What is an important factor when using waterjetting in surface preparation?

When utilizing waterjetting in surface preparation, a key advantage is its ability to effectively remove soluble contaminants from surfaces. Waterjetting employs high-pressure water streams, which can dislodge and wash away various impurities, including salts, oils, and other soluble substances that may interfere with the adhesion of subsequent coatings. This cleansing action is vital for ensuring that the surface is clean enough to provide a strong bond for the coatings being applied.

The process does not inherently create a specific surface profile, nor is it limited to only new surfaces. While waterjetting can be used in conjunction with abrasive blasting, it is not mandatory for it to always follow this method. The flexibility and effectiveness of waterjetting in addressing soluble contaminants make it a crucial technique in surface preparation.
