Surface Preparation

The most important step of any flooring application

Surface preparation is considered to be the most important step of any flooring application. Improper surface preparation could turn what seems to be a simple process into a lengthy difficult repair.


  1. Assess the Surface. Examine the surface and determine what type of conditions exist.
  2. Determine the Profile/End Result Desired. Determine the profile or the end result desired for the surface.
  3. Identify the Process. Based on the surface conditions and the desired end results, identify possible equipment/surface preparation methods.
  4. Test to Confirm. Perform a test patch to confirm selection.



The ShaveMaster™ is a specially designed floor machine that makes coatings removal and concrete corrections simple. It creates a series of evenly spaced grooves that can also be used to provide traction and reduce the risk of slips and falls.

The ShaveMaster™ uses diamond blades to create a precise pattern. Unlike scarifying or shot blasting, safety grooving leaves the floor structure intact and provides a long lasting, uniform appearance.

  • Prep surfaces
  • Lippage removal
  • Coatings removal
  • Curled joint repair:
    • Aggregate exposure
    • Improve floor flatness
    • Paint striping removal
    • Correct a poorly placed concrete slab
    • Remove spalled areas or failing slurry caps


Diamond grinding is typically used to level uneven pavement and to roughen surfaces for skid resistance. It has low dust levels, removes epoxies and urethanes but is slower than other methods. Some diamond grinders can also leave swirl marks in the slab if you’re overly aggressive.

Some of the advantages of a diamond ground pavements include:

  • Provides a smooth surface that is often as good or better than a new pavement
  • Enhances surface texture and friction and there is no evidence of deleterious effects
  • These improvements reduce the potential for small-vehicle hydroplaning
  • Does not significantly affect fatigue life of a pavement
  • Does not affect material durability unless the coarse aggregate is a soft stone subject to polishing
  • May be applied only where is needed, however, spot grinding is generally not usually recommended
  • Restoring smoothness to faulted or curled concrete highways Improve skid resistance
  • Level doorway entrances
  • Smooth driveway approaches


Concrete polishing is achieved by using heavy-duty polishing machines equipped with progressively finer grits of diamond-impregnated segments or disks (akin to sandpaper) are used to gradually grind down surfaces to the desired degree of shine and smoothness.

The process begins with the use of coarse diamond segments bonded in a metallic matrix. These segments are coarse enough to remove minor pits, blemishes, stains, or light coatings from the floor in preparation for final smoothing. Depending on the condition of the concrete, this initial rough grinding is generally a three- to four-step process.

Concrete polishing is a great solution to problem floor conditions such as moisture, chemicals or hard abuse.


Steel Shotblasting is the preferred method of mechanical preparation that cleans and profiles simultaneously. Shot Blasting strips thin coatings, removes contamination and laitance (soft concrete) to reveal a mechanical profile for improved bonding. This method is achieved by blasting a concrete surface with steel shot (small steel balls) at a high velocity. It is suitable for large and small areas. Shot Blasting delivers high production rates, dust free, dry and cost-effective. Excess shot must be swept-up after blasting and dust is recovered by a powerful dust collection system.
