Knotwood does not require restaining, re-coating or resealing. However, to maintain the look of your powder coated aluminium , all surfaces require washing all over. Like any application, a regular wash will keep your investment looking it’s best. Washing with a soft brush and mild pH neutral detergent followed by thorough rinsing with fresh water will ensure that substances such as airborne salts, dirt and pollutants detrimental to the long term performance of the powder coated film are removed.
Where the atmosphere is deemed to be non-hazardous such as rural or normal urban environments, cleaning must take place at least every 12 months. In areas subject to high pollution such as industrial areas, geothermal environments or coastal environments then the cleaning frequency should be increased. In particularly hazardous locations such as beach fronts, marine environments or areas of high industrial pollution the period between cleaning should be reduced to monthly.
