The method you use to cover your graffiti area depends on the type of surface that is covered in graffiti. Different surfaces must be treated differently. For example, wood surfaces can be treated with some primers and a coat of regular paint.
It may take a few more layers than you expect to completely graffiti removal. You must allow the drying time between each layer you need.
When coating metal, you can try several paint removers that are available in the market. Depending on the type of paint the artist used to create the graffiti, you may need to try more than one brand. If your metal surface has finishing work, pay attention to the tape you use. Otherwise, steel wool can be very useful in removing scribbles.
For brick or cement
You can use paint remover on brick or cement surfaces, but you need to make sure it has extra strength. You will also need to use a wire brush to blend the area. After scrubbing, you need to rinse the area with a water hose.
You may have to do this task several times before deleting the scribbles. After cleaning, you may still need to paint the surface for a flawless finish.
Glued to the Paris plaster
When trying to cover your scribbles on Paris plaster, you will find that this is probably the most difficult surface to cover. The rough surface makes the paint remover difficult to use. You may need to use a sandblaster to remove the graffiti from the walls.
