Learn to make tile coaster the right way. Here is a post on how to make tile coasters waterproof using a high gloss finish.

How To Make Tile Coasters Waterproof

Last year I started making coasters for my Etsy store and for gift ideas. I loved how they turned out but a few of them were starting to yellow after a few months. I did some digging and found out that I needed to water proof them. The water proofing will protect them from yellowing. The process involves a high gloss finish that you pour over the tiles and it hardens like glass. It’s very easy process and I know you will love how to make tile coasters waterproof.

When you waterproof the coasters or anything you will need to find a location that is away from anything that you can ruin by dropping the gloss solution on it. I kept visualizing it happening to my new quartz counter tops. I am limited in space and I used a large piece of sheet rock to placed on my kitchen countertops.


  • Tile
  • Gloss finish: (Environmental Technology 16-Ounce Kit Lite Pour-On, High Gloss )
  • Printables: Click 1, 2, 3, 4
  • Foam brush
  • Adhesive cork back: ( 4 inch x 4 inch)

Its important that the tile is free from any dust. The tile measures 4 inch x 4 inch and that is exactly the size of the printable image you will need to cut. I found the perfect Mediterranean image. Take the image and with photo shop have them converted into 4 inch x 4inch design. Download them onto my computer and print out. I used a paper cutter which guarantees a perfect cut with no unevenness.

I used a brush to apply the Mod Podge on the printable. You can also apply the glue on the tile itself. Either way works the same.

Apply the printable on the tile and with a clean sponge smooth out all the air bubbles. Then apply a thin layer of Mod Podge over the tile. Let dry for 15 minutes before applying the gloss.

Mix the gloss solutions in a glass measuring bowl in equal parts. I used 2 pounces of each solution for 6 tiles. Read the directions of the Environmental Technology before starting. With a wooden stick mix well. I poured the solution into a old glass jar and used that to pour over the tile.

Before you start pouring the solution place tape on the bottom of the tile. This will prevent the solution from dripping under the tile. Place the tile on a dixie cup or old jar. Pour the high gloss slowly on the center of tile and let the solution spread to the edges of the tile. Use a piece of cardboard to smooth the sides
