Surface Preparation by Power Tool Cleaning… What to Specify When
Similarly, power tool cleaning will not remove soluble salt contamination. The primary difference between the three SSPC standards is the degree of cleanliness sspc sp 11 roughness required. For example, spot repairs that are expected to provide 5 years of corrosion protection as a stopgap until more significant maintenance painting work sspc sp 11 be performed may require a lesser degree of surface preparation SSPC-SP 3 than a coating system that is expected to last 15 years.
Schedule — Production rates to achieve the required degree of surface cleanliness vary between the three standards.
Surface Preparation by Power Tool Cleaning – What to Specify WhenKTA University
Your email address will not be published. Factors to consider when 11 the level of power tool cleaning: The configuration of the sspc sp 11 surface may dictate the degree of sspc sp 11 tool cleaning possible.
Additional cleaning will need to be performed if soluble salt contamination is present and required to be mitigated. The specifications should state acceptable maximum levels of salt contamination and require testing after swpc preparation has been performed and prior to painting.
Life expectancy of coating sspc sp 11 — The life expectancy of a coating system will influence the level of power tool cleaning selected. Note that several factors can affect production rates; the espc shown are simply for relative comparisons.
The same types of power tools may be used to prepare surfaces for all three sspc sp 11 and may be electric or pneumatic powered. Power tool cleaning will not remove grease and oil contamination from the surface. April 17, at 7: Leave a Reply Cancel reply Your email address will not be published.
Generic sspc sp 11 rates for the 3 levels of surface cleanliness are shown in the table below. For the purposes of this discussion we are going to sspc sp 11 that due diligence has been done and that power sspc sp 11 cleaning is a viable option for maintenance painting work.
Save my name, email, and website in this browser for the next time I comment. Some of the common types of power tools include grinders, cup wire brushes, wire wheels, pneumatic chipping hammers, rotating flaps, scalers, and needle guns. Costs — The associated labor costs for surface preparation will vary inversely proportionally to the production rates listed above. First, all three standards address the preparation of steel substrates using power tools.
One of the key components to the success of any coatings maintenance project sspc sp 11 the degree sspd surface preparation both specified and performed. Coating manufacturer product requirements — Different coating systems have different surface preparation requirements.
An increase in the degree of surface cleanliness sspc sp 11 results in an increase in a project cost. It is an indirect sspc sp 11 automatic requirement of each of the three standards.
Standard: SSPC SP 11
If a specific coating system or systems are included in the specification, sspc sp 11 degree of surface sspc sp 11 performed must be consistent with the coating requirements and the specified surface preparation. While each of the three standards invokes the use of power tools, the degree of coating removal and surface roughness requirements vary. In many instances, chloride contamination can be reduced to acceptable levels by pressure water cleaning.
My father wants one of the walls in his house to undergo surface preparation.
