Concrete Polishing

Concrete Polishing

Why a Polished Concrete Floor?

Your most cost effective option when you consider the minimal maintenance costs involved of nearly ANY flooring type. This is now the go-to option for high end lofts, retail stores, & restaurants. Several dozen color choices and affordable low shine options are possible.

What is it and how do we do it:

We first grind off your concrete surface to open up the pores for our densifier application. This strengthens your concrete by means of a chemical reaction that creates a densely bonded crystal structure in the top surface layer. Next, we hone the surface smooth to give you an easy to clean glossy surface. Process is completed by heat bonding and curing an industrial protective coating into the polish for maximal chemical and abrasion resistance.

See the FAQ on polishing below to learn of it's pros and cons.

Frequently Asked Questions

  • Where should you NOT install a polished concrete floor?

    A garage/shop where there is potential for prolonged exposure to oils, brake, and transmission fluids. Outside and wet areas where water can sit on the floor for long periods of time. Commercial kitchens.

  • Are epoxy floors slippery? Polished concrete?

    They are not normally, but when wet with water or oil they can be. All the flooring solutions we provide conform to OSHA coefficient of friction specifications for floors. For specific flooring options like urethane or polyaspartic clear coats we include small anti-slip aggregates into the clear coat mix. This consists of an extremely hard material (aluminum-oxide) that actually helps strengthen your floor as well as give you traction. If you'd like additional anti-slip properties in your floor, like is common for public bathrooms, kitchens, and workshops, we can provide you with one of our common epoxy aggregate mix option.

  • Which of your flooring options are suitable for persons suffering allergies or asthma?

    Polished Concrete, Concrete Stains, and Epoxies are all excellent choices. They do not support the growth of molds, pollens, or dust mites. If you have a kitchen or laboratory project in mind let us know, we have numerous products that are specifically FDA approved for these applications!

  • Are concrete polishes and stains environmentally friendly?

    Absolutely! With polishing, the chemicals used to strengthen your existing concrete are extremely safe. There is no waste or material that eventually goes bad and needs to be thrown out and replaced, you're just using your existing floor to it's full potential! We also do not use acid based stains and so there is no harmful waste involved in our concrete staining/dying process.

    You may also qualify for LEED points on your project by choosing a polished concrete floor.

  • Can your concrete flooring options save me lighting or cooling expenses?

    Yes, when you choose a highly polished concrete floor or a bright colored epoxy, the lighting in your room goes a lot further, reflecting off the floor and helping to illuminate your space. In the summer you can also save on cooling costs.

  • What are my options regarding colors?

    Contact us for color charts and design suggestions. A molted one or two color design pattern is very popular. You can have company logos, names, symbols, football teams dyed onto your floor. We can make you a variety of patterns including checkered, diamond, wavy lines, symbols, or colored pathways. If you have a design in mind we can work with you to put that down on your floor.

  • What is a polished concrete floor?

    A polished concrete floor is a concrete floor that has been honed smooth and undergone a strengthening densification reaction. The densification process is a transformative chemical reaction which produces a dense crystalline lattice in the top layer of your concrete. This increases your floors resistance to the following: Abrasion, impact, chemicals, stains, chipping, pitting, erosion. It makes your concrete less porous while increasing it's density, sheer strength, and tensile strength. To top off this we apply a silane based clear coat that we melt into the floor for added chemical and stain resistance. This process creates a surface that can still transmit moisture vapor from inside your concrete floor (a good thing), while making the surface too dense to easily transfer liquid/chemical stains. The polar bond in most common chemical/ liquid stains remains intact, simply beading and pooling on the concrete surface, unable to penetrate the sealer or your concrete's dense crystal filled pores.

     

  • What are my concrete floor options?

    You can do a stain and clear coat, an epoxy and clear coat, or a polish. Each has it's advantages and disadvantages, as well as unique options to suite your needs and application.

     

  • What are some cons to polished concrete floors?

    Not all floors are suitable for polishing, if your concrete slab has many large cracks or holes that you'd like patched, these patches will stick out. If your concrete floor is very uneven or wavy a polish may bring these imperfections out. The price can be relatively high for a very high gloss finish compared to stain & seals or one colored epoxies. Polished concrete floors can be susceptible to staining by certain chemicals, especially strong acids or bases and may not be suitable for laboratories or workplaces handling them. Negligence in cleaning up spilled stains, chemicals, or hard water, will likely leave a stain if left sitting on the polished floor too long. Polished concrete floors are also unsuitable for commercial kitchens exposed to high levels of grease which will create a slippery surface. Here an epoxy floor with aggregate is more appropriate. Give us a call and we can help you pick the most suitable floor options.

  • What do I do with my baseboards?

    You can leave these on if absolutely necessary but realistically, you should remove these for any kind of flooring work your considering; concrete or otherwise. We can do this for you if you like.

