Here’s what to do:
- You need to make sure your floor is clean. Use a wax remover if applying over linoleum, which can be done.
- If you want shiny pennies, you can soak them in vinegar. Make sure the coins have the patina you want even if it means going to the bank and getting rolls and rolls of pennies to search for clean coins.
- If you want a design, lay it out first on the floor so you know how it will fit together.
- Glue the coins directly to the floor, preferably in the same direction and pay attention to heads or tails (if it matters to you). Weldbond, a tile or glass glue, was used for many of the penny floors, but some used Elmer’s Glue, which seems a little on the flimsy side, and Gorilla Glue.
