Removing all weld slag and stratified rust with impact tools, using non-impact methods such as scraping to remove all non-adherent materials, and feathering an adherent paint coating, are all sspc sp3 tool cleaning methods accepted by this standard.

The preparation of a sspc sp3 galvanized coating for paint or powder coating connects this standard to the galvanizing industry. Always blow off the surface with clean, dry, oil-free compressed air, brushing, or vacuum cleaning methods.

It provides photograph references for seven conditions of the surface, four unpainted and three painted surfaces. A white sspc sp3 blast will remove all coatings, mill scale, rust, oxides, corrosion products, and all other foreign products sspc sp3 a steel sspc sp3. This standard covers the removal of loose mill scale, loose rust, loose paint, and other loose detrimental foreign matter from surfaces with the use of non-powered hand tools. Power tool cleaning is to remove loose rust, mill scale, and paint.

SSPC Surface Preparation Standards

After sspc sp3 cleaning, dust is to be removed by either blowing off with clean dry air or vacuum cleaning. The preparation for painting and powder coating over a hot-dip galvanized coating, as well as the repair of damaged and uncoated areasuse SSPC-SP2 as a standard surface preparation procedure. The power tools used for this standard include sanders, wire brushes or sspc sp3, chipping hammers, rotating flaps, needle guns, hammer assemblies, and right angle grinders.

A allows uncoated areas to be power-tool cleaned before repair with zinc sspc sp3 paints in areas ps3 less critical field exposure conditions.

I am at least 16 years of age. Near-White Metal Blast Cleaning provides a greater degree of cleaning than commercial blast cleaning, but less than white metal blast cleaning. Also, avoid excessively roughening or slicking sspc sp3 surface as that may also lead to premature paint failure. 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 sspc sp3, and loose coating when viewed without magnification.


Using good cleaning practices are essential to avoiding paint failure. The brush off-blast cleaning procedure sspc sp3 in SSPC-SP16 provides an acceptable profile on hot-dip galvanized surfaces for the application of paint or powder coat.

Through the sspc sp3 of impact or abrasion from these power tools, non-adhesive particles are removed in a faster and less expensive manner than some other cleaning methods. Sspc sp3 on the procurement documents, either SSPC-VIS 3 or other various visual standards are required to be followed in conjunction with the surface preparation standards.

SSPC-SP5 provides conditions for the end condition of a white metal blast, and the materials and procedure necessary for providing the end condition.

The SSPC documents identify four conditions defined as conditions E, F, G, and H provide information on the previously painted surfaces that will xspc power tool cleaning for maintenance. Comments Have your sspc sp3 about what you just read!

SP 3, Power Tool Cleaning

This blasting method cleans less aggressively than an industrial blast clean. Please subscribe to my monthly newsletter so you don’t miss a thing. In preparation for paint and powder coating, both standards are mentioned by D sspc sp3 D in the same section.

Always note that using these references should never be a substitute to following sspcc SSPC-SP 3 power tool cleaning standards.

The size and type of abrasive media to be used depends on the profile specified sspc sp3 the coating system to be used. Adherent products — as determined sspc sp3 a dull putty knife — are not to be removed with this procedure. SSPC-SP1 removes oil and grease before cleaning with hand tools, and compressed air or a vacuum will remove dust after this cleaning procedure is completed. D states that painting sspc sp3 be performed as soon as possible after power-tool cleaning or surface grinding.

However, metals with an existing profile acceptable for painting can be cleaned with waterjetting to expose the existing profile. Waterjetting is the use of standard jetting from a nozzle at high pressures 10, psi or higher aspc prepare a surface for coating.

Standardized subjects include requirements for paints, standards for evaluating the qualifications of sspc sp3, surface preparation standards, and other topics. Besides, another benefit to using such aids is that it makes it easier to distinguish the difference between the various grades. Although photographic references can be part of the coating specification document, it can be difficult to compare surfaces sspc sp3 photographs.


This fact makes power-tool cleaning an acceptable method for surface preparation of a hot-dip galvanized coating after it has been cleaned. This surface preparation sspc sp3 is similar to that some less aggressive blast cleans. The use of such power tools allows for faster cleaning. The ASTM specifications relevant to the hot-dip galvanizing industry often reference these surface preparation standards.

D specifically calls out this standard with a condition that the water pressure sspc sp3 below psi. Consensus reference photographs are photographic aids that can assist in establishing the general appearance of the surface after SSPC-SP sspc sp3 power tool cleaning is performed. Power abrading tools also acceptably remove mill scale according to the standard. Usually occurring around after six months of weathering, a finely etched and roughened profile acceptable for paint covers the surface of the galvanized coating.

Leave me a comment in the box below. D does not specifically call out this standard, but the procedure is very similar to that of D The specifications for preparing hot-dip galvanized steel for paint and powder coating — Swpc D and D sspc sp3 — list hand sp33 cleaning as an acceptable method for smoothing sspc sp3 surface sspc sp3 removing zinc high spots of newly wspc and partially weathered coatings.

Feathering the edges of adhered sspc sp3 surfaces is also required. Typically specified when sspx sspc sp3 by sandblasting is not possible. Therefore, it is best not to apply the same consensus sspc sp3 photographs and the SSPC surface preparation standards for all projects because they will all vary based on the steel conditions and cleaning operations. We will be updating and growing this site with more and more of industrial inspection related articles. D also considers the two methods interchangeable during the surface cleaning phase of the process.

Did sspc sp3 find this sspc sp3 useful? So it is in the best interest of the owner to provide the contractor with sample surfaces of what is expected. After a galvanized surface sl3 been acceptably cleaned of oil, grease, and similar products, this brush blasting can be applied in order to create an acceptable profile.
