Product Use in the Workplace

  • Schools - School buildings and facilities are particular prone to graffiti and signatures from students. What may be an innocent tagging from one student is an eyesore for parents, OFSTED, teachers, and can be offensive to other students, too.
  • Office buildings - Why risk your company's reputation from a rogue graffiti artist tagging your property with inappropriate content, when this product can minimise maintenance spend to clean surfaces and substrates that have been defaced.
  • Dwelling - Nobody wants their home to fall victim to a graffiti attack.
  • Libraries - These public facilities can be hang-out places for students, tourists or homeless people. Often, libraries are listed buildings or expensive new-builds with the latest technology inside. Don't let someone's graffiti tag deter members of the public using a surface, or causing endless paperwork with local councils to keep the building free of graffiti - when this product can protect brickwork and masonry for you, and help remove graffiti in next-to-no-time and at much lower expense.
  • Public conveniences - Toilets and wash facilities are one of the most common places you can find graffiti tags and offensive content written on internal and external surfaces. Fight back the easy way, with an anti-graffiti coating!
  • Log houses and holiday resort buildings - Not all graffiti is offensive, such as "Tim was here 2018", but it can be a major headache and expense to clean up end of season.

For use on brickwork, concrete, natural stone, reconstructed stone and blockwork and timber. Compatible with concrete surfaces treated with Silane. Allow 72 hours to lapse before overcoating surfaces treated with Silane.

Ensure surfaces to be treated are clean, free from contamination and dry. Treat all areas affected by organic growth with Hydron SS1 Sterilising Solution.


1 or 2 applications using low pressure spray. Alternatively a brush or roller may be used by applying to saturation point, taking care to avoid any sagging. One application is normally required, however, on porous substrates a second application may be required. Apply the second application in the same manner immediately after the first application, taking care not to allow the first application to dry out. Do not apply at temperatures below 5°C. Shake container well before use. Allow 72 hours to lapse before overcoating surfaces treated with Silane. On vertical surfaces, apply from the bottom up. Coverage is dependent on texture and porosity of the substrate. The figures quoted below are average coverage rates and given only as guidance:

  • Sandstone: 5m²/litre
  • Facing brickwork: 5m²/litre
  • Concrete: 5m²/litre
  • Concrete blockwork: 3m²/litre
  • Reconstructed stone: 3m²/litre
