Anti-graffiti protection

Anti-graffiti-protection coatings (TRB)

Anti-graffiti-protection coatings consist of several components (sometimes these coatings only consist of one component that is usually a dissolved or dispersed agent) that cover or penetrate the concerning surfaces.

Anti-graffiti-protection coatings make it easier to remove graffiti. There is no protection coating which would be suitable for all possible undergrounds. In order to ensure a qualified order execution, a certified enterprise should accomplish an individual examination before.

Characteristics of Anti-Graffiti-protection coatings

Temporary protection coatings

Advantages:	Disadvantages:
reversible less expensive than permanent systems easily applyable protection coating hardly visible some of them can easily be cleaned with water very good watersteam permeability depending on the system and surface: protection lasts several years	limited effectiveness to a certain extent maintenance is required

Semi-permanent protection coatings

Advantages:	Disadvantages:
One-layer-systems: less expensive than permanent systems protection coating hardly visible Two-layer-systems: selection of sacrifical layers is possible Using this system penetration of graffiti through the coating becomes more difficult permeable-to-water-steam systems possible	durability to a certain extent maintenance hardly necessary

Permanent protection coatings

Advantages:	Disadvantages:
durable adheres to many different surfaces good graffiti removal corrosion-resistant systems in different colours not permeable to carbon dioxide	irreversible not permeable to water steam senitive to moisture in the masonry in case of fire: development of cyanogen compounds possible some systems become yellow

According to our experiences the following protection varieties are not recommendable:

• Coating of natural stone using two-component-coats (e.g. polyurethane)
• Coating of thermal insulation systems (if necessary after individual case examination possible)
• Coating of dispersion paint layers (if necessary after individual case examination possible)
