Powdercoated steel
Products that are powder-coated can be touch-up painted with alkyd paint.
GRC
Can be cleaned with high-pressure flushing, low water pressure, large distance between nozzle and stone and small flushing angle selected (max. 30º). If the outermost layer of concrete is worn away, the coating will become even more susceptible to impurities in the future. Therefore, cleaning with a brush and water is preferable to the hard abrasion that repeated high-pressure washing entails.
There are also cleaning agents for concrete that has been attacked by dirt and algae and then the concrete can be impregnated, which can also be done when the product is new.
Both normal concrete and fiber concrete are sensitive to hard edge impacts. A concrete product that has been damaged can be repaired with polyester filler, for example the Plastic Padding brand.
Coloured concrete
Products made of coloured concrete are washed with a pressure sprayer at low pressure. Damaged products can be repaired with a repair kit that is available to order.
