Painting and Sandblasting

It is impossible to overstate the benefits of a suitable finishing for your metal fabrication project’s visual appeal and protective qualities. Finding the appropriate paint and applying it properly is so crucial. In addition to wanting something that will resist the battery and exposure your finished piece will experience, you also want your paint to look fantastic. This is where painting and sandblasting procedures can be useful.

Spraying water- or solvent-based paint onto a surface constitutes traditional wet painting.

Blasting and painting companies in UAE follow three steps procedures: pre-treatment, application, and curing.

Following blasting, abrasion is used to clean the part’s surface (removing grease, old coatings, dust, or rust). In order for the paint to adhere to and bind with the surface, it must first be etched and scratched. Paint chips more readily without this procedure. By using sandblasting, the oxidation on the steel is removed. Rust will develop quickly if it is exposed, improperly finished, and placed in the incorrect setting. Before moving on to the following stage, the part is given time to dry safely.

A zinc-based primer and the powder are electrically applied using an electrostatic gun after pre-treatment (reminiscent of a hairdryer). The application is accelerated and evenly distributed with the help of the electrostatic gun. As surplus paint is resisted, this also has the added benefit of reducing overspray.

The item is then placed in an oven to cure and allow the primer to set. The final layer is applied once the priming has been heated and gelled. Similar to how the primer is applied, the finish can be customized. The component is heated once more to complete the curing process. The end result is a polished, bright surface.

The Benefits of Painting and Sandblasting

It is now time to discuss why the sandblasting and painting approach has been deemed to be preferable to wet painting after addressing the distinctions between the two painting techniques. Durability and lifespan are the primary advantages of the former. More than just a nice paint job is produced by blasting and painting. Simple wet paint does not provide the same level of protection against environmental threats as it is significantly more affordable and offers:

  • Corrosion: A single coat of paint applied at just 3 mils gives corrosion protection comparable to that provided by three coats of paint applied at the same thickness. Powder-coated items offer good weather ability, whereas wet paint is typically utilized indoors.
  • Economical: Spent spray can be recovered and reused because it is a solid product. Overspray is less likely, and between 60 and 70 percent of blast and paint is transferred effectively (compare to the much lower 30 to 35 percent transfer rate of wet paint).
  • Production Advantages: Faster than wet paint, blasting and painting gets items ready for use. A chassis is ready to be handled or further machined as soon as it has cooled. Powder coating lines require less supervision, thus there is less downtime.
  • Chemical Resistance: Has brake fluid ever unintentionally spilled into the paint of a car? If so, you have already witnessed the harm. The finish is resistant to chemicals with blast and paint. The paint is unharmed and may simply be cleaned up.

The application of wet paint simply using more conventional techniques pales in comparison to the blast and paint process in many aspects. Powder coating has benefits that wet paint can’t match, like lower prices, resilience, and flawless finishes.
