CAPTIVE SHOT BLASTING PERTH
HAWK CFC has made the investment in shot-blasting equipment; this is a key factor that separates HAWK from the competition in WA.
Shot-Blasting is the most heavy-duty form of surface preparation on the market. It’s ability to strip concrete of its top layer, quickly and effortlessly, makes shot-blasting the superior form of surface preparation. The shot-blaster machine pushes small steel balls, (steel shot), through a closed circuit system and then recycles the steel shot to be used again. This process is done at high velocity removing contamination, coatings and laitance (soft concrete), to reveal a mechanical, concrete surface profile for superior bonding of future coatings or overlay systems. At HAWK CFC we control concrete dust by using state of the art, powerful dust collection systems, reducing clean-up and ultimately reducing downtime.

SHOT BLASTING CORRECT SURFACE PROFILE
Many, if not most, manufacturers recommend shot-blasting for preparing your substrate and even the the International Concrete Repair Institute (ICRI) have listed it as the superior form of surface preparation in comparison to diamond grinding, as it easily achieves a CSP3 Surface Profile. The concrete surface profile achieved through shot blasting creates a highly textured, keyed surface profile which increases the surface area and subsequently increases the bond of any material applied to it.
BENEFITS OF SHOT-BLASTING
Using shot blasting equipment is environmentally friendly because it eliminates the use of harsh chemicals that can cause damage to the surrounding habitat or people using the facility. When these machines are used by trained individuals, the rate of preparation production is hard to beat; surface-stripped patterns are accurate and consistent, meaning you get consistent adhesion throughout your floor. Having a meticulously patterned preparation has a great affect on the overall presentation of your finished floor.
WHAT TO CONSIDER
Shot-blasting is ideal when using a self-leveling resin or overlay as the resin will fill in any discrepancies in height over the expanse of the floor. In cases where a thinner roll-coat or other kinds of non-self-leveling coating is being applied, shot-blasting is not the most ideal solution and concrete grinding would be highly recommended. It is important to know which preparation technique to use for your job, as well as having skilled, passionate technicians to carry out the task. At HAWK CFC we have the equipment and trained, in house technicians to cater for all your preparation requirements.
