I want to preserve the look and finish of the chipping paint on my antique tin tiles. Basically, I want to use them for creating a backsplash in my kitchen (behind stove and sink areas as well as the walls) and want the chippy paint look which is currently on the tiles, but need the surface to be sealed and protected. Can you advise what I should use? Thank you....
Would putting them behind a sheet of glass be an option?– spuckNov 23, 2022 at 17:21
For a DIYer I would get a water based polyurethane clear at your local big box home improvement store and roll or brush it on. Water based is easy clean up. Your choice of sheen. do 3 medium coats.
Any sort of "clear" finish, be it lacquer, polyurethane, epoxy or other should do quite nicely to seal in the paint and patina.
Depending on the amount of tile you have to cover and your painting skills, I'd suggest spraying instead of brushing or rolling. Spraying (even with "rattle cans" of spray paint) make it easy to get a nice, smooth, even finish on the textured tin panels, spraying from all sides to ensure all angles of the texturing get covered, while eliminating the possibility of brush marks.
Obviously, you can't spray epoxy, and you may or may not be able to get poly in a spray can, but you can purchase inexpensive spray equipment that'll run it, or rent equipment.
If the tiles aren't already installed, I'd suggest that you individually coat them outdoors where you don't have to worry about overspray or smells, then install them with their final coating.
I congratulate you for saving these old tiles and reusing them! I think leaving them partially painted and patinaed will look fantastic.
