FREQUENTLY ASKED QUESTIONS

Why water when abrasive blasting has been around forever?

Several reasons, including Environmental, Health of employees, and an overall better finished product. Not only does UHP Water blasting surface prep provide a cleaner, even enhanced, original profile, it also removes contaminants such as chlorides, oil, grease, and chemicals. Conventional abrasive blasting creates a new profile, while removing not only rust and coatings, but also mils of good material to create the new profile. It can also leave behind unwanted material in crevices, instead of a clean, enhanced profile which leads to a better performing coating application.

Isn’t UHP Water blasting dangerous?

No, it is much safer than other forms of blasting! Due to the safety features built into our UHP equipment, such as dual triggers on hand lances, burst shield on hoses, internal pump “kick outs”, as well as lower body metatarsal protection provided on every job, UHP Water blasting is very safe. Proper training is mandatory prior to anyone using this equipment, which is done “in-house” with our certified trainer. We also have the ability to use our HydroCat Robotics system, which provides a remote solution for areas where conventional blasting would require multiple devices for safe operation.

Doesn’t UHP Water blasting cost more than using conventional abrasive services?

When total project cost is compared, UHP Water blasting typically will be much more cost effective. Since water blasting does not create a dust cloud, other trades can continue to work on your project simultaneously during surface prep and coatings operations. This creates a much more efficient use of time and money. The customer will also not have the cost of purchasing, transporting, and disposing of the abrasive product, cleanup equipment (vacuums), support equipment (additional air compressors), as well as a reduced amount of manpower used during operations.

What happens with the used water, or does it need to be disposed of like abrasives?

Most surface prep jobs require the water to go through a simple filtration process, after which time it can be tested and approved for normal discharge. Innovative Surface Prep even has a process for treating water after Lead based paint removal, call our Aqua Pure system. Once filtered through this system, many of our customers have been able to, after testing, approve to release the used water into the normal waste stream with no disposal other than paint chips. In the event a customer decides to dispose of the water as waste, it will still be a considerably smaller amount of water, as compared to disposal if abrasives were used. Waste volume is typically reduced 25:1, and disposal cost is normally reduced by a factor of 10!

Is Ultra-High-Pressure Water blasting the same as pressure washing?

No, UHP water blasting uses 20,000 to 55,000 psi water pressure to achieve its work. Normal pressure washing uses 1,000 to 5,000 psi water pressure. There is a massive difference in the power of the water and the final surface profile.
