in space because it is non-toxic.

Tip: Talcum powder can be used to help get the gloves on and off. We keep a dispenser of baby powder in our studio for applying to our hands before inserting them into gloves. Without the powder, the sweat from the hand makes getting the glove off a lot more difficult.

When and How To Use The N95 Comfort Dusk Mask

Keep in mind that dust masks are only part of a strategy to prevent breathing dust. You should also mimimize the amount of dust you generate by pouring and mixing carefully and using spray bottles to mist the grout as you mix it.

The masks are not individually wrapped, so keep the box closed during storage to prevent incidental contamination.

Vacuum off used masks before storing them in individual Ziplock sandwich bags labeled with the student’s name.
