How to apply clear mosaic tiles
Mosaics are works of art created by using glass or ceramic tiles and grout to make a picture. Mosaics adorn the ceilings in cathedrals with elaborate details, but they can be found in a simple pattern on the coffee table in your home. With practice, you can create a custom mosaic all your own.
To make a mosaic, start by getting some pieces of glass, stone, porcelain, or any other material you want to use for your mosaic. Then, find a surface to create your mosaic on, like a table, a planter, or a walking stone.
Once you have your materials, mix some mortar powder and water in a bowl and apply the mortar to the base you chose. Press the pieces into the adhesive in whatever pattern you desire and let it dry for 24-72 hours. Finally, apply grout in between the pieces and seal the mosaic with varnish.

Pick the base to glue the mosaic tiles on. You can make a mosaic on nearly any surface. It should be strong enough to handle the weight of your mosaic pieces and the glue and grout. Tables, planters, bird baths, or walking stones are all great options. Use a damp sponge to scrub off any stubborn debris. Dry the base completely before you start applying the mosaic pieces to it.
Your base can be any shape, but be careful with very extreme curves because you will need very small mosaic tiles to fill the curves. The best mosaic base for outdoor mosaics is concrete because it is the most weather-resistant. You can find thin concrete boards at your local building material store.
A mesh metal pizza tray works especially well for making decorative glass gem mosaics. Terracotta bases are more risky for outdoor mosaics since they can be susceptible to freezing damage. If you want to make a mosaic on a terra cotta pot, for example, either take the pot inside in cold weather or apply several coats of sealant when you are finished to protect it from the elements.
Select the material you want to use to make your mosaic design. The small pieces of material used in a mosaic art are called tesserae. They can be glass, stones, porcelain, seashells, or anything else you can find. If you are unsure, scatter the pieces across the base. They should be able to cover it fully. If you are reusing materials for your mosaic, be sure to clean off any dirt or debris with soap and water. Let them dry completely before you begin the project.
You can also add other objects or decorations to your mosaic, like small ceramic flowers. You can also used smashed china plates as mosaic tiles. Break one plate at a time with a hammer inside a plastic bag. Use a tile nipper to break the plates for more control over the sizes and shapes of the pieces. You can find the gems in your local craft store. They are available in many different colors and sizes. Sketch your design on the base. Copy a mosaic pattern from a coloring book or make your own simple sketch.
Remember that the more detailed the design, the smaller your mosaic tiles will have to be. Lay your mosaic pieces over your design before gluing them down. Make sure the pieces are clean of any dirt or debris before laying them out. You can further break your pieces with a hammer or tile nipper if need be. Choose the right adhesive for the materials you are using.
The traditional mosaic adhesive is cement-based mortar. It is made by mixing cement, sand, and water. But you can also use acrylic based adhesives, epoxy resins, or construction adhesives. Find the right adhesive for you at your local craft supply or hardware store. You will need an adhesive that works well for your base and decoration materials.
For mosaics that will regularly get wet, like shower floors, use thinset mortar. Epoxy resins work well on metals, but they can be messy to use and smelly. Mix your adhesive per manufacturer recommendations, if necessary. Check the label on your adhesive to find out if you need to mix it before applying.
Mortar will need to be mixed beforehand, as will epoxy resins. A tube of acrylic adhesive is ready to use right away. Spread the adhesive on the base with a trowel or spatula. Wear rubber gloves when handling adhesives to keep your hands from getting glued. Spread the adhesive over the whole surface of the base.
Apply the buttered piece directly to the foundation and press down to affix it in place. This also works well if you have an adhesive that comes in a squeezable tube. Arrange the mosaic pieces on top of your design. While the adhesive is still wet, gently affix the mosaic tiles by pushing them into the mixture.
Apply tiles starting in one corner of the design and work across in rows. Let the adhesive set. The time needed varies depending on the type of adhesive you used and where your mosaic will be, so check the label on your adhesive and follow the directions stated there.
Once the adhesive is set, wipe the mosaic tiles with a damp sponge to clear away any extra adhesive material that may have risen to the top. If you wait until the adhesive cures completely usually another 24 hours after it is set , it will be very difficult to wipe off the excess from the tiles.
If you used traditional mortar, 24 hours is usually enough time for indoor mosaics. Outdoor mosaics will need to set for 72 hours. Acrylic adhesives and epoxy resins usually take between 12-24 hours to set completely. Choose your grout. Adding grout, a fine textured version of cement mortar, will fill in the spaces between your mosaic pieces. It also unifies and enhances the design. Grout comes in many colors and you can even color the grout yourself to get the perfect match for your mosaic.
It looks best if you pick a contrasting color so your design will stand out. If you are in doubt about the grout color, black is usually the best choice, and pure white often drowns out the mosaic design.
If you want a lighter color, try a cream-colored grout. Prepare the grout mixture. Mix the grout by following the instructions provided by the manufacturer. Wear rubber gloves, safety goggles, and a dust mask to protect yourself when mixing the grout. Apply the grout using a spatula. Lay newspaper down on your work surface and place the mosaic on it. Cover the whole mosaic with grout, spreading it with a spatula and filling in the creases between the tiles. The grout should cover the mosaic enough to fill the gaps.
Do this outside or in a well ventilated area. Let the grout set and wipe away the excess. Check the label on your grout to see how long it will need to set. It should be set in about 20 minutes. Then, wipe the mosaic with a clean sponge and warm water. Rinse out the sponge regularly as you wipe away grout from the surface of the tiles. Remove big pieces of grout stuck to the mosaic pieces with a non-scratch nylon scouring pad or a small wooden stick.
Apply sealant to the mosaic to protect it. This will coat the tiles and safeguard against damage, especially for outdoor mosaics subjected to fluctuating temperatures and adverse weather conditions. It also will give a high gloss shine that will make the colors stand out. Let the sealant dry before using the mosaic. Apply at least 2-3 coats of sealant to protect outdoor mosaics.
