How to Epoxy Countertops with Backsplash

Epoxy countertops are a popular option for kitchen and bathroom remodeling projects. Not only are they durable and easy to clean, but they allow you to customize your countertop with endless design options. Adding a coordinating backsplash is a great way to complete the look. Here is a step-by-step guide on how to epoxy countertops and install a backsplash for a seamless finish.

Supplies Needed

  • Epoxy resin kit (countertop kit recommended)
  • Mixing containers and stir sticks
  • Backsplash tiles
  • Tile adhesive
  • Grout
  • Trowels and float
  • Mixing bucket
  • Sponge and rags
  • painter’s tape
  • Denatured alcohol
  • Sandpaper
  • Protective equipment like gloves, goggles and mask

Prepping the Countertop

Proper preparation is crucial for a successful epoxy pour.

  • Clear countertop completely and clean thoroughly. Use denatured alcohol to remove grease and residue.
  • Sand the surface with 120-150 grit sandpaper to help the epoxy adhere.
  • Tape off the edges with painter’s tape for a clean finish line.
  • Mix a small batch of epoxy and use it as a seal coat. This helps prevent air bubbles.

Mixing and Pouring the Epoxy

  • Mix the epoxy according to kit directions, using precise measurements and mixing thoroughly.
  • Pour epoxy slowly and carefully over the countertop. Use a spreader to smooth.
  • Use a torch to pop air bubbles. Make additional pours as needed until countertop is covered.
  • Let cure fully, following manufacturer’s directions. Usually 24 hours minimum.

Installing the Backsplash

Once the countertop epoxy has fully cured, you can install the backsplash.

  • Dry fit tiles and make any cuts before adhering.
  • Mix tile adhesive and use a trowel to spread evenly over the surface area.
  • Press tiles into place, using spacers for consistent grout lines.
  • Allow adhesive to cure fully before grouting, usually 24 hours.
  • Mix grout and apply using a rubber grout float. Push into joints and remove excess.
  • Wipe away residue with a damp sponge once grout has become firm.
  • Remove spacers and allow grout to cure fully before using backsplash.

Tips for Success

  • Work in a well-ventilated area and take safety precautions.
  • Stick to all timing directions so products fully cure.
  • Apply sealers/topcoats as recommended to protect finishes.
  • Expect some odor during application that will dissipate as products cure.
  • Save some epoxy resin and grout for future repairs if needed.

With the right supplies and careful technique, installing an epoxy countertop and backsplash is very achievable as a DIY project. The end result is a custom, seamless look that adds style and functionality. Be sure to do any cutting or prep work ahead of time for best results. Follow all manufacturer’s instructions closely. And take your time, especially when pouring the epoxy, to avoid mistakes.
