Graffitex is an exceedingly chemical resistant coating specifically formulated to protect building surfaces against the detrimental effects of permanent graffiti marking.
Use on: Concrete, stone, brick, wood, paint and various coatings Use where: Internal/External Type of job: Surfaces susceptible to graffiti, including walls, floors, facades, fences, public buildings and sculptures
Approximate coverage: 5L 25 - 40m2 subject to porosity Cure time: Initial cure – 2 hours @ 20oC Withstands rain within 4 hours, recoat after 5 hours Full chemical cure – 2 days @ 20oC Special features: Resistant to abrasion, unaffected by the use of solvents such as acetone when removing stubborn paint, and offers excellent resistance to acids, alkalis and UV light, water vapour permeable, retaining breathability of the building materials.
The surface must be clean, dry and free of oil or grease.
Glossy and satin surfaces should be slightly abraded to provide a surface key.
Having fully prepared the substrate, stir the individual components before mixing together. Add Part 'B' to Part 'A' and thoroughly mix for at least 3 minutes. For best results use a heavy duty slow speed drill with a mixing paddle. Allow the mixture to settle for 5 minutes or until foaming has cleared.
Ensure thorough mixing as an unmixed product will result in a poor or non-cure situation.
Apply undiluted by brush, short nap roller or spray. For airless spray use 011-015 nozzle and 150-200 bars pressure.
One coat is normally sufficient but porous substrates may require a second coat, which should be applied after a minimum of 5 hours drying time.
