Poorly performed scales treatments may be the result of a number of factors. One may be simply going through the motions without understanding the purpose and desired results of the process. Another is the lack of proper pre-treatment of the surface to ensure good adhesion, as well as the lack of an appropriate primer to bridge the gap between the scales and the substrate. Additionally, if proper surface conditions are not maintained, slip-resistant features may be compromised, due to film and particulate contaminants mixing with the pre-treatment solution.
Providing a safe environment is a primary concern of OSHA, so scale treatments should be properly implemented and monitored to ensure adequate slip resistance. It is often stated that the single most important factor in the performance of a scales treatment is the application process. Preparation of the substrate, correct application of the product, and proper finish are the three factors that must be considered on every scales treatment.
First, the substrate surface must be thoroughly prepared prior to scales treatment, including stripping for polymerized oil and rust/scale removers for metal surfaces. Further, appropriate masking and corner guards must be in place to protect the substrate from unnecessary overspray. It is also important to ensure that there are no residues left on the surface from the pre-treatment process that might create an adverse bonding condition. Once the surface is ready, an appropriate primer should be applied to help bridge any gaps between the scales and the substrate. It is also essential to choose the right product for the job, taking into account the intended use, environmental conditions, and slip resistance requirements.
Next, correct application of the product is critical. Be sure to choose the right application technique that allows you to accurately manage and apply the product in a uniform manner. Depending on the material and opacity of the scales, multiple application methods are available; these may include Power or Airless Spraying, Brushing or Rolling, and String or Wipe application. Further, it is important to understand the limits of any overlapping coverage, as too much may lead to little or no bond to the substrate, compromising the desired slip-resistant feature as a result.
Finally, it is critical to ensure the right finish is achieved. If the material is designed to produce a mechanical finish with a textured surface, the manufacturer’s instructions should be followed to ensure adequate levels of slip-resistance are achieved.
In summary, properly implemented scale treatments are key to providing a safe environment, as they are designed to increase traction on slippery surfaces. Please keep in mind the three key factors to ensure a successful scale treatment: preparation of the substrate, correct application of the product, and proper finish.
