I have a bathroom counter top on the sink cabinet. One corner has loose
formica. The cabinet top is plywood, which is in good condition. The
fomica is also in good shape, but it's loose from the plywood on that
corner. Aside from replacing the counter top, I'd like to fix this.

I know formica is normally glued with contact cement. I'm assuming I
need to use the same stuff to reglue it. I had a thought to buy some
large syringes made for animals, fill the syringe with contact cement
and squirt it under the loose formica. Then stack some bricks or other
weights on top of the counter and let it dry for at least 24 hours.

Is that how the pros do it?
Are there other methods?

Thanks
