Hudson Concrete Polishing
Most people think of polished concrete as a hard surface with a shine. However, there are many options and unlimited design possibilities that can be customized depending on what you are looking for.
Most of the projects we work on in New York City are old cement surfaces. Many are uneven, damaged and cracked. Door jams and floor vents present their own set of height issues which need to be taken into consideration. Construction projects over the years have created issues with holes in the concrete surface from nails, screws, electric wires and plumbing. We carefully analyze all the solutions before presenting the options.
Problems can be repaired, but the reality is that a polished surface does not cover up blemishes. Blemishes in the floor can add to the design depending on what you are trying to achieve.
It’s important to know that when we polish old concrete, we don’t know the extent of the aggregate that was used when the floor was created years ago. Polishing starts with a grinding process that exposes the old stone in the cement. There is no way to know exactly what the outcome may be. No two floors are the same.
Concrete Overlays and Self Leveling
When we encounter a floor with a damaged uneven surface or with height issues at doorways, we’ll use a self leveling overlay. Self levelers as we call them, can be polished, sealed and burnished. We can color them by mixing color pigments to your exact specifications.
Technological improvements with products, equipment and installation techniques have transformed our capabilities. We can provide our clients with unlimited function and design solutions. It’s common to look at a completed project and think, “we just did that!”. It’s a little like being a sculpturer working on a flat horizontal surface.
We Are Floor Designers
Interior design usually starts with the floor and works upward. Flooring should not be an after thought. When we look at a space, we spend a considerable amount of time listening to what the owner, designer and architect have in mind for the interior design. Once we have a handle on the overall scheme, we can provide options.
Function and design are always two major considerations as well as price and completion time. If we polish an existing concrete floor , people can walk on the surface around us. If we are install a self leveler, no one can walk on the floor until 100% complete. It’s important for everyone involved to understand the processes. There is nothing worse than finishing a tough project and coming in the next day to find that someone walked on the project after we left leaving permanent footsteps. When concrete dries, that’s it. Put your hand in it and the next day you will have an imprint that lasts forever.
We’re passionate about our work. It’s painful to see footprints in our work. Not to mention that the owner is not to thrilled either.
Areas We Serve
Though we will travel to do a project, our core market is New York City and neighboring areas. Just manuvering around NYC is a specialty that has taken years to master.
Look around our site and call me with any questions. We’ll gladly take a look at your project and show you our portfolio to give you an idea of design possibilities. Paul Huneck (Owner) 718-482-0850.
We specialize in concrete polishing throughout NYC, New York and neighboring states, New Jersey and Connecticut, using the Husqvarna HiPERFLOOR system. View the 6 minute video below to learn about the step by step process.
The HiPERFLOOR system was developed by Husqvarna, an internationally known construction equipment designer and manufacturer. The process starts by grinding the existing surface similar in theory to sanding wood. We use a dustless high torque vacuum which virtually eliminates dust. The process uses coarse diamond blades followed by subsequent finer abrasive diamonds.
The grinding machine we use, made by Husqvarna, is an upright, walk behind machine. We grind the entire surface and eliminate all high spots in the floor. Each diamond blade we use produces finer , smoother concrete. For most projects we use 7-8 various blades. After approximately 4 levels of grinding and polishing we apply HiPERHARD, a liquid densifyer increasing the strength of the surface. The subsequent polishing levels are what produces depth and shine.
For decorative floors we can dye the concrete prior to application of the densifyer. Dyes are opaque producing a natural coloration of the cement floor.
Once the floor is complete it can be used immediately. There is no downtime waiting for anything to dry. Most of the floors we complete are single color, seamless surfaces (other than expansion joints). However using specialized tooling we can create unique patterns and designs with extraordinary results that will last indefinitely.
In addition to providing our New York City and Tri-state residential and commercial property clients with high performance architectural overlays and self leveling,we also provide concrete polishing services.
The system we use is called Hiperfloor, developed by Husqvarna, one of the worlds leading manufacturers of specialty construction equipment. This is a revolutionary method for grinding, treating and polishing concrete surfaces.
Not only does the result look excellent but the functional properties are greatly enhanced. Floors are low maintenance, cost effective with a gloss finish that can be adjusted from a matte finish to high shine.
The system uses a combination of liquid densifyers, which increase strength of the concrete floor, and diamond technology for grinding and polishing the surface.
The floor grinding process starts with coarse diamond resins followed by subsequent steps using finer grit levels until the appropriate level of polish is achieved. Midway through the process we apply Hiperhard, a liquid densifyer, making a durable surface stronger. The Hiperfloor system is odor free and relatively quiet. There are no coatings that delay the process enabling us to work around your schedule.
Color choices are varied. We can dye the concrete in your choice of colors or design with a result that can appear like marble or terrazzo.
We are based minutes from mid town New York City and service clients in the tri state area. We will travel for projects throughout the east coast when necessary.
Polished concrete is the process of grinding a cement floor with coarse diamond blades using subsequent levels of finer blades to achieve a durable, shiny surface almost like marble or terrazzo. The equipment used are heavy upright, walk behind machines like pictured above at The Husqvarna booth at the World of Concrete.
The process creates surface dust which is removed while grinding the floor with high torque vacuums. They eliminate airborne dust.
During the process which can include 7-8 various levels, a liquid densifyer is added to the surface. This liquid creates a chemical reaction with concrete tightening the pores, increasing the surface strength, providing more surface area to polish. The end result is a durable, easy to clean shiny floor.
There are variations of the shine. The process starts out with diamond blades ranging from 25-80 grit, followed by 100,200,400,800, 1500 and 3,000 grit levels. A matte finish might stop at 400 grit to the highest level shine at 3,000 grit.
As you can see in the photos above, a polished floor can be colored with stains and dyes. In some cases a floor will be sealed with a concrete sealer.
Overlays are not polished concrete though they are frequently considered part of the polished concrete family. Some overlays provide a similar look, but to the true polishing industry experts they are a completely different application. To view an overlay application click here.
This is a polished concrete floor we completed at an industrial facility in NYC on 27th Street and West Side Highway. The process is the Hiperfloor System developed by Husqvarna. We worked in conjunction with Grimshaw Archictects on the restoration of the cement surface which was in rough shape when we started.
The 100 year old, 12,000 square foot floor required a tremendous amount epoxy and adhesives ground off the surface before we could even start the restoration. It was slow going in the beginning due to horrible condition of the slab. Grinding and repair needed to be done simultaneously making our progress dredfully slow. We persevered and finally started seeing daylight.
Once we started grinding the surface we found an excellent concrete floor. As you can see in the photos we were able to deliver a highly polished surface in bright, usable shape. In fact, the flooring could have been used in a retail store once we were finished.
Our main focus is concrete floor polishing and self leveling cementitious overlays like in the photos here of projects in NY.
Virtually any concrete surface, no matter the condition can be restored, polished or resurfaced. The new surface will be extremely durable, non slip and decorative. In fact, even when slightly wet a polished surface still meets or exceeds OSHA recommended coefficient of friction levels.
To see the installation process of a self leveler installed click here to watch a video of a project we completed in a loft apartment in Brooklyn. This floor was about 3,000 square feet. Size does not matter. We can install from 1,000 – 100,000 square feet or larger.
The polished process is different. Each floor is different. Some floors require patch and crack repair before we start the grinding process. Like refinishing wood, we start with coarse blades followed by subsequent levels of finer blades. Mid way through the process we apply a liquid densifyer increasing the strength of cement while tightening the pores. The process gives us increased surface area to polish.
The result is a tough floor that wears well. The versatility of design options enable us to provide our clients with a broad range of utilitarian to designer surfaces.
