SEI Industrial Chemicals Anti-Graffiti coating on 24,000 sq ft concrete sound walls

24,450 sq ft of precast concrete sound walls

The City of Sparks, a neighboring city to Reno, NV, utilized SEI Chemical’s anti-graffiti coating technology to protect 24,450FT2 of precast concrete sound walls in September, 2012. The project consisted of (4) individual walls, which would all receive an oxidizing stain treatment before being protected with (1) coat of SEI Sealer Prime followed by (1) coat of GPA-300 Graffiti Proofer®.

Josh Thompson, Civil Engineer for Atkins Global, headed up the project design. The City of Sparks requested Mr. Thompson spec the Graffiti Proofer as the anti-graffiti coating of choice for this project. As a sole-source specification could not be permitted, Mr. Thompson included the following:

Anti-Graffiti Coating shall be Seicoat Graffiti Proofer GPA-300 per NDOT QPL requirements, or approved equal. Alternate submittals will not be considered without meeting the following minimum requirements:

• Graffiti removal by wiping with a dry cloth or with light pressure washing. No release or
cleaning agents required.
• Non-sacrificial, non-yellowing and clear
• Allows expansion and contraction
• Meets the performance requirements of ASTM D6578, Level 10
• Included on Nevada Department of Transportation’s current Qualified Products List

All alternate product submissions ultimately fell short of the requirements and were not approved. The application of the Graffiti Proofer to the Vista sound walls provides the City of Sparks with the largest surface area, in Nevada, which allows graffiti to be removed without using chemicals.

2 more water tanks protected with graffiti resistant coating by SEI Industrial Chemicals

Lower 2 rungs protected with Graffiti Proofer

Water tanks are one of the premier targets for graffiti “tagging” with spray paint, stickers and markers. Due to their vast size and the remote location that most water tanks are located, it is a tempting spot for taggers to hang out and perform their “art without permission”. SEI Industrial Chemicals Graffiti Proofer coating is a clear-coat that is applied to the surface and will last for years and many removals… making it the best choice for long term protection. When the substrate does get “tagged” with graffiti, no chemicals are needed to remove most spray paints, stickers and markers. Simply use water and a rag or a low pressure wash with water only.

When Powder Coating Still Isn’t Enough Graffiti Resistance- SEI Industrial Chemicals

Parks & Rec ornamental gates

Many metal painted surfaces are “powder coated” which is typically used to create a hard finish that is tougher than conventional paint. Metal park benches, newspaper stands and painted metal gates are just a few examples. The disappointing thing about a powder coated surface is that it is usually subjected to spray paint graffiti, permanent markers and graffiti stickers (a.k.a. “Slap Tags”) and other forms of graffiti. Once “tagged”, minimal to moderate success at removing graffiti is achieved. Even more frustrating is that, by the nature of design, powder coatings can be very difficult to apply a “top coat” anti-graffiti product over.

The SEI Graffiti Proofer single component non-sacrificial graffiti resistant coating has experienced much success over a myriad of powder coated surfaces like the attached ornamental gates.

Water tank and aluminum dome protected from graffiti since 2010

Tank and Dome protected since 2010

Water tanks are prime targets for graffiti due to their locations and vast surfaces. in 2010, SEI Industrial Chemicals in California provided the Graffiti Proofer clear coat to help protect the tank and dome for years against spray paint and permanent markers. This tank was put back into service in 2010 and has been protected ever since. The anti-graffiti coating was applied to the painted concrete tank walls and the entire aluminum dome.

Plastic Fire Alarm Pull Covers protected from stickers, labels, graffiti slap tags and more

Many municipalities install plastic covers over publically displayed fire alarm pulls which solves one problem and creates another… Graffiti slap tags (labels, stickers). Traditionally, options were very limited. Either purchase a new cover each time, use chemicals to remove tags which usually results in damaging the plastic, or trying to apply a coating on the plastic to help repel stickers which usually “fogs” the plastic and makes in unusable. The Graffiti Proofer product has been successfully used by Cities to protect the plastic fire alarm covers against slap tags, graffiti spray paint and even markers… All without fogging the plastic. The Graffiti Proofer non-sacrificial coating provides long term protection for many removals.
