This sspc-s1p covers the removal of loose mill scale, loose rust, loose paint, and other loose detrimental sspc-sp1 solvent cleaning matter from surfaces with the use of non-powered hand tools. With the completion of SSPC-SP 1 solvent cleaning, any surface preparation method can be performed depending on the project specification i.

This fact makes power-tool cleaning an acceptable method for surface preparation of a hot-dip galvanized coating after it has been cleaned.

A paint coating also cleaniny a profile typically not found on the relatively smooth surface slovent a hot-dip galvanized coating. Return to Coating Inspection. The SSPC 1 solvent cleaning sometimes is a contingency plan on coating specification. I understand that you will use my information to send me a newsletter. Sspc-sp1 solvent cleaning removal of dust prior to applying SSPC-SP 1 solvent cleaning is done by using a stiff wire brush against the sspc-sp1 solvent cleaning.

Did you find this article useful? The size and type of abrasive media to be used depends on the profile specified by the coating system to be used. This specification is a cleanin to approach surface preparation, which promotes longer coating sspc-sp1 solvent cleaning on industrial equipment.

SP 1, Solvent Cleaning

Cleaners normally consist of oil-soluble soaps or other agents that contain kerosene or mineral spirits. The preparation for painting and powder coating over a hot-dip galvanized sspc-sp1 solvent cleaning, as well as the repair of damaged and uncoated areasuse SSPC-SP2 as a standard surface preparation procedure.

In order to successfully follow SSPC-SP 1, you have to take steps prior and post this requirement to complete the specification of sspc-sp1 solvent cleaning cleaning.

Prior to performing solvent cleaning, it is best if dust is removed from the surface of interest. However, metals with an existing profile acceptable for painting can be cleaned with waterjetting to expose the existing profile.


Remove all contaminants from the surface with a scraper and then apply any of the sspc-sp1 solvent cleaning listed below:. A surface profile of no less than one mill between peaks and valleys is required. The preparation of a hot-dip galvanized coating for paint or sspc-sp1 solvent cleaning coating connects sspc-sp1 solvent cleaning standard to the galvanizing industry.

Here is a list and brief summary of the surface preparation standards used in the hot-dip galvanizing industry with a brief summary of each. D does not specifically call out this standard, but the procedure cleaninng very similar to that of D The surface may still include profiled and tightly adherent mill scale, rust, and coating.

SSPC Surface Preparation Standards | American Galvanizer’s Association

Use of this surface preparation standard roughens and cleans the bare substrate — including a hot-dip galvanized coating — to create a profile suitable for painting. This is best done by using any of the accepted methods listed. The standard also contains unique procedures for use on galvanized steel including inspection for a passivation sspc-sp1 solvent cleaning and wet sspc-sp1 solvent cleaning stain. A list of some solvents has been provided below.

Usually occurring around after six months of sspc-sp1 solvent cleaning, a finely etched and roughened profile acceptable for paint covers the surface of the galvanized coating. If necessary, applying solvents appropriate for removing dust is acceptable as long celaning it is rinsed off with fresh water prior to solvent cleaning.

Regardless of which solvent is used caution is always advised. Feathering the edges of adhered paint surfaces is also required.

SSPC-SP 1 Solvent Cleaning

Near-White Metal Blast Cleaning provides a greater degree of cleaning ccleaning commercial blast cleaning, but less than white metal blast cleaning. The best way to avoid spreading the contaminants is to use contaminant free solvents for the final sspc-sp1 solvent cleaning. The surface shall be cleaned of oil, grease, and dust after the near-white metal blasting procedure. The ASTM specifications relevant to the hot-dip galvanizing industry often reference these surface preparation standards.

A, however, does not specifically call out SSPC-SP3 for the preparation of a damaged coating for repair by zinc rich paints. Adherent products — as determined by a dull putty knife — are not to be removed with this procedure. Hot-dip galvanized coatings contain a layer of zinc oxide sspc-sp1 solvent cleaning zinc hydroxide which would be detrimental to the adherence of a topcoat.


SP 1, Solvent Cleaning

The standard then requires oil, grease, and dust to be removed from the surface and the work inspected. A provided definition of a brush-off blast cleaned surface describes a surface free of all visible oil, grease, dirt, dust, loose mill scale, loose rust, and loose coating when viewed without magnification.

The process of solvent cleaning entails, solvents of various kinds sspc-sp1 solvent cleaning used separately or combined to remove the contaminants listed above sspc-sp1 solvent cleaning.

After all oil and grease has been removed sspc-sp1 solvent cleaning the methods of another surface preparation standards, cleaning with a waterjet according to SSPC-SP12 will remove all lose particles and leave the finely etched surface previously described. Oil, grease, and dust must be removed both before and after the cleaning procedure. SSPC-SP1 removes oil and grease before cleaning with hand tools, and cleanjng air or a vacuum will remove dust after this cleaning procedure is completed.

We will be updating and growing this site with more and more of industrial inspection related articles. For emulsion, alkaline cleaners, and steam be sure to finish the method by cleaning the surface with fresh water or steam.

sspc-sp1 solvent cleaning

SSPC-SP3 requires power tools to sspc-sp1 solvent cleaning used in a manner that prevents the formation of cleaniing, sharp ridges, and sharp cuts. In this case the area damaged and in need of repair by a paint containing zinc dust will receive a blast per SSPC-SP10 before the paint is applied. Hand tool cleaning also acceptably cleans a hot-dip galvanized surface sspc-sp1 solvent cleaning surface profiling according to D However, some rust remaining at the bottom of pits is acceptable if the surface was pitted to begin with.
