While using the right primer is always important, this is especially important if you’re using a lighter color like tan to cover the graffiti. Light paint colors like white or baby blue probably won’t cover the graffiti well. If you do want to repaint the wall with a light color, then you’ll probably have to remove the graffiti completely first. You can either power wash it off or use chemical removers to strip the paint.
You can find enamel paint at a standard hardware or paint store. This is a better choice if you’re covering a large area instead of just spot-treating. Glossy paint in one small spot won’t do a lot to fight graffiti in the future. Spray paint doesn’t work well for covering graffiti because it’s tough to cover a large surface with it, and the graffiti might bleed through. Latex, or water-based paint, is also not as durable and won’t work well for outdoor surfaces.
If you aren’t sure exactly what color the base paint is, get a few samples or swatches to hold up to the wall and compare. Do not cover the graffiti with a different color than the base color. Officials agree that patchwork using different colors invites more graffiti in the future. [5] X Research source
Darker colors like brown or black are usually the easiest to color-match and repaint, so these are good choices if you’re in a very graffiti-prone area.
If you don’t keep extra paint around, at least note the exact color and manufacturer of the paint so you can get more if you have to. Keep in mind that manufacturers sometimes change or discontinue color lines. This is why keeping an extra can around is better than just making note of the color.
If the surface is large and you can’t reach it all, a power or pressure washer might be a better choice. You could also just hose down the surface. This isn’t as good as a full wash, but it’s better than nothing.
Wait for the primer to dry completely before painting. For most primers this is about 3-4 hours, but check the instructions on the product that you use. If you’re using a very dark paint, like black, then you probably don’t have to use a stain-blocker. However, still prime the wall before painting.
Do not do this with 2 different colors. A section with different colors invites new graffiti.

Wait for the paint to dry and see how well the colors match before making a decision.
For large surfaces, like the side of a building, you may need a professional painting service. If you have to reach high areas, be very careful when using a ladder. Don’t stand on the top step and make sure the ladder is secure before climbing up.
Your paint may need additional drying time, depending on the type. Check the instructions on the paint you use.
