Surface Protection Questions

What is the difference between permanent and sacrificial graffiti coatings?

Graffiti Coatings – Permanent vs Sacrificial 


Firstly, A quick word on so called permanent anti graffiti coatings. 


Over the past 30 years we have seen many anti-graffiti coatings come onto the scene very often touting the latest and greatest technology in 'permanent' anti-graffiti coatings. They invariably promise to make cleaning graffiti easy in the future, and often come at great cost to building owners, having to be applied under the exact right circumstances, by contractors who have been trained or licensed to use the product. 


These sorts of permanent coatings are usually an unnecessary expense, and in many cases are specified in totally inappropriate situations. They often change the appearance of natural building surfaces with a gloss or semi-gloss finish. 


They all work to some degree at least in the initial stages, but after repetitive cleaning, continued exposure to UV sunlight, and other environmental factors such as efflorescence on buildings, they often turn cloudy, peel or delaminate in some areas.

This 'anti-graffiti' coating actually made removal even more difficult in the long term

When these sorts of coatings degrade, it can actually make it more difficult to clean graffiti in the long term. If for any reason in the future you want to remove the coating you can have a monster on your hands trying to get them off. Painting over them can be difficult, if not impossible. With our system of products, we can remove 100% of graffiti without any difficulty on virtually all building surfaces, so in most cases we would rather see no coating applied on a wall, rather than the wrong one. Problems are most likely going to occur in 2-3 years after applying a coating. This is why you need to carry a big stick and tread very carefully when considering applying any so-called permanent coating to a building surface. 


We have 3 golden rules for graffiti protection on buildings: 

1) The best coating for paint is paint. Although it’s possible to remove larger graffiti from a painted surface, it is often far quicker and easier to simply color match and paint over. Smaller graffiti can be easily removed with our Sensitive Surface Graffiti Remover or Graffiti ‘Safewipes’, without the need for specialized protective coatings. 


2) Any coating you are thinking of specifying must be proven to work as intended, and have stood the test of time without behaving badly (which ultimately would disappoint your customer). 


3) Unlike permanent coatings, if for any reason in the future you need to remove this coating from a building, you must be able to do this quickly and inexpensively without the risk of damage to the building surface.


Still, there is a genuine need for low-cost graffiti protection on certain surfaces, to ease the burden on maintenance by speeding up removals. This means protecting important building surfaces that were never intended to be painted over. These include historic or delicate buildings and sculptures, porous/ decorative feature walls and structures made from raw timber, split face rock, cinderblock, limestone and brick.

For these situations we recommend our World’s Best Graffiti Coating (WBGC) specifically designed for the protection of natural building surfaces against graffiti, pollution and grime. This amazing product is a virtually invisible and long lasting anti-graffiti coating guaranteed to work perfectly in conjunction with the World’s Best Graffiti Removers. 


Unlike permanent coatings, if you ever have to remove our coating for any reason you can remove it with boiling hot water at pressure (ie: a hot water pressure washer) or ‘chemically’ using our Bare Brick, Stone & Masonry Graffiti Remover and a cold water pressure washer. 


World’s Best Graffiti Coating is totally matte in finish and always leaves building surfaces looking perfectly natural, the way they were intended to look. In the event of graffiti occurring after you have applied WBGC, you can easily remove the graffiti either with hot water or using our removers WBGC can then be quickly and seamlessly reapplied for future protection, even if the wall is still damp. The coating has been tested on buildings around the world for over 20 years. It is a pleasure to apply and makes removing graffiti quick and easy every time. There are many opportunities to supply and apply this coating in new building construction, as well as ‘after’ removing graffiti from existing buildings. In fact, once the coating is applied to a building, removing graffiti is so easy, that many contractors will guarantee removals for a year or more.


What is the best protection for natural building surfaces such as brick stone, masonry and wood?

For maximum graffiti resistance we generally recommend World's Best Graffiti Coating on vertical walls made from natural materials. 

On horizontal surfaces we recommend 4G Surface Guard FLOORS which offers excellent protection against graffiti, gum, grease and grime, but will not change the slip resistant properties of the surface. 

Concrete and stone floors are much easier to clean with your usual wet cleaning methods once 4G Surface Guard has been applied. 

For maximum graffiti resistance on walls you can first use 4G Surface Guard followed by a single coat of World's Best Graffiti Coating. This allows you to remove any subsequent graffiti with hot water alone and will preserve and protect the building surface, for many years to come.  

How do I protect painted surfaces from graffiti?

Our first golden rule of graffiti protection is - The best coating for paint is paint. 


