Priming and painting the countertop

Step 1: Prep and Paint Veins

Start by preparing your countertop surface by priming it. Choose the paint color for your veins.

Painting veins on the countertop

Paint the veins onto the countertop, creating a pattern that suits your style.

Softening the look

Once painted, use a water spray bottle to lightly mist each vein and then use a brush to soften each one up, achieving a natural look. Do one vein at a time.

White highlight paint

Step 2: White Highlight Paint

Take the white highlight paint and sponge it onto the painted veins. This step is crucial for blending everything together and creating a realistic marble appearance. Be strategic with the application, focusing on the lines you've painted.

Mixing the epoxy resin

Step 3: Mix and Apply Epoxy Resin

Now, it's time to mix the epoxy resin with the epoxy activator. Ensure a thorough mix to activate the resin properly. Spread the mixture evenly across your countertop surface.

Spreading out the epoxy

Use a foam roller to lightly spread the epoxy, ensuring complete coverage.

Removing bubbles with a heat gun

Step 4: Remove Bubbles with Heat Gun

After applying the epoxy, use a heat gun to eliminate any bubbles that may have surfaced during the process. Keep the heat gun at a safe distance and move it evenly across the countertop to achieve a smooth finish.

Removing the painter's tape

Step 5: Remove Tape

Within 40 minutes of pouring the epoxy, carefully remove the painter's tape. This timing is crucial to ensure clean lines and edges. Exercise patience during this step to avoid any smudging or unintended blending.

Installing the faucet

Step 6: Let it Dry and Install Faucet

Allow the epoxy to dry completely. Once dry, install a new faucet to give your countertop a refreshed and polished look. The drying time may vary, so follow the kit instructions for the best results.

    I did it on an outdoor deck about 5 years ago Had an old piece of granite and was going to toss it. Tried the epoxy kit and it worked great and lasted.

    I'm real curious about this product myself. I don't remember where it came up but within the past couple of days there was a conversation in a Facebook group about refinishing countertops. And it was about 50/50 of having positive outcomes with this product versus appliance paint. So now I am still in a quandary about what to do on my own.
