Costs — The associated labor costs for surface preparation will vary inversely proportionally to the production rates listed above. Leave this field empty.
The specifications should state acceptable maximum levels of salt contamination and require testing after surface preparation has been performed and prior to painting. This includes personalizing content and advertising. In many instances, chloride contamination can be reduced to acceptable levels by pressure water cleaning.

Factors to consider when selecting the level of power tool cleaning: Power tool cleaning will not remove aspc and oil contamination from the surface. Generic production rates for the 3 levels of surface cleanliness are shown in the table below. Additional cleaning will need to be performed if soluble salt contamination is present and required to be mitigated.
My father wants one of the walls in his house to undergo surface preparation. One of the key components to the success of any coatings maintenance project is the degree of surface preparation both specified and performed. While each of the three spc invokes the use of power tools, the degree of coating removal and surface roughness requirements vary.
April 17, at 7: The primary difference between the three SSPC standards is the degree of cleanliness and roughness required. Similarly, power tool cleaning will not remove soluble salt contamination.
The same types of power tools may be used to prepare surfaces for all three standards and may be electric or pneumatic powered. Note that several factors can affect production rates; the rates shown are simply for relative comparisons.
Chloride removal agents can also be added to the pressure washing water. Life expectancy of coating system — The life expectancy of a coating system will influence the level of power tool cleaning selected.
To better understand ssspc differences a quick summary of each is provided below: Some of the common types of power tools include grinders, cup wire brushes, wire wheels, pneumatic chipping hammers, rotating flaps, scalers, and needle guns.
Access — Areas that are difficult to access, sdpc 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. Coating manufacturer product requirements — Different coating systems have different surface preparation requirements.
An increase in the degree of surface cleanliness specified results in an increase in a project cost. Your email address will not be published. It is an indirect or automatic requirement of each of the three standards.
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. Inspection Instruments Pipeline Coatings — Volume 2: 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.
Schedule — Production rates to achieve the required degree of surface cleanliness vary between the three standards.
