What CSP measures
The surface profile describes the relief of concrete once prepared. It is read by comparing the surface with the moulded ICRI profile chips, numbered 1 to 10.

- Wheel plate CSP 1-4
- Roller plate CSP 3-6
- Chipping CSP 7-10
The CSP (Concrete Surface Profile) measures the roughness of concrete before a coating is applied. The ICRI 310.2R-2013 standard defines 10 profiles, from CSP 1, nearly flat, to CSP 10, very rough, with an amplitude above about 6 mm (1/4 in). A rotary bush hammer reaches CSP 6 at most: beyond that, you have to chip. This page presents the chart and names the Sept Tools machine for each level.

Bouchardeuse Fouine
The Fouine bush hammer has been developed with our brushless motors (low noise, low vibration, extended service life and waterproof) for renovation, construction, demolition, asbestos removal and dismantling. It handles your bush hammering tasks on render, resin, bituminous coatings and more. This bush hammer is compatible with our range of ergonomic trolleys, enabling overhead bush hammering. This machine must be used with an electronic speed controller IP65 and an industrial vacuum with a LONGOPAC bag.
Bouchardeuse Potam
The Potam bush hammer has been developed with our brushless motors (low noise, low vibration, extended service life and waterproof) for renovation, construction, demolition, asbestos removal and dismantling. It handles your bush hammering tasks on render, resin, bituminous coatings and more. This bush hammer is compatible with various ergonomic tools from our range, enabling wall bush hammering. This machine must be used with an electronic speed controller IP65 and an industrial vacuum with a LONGOPAC bag.
Burineur Plafond
Chipping hammer specifically designed for overhead work at height.

The chart
Understanding CSP in four points
Ten CSP levels
The higher the number, the more pronounced the relief. The standard describes CSP 10 as very rough, with an amplitude above about 6 mm (1/4 in).
CSP 1 to CSP 6: bush hammering
A rotary bush hammer reaches CSP 6 at most. The wheel plate (ref. PE102135) covers CSP 1 to 4, the roller plate (ref. PE102134) covers CSP 3 to 6.
Beyond CSP 6: chipping
Beyond CSP 6 a bush hammer is no longer enough: you have to chip with the overhead chipping hammer, in pneumatic (ref. ENS103398) or electric (ref. ENS103329) version.
Choosing
Which profile for which coating?
Epoxy, polyurethane and poured floors
The coating data sheet sets the required CSP: it is the reference, not a general value. Once the level is known, the chart gives the tool: wheel or roller plate up to CSP 6, chipping beyond.
Repair mortars and concrete overlays
The repair product also states the profile it needs on its data sheet. A more pronounced relief calls for a more aggressive tool: the roller plate goes higher than the wheel plate.
Decorative bush-hammered finish
The look is chosen by eye, by comparing with the profile chips. The wheel plate (ref. PE102135) covers CSP 1 to 4, the roller plate (ref. PE102134) CSP 3 to 6.
Check before application
Compare the surface with the ICRI profile chips under the same lighting, then record the level read before applying the coating. If it differs from the data sheet, redo the pass with the right plate.
Frequently asked questions
Your questions, answered
What is the CSP of a concrete surface?
CSP (Concrete Surface Profile) is a roughness scale defined by ICRI in guideline 310.2R-2013. It ranks the relief of prepared concrete from 1 (nearly flat) to 10 (very rough), so the applicator and the coating maker talk about the same level.
How many CSP levels are there?
Can you get a CSP 9 with a bush hammer?
No. A rotary bush hammer reaches CSP 6 at most, whatever the plate: wheel plate CSP 1 to 4, roller plate CSP 3 to 6. For CSP 7 and above, you have to chip with the overhead chipping hammer, in pneumatic (ref. ENS103398) or electric (ref. ENS103329) version.
Wheel plate or roller plate: which one to choose?
The wheel plate (ref. PE102135) covers CSP 1 to 4. The roller plate (ref. PE102134) covers CSP 3 to 6. For CSP 5 or 6, only the roller plate will do. See the Sept Tools bush hammer plates.
How do I find the CSP my coating requires?
It is in the coating data sheet (resin, mortar, waterproofing) or in the job specification. Sept Tools does not set that value: the chart helps you pick the tool that reaches the level asked for.
Which Sept Tools machines prepare CSP 1 to 6?
The Fouine (ref. BOU103607) and Potam (ref. BOU102130) bush hammers, fitted with a wheel or roller plate, with dust captured at the source. For an overview of the techniques, see concrete surface preparation.
How do I check the CSP reached on site?
By comparing the surface with the ICRI profile chips under the same lighting, before the coating goes on. The reading is visual and tactile; record the level in the job file.
