How would wrapping paper sealed with polyurethane work for countertop?

Hmmm....I don't know. Countertop to prep food? I have heard of people putting poly on it in kitchens but not sure. I used ENVIROTEX resin. I think that is how you spell it. 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. In this case, if you wanted to do your wrapping paper thing...you could do that instead. Then pour envirotex resin on top of it. It will drip down the sides and make the sides not so great(happened to us) so frame the sides or put contact paper on the sides so you don't get the plastic drips on the edge. Then you use a blow torch to get all the bubbles out. Follow the envirotex directions on the box. 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. Something to thing about instead of polyurethane on a countertop. hope this helps. Good Luck!

It wouldn’t work because it’s not scrubbable and any hot pans would mar the finish.

If you want to pour a resin coating over the top, then that would work for something like a serving top or non-cooking countertop. Resin tops need to have forms or sides and require a lot of ventilation and time to pour & cure.

Whatever you use would have to be food safe which increases your cost dramatically. In all honesty, while a clever idea, I don't know how well this would hold up with all the wear and tear a kitchen gets.

I wouldn't use it for fear of food contamination since it wouldn't hold up to scrubbing. Get prices on a replacement section...I think you'd be surprised at how inexpensive some countertop materials and installation can be. Also, leftover sections of high-end countertops are often available at great prices. Make a few calls!

I doubt that it would hold up on a countertop. Many use it for floors but usually seal it six to twelve coats of poly. I would prefer using one of the countertop paint kits.
