Case Study

Cast Concrete Building, Las Vegas, Nevada

4G Surface Guard was applied for anti graffiti protection on approx. 50,000 sq. feet of a 40 ft. high cast concrete wall facing two major roads, with more planned for the future.

Evaluating Strategies for Graffiti Removal & Sustainable Protection

This case study offers a brief, behind-the-scenes look into the decision-making process and testing results for graffiti removal process and protection of a 40ft high natural finished concrete wall using 4G Surface Guard.

Various well-known coatings, graffiti removal products, and removal methods were tested, including various abrasives (such as wet sandblasting, glass beads, walnut shells, dry ice blasting). Although the results varied, all of them permanently degraded the appearance of the surface by removing substrate each time, rendering them unsustainable in the long term.

The primary goal was to attain a natural/invisible finish on the concrete and alleviate the burden of graffiti removal without leaving any signs of future damage, a goal successfully achieved through the use of World’s Best Graffiti Removers.

Invisible, Permanent Protection with 4G Surface Guard

In the images above, you can see the results achieved using our Worlds Best Graffiti Removal products. The graffiti has been completely removed without any damage or ghosting. This section of the wall was first coated with 4G Surface Guard. You can see the final finish is invisible. This is attributed to 4G Surface Guard being a permanent impregnation rather than a film-forming coating. It works by penetrating mineral surfaces, creating a hydrophobic and oleophobic surface that resists grime and graffiti.

FAQs

Why was 4G Surface Guard chosen over abrasive removal methods?

Abrasive methods such as wet sandblasting, glass beads, walnut shells, and dry ice blasting all permanently degraded the appearance of the surface by removing substrate each time, making them unsustainable long term. 4G Surface Guard protects the wall while allowing graffiti to be removed without damage.

Will 4G Surface Guard change the look of the cast concrete?

No. 4G Surface Guard is a permanent impregnation rather than a film-forming coating. It penetrates mineral surfaces to create a hydrophobic and oleophobic barrier, leaving an invisible, natural finish on the concrete.

How difficult is it to apply 4G Surface Guard to concrete?

Applying 4G Surface Guard to cured concrete is a quick and straightforward one-step process. When used with World's Best Graffiti Removal Products, any graffiti can be promptly and easily removed without causing damage to the underlying surface.
