Graffiti > GRAFTEX




Paintings, signs and messages on walls are not a recent phenomenon. These more or less prestigious activities can be found as far back as the appearance of prehistoric man. This manifestation of the artistic spirit has sadly found its way onto our public works and property with messages as diverse as they are unsightly.

Until recently, graffiti was found almost exclusively in very specific locations, such as, universities, industrial sites and underpasses. Such graffiti becomes more prevalent in times of political or social uprising.

Today, this phenomenon is quickly getting out of hand - to the point that no potential canvas is spared.

Be it on private or public buildings, prestigious dwelling or simple cottage, or even an historical monument, this form of vandalism is unacceptable. And today, it sees us deploying even greater efforts in cleaning and restoring our walls and facades in a bid to beautify our buildings and, of course, our cities.

No in-depth social analysis is needed to see that the proliferation of these acts of vandalism are largely due to the availability of various mediums used such as spray paint, markers, etc…

Stains and graffiti are most often comprised of paint or marker ink. Such offending materials are compositions of dyes or pigments and organic solvents with a binding agent.

Applied to non-porous materials such as glass and aluminum siding, these products form a film that hardens after evaporation of the solvents and is easily removed by simply dissolving the bonding agent with the appropriate solvent.

The offending materials have deeper penetration levels on materials generally used in construction such as brick, stone or cement which have a more or less rugged texture and greater porosity.

By not limiting itself to a superficial film, the deposit penetrates into the façade, thus impeding the ability of solvents to completely eliminate all traces of graffiti without additional sand blasting.

In some cases, solvents can actually worsen the situation by causing a migration of the pigments even deeper into the material. This augments the material’s porosity that leads to an even greater vulnerability to future staining and thus, a greater difficulty in bringing it back to its original state.
