Inspection Instruments Pipeline Coatings — Volume 2: In many instances, chloride contamination can be reduced to acceptable levels by pressure water cleaning.
Your email address will not be published. Life expectancy of coating system — The life expectancy of a coating system will influence the level of power tool cleaning selected. Costs — The associated labor costs for surface preparation will vary inversely proportionally to the production rates listed above. One of the key components to the success of any coatings maintenance project is the degree of surface preparation both specified and performed.
Surface Preparation by Power Tool Cleaning… What to Specify When
Additional cleaning will need to be performed if soluble salt contamination is present and required to be mitigated. Leave this field empty.
Chloride removal ep can also be added to the pressure washing water. To better understand the differences a quick summary of each is provided below: The primary difference between the three SSPC standards is the degree of cleanliness and roughness required.
Surface Preparation by Power Tool Cleaning – What to Specify WhenKTA University
For the purposes of this discussion we are going to assume that due diligence has been done and that power tool cleaning is a viable option for maintenance painting work.

The same types of power tools may be used to prepare surfaces for all three standards and may be electric or pneumatic powered. An increase in the degree of surface cleanliness specified results in an increase in a project cost.
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. If a specific coating system or systems are included in the specification, the dp of surface preparation performed must be consistent with the coating requirements and the specified surface preparation.
Sxpc father wants one of the walls in his house to undergo surface preparation. First, all three standards address the preparation of steel substrates using power tools. Power tool cleaning will not remove grease and oil contamination from the surface.
Coating manufacturer product requirements — Different coating systems have different surface preparation requirements. Access — Areas that are difficult to access, like small internal spaces, back-to-back angles, etc.
This includes personalizing content and advertising. Schedule — Production rates to achieve the required degree of surface cleanliness vary between the three standards.

Factors to consider when selecting the level of power tool cleaning: The specifications should state acceptable maximum levels of salt contamination and require testing after surface preparation has been performed and prior to painting.
Similarly, power tool cleaning will not remove soluble salt contamination.
The configuration of the work surface may dictate the degree of power tool cleaning possible. While each of the three standards invokes the use of power tools, the degree of coating removal and surface so requirements vary.
