Surface Preparation
Abrasive Blasting
An abrasive blaster works on the principle of high pressure compressed air being used to force a mix of air and fine abrasive through a nozzle. The abrasive particles will quickly remove paint, rust, corrosion, dirt, and discoloration from many different types of surfaces. Just as there are many surfaces to be cleaned there are many different types of abrasive materials that can be used.

An important element of any coating project is surface preparation
When choosing the right abrasive for the job, the size, hardness, mass, sharpness break down rate and reclaim capabilities should be considered.
The most important element of any coating project is surface preparation. You need the surface roughness to achieve maximum bond strength of the coating system. Inadequate surface preparation is the major cause of all coating failures.
The following are a few common types of surface preparation operations:
- Abrasive Blasting
- Single Use & Recycle
- Media
- Wheelabrator
- Wet Abrasive
- Blasting
- Steel Shot
- Peening/Cleaning
- Sponge Jet Blasting
- Bicarbonate of Soda
- Blasting
- Power Tool Cleaning (SP3)
- Hand Tool Cleaning (SP2)
- Solvent Cleaning (SP1)
- Water Washing and
- Jetting
- Low-Pressure Water Cleaning (<5,000 psi)
- High-Pressure Water Cleaning (5,000 to 10,000 psi)
- High-Pressure Water Jetting (10,000 to 25,000 psi)
- Ultrahigh-Pressure Water Jetting (>25,000 psi)
