How To Resin Mosaic

Covering mosaic tile (and other embedded objects) in ArtResin is easy! 
In fact, ArtResin takes mosaic artwork next level - not only can you use it as an adhesive to mount your tiles, but it also enhances the texture of your mosaic with a glossy finish that'll make you want to reach out and touch it!


We love using wooden art panels here at ArtResin - you can mount your artwork and pour your resin directly on the panel!  Some panels even have a raised lip specifically designed to contain resin - they make for a super easy pour with clean edges.

Measure, mix, pour, spread, cover and wait, and in 24 hours your mosaic will go from good to gorgeous!

Let's get started ....

1. Assemble your Mosaic Tiles

First, assemble your mosaic tiles. You may choose to draw a design outline directly onto the wood panel before you start (as we did) or you can simply freehand your design. 

💡 TIP: being an organic material, the wood panel may contain trapped air which can release into your resin as bubbles. There are many variables that can affect gas bubbles: the type of wood, how dry the wood is, humidity etc. Sealing wood with paint, or a spray/brush-on sealant or acrylic paint is an option to help to prevent bubbles. We've used these wood panels enough to know that we don't need to seal them, but we always recommend testing with your particular materials so you know exactly what results to expect before you resin your final project. Again, if in doubt, you can never go wrong by sealing first if it makes you feel more comfortable.

2. Calculate how much Resin you can use

Next, using our Resin Calculator, simply enter the length and width of your piece to determine how much ArtResin you’ll need.

💡 TIP: a standard 1/8" or 3 mm layer for a 12 x 12" panel requires 5 oz resin (2.5 oz resin and 2.5 oz hardener). Measure the lip on your panel as they can vary. The panel in our video, for example, has a 1/4" lip. If you'd like to fill the panel up to the top, you'll need double the amount: 10 oz total resin (5 oz resin and 5 oz hardener).

3. Stir Thoroughly

Wearing gloves, measure accurately ( by volume ) precisely equal amounts of resin and hardener. Stir thoroughly for 3 minutes total, ensuring you scrape the bottom and sides of your mixing container as you go. 

💡 TIP: for our very best measuring and mixing tips, read the blog How To Measure And Mix Resin And Hardener.

4. Pour the Resin

 Pour the ArtResin onto the centre of your piece and spread it out to the edges using a spreader. This will give you a 1/8" (or 3 mm) layer of ArtResin into which you'll lay your tiles. You'll have about 45 minutes of working time before the resin gets too thick to spread. Read our blog How To Pour And Spread Epoxy Resin for more resin tips and techniques!

💡 TIP: Be aware that ArtResin makes items look wet, so it may darken natural objects like terracotta tile etc. If you test your objects first with water, you'll know exactly what appearance you can expect once you pour on the resin.

Now you're ready to drop your tiles into the 1/8" layer of ArtResin you've spread onto your panel.  ArtResin is an adhesive, so it will keep your pieces mounted to the board once it cures. Once all of your tiles have been mounted and the design in complete, you're ready to torch.

5. Use your Artist Torch 

Using your Artist’s Torch, hold the flame a couple of inches above the resin surface just long enough to pop the bubbles, keeping the torch moving from side to side at all times.
💡 TIP: if you're nervous about using a torch, don't be! Read our blog with all you need to know about How To Use A Torch On Epoxy Resin.

6. Final Check of your Artwork

Once the piece has been torched, look at the resin in the light for any missed bubbles, tiny hairs or bits of dust, using a toothpick to fish them out.

7. Cover your Artwork

With a plastic tote or a cardboard box ( with the flaps cut off ) cover your piece and let it sit for 24 hrs until it’s dry to the touch.

8. Wait 24 Hours

After 24hrs has passed, reveal your piece!  

💡 TIP: the resin will be dry to the touch at the 24hr mark.  At this point, you're free to hang and admire your artwork on the wall, absolutely, but if you're planning on packing and shipping your artwork, please wait at least 72hrs until the resin has fully cured.
