Graffitiguard™ Appearance Retention Coating

From: £9.00

Graffitiguard™ Appearance Retention Coating is a graffiti resistant formula for coating porous silicate substrates such as  such as stone, concrete, terracotta and clay.  Once applied the protective layer 100 nm thick bonds with the inner pores of the substrate to leave a smooth, anti-stain, non-discolouring surface layer.

Graffitiguard™ offers protection against:

  • Repeated graffiti vandalism – offering 10-15 cycles of colour removal before reapplication
  • 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

N.B. All 1 litre bottles are shipped with a tamper evident screw tops. Trigger sprays are available to purchase on the site if needed.


Graffitiguard™  Appearance Retention Coating is an anti-graffiti coating that ensures appearance retention against the strongest elements.

The Graffitiguard™  Appearance Retention Coating is a permanent protective graffiti removal layer that prevents paint particles from penetrating the porous structure of mineral surfaces where they could become permanently embedded. This protective layer is dirt repellent and oil repellent: the sealant repels water ingress, dirt, moss, lichen and fungus from adhering to absorbent substrates such as stone, concrete, terracotta and brick and has a functional lifespan of over ten years.*

The Graffitiguard™ Appearance Retention Coating creates a nanoscale, breathable 3D coating on the substrate that permanently repels dirt and water from any porous mineral structure. The molecular fusion of the active ingredient to the surface also guarantees permanent protection against weathering, mechanical and chemical abrasion. It is therefore classified as “non-sacrificial” graffiti protection, which will withstand multiple graffiti removals with the appropriate agent. The Graffitiguard™ Appearance Retention Coating has wear resistance equivalent to the substrate that it’s applied to. Re-application of the coating adjacent to existing applications is easily achieved. All coated substrates exhibit 3-fold freeze/thaw resistance (EN1338).

This non-stick nano-care product is designed for many surface applications on public buildings and circulation areas such as underpasses, bridges, schools and external cladding, as well as surfaces that are prone to high levels of dirt and contamination (particularly chewing gum) and surfaces that require appearance retention.

Graffitiguard Appearance Retention Coating is part of the ‘building protection’ range of water-repellent spray SiO2 products that preserve, protect and restore multiple building surfaces. These weather resistance coatings are often used in building repair and building preservation processes. Continuous product development using hybrid technology and innovative techniques has created the most advanced range of dirt repellent and oil repellent solutions for new and existing buildings.

*Please note that the initially strong pearling effect can diminish after a few years due to the deposit of fine dust particles. However, this in no way impairs the protection.

The liquid is applied to the surface using standard pump spray systems. If the substrate cannot instantly absorb the liquid, roller application is advised to ensure uniform wetting. The coating is will dry quickly depending on atmospheric conditions and is fully cured after 24 hours. The product can also be used after in-depth impregnation of the surface with Nanoflex® Infusion. Leave the primary treatment to air-dry for 5 days before applying Nanoflex® AG System Coat as a final coat.

Application Instructions

Nanoflex® AG.25 and AG System (Flexiguard™ and GraffitiGuard™)

1) The liquid is applied to the surface using standard pump spray systems.

2) If the substrate doesn’t instantly absorb the liquid, roller application is advised to ensure uniform wetting.

3) The coating is will dry according to conditions after approx’ 30 minutes – and can then be walked on, and is fully cured after 24 hours.

Use a clean lint free cloth for application and wear gloves
