DURASID® sidings are low-maintenance. Sanding, painting or oiling are no longer needed. The closed surface structure means that the panels do not absorb moisture, virtually eliminating algal growth and moss formation. Superficial dirt from dust, exhaust gases, air pollution, etc. can be cleaned using a sponge, soft brush or high-pressure hose (max. 80 bar and with the nozzle at least 50 cm away). The water must be clean or mixed with a mild household detergent. Aggressive substances or solvents must never be used. Grease and oil stains can be removed using a household degreasing agent.
