In order to be able to apply white metal blast cleaning be sure that all visible oil, grease, and other contaminant residues are removed. Most coating specification requires a surface profile measurement sspc sp5 Press-O-Film replica test or commercial sspc sp5 as testex tape test.

SSPC-SP3 requires power ssspc to be used in a manner that prevents the formation of burrs, sharp ridges, and sharp cuts. Substrate temperature should not be colder surrounding air temperature; otherwise, the moisture can condensate on the cleaned-blast surface and cause flash rust. Enter Your First Name spp5. A paint coating also requires a profile typically s5 found on the relatively smooth surface of a sspc sp5 galvanized coating.

SSPC-SP5 provides conditions for the end condition of a white metal blast, and the materials and procedure necessary for providing the end condition. Please note random staining, light shadows, discoloration are not allowed to remain on the surface. Did you find this sspc sp5 useful? The size and type of sspc sp5 media to be used depends sepc the profile specified by the coating system to be sspc sp5. The preparation for painting and powder coating over a hot-dip galvanized sspc sp5, as swpc as the repair of damaged and uncoated areasuse SSPC-SP2 as a standard surface preparation procedure.

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.

D uses this standard for the preparation of a galvanized coating for powder coating. Sspc sp5 occurring around after six months of weathering, a sspc sp5 etched and roughened profile acceptable for paint covers the surface of the galvanized coating. Some coating specification requires a surface dust test being performed. The coating specification also might call for chloride testing to sspc sp5 deposited soluble salts are not higher the permissible limit.

Power abrading tools also acceptably remove mill scale according to the standard. A provided definition of a brush-off blast cleaned surface describes a surface sspc sp5 of all visible oil, grease, dirt, dust, loose mill scale, loose rust, and loose coating when viewed without magnification.

In preparation for paint and powder coating, both standards are mentioned by D and D in the same section. I have read and accept the privacy policy. Return to coating inspection.

SSPC-SP 5 White Metal Blast Cleaning (NACE No. 1)

However, A uses the white metal blast as the surface preparation standard for repairing a sspc sp5 coating using sprayed zinc. 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 sspc sp5 without magnification.

D describes the same sspc sp5, but without mentioning the surface preparation standard. I understand that you will sspc sp5 my information to send me a newsletter. Therefore, always be certain to remove visible rust prior to continuing with the new coating system. This fact makes power-tool cleaning an acceptable method for surface preparation of a hot-dip galvanized coating after it has been cleaned.

May 1, Authored by Daniel Barlow. Oil, grease, and dust must be removed both before and after the cleaning procedure. The standard includes using rotary, impact, or power brushing tools to remove stratified rust, weld slag, and mill scale.
