I have a countertop that is formica and I'd like to change it to a stone line composition. I understand there is a product that is in a liquid form (like paint) that I can apply to change the formica to look like a stone surface. Does anyone know what this product is and whether it is a strong enough surface to withstand the heat/cold of a cabin through winter with no heat?

Thank you so much for your time!

Maybe something like this is up your alley. Transforming Old Formica Countertops It would hold up as well as any painted surface inside the cabin. You may also be interested in a Rust-Oleum product called Stone Creation, Google it.
