What is Planing?

Planing machines (sometimes referred to as Scarifiers) are designed to be connected to an industrial vacuum.

How it works

A drum, which has flails or picks attached to it, rotates at high speed within the body of the machine and ‘cuts’ down into the surface to create the profile.


There are different shapes and sizes of flails and picks available for specific tasks and they can be arranged on the drum in configurations for light cleaning applications through to heavy duty grooving.

View our Guide to Planing Flails.

The type and size of the planing machine, machine speed, type of drum and the nature and hardness of the surface being prepared will determine the profile and cleaning/texturing operation achievable.

The drum needs to be lowered carefully and slowly, using the two lowering devices, until it makes contact with the surface and the level of cut maintained to ensure an even profile.


Planing creates a more profiled, ‘rippled’ finish than other surface preparation techniques and may not be suitable for e.g. a final resin floor finish. Hard compositions may create a problem for smaller planers as there is not enough weight to cut into the surface.


When to use it

Typical applications include:

  • Removal of high build coatings and multiple layers in excess of 1mm in thickness, such as failed resins or screeds.
  • Thermoplastic line removal
  • Reducing tamped surfaces and levels up to 10mm
  • Rust removal on metal surfaces
  • Etching concrete and asphalt
  • Removing ice from cold stores
