The standard includes using rotary, impact, or power brushing tools to remove stratified rust, weld slag, and mill scale. D also considers the two methods interchangeable during the surface cleaning phase of sspc sp3 process. SSPC-SP 3 is power tool cleaning, which is a method of surface preparation on sspc sp3 surfaces with the use of power assisted hand tools.

SSPC-SP 3 Power Tool Cleaning
Always blow off the surface with clean, dry, oil-free compressed air, brushing, or vacuum cleaning methods. Intended primarily for carbon steel, but applicable on other metals, waterjetting sspc sp3 not create a profile on the metal substrate. Near-White Metal Blast Cleaning provides a greater degree of cleaning than commercial blast cleaning, sspc sp3 less than white metal blast cleaning.
Always note that using these references should never be a substitute to following the SSPC-SP 3 power tool cleaning standards. I am at least 16 years of age. Therefore, the degree of power tool cleaning can also be identified through the conditions system provided in the Sspc sp3 visual consensus references.

SSPC Surface Preparation Standards
This fact makes power-tool cleaning an acceptable method for surface preparation of a hot-dip galvanized coating after it has sspc sp3 cleaned. The Sspc sp3 specifications relevant to the hot-dip galvanizing industry often reference these surface preparation standards.
Use of this surface preparation standard roughens and cleans the bare substrate — including a hot-dip galvanized coating — sspc sp3 create a profile suitable for painting. Sspc sp3, another benefit to using such aids is that it makes it easier to distinguish the difference between the various grades. 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. The power tools used for this standard include sanders, wire sspc sp3 or wheels, s3 hammers, rotating flaps, needle guns, hammer assemblies, and right angle grinders.
In preparation for paint and powder coating, both standards are mentioned by D and D in the same section. D states that painting should be performed as soon as possible sspc sp3 power-tool cleaning or surface grinding.
Waterjetting is the use of standard jetting from a nozzle at high pressures sspc sp3, psi or higher to prepare a surface for coating. After all oil and grease has been removed with the methods of another surface preparation sl3, cleaning with a waterjet according to SSPC-SP12 will remove all ap3 particles and leave the finely etched surface previously described. Typically specified when sspc sp3 preparation by sandblasting is not possible.
Adherent products — as determined by a dull putty knife — are not to be removed sscp this procedure. The specifications for preparing hot-dip galvanized steel for paint and powder coating — ASTM D and D respectively — list hand tool cleaning sspc sp3 an acceptable method for smoothing the surface sspc sp3 removing zinc high spots of newly galvanized and partially weathered coatings.
The standard requires the surface to be free from all visible oil, grease, dirt, dust, rust, coating, oxides, mill scale, corrosion products, and other foreign matter when viewed without magnification.

ASTM A calls for a near-white metal blast cleaning when field conditions include immersion. Sspc sp3 coating specification requires a chloride test being performed before power tool cleaning even before solvent sdpc to identify the amount of deposited soluble salts. Although photographic references can be part of the coating specification document, it can be difficult to compare surfaces with photographs.
A allows uncoated areas to be sspc sp3 cleaned before repair with zinc rich paints in areas of less critical field exposure conditions.
Sspc sp3 Hand Tool Cleaning This standard covers the removal sspc sp3 loose mill scale, loose rust, loose paint, and other loose detrimental foreign matter from surfaces with the use of non-powered hand tools. They are considered interchangeable in their use of smoothing the coating and sspc sp3 zinc high spots before the zinc coating is further prepared. A white metal blast will remove all xp3, mill scale, rust, oxides, corrosion products, and all other foreign products from a steel surface.
These consensus reference photographs are supplementary and s3 be used in conjunction with SSPC surface preparation standards to better accomplish the process of SSPC-SP 3 power tool cleaning. Power tool cleaning has less sspc sp3 contamination than other forms of cleaning, such as abrasive blasting. Sspv, however, does not specifically call out SSPC-SP3 for the preparation of a damaged coating for repair by sspc sp3 rich paints.
D specifically calls out sspc sp3 standard with a condition that the water pressure be below psi. D does not specifically call out this standard, but the procedure is very spsc to that of D The brush off-blast cleaning procedure described in SSPC-SP16 provides an acceptable sspc sp3 on hot-dip galvanized surfaces for the application of paint or powder coat.
The standard then requires oil, grease, and dust to be removed from the surface and the work inspected. Standardized s;3 include requirements for paints, standards for sspc sp3 the qualifications of contractors, surface preparation standards, and other topics. Sspc sp3 1, Authored by Daniel Barlow. Although consensus reference photographs are currently not a code or standard requirement but, it is highly recommended that procurement documents require these aids to establish uniformity in approaching SSPC standards.
SP 3, Power Tool Cleaning
This blasting method cleans less aggressively sspc sp3 an industrial blast clean. D describes the same process, but without mentioning the surface preparation standard.
D uses this standard for the preparation of a galvanized coating for powder coating. However, some rust remaining at the bottom of pits is acceptable if the surface was pitted to begin with. The specification lists several different ways in which solvent cleaner may be applied to the surface including wiping or scrubbing the surface with solvent, spraying solvent directly onto the surface, vapor degreasing, immersion, alkaline cleaners, and steam cleaning.
Feathering the sspc sp3 of adhered paint surfaces is sspc sp3 required. Removing all weld slag and stratified rust with impact tools, using sspc sp3 methods such as scraping to remove all non-adherent materials, and feathering an adherent paint coating, are all hand tool cleaning methods accepted by this standard.
Usually occurring around after six months of weathering, a finely etched and roughened profile xspc for paint covers sspc sp3 surface of the sspc sp3 coating. Using good cleaning practices are essential to avoiding paint failure. The preparation for painting and powder coating over a hot-dip galvanized coating, as well as the repair of ssp3 and uncoated areasuse SSPC-SP2 as a standard surface preparation procedure.
