Graco Grindlazer vs SMITH Surface Preparator Comparison Chart

Graco GRINDlazer vs. SMITH SPS Series


The following is a comparison between the SMITH Surface Preparators (SPS8, SPS10 and EZOFF SPS10) vs. the Graco GRINDlazer.

The Graco model was first introduced January 22, 2010. The GRINDlazer is actually a much older-generation SMITH SPS10 Surface Preparator that was copied and given a new appearance. It includes a wrap-around frame, air-filled tires, and a lightweight paint machine handlebar frame, a quickly made coupler to lift and drop the grinder head to the surface when pushing forward with the main selling benefit being less vibration for the operator.screen-shot-2016-09-20-at-12-40-17-pm

Why Graco selected the name GRINDlazer is a mystery. Owners of pavement surfaces do not want their surfaces damaged when the stripe is removed. The name GRINDlazer implies surface grinding. While grinding may be best for surface-prep applications prior to striping, removing the stripe without micro-cracking or damaging the road requires a completely different process called rotary erasing, available here.  If you are looking for an easy, fast, and cost-effective scarifier, there are a variety of makes and models from which to choose.

Here is a video of the GRINDlazer machine in use. Notice how it can operate in only one direction. After 6 grinding passes, much of the paint (with deep scarring) remains. Photos of that same demonstration are available here.

Operators who purchased a GRINDlazer were happy with the look, but then noticed these issues when used:

  1. The Graco has limited applications – stripe removal only where there are no curbing obstructions. (due to the wrap-around framing limiting cut distance in the front, rear, and side of machines)
  2. The Graco pneumatic tires, located outside the cutting drum, prevents uniform removal (impossible to control depth of cut in low spots and the air-filled tires cause the cutting drum to bounce)
  3. The Graco will not remove in both forward and reverse direction (required for normal production)
  4. The Graco “insta-cut”depth setting is poorly designed  (breaks often and is expensive to maintain)
  5. The Graco requires 2X more passes to remove vs. a traditional scarifier, or 3X more than a SMITH

When selecting a scarifier, shaver or planer,  these are some of the important considerations:

  1. A balanced, weight over drum, no-bounce scarifier that can remove any type of materials on flat or uneven concrete or asphalt surfaces, using a variety of cutter options to achieve any removal finish from CSP 3 – CSP 10 with consistent depths and widths
  2. A removal system that removes in both the forward and backwards position with the cutting drum on the surface at all times, doubling production while getting very close to curbs or obstructions
  3. A portable, compact removal machine that can be pushed, pulled, and attached to a Sulky rider, with or without an up-cut carriage
  4. A machine that is built in the USA with at least 10 years best professional contractor service record selected, costing under $0.05/sf to operate and maintain
