INDUSTRIAL ANTI-GRAFFITI COATINGS

Graffiti paint removers

The process of graffiti removal is often a laborious and costly one.
The problem of graffiti removal is not easy to solve due to the fact that the longer the paint has lingered on the surface the harder it is to remove. This is caused by the paint particles penetrating into the structure of the material which they have been applied onto as well as the paint preservation by sunshine and changeable temperature.
If inappropriate cleaning means are used, they may damage the surface and hamper its cleaning in the future.

New cleaning technology

Thanks to a new KT Removers product line, graffiti removal is more time-efficient, less complicated and most importantly, does not damage original surfaces.
Due to the chemical composition of graffiti paints, our removers either contain organic solvents or they are alkaline water-based solutions which decompose dyes thus enabling hydrodynamic removal of the paint remains by means of a brush, cloth or sponge.

Anti-graffiti Professional KT Removers are also efficient on various substrates without prior application of anti-graffiti coating. When removing paint from unprotected absorbent surfaces, if a liquid cleaner is used, it may result in further penetration of the paint into the substrate and the increased stain of solved paint on the surface. It is recommended to use gel rather than liquid solvents in such cases, to bind the paint, delay solvent vaporisation and prolong chemical reaction time.

KT Removers are available in the form of both liquid (for non-absorbent surfaces) and gel (for absorbent and non-absorbent surfaces). Removers can also be used on surfaces where anti-graffiti coatings have been applied. The removers presented below are organised starting from  their low power of impact on the most sensitive surfaces to the most powerful ones for use on solvent-resistant surfaces.

Types of the Anti-graffiti Professional KT Removers

KT 01: liquid preparation for use on delicate, smooth, non-absorbent surfaces sensitive to strong solvents. It does not cause the matte effect on the cleaned surface. T is the weakest of all the Anti-graffiti Professional KT Removers line. Applicable on multi-chamber/solid  polycarbonate, Plexiglas, laminates, plastics, foils, varnish coatings. Suitable for lifts, toilets, telephone booths, bus shelters, acoustic screens, schools, railway carriages, trams, buses, cars, road signs, advertising foils and boards as well as durable poly-urethane anti-graffiti coatings.

KT 01+: gel preparation for use on delicate, smooth and porous non-absorbent surfaces sensitive to strong solvents. It does not cause the matte effect on the cleaned surface. It is the weakest of all the Anti-graffiti Professional KT Removers line. Applicable on multi-chamber/solid  polycarbonate, Plexiglas, laminates, plastics, foils, varnish coatings. Suitable for lifts, toilets, telephone booths, bus shelters, acoustic screens, schools, railway carriages, trams, buses, cars, road signs, advertising foils and boards as well as durable poly-urethane anti-graffiti coatings.

KT 02: liquid preparation for use on smooth non-absorbent surfaces. It is the third weakest of all the Anti-graffiti Professional KT Removers line. Applicable on laminates, plastics, foils, metals, aluminium, glass, industrially-painted surfaces, ceramics. May be tentatively used on surfaces sensitive to aggressive solvents, such as multi-chamber/solid polycarbonate, after a test trial. Suitable for lifts, toilets, telephone booths, bus shelters, acoustic screens, schools, railway carriages, trams, buses, road signs, advertising foils and boards as well as durable poly-urethane anti-graffiti coatings.

KT 02+: gel preparation for use on smooth and porous non-absorbent surfaces. It is the third weakest of all the Anti-graffiti Professional KT Removers line. Applicable on laminates, plastics, foils, metals, aluminium, glass, wood, industrially-painted surfaces, ceramics. May be tentatively used on surfaces sensitive to aggressive solvents, such as multi-chamber/solid polycarbonate, after a test trial. Suitable for lifts, toilets, telephone booths, bus shelters, acoustic screens, schools, on, railway carriages, trams, buses, road signs, advertising foils and boards as well as durable poly-urethane anti-graffiti coatings.

KT 03: liquid preparation for use on smooth non-absorbent surfaces. It is the fourth in terms of its strength of all the Anti-graffiti Professional KT Removers line. Applicable on laminates, plastics, foils, metals, aluminium, glass, industrially-painted surfaces, ceramics. May be tentatively used on surfaces sensitive to aggressive solvents, such as multi-chamber/solid polycarbonate, after a test trial. Suitable for lifts, toilets, telephone booths, bus shelters, acoustic screens, schools, railway carriages, trams, buses, road signs, advertising foils and boards as well as durable poly-urethane anti-graffiti coatings.

KT 04: liquid preparation for use on smooth non-absorbent surfaces resistant to aggressive solvents. It is the fifth in terms of its strength of all the Anti-graffiti Professional KT Removers line. Applicable on metals, glazed brick, glass, ceramics and durable poly-urethane anti-graffiti coatings in short-term exposure. May be cautiously used on plastics.

KT 04+: gel preparation for use on porous absorbent surfaces resistant to aggressive solvents. It is the fifth in terms of its strength of all the Anti-graffiti Professional KT Removers line. Applicable on brick, glazed brick, cement-bound substrates, plaster, concrete, sandstone, granite, travertine.

Removal of graffiti paint from a block of flats

 

Chemical-based graffiti removal from permanent coating KTX 15

 

Successful graffiti removal from an unprotected surface depends on:

  • Chemical composition of the graffiti paint,
  • Graffiti exposure period on the given substrate,
  • Outdoor temperature during paint application,
  • Substrate sensitivity to solvents,
  • Substrate absorptiveness.

It is the easiest to remove graffiti from smooth and solvent-resistant surfaces (glass, metals, ceramics etc.) It is also usually possible to remove graffiti quite easily from solid, slightly absorbent mineral substrates, clinker or granite with use of suitable cleaning media or/and hydrodynamic devices.

Graffiti paint can also be removed from porous building materials (sandstone, plaster or concrete): in such cases full removal of graffiti paint, despite using chemical and mechanical cleaning methods, may be impossible due to pigments’ penetration of the substrate as deep as 10 mm. Cleaning may only affect the surface of the substrate; the particles of paint which have penetrated deeper into the substrate may remain visible as a so called “shadow” effect. Mechanical removal of this residue may cause visible changes to the surface texture. It can also be risky to remove graffiti from substrates which are not solvent-resistant, like e.g. multi-chamber polycarbonate.
