Coating manufacturer product requirements — Different coating systems have different surface preparation requirements. This includes personalizing content and advertising. The same types of power tools may be used to prepare surfaces for all three standards and may be electric or pneumatic powered. Factors to consider when selecting the level of power tool cleaning: One of the key components to the success of any coatings maintenance project is sspd degree of surface preparation both specified and performed.
The primary difference between the three SSPC standards is the degree of cleanliness and roughness required. My father wants one of the walls in his house to spc surface preparation.
Similarly, power tool cleaning will not remove soluble salt contamination. While each of the three standards invokes the use of power tools, the degree of coating removal and surface roughness requirements vary. Some of the common types of power tools include grinders, cup wire brushes, wire wheels, pneumatic chipping hammers, rotating flaps, scalers, and needle guns.
In many instances, chloride contamination can be reduced to acceptable levels by pressure water cleaning. Additional cleaning will need to be performed if soluble salt contamination is present and required to be mitigated.
It is an indirect or automatic requirement of each of the three standards. Wp — Areas that are difficult to access, like small internal spaces, back-to-back angles, etc.

The specifications should state acceptable maximum levels of salt contamination and require testing after surface preparation has ssc performed and prior to painting. Power tool cleaning will not remove grease and oil contamination from the surface. Costs — The associated labor costs for surface preparation will vary inversely proportionally to the production rates listed above.
The configuration of the work surface may dictate the degree of power tool cleaning possible.

Your email address will not be published. An increase in the degree of surface cleanliness specified results in an increase in a project cost.
Generic production rates for the 3 levels of surface cleanliness are shown in the table below. 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.
First, all three standards address the preparation of steel substrates using power tools. Leave a Reply Cancel reply Your email address will not be published. Leave this field empty. To better understand the differences a quick summary of each is provided xspc Chloride removal agents can also be added to the pressure washing water.

Inspection Instruments Pipeline Coatings — Volume 2: Life expectancy of coating system — The life expectancy of a coating system will influence the level of power tool cleaning selected.
April 17, at 7: If a specific coating system or systems are included in the specification, the degree of surface preparation performed must be consistent with the coating requirements and the specified surface preparation. Schedule — Production rates to achieve the required degree of surface cleanliness ssspc between the three standards.
