Wet Blasting simply means that a “wet ring” apparatus is secured to the end of the blast nozzle, with water flowing from the wet ring into a stream of high pressure air and abrasive. Typically been used as a means to control dust generated from abrasive blasting, Wet Blasting permits little control over water flow and air pressure, which can cause issues in the finished product.Wet Blasting affects surfaces by:
Leaving surfaces drenched in water,
Leaving abrasive stuck to surfaces,
Negatively impacting operator vision by encrusting face shields with slurry buildup (decreasing productivity and precision),
Leaving a surface with a profile that abrasive sticks to.
Leaving a thin film due to imprecise inhibitor concentration at application.
Embedding water and impurities in surfaces due to the brute force of high pressure.
Vapor Blasting achieves better results because it relies on a combination of low pressure and increased mass (vapor encapsulated grit) to produce force. This process:
Prevents richochet and embedding of grit particles in surfaces.
Dramatically reduces abrasive and water consumption to prevent abrasive sticking to surfaces and face shields.
Mixes inhibitors and/or salt removes in the water tank for consistent, precise application.
Dries quickly, as vapor/mist does not drench surfaces.
Less kickback and 'set and forget' controls allow greater control over blast pressure.
Allows instant 'switch to rinse' to ensure no impurities or grit remain on surface during or after blast clean operations.
