Prep your surfaces the right way
Thanks to increasing advances in technology, surface preparation has never been easier, or more precise. Surface preparation ensures that surfaces are free from contaminants, corrosion, rust, and old coatings, allowing new materials to adhere effectively.
There are three techniques (sandblasting, shot blasting, and wet blasting) that many project undertakers prefer due to their efficiency and precision. But the real question stands: what are they, what are they used for, and which surface prep method is best for my project?
Sandblasting – an abrasive method for surface dirt that won’t budge
Sandblasting, also known as abrasive blasting, involves propelling fine particles or abrasives at high speeds to clean or etch a surface. It is a potent method for removing tough coatings, rust, and imperfections. The abrasive material, such as sand, grit, or garnet, is propelled using compressed air, creating a force that can quickly strip surfaces. Sandblasting is commonly used in shipyards, automotive restoration, and architectural renovation.
Shotblasting – for when precision is key
Shot blasting employs centrifugal force to propel small steel balls, known as shots, onto a surface. This method is highly precise and leaves a consistent profile on the surface. It is frequently used for preparing metal surfaces for painting, as well as cleaning and enhancing concrete surfaces. Shot blasting is also employed in industries like aerospace and foundries.
Wet Blasting – easy does it
Wet blasting, as the name suggests, introduces water into the blasting process, reducing dust and friction. The mixture of water and abrasive media results in a gentle yet effective cleaning action. Wet blasting is an excellent choice for delicate surfaces that require a careful touch, such as monuments, sculptures, and fragile machinery parts.
To prep or not to prep?
