Allow the panel to dry completely, which may take up to 24 hours depending on the thickness.
Once dry, sand any rough edges and apply a coat of clear sealant to protect the surface and enhance its durability.
Install the panels on your chosen wall using adhesive or nails, ensuring a seamless fit.
For a more industrial look, consider painting the panels a dark grey or even a distressed white. You can also experiment with different brick patterns and sizes for a custom look. Adding a metallic or glossy finish can provide a modern twist, while a matte sealant will maintain a more traditional, rustic appearance. If you’re looking for a more colorful option, try using colored cardboard or adding paint to the paste before it dries.
