How much courage do you have? Do you have the guts to go beyond the delusion of the day? Dare to see that we can
This standard is covering all aspects related to the determination of contaminants that are required to removed before coating application. It is therefore titled: “Preparation

This depends on the type of abrasive, the amount of cycles that the abrasive can be re-used, and the density of the abrasive. With a
It is important to understand that the VIS Guides only describes the pictorial standard and does not constitute the standard. It is to be used
Standards are available from several organizations that provide direction for using various methods to obtain an anchor profile measurement. Available standards include but are not
Due to extra surface area created by the surface profile and roughness with required peak coverage, extra paint is needed. A rule of thumb for
If you speak to any abrasive blast contractor, they will openly state that the air pressure achieved at the blast nozzle equates to the efficiency
Yes, you need to verify the presence of salts to prevent osmosis and thus osmotic pressure. This will create blisters or cracks on the coating
Mill scale is iron oxide that forms on a surface during hot rolling of steel. During rolling, the high temperature involved causes oxide to form
Coating specifications should always incorporate or reference one of the written and/or visual/photographic surface preparation standards. Such standards exist to eliminate misinterpretation, questions, disagreement, related
Many of the standards on surface preparation, coating and cathodic protection are also recognised and integrated or harmonized to: American Society for Testing Materials (ASTM)
Some of the most commonly used methods are: Hand tools Power tools Abrasive blasting Centrifugal Wheel Blasting Water Blasting To achieve the different surface preparation
The most common parameters to be considered when choosing an abrasive are: Shape – angular or round Hardness – hard or soft Density – heavy
Yes, Surface preparation of the steel before external coating application is the foundation of any corrosion control program. Any compromise made in the degree of
Why hasn’t anybody else told me these things before? It would have really helped me to save costs, but more important, it would safed me from the frustration to go through a learning cycle that many others have been through.
Your time is scarce. But where do you find independent information that is up to date?
