Making DIY tile coasters is super easy with cork backed adhesive sheets. These adhesive backed cork sheets are 4 inches wide by 4 inches wide by 5/64 inches thick. When installing these on tiles you may need to trim them. Normally, 4 inch wide tiles are less than 4 inches wide to account for spacing where the grout is installed.

I purchased four inch square travertine tiles to use as coasters. To prepare the cork backed adhesive sheets I had to trim off a little more than 3/8 of an inch from two adjacent sides . That way it would fit on the back of the tile without sticking out. I removed the adhesive backing from the sheet and centered it on the tile and installed it.

Typically I do this on a crafting mat but this is on top of my anti-static mat that I use for electronics and PC assembly, which is fine because it is resistant to chemicals.

Making a DIY Tile Coaster

For our friend’s birthday I took one of his common sayings “Let’s make a bouncing baby BOYYYYY!!!!!” and typed that saying into the Cricut editing software and sized it so it would fit within the profile of the travertine tile.

Making DIY tile coasters using cricut editing software to create an image to be cutout on vinyl.

Then I sent that file to the Cricut to cut it out.

And applied the cutout to the travertine tile and weeded out all of the vinyl to be removed. It wasn’t perfect since I had to double back and add the letters again so you can see some are not in line. But the good news is that the gift was well received.

Preparing travertine tile for cork

Note: The back side of the travertine tiles are not polished as they are meant to be mounted on the wall. That’s the side you want to install the cork onto. The also have dust and dirt on them. So I cleaned the tiles with water (do not use soap) to remove any of the dust. Then I set the oven to 200 degrees, let it heat up then turned it off. I placed the tiles in the oven on the rack to help the drying time. Two days later I grabbed the tiles out of the oven. Then I readied them for installing the cork backed squares onto the back side of the tile.
