As we’ve discussed in this blog series, polished concrete flooring is a popular choice for commercial and industrial spaces. Renowned for its durability, aesthetic appeal, and low maintenance requirements, achieving the perfect polished concrete floor involves a meticulous installation process that requires specialized techniques and equipment. In this guide, we'll provide an overview of the key phases of the installation process, from grinding and honing to applying dyes or stains, polishing, and sealing.
Polished concrete creates a sleek and professional look for your space by grinding and polishing to a smooth finish. This process utilizes specialized machinery and diamond abrasives to transform the surface of the concrete. Let's delve into the key phases of the installation process to understand how polished concrete floors are achieved.
Grinding the Concrete
The first step in the installation process is grinding the concrete surface. This involves using coarse diamond-abrasive discs to remove imperfections and open pores in the concrete to accept polishing. The grinding process begins with more aggressive grits, such as 16 or 20 grit, for bulk concrete removal and exposing aggregates.
Contractors then progress through progressively finer grits, such as 30/35 grit for initial heavy grinding, 60/80 grit for smoothing and preparing the surface, and so on, until achieving the desired level of polish. Proper grinding is crucial for opening the concrete surface to accept the polishing process and achieve the desired finish.
Applying Dyes or Stains
After the initial grind, the optional coloring step involves applying liquid dyes or acid stains to the concrete surface for desired coloring effects. This step offers the opportunity to create unique designs and patterns by using multiple colors or techniques.
Polishing the Concrete
Once the concrete surface is adequately prepared, the polishing process begins. This involves using fine-grit diamond abrasives to hone and polish the concrete to the desired level of sheen, whether matte, satin, or glossy. Polishing typically starts with a coarser grit to smooth the surface and transitions to very fine grits for the final polish. Depending on the project requirements, contractors may choose between wet and dry polishing methods.
Sealing and Protecting
Finally, sealers are applied to protect and enhance the polished concrete floor. Impregnating sealers penetrate the concrete to provide protection from stains and enhance the shine, while topical sealers offer additional stain protection. Proper cleaning techniques are essential to maintaining the polished concrete floor's appearance and longevity.
Proper Tools and Techniques Needed for Quality Results
Achieving quality results in polished concrete flooring requires the use of proper tools and techniques. Contractors utilize grinders, edgers, burnishers, auto scrubbers, diamond polishing pads, sealers/densifiers, dyes & stains, joint fillers, ride-on trowels, shop vacuums, and protective gear to ensure a smooth and polished finish.
In conclusion, installing polished concrete flooring involves a comprehensive process that requires attention to detail and expertise. By understanding the key phases of the installation process, from grinding and polishing to sealing and protecting, you can ensure the successful implementation of durable and beautiful polished concrete floors in your commercial or industrial space.
