|Although we have no formal maintenance brochure for our products, the following general guidelines will apply and should be followed:
As with any product used in a commercial application, an annual or semi-annual inspection of the product should be conducted. Any loose or missing hardware should be tightened or replaced immediately. If any part of the item is found to show excessive wear or is cracked or broken, the product should be taken out of service until all repairs are made.
All wood components should be inspected for excessive cracks or splits and repaired or replaced as needed. The surface of wood components should be checked for splinters and sanded as required. Discoloration of wood can be treated using a 50/50 mixture of household bleach and water. Mix the solution in a plastic bucket only. Using rubber gloves and a mild bristle brush, apply the mixture and lightly scrub leaving the mixture on the wood for 3 to 4 minutes. Rinse with clean water. Allow the wood to dry, and then recoat with a clear non-toxic, oil-based or water-based preservative.
All recycled plastic components offered by DuMor are extruded 100% polyethylene. If the surface requires cleaning only, any household cleaner such as Fantastik®, Formula 409®, or Armor All® may be sprayed on and wiped off. If the surface has been marked with graffiti, a high-pressure washer may be used to remove the graffiti. Severe scratches and carvings into the surface may be hand sanded with a fine grade of sandpaper.
All steel components have been finished with a baked-on polyester powder coating which offers long-lasting protection against acids, salts, and corrosive moisture. Because of its smooth texture, it will stay cleaner than wet-applied paint or a galvanized surface. Our powder coating forms a finish 4-6 mils thick when cured and becomes a sacrificial coating giving superior chipping resistance. If the surface requires cleaning only, any household cleaner such as Fantastik®, Formula 409®, or Armor All® may be sprayed on and wiped off. If, however, the finish is abraded to the point of exposing the steel or similarly rusted, lightly sand the surface being careful to remove all rust as well as any loose finish materials. Once this sanding is complete, clean the surface with a solvent such as paint thinner to remove any remaining contaminants which might hinder proper paint adhesion. A good grade of exterior metal primer and top coat of matching color enamel should then be applied over the prepared surface.
