What is polished concrete floors?
Polished concrete is concrete that has been treated with a chemical densifier and ground with progressively finer grinding tools. The grinding tools are progressive grits of diamond grinding cup wheels and diamond polishing pads.
Can any concrete floor be polished?
Almost any concrete floor. Floors which are saturated with oil, or are in environments where they will constantly be exposed to acids, are probably not ideal for a polished concrete floor system. Whether new construction or a 100 year old slab, most concrete floors can benefit greatly from the aesthetic, durability and longevity of polishing.
At what point in the construction process should we schedule the work?
Ideally, you should contact Hapax prior to construction for a detailed list of items that drastically affect the concrete polishing process. This information will be made available upon request. Due to the difficulty of protecting a finished floor from damage by other trades; we prefer to come in after drywallers, plasterers, and tilers but prior to the installation of the kitchen cabinets, islands, toilets and baseboards, and final paint.
Is polishing concrete messy?
Mechanical, dry-grind polished concrete is pretty clean process. Grinding will create a slurry, and can get a bit messy. But with the dry-grind process, a vacuum system is used in conjunction with the grinder to contain 98% of the airborne particulates. The remainder of the dust is easily swept up. It also does not have the odor that is present from some coatings like epoxy or glues used in some other flooring applications.
How does the floor become so shiny?
Just as in traditional polished stone applications applied to marble and granite, the surface of the concrete floor is ground using progressively finer grits to smooth and seal the surface. Instead of having a pitted surface that refracts light, the light reflects from off of the floor – THAT is what creates the shine of the surface. It is not a product or the sealer that makes the floor shine. It is the concrete itself reflecting light.
How does the concrete need to be prepared?
The concrete must be cleaned with a commercial floor cleaner or buffer. Depending on surface condition certain degreasers or other floor cleaners may need to be used.
What kind of maintenance does a completed job require?
Polished concrete is one of the easiest system to maintain, and does not require aggressive cleaners or brushes to lift dirt away. The best daily maintenance is simply using a dust mop or mop and mild cleaner.
If polished concrete is used in a public building, an autoscrubber can be used with super soft brushes and a gentle cleaner designed for polished concrete to suspend dirt off the floor and squeegee it up.
What happens if the concrete gets chipped or gouged past the stain?
Chips and gouges are easily repaired and touched up with stain. We record what was used on your job for future reference in case of accidents. We will leave this information with you as requested.
What type of protection do you recommend using to protect the floor during construction?
When covering a floor, we recommend over lapping corrugated cardboard or rosin paper and taping to the cardboard or paper. Do not tape to the concrete; this leaves dark, blocky marks in the concrete, which are permanent. Some builders have placed 2 x 4 planks along the walls to weight the cardboard.
How soon can I use the floor after the polishing?
A polished concrete floor can be walked on during the grind and polish process. There is no “cure” time since it is a mechanical process. When the guard is applied, there is a 30-45 minute dry time.
Is a polished concrete floor slippery?
Just because polished concrete is shiny doesn’t mean it is slippery. Testing has shown that polished concrete usually meets or exceeds OSHA standards for slip resistance.
Is it ok for me to place rubber backed rugs or non-open skid weave matting or pads under my rugs?
No! It’s not recommended; doing so could result in permanent discoloration in the area’s they were placed due to trapped moisture/ vapors or sweating conditions.
How durable are these floors?
These floors should not be considered maintenance free. They will need to be kept clean and clear of any debris that may scratch the surface. For interior jobs you will have a clear wax, also called a wear coat that will need to be reapplied based on the traffic and wear of the floors.
