When this limestone stela entered the collection in 1937 from the New York Historical Society the surface was described as “blackened” and “much broken”. In 2009 Conservation treated the object for a traveling exhibition and tested the stone for soluble salts using filter paper wet with deionized water. When dry, the paper was removed and re-wet with deionized water and tested for nitrates using acidified diphenylamine and chlorides using acidified silver nitrate, and sulphates using acidified barium chloride. The records indicate the samples were wildly positive for nitrates, slightly positive for chlorides, and did not register positive for sulphates. At this time cleaning tests were done using erasures - Staedler and Mars white vinyl erasure and Faber Castell PVC free erasure. There was somewhat of a cleaning effect with the Staedler and Mars cleaning better than the Faber Castell. However, both erasures required a fair amount of pressure that put the flaking stone at too great a risk. Wet cleaning methods were tested using deionized water/ethanol (1:1), acetone, and deionized water, chased with acetone. All methods were applied with cotton swabs. The deionized water was the most effective, with the least amount of pressure. However, because of the presence of soluble salts in the stone water was not a viable treatment option. In 2018 the Conservation Department purchased a laser and this month this stela was finally able to be cleaned.

Structural Steel : Why Surface Preparation Is Necessary

Structural steel components are used in many industries, including metal fabricator, steel structure construction and construction equipment, mining, shipbuilding, and the production of all kinds of heavy-duty vehicles, trucks, railway vehicles, mining and agricultural implements. In the construction of metal tanks, silos, bridges, building, ships, or production of equipment that must withstand heavy loads, steel is selected for its strength and durability.

To live up to its full potential and prevent premature failure, the steel must be guarded against corrosion with a protective coating. Laser blasting plays an indispensable role in preparing the steel surface for such coatings. Partnering with a Laser blasting expert such as ALFA LASER can help you determine the Laser blasting equipment and processing required for your structural steel components.

In a series of blog posts, Alfa Laser will answer the most common questions about the surface preparation and coating of structural steel.

We begin with a basic question: Why do structural steel components need to be prepared for protective paint coating?

The answer, in short, is for the best coating results and longevity.

Goals of Surface Preparation

If not covered with a suitable, protective coating, structural steel components are prone to rust quickly and fail with potentially catastrophic consequences.

The effective life of a coating of anti-corrosive paint applied to a steel surface is largely dependent on how thoroughly the surface has been prepared prior to painting.

Structural steel components requiring protective coatings include:

Beams (I‐beams, H‐beams, channels, angles, etc.).

Steel plates.

Round bars and pipes.

Weldments.

Preparing and coating the surfaces effectively increases their durability and improves their appearance.

Issues to Watch For

A variety of factors can create surface issues necessitating proper preparation before coating such as the steel rolling process itself and prolonged exposure to the elements, water, or chemicals.

Specific surface factors in need of attention include:

The presence of rust or mill scale.

The presence of surface contaminants.

Surface profile or roughness

The presence of these and other contaminants on the steel surface can cause premature coating failure. Painting a surface with the wrong surface profile/roughness can also cause premature failure or drastically increase paint consumption.

To achieve good coating adhesion, the surface profile generally must become somewhat rougher, increasing the overall surface area.

Tools of the Trade

While numerous cleaning techniques such as sandblasting, hand and power tool cleaning, high-pressure water jetting, and degreasing are used for surface preparation, Laser Cleaning is the most advanced industrial paint preparation method for structural steel components.

This method does not utilize any consumables, very fast, flexible and is eco-friendly.

Surface issues for structural steel components vary greatly. Fortunately, users can rely on detailed standards describing the visual evaluation of surfaces and procedures regarding the correct surface preparation for coating and painting.

The most commonly used standards address different surface characteristics of steel components and preparation requirements:

ISO 8501 – Visual assessments of surface cleanliness, rust, and preparation grades of uncoated steel substrates

ISO 8502 – Tests for the assessment of surface cleanliness

ISO 8503 – Evaluates surface roughness characteristics of blast‐cleaned steel substrates

AMPP – The Society for Protective Coatings (SPCC) and the National Association of Corrosion Engineers International (NACE) have merged to for the Association for Materials Protections and Performance (AMPP)

ASTM D 2200 – Standard practice for use of pictorial surface preparation standards and guides for painting steel surfaces created by the American Society for Testing and Materials
