Concrete Countertops: Achieving a Quality Finish

 Versatility, malleability and uniqueness of concrete are only a few alluring characteristics.  But it’s the durability and longevity of concrete countertops that have given the surfacing product a place among timeless materials such as marble and granite.  For concrete countertops to join ranks with natural and engineered stone surfaces, a high quality professional finish is critical and only achieved with the right tools.


Concrete Diamond Tools for Concrete Countertops

Concrete is a complex material. Various concrete mixes, local aggregates and a multitude of additives can drastically change the density, texture and quality of a concrete countertop. These varying attributes make concrete different from natural stones.  Granite diamond tools are often too hard and scratch concrete surfaces.  While diamond tools for marble are too soft and will wear prematurely. We always suggest using concrete diamond tools for concrete surfaces.

Tools For Edge Work: Adding Style

The edge design gives style and character to the concrete surface.  Sintered, electroplated or vacuum brazed diamond tools easily bevel and sculpt the edges by gradually grinding away material.  Edging countertops requires precision and finesse to produce elegant curves and even bevels.

Tools for Surface Grinding: Laying the Foundation

Surface grinding tools are designed to remove any inconsistencies or unevenness on the surface of the slab.  They can also be used to expose underlying aggregates producing a more textured looking surface.  Surface grinding tools are often run between 50 and 200 grit depending on how much material needs to be removed.  Surface grinding is an essential first step preceding the polishing phase.  A uniformly ground surface lays the foundation for a lasting finish.

 Rigid Rubber Backplate

  • A popular backplate that is rigid, but supple enough to ride over the surface without gauging or leaving marks
  • Add weight and stability to hand-held grinders

Tools For Polishing: Refining the Surface

Polishing is the final phase of the process.  Depending on how many steps used, a matte or gloss finish can be achieved.  The polishing steps typically begin at 400 grit and can go all the way up to 3000 grit for a highly reflective surface.  The image below is a great example of a perfectly polished concrete surface.
