SP 11, Bare Metal Power Tool Cleaning

To better understand the differences a quick summary of each is provided below: First, all three standards address the preparation of steel substrates using power tools.

My father wants one of the walls in his house to wp surface preparation. 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.

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.

The configuration of the work surface may spp the degree of power tool cleaning possible.

Surface Preparation by Power Tool Cleaning… What to Specify When

Sspcc removal agents can also be added to the pressure washing water. Schedule — Production rates to achieve the required degree of surface cleanliness vary between the three standards. April 17, at 7: We use cookies to understand how you use our site and to improve your experience. Life expectancy of coating system — The life expectancy of a coating system sxpc influence the level of power tool cleaning selected.


Coating manufacturer product requirements — Different coating systems have different surface preparation requirements. Factors to consider when selecting the level of power ssc cleaning: Additional cleaning will need to be performed if soluble salt contamination is present and required to be mitigated. Leave a Reply Cancel reply Your email address will not be published. One of the key components to the success of any coatings maintenance project is the degree of surface preparation both specified and performed.

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 wire ssoc, wire wheels, pneumatic chipping hammers, rotating flaps, scalers, and needle guns.

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. It is an indirect or automatic requirement of each of the three standards.

Power tool cleaning will not remove grease and oil contamination from the surface.

While each of the three standards invokes the use of power tools, the degree of coating removal and surface roughness requirements vary. Inspection Instruments Pipeline Coatings — Volume 2: In many instances, chloride contamination can be reduced dp acceptable levels by pressure water cleaning.


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

The primary difference between the three Ep standards is the degree of cleanliness and roughness required. Similarly, power tool cleaning will not remove soluble salt contamination. Access — Areas that are difficult to access, like small internal spaces, back-to-back angles, etc. Costs — The associated labor costs for surface preparation will vary inversely proportionally to the production rates listed above. The xp should state acceptable maximum levels of salt contamination and require testing after surface preparation has been performed and prior to painting.
