Comment éliminer les graffitis des surfaces peintes et enduites

If it’s smaller graffiti on a painted surface or if it’s on things that you can’t paint out, like ‘For Sale’ signs, street signs, glass, playground equipment, cars, caravans, equipment, powder-coated surfaces, etc., then use these two products: Sensitive Surface Graffiti Remover (or Graffiti Safewipes) and Feltpen Fadeout


If it’s larger graffiti on painted surfaces like walls and fences, although it may be possible to remove the graffiti using our products, it is usually far quicker and easier to match the color and paint it over. The trick to doing this well is having the ability to color match, and use tools that can be easily cleaned out on the job, such as High Volume Low-Pressure Spray Guns (HVLP), mini rollers, and paint pads.


You only need to color match any given wall once, and from then on you can keep that color for future paint overs, if needed. Very often, building owners or managers have the exact color you need to spray their wall (stored under a kitchen sink or in their garage) so don’t be shy to ask given the opportunity. Standard graffiti block-out colors you choose might include Navajo White, Sound Wall Tan, Cinderblock Gray, Concrete Grey, Old Wood Fence, New Wood Fence, Mission Brown, Forest Green, Electrical Box Green, Brick Red, City Beige, Country White, Fire Hydrant Yellow etc.

Some larger wall areas of ‘sound’ acrylic paint ( see example above), can sometimes have quite large graffiti tags, removed without any damage to the underlying paint. To do this use the method described below;


I

Start up your pressure cleaner, making sure that it is running low pressure on warm to cold temperatures, and thoroughly saturate the graffiti area. 


II 

Using a soft nylon broom and a rectangular bucket containing Bare Brick, Stone and Masonry Remover, quickly apply and agitate about 10 square feet of the graffiti until approximately half disappears (the graffiti is dissolving and running). 


III

Using low pressure, quickly rinse this treated area, and thoroughly wet down ahead to repeat the same on the next section. Approximately 95% of the spray can graffiti should be gone. If you find that it is affecting the underlying paint, you will have to shorten your initial application time. The reason you stop at approximately half dissolved is that the rinsing tends to remove another 50% more than you have. 


IV

Carefully spot clean any uncleaned areas using Sensitive Surface Graffiti Remover. If the dissolved graffiti has stained the wall, a dilute application of Feltpen Fadeout will return it to its former glory. With this technique never use hot water (it could blister the underlying paint)!
