SHOT BLASTING ON CONCRETE

Ideal for concrete surface preparation

Find everything you need in one place with our range of powerful shot blasters in different sizes for handling small jobs or tackling major projects in various concrete and asphalt applications. All our models offer manoeuvrability, precision and versatility. When connected to an appropriate dust extractor, they create an environment that is virtually free of dust and contaminants.

Concrete surface profiles (CSP)

The profile left behind on the surface when shot blasting depends on the size of the steel shot, the speed of the machine and the amount of steel shots you throw on the surface. With shot blasting you can achieve surface profiles levels 3-7 (set by ICRI – International concrete restoration institute). See the chart for more guidance.

          
Surface Profile  CSP-3 CSP-4 CSP-5  CSP-6 CSP-7 
 Method Heavy grinding
or very light shot blasting
Light shot blasting Medium shot blasting Medium / heavy shot
blasting or light scarifying
Heavy shot blasting or
medium scarifying
 Hardware To achieve CSP-3,
use a Husqvarna grinder with PCD tools
or use a Blastrac shot blaster with small
sized steel shot at maximum speed.
To achieve CSP-4,
use a Blastrac shot blaster with small /
medium sized steel shot at high speed.
To achieve CSP-5,
use a Blastrac shot blaster with medium
sized steel shot at medium speed
To achieve CSP-6,
use a Blastrac shot blaster with medium /
larged sized steel shot at medium speed or
a Blastrac scarifier at low depth
To achieve CSP-7,
use a Blastrac shot blaster with
large sized steel shot at low speed or a
Blastrac scarifier at medium depth.
