With no need to paint, stain, or treat Knotwood building products, the easy maintenance involved pales in comparison. Each surface needs regular washing to maintain the beauty of your powder-coated aluminum, not just the areas sheltered from the rain. Much like looking after a new car, a regular wash with a soft brush and mild pH-neutral detergent followed by a thorough rinsing will keep your project looking brand new for countless years to come. This process removes substances such as airborne salts, dirt, and pollutants that could hinder the powder-coated film’s long-term performance.
Where the atmosphere is deemed non-hazardous such as in rural or typical urban environments, cleaning must occur at least every 12 months. Cleanings should occur every three months in areas subject to high pollution, such as industrial, geothermal, or coastal environments. The period in between cleanings should be reduced to monthly in particularly hazardous locations such as beachfront, severe marine environments, or areas with very high industrial pollution.
Wash the surface with a mild solution of pure soap or mild non-abrasive kitchen detergent in warm water.
Application should be with a sponge, soft cloth or soft bristle nylon brush, and should be gentle to prevent shiny spots.
If cared for in this way, your Knotwood application should give many years of easy maintenance life.
