How do I blend a counter with an added countertop?

Maybe fill the crack and paint the whole thing?

There is a product called Seam-fil that you can color match to blend and smooth the seam.

You could recoat the entire countertop with epoxy to give it a whole new look and cover the seam. Check out this company. https://www.stonecoatcountertops.com/ultimate-epoxy-countertop-kit?gclid=Cj0KCQjw9tbzBRDVARIsAMBplx8O3mRCqBiXi_S2CYfvoTajLx_EPenCjmm1KSUGLtGo_VunYbysYnoaAsmMEALw_wcB

Yes do a countertop pour!! That would work best for that problem. We used ENVIROTEX resin when we did our countertops. Totally ok around food and they use it on bar tops. I painted my kitchen countertops with stone spray and made it look granite like. Then poured envirotex resin on top of it. You might want to make a frame for the sides of the countertop because the edges are tricky to get a smooth finish. But whatever you do, cover the lower cabinets with plastic because when it gets poured, it will drip down off the sides. Follow the directions on the box and you will love the result. For a few years after we did it, people thought it was granite. Good Luck! Then you use a blow torch to get all the bubbles out. Google tutorials. It's a great product and our countertops have held up for years now. People ask me if it was real granite. I think we used 5-6 boxes of envirotex for our countertops. Totalling around $300. hope this helps. It definitely has extended our old pink laminate countertops for another 5-6 years before we can afford real granite or quartz. Good Luck!

Seams can't be eliminated, but they can be hidden with a seam filler that matches the laminated surface's color. Use a seam filler and then use a counter top paint kit and give those counters a whole new look.

Home Depot has lots to choose from:

Blending the counter you can fill the seam with two part epoxy. Then paint the whole countertop. The pattern is so off no way to make it match.

If you are good at matching paint you could make it look better using a feather. Try to extend the browns and grays in both directions. Might as well try it.

Sounds like a perfect way to do it

Epoxy mix with tint will for sure add help you with that

Lots of great suggestions, I would just go with one that safe to use with food on a countertop.

The 2 countertops do not match up in the patterns of each, so a blend is not the way to do this. A 2 part epoxy to smooth it out and then paint.