Although it’s possible to remove larger graffiti from a painted surface, it is often far quicker and easier to simply color match and paint over. Smaller graffiti can be easily removed with our Sensitive Surface Graffiti Remover or Graffiti ‘Safewipes’, without the need for specialized protective coatings. Some inks, dyes, boot polish and especially red spray cans can occasionally stain/burn into paintwork. These types of stains can be removed with Feltpen Fadeout


For mural protection use Muralshield and Worlds Best Graffiti Coating.


How should I protect and preserve murals?

We have proudly partnered with SPARC (Social and public Art Resource Center) based in Venice, CA in the development of MuralShield designed for the protection and conservation of fine art acrylic murals. 


SPARC is responsible for the preservation and maintenance of many large and important murals and have been advising artists, cities, and public planners around the country since 1976.


The method we use is to first apply MuralShield which consolidates the paint layers and enhances the artwork protecting it against weather and UV sunlight. For murals susceptible to graffiti vandalism our World's Best Graffiti Coating is then applied over the top of the MuralShield


This allows you to clean the mural safely using our removal products as well as giving the artist the ongoing ability to access the original artwork and make changes or touch ups as needed. 


The final outcome will be a highly maintainable, durable and vibrant mural for many years to come.

How do I protect horizontal surfaces from graffiti, grease, grunge and grime?

We recommend our 4G Surface Guard for the preservation and maintenance of natural surfaces such as concrete tile and stone. It is specifically designed for any mineral surface and optimized for both FLOORS ( with maximum abrasive resistance) and WALLS ( maximum graffiti resistance). 


The 4G stands for GRAFFITI, GREASE, GRIME, AND GUM resistance, and the end result is a long lasting, invisible impregnation that is hydrophobic and oleo phobic as well as weather and UV resistant. 


4G Surface Guard
will not change the appearance or slip resistant qualities of your floor. 4G Surface Guard is Ideal for use on high value and / or high traffic locations where minimizing maintenance costs and maximizing presentation is a priority. 


Water based and low odor makes it suitable for indoor or outdoor use. 


Our main rule of thumb before application is that if your floor or wall surface looks wet with water on it, then it will accept 4G Surface Guard.


What is the difference between World's Best Graffiti Coating and 4G Surface Guard?

Worlds Best Graffiti Coating is a 'film forming' SACRIFICIAL product that provides durable long lasting graffiti protection. It is a flexible paraffin wax emulsion that allows building surfaces to breathe. It is generally totally matte in finish and virtually invisible. Because it is film forming, it offers the best type of graffiti protection making it very quick and easy to remove any subsequent graffiti. 


When using Worlds Best Graffiti Coating, the surface must be re-protected following graffiti removal which can be done immediately to a damp (not wet) surface.Worlds Best Graffiti Coating is not generally specified on horizontal surfaces as it does not have enough abrasion resistance to withstand foot and wheel traffic. 


Correctly applied and depending on conditions, life expectancy is approximately 5-7 years. 


4G SURFACE GUARD is an impregnation rather than a a film forming sealant. It leaves the substrate fully vapor permeable. Once cured, 4G SURFACE GUARD is invisible to the human eye and does not change the surface friction making it more suitable for HORIZONTAL surfaces . 


Correctly applied and depending on conditions, life expectancy is approximately 10 years. 


For maximum graffiti resistance on walls you can first use 4G Surface Guard followed by a single coat of World's Best Graffiti Coating. This allows you to remove any subsequent graffiti with hot water alone and will preserve and protect the building surface, for many years to come.


Can I apply the World's Best Graffiti Coating over walls that are already treated with a protective or waterproofing system?

Yes - In most cases our coating will adhere to almost any pre-coated surface. It will not enhance the appearance,nor will the wall ‘breathe’ any better once its applied. 


Many of these pre treated walls are concrete, pre-cast or in situ constructed. Porous stonework may often becoated or impregnated with a sealant to protect them from rain thus preventing mildew and moldgrowth. 


If, whilst applying World's Best Graffiti Coating you find that the surface underneath is causing our coating to ‘bead’ or even repel ‘like water off a duck’s back’, follow the technique described below. 


Apply a light coat first, and when it begins to dry, brush the newly coated surface with a soft broom orwide brush to spread it out evenly. Once this is done you will find the next coat, and any subsequent coats, can be applied more thickly without further brushing required.Once World's Best Graffiti Coating is applied, any subsequent removals will be made easy. 


The types of coatings / sealers we have encountered before applying World's Best Graffiti Coating are siloxanes, polyurethanes, epoxy and hard enamels. 


NOTE: If the coating underneath is beginning to fail, it may give the impression that it is our coating thathas failed. Fortunately you can always remove World's Best Graffiti Coating if needed. 


For most porous surfaces, 4G Surface Guard can be applied first as an impregnating sealer, followed by one coat of World's Best Graffiti Coating. This method offers superior protection and allows you to remove any graffiti with hot water alone.
