Steps
Step 1

Firstly, find yourself a base for the coasters.
I had some old timber coasters that I wanted to refinish but you could use some off cuts of timber also. I also had a larger timber lid to a candle that I wanted to add tiles to.
Lightly scuff sand the surface to remove any debris and to roughen the surface which will aid the adhesion of the tiles.
Step 2

Then plan out the area to be tiled. You might need to trim some edges to fit the base. I used these white penny rounds and I cut some of them to fit the larger round base.
Step 3

Then you can apply the tile adhesive. I like to use this premixed adhesive which is great for smaller projects. I used this adhesive spreader to apply a thin layer. I then laid the tiles and pressed firmly. Then removed any excess using a damp sponge.
Leave this to set for at least 24 hours.

Step 4

You can now add the grout. Again I like to use this premixed grout when doing small projects. It has a thin nozzle which makes application into all the gaps very efficient. I added the grout around the edges of the timber as I didn’t want the timber visible.
I then used the damp sponge to press and smooth the grout evenly.
Then it’s time to set for another 24 hours.
Step 5

Once it’s set, you can wipe any residue with a clean damp sponge.
I sealed this using a white wax which gives the grout a nice smooth finish and also makes cleaning a lot easier.
Step 6

I love how these turned out. There are so many possibilities with this. You can use any type of mosaic tiles and get really creative with the designs.
