Anti-Graffiti Coating - Anyone used or heard good things?

[Bennyhonda]

Anyone ever used an anti-graffiti coating with any success? Any recommendations?

Thanks,

Should discuss what is meant by the term 'Anti-Graffiti coating'. Sometimes the term is used in reference to a sacraficial non stick coating that can deter adhesion of graffiti or can be easily removed with any graffiti that does stick to a surface--aka a wax or oil. But this is useless on its own since the surface underneith is often damaged from the chems used to remove the graffiti.
Now a true anti graffiti coating really is opposite and is a permenant base coating that is applied to a surface that will withstand extreme abuse of chems used to remove grafitti. There is one main product that achieves this. Anti graffiti coating or paint is none other then a 2 part catalyzed polyurethane same as used over deco concrete epoxy or garage floors in the floor coating world, or in some car finishes, etc..
2 part poly and anti graffiti are interchangeable and synonymous terms.
Mechanical abrasion is pretty much the only thing to damage it so you don't agressive clean with scour pads or grit but rather you use cleaners strong enough to clean and disolve the acrylics, enamels, lacquers found in spray paint. In practice, a little brushing is used to help break bond between the urethane and the graffiti or between the graffiti and a sacraficial wax type top coating which can go over the urethane.

Pretty much what he said. Here's a short freebie course from AEC.
AEC Daily: Anti-Graffiti Coatings and Graffiti Removal Technology
After your done you can give yourself an eyegasm with all the continuing ed courses they have. Great resource! Enjoy

btw..similar to epoxy you will want to try and mix up only exactly what you need for each coat as it will cure all on it's own in bottom of container by reactive means rather than evaporation before your ready for additional coats. Makes for a nice frisbie collection as it is hard to be exact.

I think the Textured Coatings of America (LA, CA) has some really good products along this line.

Sacrificial- which is a high temperature wax, works okay with hot water pressure washing, but top coat has to be reapplied afterwards. not great for hot climates because the product gets tacky, or someone at a local bus stop may get a free souvenir sample on their clothing. colorless and odorless, and does not darken colors. downside is the wax attract pollutants and smoke particles in warm areas and airports.

Permaguard- another two component coating that offers up to 4 or more washings before the top coat has to be re-applied. Usually a special solvent has to be used in conjunction with the cleaning.

these work pretty good and carry a guarantee.

There are block sealers based on thin silicone products that are applied once, and carry a 10-year guarantee. works best on dry masonry or concrete. any percolation of moisture, alkali, efforvescence, or bonding problems that affect painted surfaces, will also affect this and the above noted products. removal also requires a special solvent. downside- one can never paint the wall or substrate because paint won't bond proportionately
