Case Studies

7. Aged, brittle, damaged brick or concrete
Solution:
In these cases, high pressure water to clean after treatment can lead to serious damage. The EnviroPrime/EnviroPeel process will allow removal of the graffiti without using high pressure water. The white pigment on the red brick can be difficult to remove, however the EnviroPrime will help lift this pigment away from the brick surface.

In the case of the concrete surface, paint overs have not allowed the concrete to breathe and spalling has occured during the freeze/thaw process during seasonal changes.
1.
Enviro-Penetrator - Soak both surfaces with liberal amounts of Enviro-Penetrator. Allow the product to dwell for 20-30 minutes. Working the Enviro-Penetrator into the pores with a stiff brush is recommended.
2.
Enviro-Peel - Apply a liberal amount of Enviro-Peel directly over the treated surface and allow to dwell an additional 30-45 minutes depending on how heavy the graffiti is.
3.
Wash the area using low pressure water under 500 psi to remove the graffiti. The surface may be washed with a solution of our EnviroClean and water and scrubbed with a stiff brush. Rinse the surface with fresh water when completed. If shadows remain, repeat the process.
8. Graffiti on Painted Surfaces
Solution:
The white pigments on the brown siding are more difficult than other pigments due to the nature of the pigment size. In this case, the application of Enviro Graffiti Gel may be the better alternative. It will adhere to the vertical surface allowing it to dwell over the graffiti prior to removal. Testing the ease of removal with a liquid product will determine if this is necessary.
1.
Graffiti Removal Wipe - simply wipe away graffiti with a single wipe (test surface prior to removal) Neutralize surface with water when completed graffiti removal.
2.
EGR Remover for Professional Use- use a soaked rag and wipe away the graffiti. Always neutralize the surface with water when completed graffiti removal.
3.
Enviro Graffiti Gel - this gel version of the Enviro Graffiti Remover is specially formulated for vertical surfaces. Use the same procedure as you would with Enviro Graffiti Remover.
9. Graffiti on Block Wall
Solution:
In both cases, there are two options. The building may be painted or stripped. If the natural block look is desired, then coating with a RainGuard anti-graffiti coating is recommended after the graffiti is removed. The most economical solution to the painted building is to repaint the complete building.
1.
Enviro-Penetrator™/EnviroPeel™ - natural block is very porous. The most effective way to remove graffiti is to apply the Enviro-Penetrator liberally working it in to the pores using a stiff brush. Allow the Enviro-Penetrator to dwell a minimum of 15 minutes prior to the application of Enviro-Peel.
2.
Apply Enviro-Peel™ over the treated surface and allow to dwell a minimum of 30 minutes. Pressure wash with water at 1500 to 1800 psi. Be careful not to hold the pressure washer directly on the grout lines for extended period of time.
