The specifications should state acceptable maximum levels of salt contamination and require testing after surface preparation has been performed and prior to painting.
While each of the three standards invokes the use of power tools, the degree of coating removal and surface roughness requirements vary. Spsc tool cleaning will not remove grease and oil contamination from the surface.

This includes personalizing content and advertising. Life expectancy of coating system — The life expectancy of a coating ssoc will influence the level of power tool cleaning selected. The configuration of the work surface may dictate the degree of power tool cleaning possible. Chloride removal agents can also be added to the pressure washing water. Inspection Instruments Pipeline Coatings — Volume 2: Costs — The associated labor costs for surface preparation will vary inversely proportionally to the production rates listed above.
To better understand the differences a quick summary of each is provided below: Leave this field empty. Generic production rates for the 3 levels of surface cleanliness are shown in the table below.
Note that several factors can affect production rates; the rates zspc are simply for relative comparisons. For the purposes of this discussion we are going xp assume that due diligence has been done and that power tool cleaning is a viable option for maintenance painting work.
The primary difference between the three SSPC standards is the degree of cleanliness and roughness required. Additional cleaning will need to be performed if soluble salt contamination is present and required to be mitigated.
Similarly, power tool cleaning will not remove soluble salt contamination.
Surface Preparation by Power Tool Cleaning… What to Specify When
Factors to consider when swpc the level of power tool cleaning: One of the key components to the success of any coatings maintenance project is the degree of surface preparation both specified and performed. An increase in the degree of surface cleanliness specified results in an increase in a project cost.
Wspc — Areas that are difficult to access, like small internal spaces, back-to-back angles, etc. For example, spot repairs that are expected to provide 5 years of corrosion protection as a stopgap until more significant maintenance painting work can be performed may require a lesser degree of surface preparation SSPC-SP 3 than a coating system that is expected to last 15 years.

Surface Preparation by Power Tool Cleaning – What to Specify WhenKTA University
First, all three standards address the preparation of steel substrates using power tools. My father wants one of the walls in his house to undergo surface preparation. April 17, at 7: The same types of power tools may be used to prepare surfaces for all three standards and may be electric or pneumatic powered.
Some of the common types of power tools include grinders, cup sspc brushes, wire wheels, pneumatic chipping hammers, rotating flaps, scalers, and needle guns. Schedule — Production rates to achieve the required degree of surface cleanliness vary between the three standards.
Your email address will not be published. Coating manufacturer product requirements — Different coating systems have different surface preparation requirements.
