For new unpainted signal light poles, GPC will use one of its Teti removers to wipe away the graffiti. If applicable, GPC will clean cross boxes, traffic signal heads, and remove stickers. -Unpainted Wood Unpainted wood is one of the easier surfaces to clean. Tech will obtain permission from property owner to complete the work. Most wood comes clean with hot water and a wide-angle spray tip in the wand. If required simply applying a little bit of graffiti remover will always be enough to complete the removal. GPC cleans the entire wood panel, not just the graft area. Any water will be recovered. GPC's goal is to make it look like the graffiti never existed. Any disoolorations that might occur in the wood disappear over time. -Previously Painted Surfaces Most all previously painted surfaces will be cleaned as discussed in "Methods- Painted Surfaces" portion of this proposal. For painted surfaces that are semigloss, gloss, oil based, powder coated, or anti-graffiti coated, they can often be cleaned with our delicate surface graffiti remover. Spraying the remover onto the surface followed by light scrub will remove the graffiti usually without damaging the paint. Since all GPC removers are water soluble, a wipe with a wet rag removes the entire residue and restores the surface to new. -Plnsdc/metsi sign All graffiti on signs will have graffiti removed using graffiti removers. ff it is necessary to replace the sign, the type of sign and location will be forwarded to the sign shop. The back side of metal signs may be painted with Hard Hat Grey Primer, Silver Spray Paint, or Cape Cod Grey. The entire back side of the sign will be painted. GPC also possesses special graffiti movers designed exclusively for plastic and polycarbonates -ConcreteNidewalk Unpainted concrete and sidewalks have smooth finishes compared to split face block. Tech will obtain permission from property owner to complete the work. If the tech is too aggressive with the removal on this surface, the surface will start to look like split face stone block and subsequent removals will become more and more difficult. GPC noticed many walls in this condition in the City where not only was the block wall finish damaged, but subsequent removals were becoming less and less effective as the block became too porous after all the water blasting. GPC has the solution to this problem. GPC standard process is started. First, washing the graffiti with hot water starts the graffiti removal process. Next, any remaining graffiti gets a thin coat of graffiti remover designed for non-porous stone. The graffiti is rinsed again with hot water. If any graffiti remains, a second application of graffiti remover will be applied. These processes will not cause any damage to the surface . If any graffiti or shadows still remain, then GPC will use baking soda wet blasting. GPC always cleans the entire concrete block, not just the area affected by graffiti. Cleaned areas are "blended" in a manner similar to "feathering" in painting. All water used will be recovered. 25C-43
