Learn the Key First Steps to Extending Storage Tank Life

by Kevin Morris

Proper surface preparation readies a surface for good coating adhesion and prevents premature coating failure.¬†¬†When preparing steel and concrete surfaces, certain critical issues must be addressed and standards followed to achieve maximum benefit from today‚Äôs high performance, anti-corrosion coatings. Join Bruce Snyder for the Sherwin-Williams webinar Making the First Step Count – Surface Preparation Standard. […]

Painting Galvanized Steel

by Bruce Snyder

Hot Dip Galvanizing is the process of “dipping” a steel structure in a molten vat of zinc.¬† This zinc will then metallurgically bond to the steel, protecting the steel substrate from corroding.¬†¬† The process consists of dipping the steel in a caustic bath to remove the organic contamination, followed by dipping the steel in an […]

Surface Preparation: Inspection – Part III

by Tony Ippoliti

The reason we prepare a¬†surface prior to painting is not well understood.¬† We do it because we think we’re supposed to do it …¬† but why? According to The Society for Protective Coatings (SSPC)¬† Surface Preparation Commentary (SSPC-COM), we prepare a surface “to remove surface contaminants that can induce premature coating failure” and “to provide […]

Surface Preparation: “Tooling Around” – Part II

by Tony Ippoliti

In the previous surface preparation post, I discussed steel making and the necessity for abrasive blasting to remove mill scale.¬† But abrasive blasting, especially for maintenance work,¬†¬†cannot always be achieved because a facility owner¬†may have restrictions on dust and particulate generation and there may be (and probably is) equipment operating 24/7.¬† Plus, you need some […]

Surface Preparation: It’s A “Blast” – Part I

by Tony Ippoliti

The cover of the August 2007 issue of Modern Steel Construction highlighted an article within its pages: “Making Steel“. A¬†Google search of the words “making steel” delivers over 61 million hits. One of these, Key-to-Steel,¬†¬†provides several examples of the steel-making process.¬† Fascinating.¬† There’s much information available about the making of steel. Briefly, “virgin” steel is […]
