One of the most challenging chores for a maintenance team is graffiti removal. Applying a coat of KILZ and some paint might not cut it for the cleanup. Solutions depend on the surface. Following are some tricks:
On Aluminum—Signage or Siding. Rub a bit of the cleaning product Goof Off over the paint to determine if it’s latex or oil-based paint. Goof Off will remove latex paint. For oil-based paint, use the product STRIP X, first testing the surface to see if discoloration or other damage to the underlying material occurs. For other metals, try using a carburetor cleaner. If that fails, try a product named OOPS paint remover.
On Brick or Concrete. Extra-strength paint remover is needed here, as well as a wire brush and a lot of elbow grease. Allow the spot to dry, and remember that this process might need to be repeated several times before the area is ready to be repainted.
On Wood. Removing paint from wood can be as simple as using a coat of KILZ and a coat of paint. If you’re working with a varnished or stained surface, it can be a little trickier. For that, use STRIP X.
On Glass and Plexiglas. Carburetor cleaner comes in handy here, too. Apply it with a cloth rag, cleaning in a circular motion.
On Stucco. Option one is to apply an extra-strength paint remover and seal off the area with KILZ, then repaint with stucco paint. Option two might be more fun and is a better bet for larger areas: Rent a sandblaster.
