hered and 6 weathered fibre cement slabs of 20 cm x 30 cm dimensions (1 year outdoor weathered), decorated with a light colour and an anti-graffiti coating. These specimens were inspected for visible defects. It was agreed with the customer to use the graffiti remover Rasant 031 in combination with the water-based cleaner Arrow-Plan. Specimens were stored for 7 days at room climatic conditions before the „basic test“ and the „stress test“ were conducted. Testing: Durability test Testing of durability of applied anti-graffiti systems against the graffiti removers Rasant 031 and Arrow-Plan: - measurement of the initial values of gloss and surface texture on three defined areas of each specimen - deposition of the graffiti remover over a residence time of 3 hours - removal of the graffiti remover according to the technical application instructions - storage of the fibre cement slabs for 2 hours at standard climatic conditions after cleaning - measurement of gloss and surface textu

From these characteristic numbers for the “cleaning power” (KZ Farbe) of each colorant, the functionality parameter C can be calculated. For the basic test, the equation for the parameter C reads: 10 (5 K

Durability test Table 1 lists the results of the durability test. No changes in gloss at 85 °geometry ( GE // 85°) were found. No changes in the roughness parameters such as Ra (arithmetic mean of the profile) and Rz (maximum height of the profile) were detected (total distance: 12,5 mm, single distance: 2,5 mm). It can be summarised that the combination of the graffiti remover Rasant 031 combined with the water-based cleaner Arrow-Plan has no negative impact on the glos

The surface of the anti-graffiti coating became only slightly rougher during the stress test, independently of the colorant applied. This finding agrees well with the changes in gloss, which were only up to 3 gloss units (GE) maximum at 85 ° geometry.
