Frequently Asked Questions

Some questions, we get asked alot!

Sandblasting costs vary depending on each application, but your typical overhead costs are either electricity or diesel/fuel to run your compressor, and your abrasive costs per job. The formula below can help you identify target costs.

A = Abrasive Consumption
B = Delivered cost of abrasive
C = Disposal of abrasive
D = Labour cost
E = Equipment cost
X = Blasting Speed in square foot/hour (or square meter/hour)

Your labour cost is your profit margin, and that is set by you!

Abrasive blasting is an efficient method of surface penetration. No other method of cleaning allows better control of the surface preparation or cleans the surface as thoroughly. By beginning with a screened abrasive, you control and obtain a consistent profile on the targeted surface. This clean, etched surface aids in adhesion and allows the coating to adhere onto the surface.

As an industry leader, Flowtech Blasting guarantees its shot blast machines against defects in material and workmanship for a period of 2 years from the date of purchase.

Yes! this is one of the easiest ways to remove rust from a surface!

Yes! Using a hard abrasive like garnet, or crushed glass at 100psi, chrome plating can be removed easily, although care must be attained so as not to damage the substrate material, using ultrafine abrasive is recommended.

Yes, used dry various media can be reused more than once, particularly abrasives such as steel shot, or glass bead, this is typical in blast room installations for production work, with the same process being repeated. Contaminants should be removed from abrasives prior to reuse.

Yes, to minimize the risk of warping thin materials such as car bodywork, blasting pressure should be set at the minimum to remove the coating only, used in wet mode to reduce heat distortion, an abrasive such as sodium bicarbonate is ideal for this application.

Yes! Wet or vapour abrasive blasting can be done safely in open areas, when dry blasting however the area should be contained to protect others from airborne dust.

Abrasive blasting is a process used for surface cleaning/preparation. A blasting media is propelled through a nozzle at low or high pressure with compressed air. Shot blasting works by propelling round materials known as shot media against a surface which in turn removes the contaminants of the surface and can improve its finish, the operator or machine holding the shot blasting gun/nozzle directs the flow of the shot media to clean the material surface.

Yes! Using a hard abrasive like garnet, or crushed glass blasting at around 100psi, galvanizing can be removed easily, care must be attained so as not to damage the substrate material, using ultrafine abrasive is recommended.
