A Guide to Concrete Floor Resurfacing and Refinishing

Often, commercial concrete flooring gives the first impression of a business or property. However, pollutants, moisture, and other hazards can penetrate the concrete and, over time, cause reduced structural integrity and a weathered appearance.

Some concrete repairs relate to appearance (stained or discolored concrete), while others correct safety hazards like flooring unevenness or large cracks. Cleanstart Concrete & Coating can restore your concrete floor’s visual appeal and integrity and provide lasting quality. We offer a low-cost, beautiful, durable alternative to new or tired concrete. 

Our commercial concrete repair, resurfacing, and finishing services include

Surface preparation is a critical first step of any concrete flooring project. Hard Impact and heavy weight on concrete can cause cracks, divots, pockmarks, and holes. If the concrete hasn’t been sealed or finished, it can become stained by spilled material or an accumulation of dirt and grime. Making concrete sound enough for epoxy coatings will generally mean

  • Patching small holes, pockmarks, and divots 
  • Repairing cracks 
  • Rebuilding damaged or missing sections of concrete 
  • Grinding concrete surfaces 

Concrete Grinding and Polishing

The process of grinding and polishing smooths rough concrete to reveal a smooth and shiny surface. It requires using heavy-duty concrete grinding machines and diamond-impregnated segments or discs, which resemble durable sandpaper.  All coatings, stains, residues like mastic or glues, and surface cracks are removed along with the top layer of concrete. Concrete can be ground either wet or dry. Many businesses prefer wet applications to prevent concrete dust from getting everywhere. 

The benefits of concrete grinding include

  • Rebuild concrete surfaces. Removes all inconsistencies and imperfections, resulting in a usable and smooth surface.
  • Remove dirt, paint, or mastic—the best way to eliminate different remnants left on the concrete.
  • Create a smooth surface—floor prep is critical in the longevity of a new covering option.

Polishing uses the same concrete grinder but with higher-grit diamond tooling attached to it. Polishing usually begins with around a 100-grit to 200-grit diamond and finishes with an 800-grit or 1500-grit diamond.  The final ‘polishing’ steps utilize less aggressive diamond tools and progressively increase the reflectivity of the concrete surface. The number of polishing steps is dependent on the desired level of reflectivity.  

Compared to traditional floor coverings like tile, carpet, or vinyl, there are many advantages to polished concrete, such as

  • Low maintenance
  • A permanent finish – no reapplications required
  • Durable surface that’s scratch- and slip-resistant
  • No moisture-related cracking or peeling
  • Odorless, non-flammable, and non-toxic

Floor Coating Systems 

The risk of damaging your concrete floor can be substantially minimized by applying the right protective coating. Epoxy, polyurethane, and polyaspartic compounds are some of the most popular fluid-applied floor coatings. They penetrate the surface and provide a smooth, sturdy, protective covering.

Sealer or Coating?

A concrete sealer may be all you need if you’re looking to give an outdoor patio or driveway some essential protection or have an interior space that doesn’t have to withstand much abuse. But, if you need serious protection for an industrial or commercial floor regularly exposed to chemicals, heavy traffic, moisture, or other potential causes of damage, you’ll be better off with an epoxy floor coating; the best application for
