Graffitiguard™

Welcome to the Graffitiguard™ page

Graffitiguard™ is a stain- and graffiti-resistant formula specifically designed to coat porous silicate substrates such as sandstone, concrete, terracotta and clay. Once applied, a protective layer less than 100-nm thick (80,000 times thinner than a human hair) bonds with inner pores of the substrate to leave a smooth, anti-stain, non-discolouring surface layer.

The coating is breathable, optically clear, UV stable, chemically inert and extremely durable, having both hydrophobic and oleophobic capabilities. It will not peel or flake and is unaffected by extremes of temperatures from –20°C to +350°C.

Graffitiguard™ offers protection against:

  • Efflorescence
  • Embedded and ingrained soiling, mould or fungal growth
  • Chemical attack
  • Corrosion by salt
  • Repeated graffiti vandalism – offering 10–15 cycles of colour removal before re-application
  • Chemical attack including acrylic paint damage – allowing easy removal of solvent-based graffiti and solvent-free graffiti
  • Damage from fat, grease and oil products
  • Colour seepage into substrate
  • Abrasion and frost damage.

GRAFFITI REMOVAL

Where the substrate is suitable, graffiti is removed by high pressure cleaner (max. 50–60 bar) and water at +90°C. On more sensitive surfaces or where hot water is unavailable, a commercial-quality, graffiti-removal paste can be used, followed by a final washdown with water.

APPLICATIONS

  • Sandstone
  • Terracotta
  • Brick or clay
  • Slate
  • Roof tiles
  • Building façades
  • Bridges and tunnels
  • Passenger facilities
  • Precast concrete blocks, stonework, bricks and pavings
  • Stone panel floor and wall coverings

STRUCTURE

Solvent-free Graffitiguard™ is made up of silicon dioxide molecules whose surface energy is modified by anti-bonding molecules. On application to the porous substrate, silicon dioxide molecules from the coating and the substrate start to bond together releasing the anti-bonding molecules. These molecules migrate to the surface creating an ultra-smooth, protective outer layer, and changing the status of the porous substrate from high to low energy. This low-energy status is fundamental to the repellent qualities offered by treated surfaces.

 

BENEFITS

The existing surface quality is preserved, becoming highly water and grease repellent, and resistant to ingrained soiling, mould, fungal growth and colour seepage. Paint and other contaminants are unable to adhere to the surface. Cleaning becomes much easier and less frequent – typically required 50–70% less often – and withstands high-pressure cleaning (up to 50–60 Bar). The lifespan of the substrate is extended because of reduced cleaning cycles. The surface remains clean and will not discolour.

TREATMENT METHODS

Applied by surface spraying, brush or roller onto deep-cleaned surfaces, Graffitiguard™ can be applied almost anywhere: on site, at manufacturing premises or in a dedicated application centre. Graffitiguard™ can be applied on new surfaces during manufacture or installation, or on existing surfaces to prevent further deterioration. Hardening at 20°C, the treatment requires no additional energy or UV light during application.

As the silicon dioxide molecules (blue) in Graffitiguard™ bond seamlessly with those lining the inner pores of the substrate, the anti-bonding molecules (brown) form a highly protective, breathable surface layer. By preventing a buildup of water, dirt or oil, the growth of mould, fungi, moss and bacteria is inhibited. Colour seepage by solvent-based paints is prevented.
