Make a pretty china mosaic bench for your garden! Follow the steps below or follow along on our Curious video lesson where you’ll learn how to break china into mosaic pieces using tile nippers, lay out your design, glue the tiles down, mix and spread the grout, and buff the mosaic as it dries. Even if you’ve never done a mosaic project before, you can do this.

Hammer
Nail
Large Ziploc bags
Safety glasses
Protective leather gloves
Protective latex-type gloves
Dropcloth
Mixing pail or can (coffee can)
Stirring stick
Spray bottle
Sponge
Spatula or palette knife or putty knife

To Break The China Plate (Optional)
1. To break the china plate using a hammer, place the plate in a Ziploc bag and seal it. Don protective leather gloves and safety glasses. Place the bagged plate upside-down on a hard surface like the garage floor.
2. Hold a nail to the back of the plate and strike it with the hammer. Repeat to break large pieces into smaller pieces. Carefully remove and rinse the best pieces to use on your mosaic.
3. Alternatively, you can break the china plate using tile nippers. Wear your safety gloves and glasses and place the plate in a Ziploc bag. Use the nippers inside the bag. Grip the edge of the plate with the nipper blades horizontal to the edge of the plate. The nippers only need to nip 1/4″ to 1/2″ into the plate. Hold the plate with one hand and bend the plate against the nippers as you squeeze them onto the china. They will create a crack and break the china into two pieces. Repeat to break the larger pieces into smaller pieces.
Making The Mosaic
1. Prime and paint your bench and let it dry. Lay your design out by starting with square tiles around the border. (No need to glue yet, just lay the tiles out to create your design.) Place the tiles 1/4″ to 1/2″ from the edge and place each tile 1/4″ to 1/2″ from the adjacent tiles to save room for the grout. Create a second border inside the first mixing heart tiles and large flattened marbles in with the square tiles.
2. Fill in the center of the design with the broken mirror pieces, the broken china pieces, and the small flattened marbles. Try to get the pieces close together so the grout lines are not too big.
3. Using the Quick Grip, glue each tile down. Let dry.
4. Lay down a drop cloth and protect the sides of your bench with masking tape. Wear a mask if desired and don your latex-type gloves. Mix the grout according to the directions on the package. Blend the grout and water in the coffee can using the stirring stick until it is the consistency of runny peanut butter. (Ours is one part water to seven parts grout.) The grout stays workable for about 15 minutes, so get ready to grout the mosaic.
5. Spread the grout onto the surface of the mosaic right over the tiles. Use a sponge or putty knife to spread the grout around all the tiles. Make sure you apply the grout around the outside edges of the border and in between each and every tile.
6. Check on the grout as it is drying and spray it with a mist of water if there are any areas that look like they are drying faster than the rest. This will prevent cracks.
7. After 30 minutes, use a paper towel or damp sponge to wipe the grout haze off the mosaic tiles. Be careful not to remove the grout from between the tiles.
8. Wait another 30 minutes and buff the haze again. Repeat if necessary.
9. Let the grout dry for 24 hours then seal the surface with grout sealer and a sponge
paintbrush. Let dry.
What do you do if the pieces you have are different thickness’? how do you deal with curved pieces? I don’t want the table top to be bumpy and uneven.
Thanks
Great question Erica! If you want the surface of your mosaic to be level and even, it is best to choose tiles that all have the same thickness. If you have curved pieces or thicker tiles, you might want to save those for a terra cotta pot. Hope that helps!
FYI:
NEVER mosaic ANYTHING on wood if using outdoor.
Tiles will eventually pop off ruining your creation!!!
Wood expands and contracts and is an extremely POOR choose for ANY outdoor mosaic use.
Use cement board or Wedi board instead and your creation should last a lifetime if done correctly!
Thanks for the tips, CJ! We’ve had pretty good luck with our wooden bench and other wooden projects, but we always make sure to seal the wood. Thanks for telling us all about Cement Board and Wedi Board. We’ll check it out! J&K
Hi there,
I purchased a wooden bench for our front entryway…not for people to sit on but more for package delivery, etc. I’ve done some mosaic projects in the past, but never an outdoor one. I only want to mosaic the bench arms arms and part of the back of it to make it more decorative. Do I need to spray it with a wood sealer before I mosaic it? I will also lay the mosaic pieces close together so I don’t have to grout. What is the best sealer to apply when done?
Thank you , in advance, for your help.
Hi Gina,
Sounds fun! It would be good to seal the wood before doing the mosaic. Then we’d recommend using Clear 100% Silicone as the adhesive. You shouldn’t need to seal after if there is no grout. Hope that helps!

Any recommendations for attaching the cement board or Wedi board to the bench? What about mosaic directly on cement bench ?
Our bench came preassembled, but you could screw a board onto a bench before starting the mosaic. And yes, doing a mosaic directly on a cement bench should work just fine! J&K
Wood should never be used as a backer/subtrate for outdoor mosaics, even those kept relatively dry. … Instead of wood, use 1/4? concrete backer board for your outdoor mosaic projects.
You will send many hours creating, and in turn over time your mosiac will get ruined. Wood expands and contracts no matter if it is sealed!
Thanks for your input CJ! We haven’t had any problem, but it’s good to let people know. Especially if a piece will be in direct weather.
Cheers,

Cement is actually the best substrate for outdoors. You can mosiac directly on top. I used it many times.
Great tip CJ!

Cj, thank you for this as I was just trying to figure out if I could do this. I have an outdoor shower with a wooden bench and wooden shelves (pressure treated). Are you saying I could perhaps put the cement or hardy board on top of that, and then mosaic that? Or is this just a lost cause? Thank you!
Oops! Not hardy board- but Wedi board as you mentioned. Thank you!
very clear…going to make one this week as my hubby is handy and made me a nice bench for my garden
Oh that sounds great! What a handy hubby!

Hi. I’m loving your tutorials! I just found your site while prepping to try my hand at mosaics. I found a beautiful mirror with a mosaic frame at a flea market but some of the tiles are missing. I think I can now confidently replace them thanks to you!
My question today is about grout. The piece i have does not appear to have been grouted. It actually looks pretty good without grout but do you think I should finish it with grout? If so, can you recommend a lightweight griut ? The piece is pretty large and heavy already so I worry about adding too much more weight before hanging.
Thanks so much!
Janet
If it looks good without grout and all the pieces seem to be properly adhered and aren’t popping off, you might just leave it without grout. Sometimes grout covers some of the tiles and doesn’t look as pretty as ungrouted. Plus grout is very heavy!
J&K
would this technique work on a concrete bench, too?
Hmmm…we haven’t tried it on concrete but it could work. Can you do a test like on a cinderblock to see if the adhesive holds?
Let us know what you find out!

Do I need to prime and/paint a concrete outdoor bench prior to my mosaic design?
We think you should be fine applying the tiles and grout directly to the concrete. But if you have trouble getting the glue to stick, you could seal it.

Gorilla heavy duty construction adhesive work on this concrete bench.
I did not have to seal the bench.
Thanks for letting us know! Good tip!

What about any already painted bench? Should I strip the paint and then paint and prime? Or do it over it? If so what should I strip it with?
An* already painted….
Hi Allyson, The only concern with an already painted bench is that the paint could peel away from the bench and thus the mosaic would come loose. If it seems fresh and secure, you could seal the paint and go from there. Otherwise, you may want to sand the surface and prime it before starting the mosaic. Sanding should be enough without having to strip it.
Hope that helps!
