Fix formica on countertop

You have another option that is a long shot, but cheaper than replacing the countertop. This sounds convoluted but try it, it should work. You'll need two people.

In the exact spot the bulge is, duct tape a coat hanger to the lam like a handle. You're going to pull up on the lam while a person is under the cabinet countertop drilling a nice size hole, like a 3/8" or 1/2" hole. You're pulling up the lam so the person under it doesn't poke through the lam. The driller needs to be "very" ginger about it.

Now, once the hole is drilled through the substrate, take a bottle of Gorilla glue (while pulling up on the lam again) and load as much Gorilla juice in the bulge as you can--- try to spread it out some by pressing down on the bulge in between squirts. Once you're sure you've got some glue loaded in between the lam and the substrate, remove the duct taped coat hanger and set something flat and heavy on that spot-- like a big ol pot of water (cool water) for several hours. Note that the Gorilla snot will foam up and ooze out of the hole you drilled at least some, so place some paper towels under the hole.

This is a lot of work but should do the trick to at least carry you over until you can replace it all.

Bathroom sealant.

Would like to redo my bathroom countertop. Would the epoxy paint with the color chips you use on garage floors work on it?

Let us know what works!

I used Giani granite paint. Not a lot of work, easy to apply. I love my counters. You could also use craft paint for the faux granite, and several coats of polyurethane

Thank you Shoshana and Linda Sikut. I always try to provide good instructions. Giving a vague reply doesn't solve the problem. I also have done this in the past and it did work.