    The details: While we have done plenty of work without removing them, it's not advised, and it will cost you more for us to have to carefully work on your concrete floor without doing too much damage to them. If you insist on leaving your floor boards on while we work, it should be still noted that they will inevitably get nicked, scratched, damaged, and dinged in places. Our tools have to be very powerful to grind concrete floors and your option is to either have unfinished edges or for us to try to get right up against them with 8,000 rpm hand grinders spinning a diamond embedded metal alloy disk. If you're getting an epoxy done, your baseboards will be partially embedded in the epoxy floor, this is especially the case for a reflective/metallic epoxy floor that has a thick build. With concrete floor polishing, the chances of damaging them goes up as we have to make numerous passes along your edges with ever finer polishing grits.

  • Do you offer a warranty and what does it cover?

    Yes, a one year warranty comes standard on all of our workmanship. If you'd like an extended warranty we would be gland to oblige you. We don't take shortcuts in our prep work or materials and so are glad to offer you written reassurances on our products and services.

  • What are my options for the control joints with a Polished Concrete Floor or Stain & Seal?
    1. Leave them as is. A very common option, but dirt & debris get stuck in there making cleaning difficult.

    2. Fill them with a elastomeric polyurea compound that will stretch and contract as your concrete moves. This will also help protect your concrete at the joint lines. It eliminates a blunt impact by wheels and dragging objects. It also makes your floors far easier to clean. Not to mention safe for high heels, roller blades, pogo sticks, and the like not getting stuck and preventing a potential tripping hazard.

  • What is the process for installing a polished concrete floor?

    We start our the process by exposing your concrete floor's inner surface layer using high end concrete grinders equipt with diamond embeded bits. We use HEPA filtered dust extractors to maintain a clean environment while we work. The next step is to apply a top end (Colloquial or Lithium based) densifier to your concrete to initiate the hardening and strengthening chemical reaction in your floor. Next, we carefully hone a shine into your floor by using ever finer diamonds to achieve your desired level of glossiness. It is this process that separates the experts from the amateurs in this industry, as it requires hitting your concrete floor from multiple angles at just the right speed with just the right tool, set at the proper power level and keeping a close eye on your floor to make sure that no spots are missed or neglected. Finally, we melt an industrial grade protective coating into your floor with a heavy duty high speed burnisher. This process enables the guard layer (a silane based polymer) to form a strong covalent bond with your polished concrete floor. This coating will act as a wear surface that will prolong your floors shine and strength.

     

  • How do you recommend I maintain my polished concrete floor?

    Because a polished concrete floor is so durable, it requires less maintenance than nearly any other flooring choice. Nonetheless, you should try to keep your floor free of dirt and debris that can slowly wear down the smooth surface. Periodically it's recommended to re-apply a protective coating we refer to as a guard. Re-application timing will depend on your usage. We can provide you with a maintenance schedule, but generally if you're a moderately busy retail store, once every six months should suffice. For residential usage, a year or more is typical. It can be easily applied with a micro-fiber mop. We also offer a maintenance plan which absolves you from worrying about when to re-apply and we use a more industrial burnish activated coating.

  • What is the cost of a polished concrete floor?

    For the most part price is determined by how shiny you want your polished concrete floor to be. Other big determinants are how much repair work you want done on your concrete. Whether you want to fill in your control joints or not. If you're getting a color with your polish or not. If we can get our 1,000 lb. grinding machines into your space and whether you have adequate power supply or we have to use a generator. If you want us to work overnight on a rush schedule through weekends or holidays. Lesser factors include: How far away from our shop you're located.How much work you're having done. Some discounts are possible too: If you're paying by cash or check, are an existing customer, or served in the military. All these factors have to be calculated and more to give you a final price. We have a civil and mechanical engineer come out to your home or business, assess the condition of your floor, and provide you with a free estimate. We'll provide you with many prices and options within 24 hours of after seeing your concrete floor.

  • How long do I have to wait after a new slab is poured to finish it with epoxies, stains, or a polish?

    28 days is recommended for all of the above. If you're getting a new slab poured and are thinking of using our services to finish your concrete floor, please give us a call first, we can provide you with some suggestions regarding the concrete mix and curing additives; especially if going with a polish! Some non-retarding concrete curing additives can increase the cost of your polish.

  • How do I clean my polished floor?

    You should use a ph neutral cleaner such as 'Simple Green' with a micro-fiber mop to clean up chemical spills. You would follow that up with plain water and finally dry off your concrete floor. If your floor is just a bit dirty or dusty, you can simply use a dry micro-fiber mop.

  • Do you offer maintenance plans for polished concrete floors?

    Yes, we will assess your floor usage and contact you at the appropriate times to schedule a cleaning and protective coating application. We will at those times examine your floor and tailor our schedule to meet you and your floors requirements. We would use a more industrial coating that requires high pressure and high speed burnishing. This product literally melts into your polished concrete floor providing you with superior protection, longevity, and less frequent maintenance. We provide our customers with a maintenance schedule upon completion of your concrete floor polish. Give us a call and we can help guide you with your polished concrete floor maintenance program.
