Cold Weather Concrete Pouring for Polished Floors

As winter approaches, construction continues. Projects even with the best intentions of ‘getting closed up’ before winter sometimes still need concrete poured for floors that will be polished. When pouring concrete in freezing type conditions it’s important to keep them warm enough to allow the curing process to continue.

Why does concrete need a blanket?

Concrete is made with water and as you can guess in winter/freezing conditions the water will want to freeze. During the placement phase, concrete can be warmed up with hot water or have accelerators mixed in with the concrete that heats up the mixture, but once placed and the initial reaction dissipates the concrete is exposed to the conditions. Blanketing concrete is a common practice in which insulated blankets are placed over a fresh slab to keep the warmth of this initial reaction to stay longer, and keep the concrete processing through its typical 28-day curing cycle. If concrete freezes, the curing process stops, and will not start back up. This means that if concrete freezes early in its placement it won’t reach its full potential for hardness or durability.

Blankets and Polished Concrete Floors.

Blankets perform a structural purpose of keeping concrete hard, dense, and strong; but what about aesthetics? In polished and stained concrete flooring, the durability of the concrete is an advantage of concrete flooring, but we also need the new floor to be aesthetically pleasing. The drawback on blanketing concrete is that the insulated blankets keep all moisture from the curing process under the blanket, (really good for hard concrete) but this moisture then pools and follows the crinkles in the insulated blanket and can cause some unsightly marking, that becomes a permanent part of the concrete.

What to do?

Some initial steps by the placement contractor may help prevent blanket mark staining. These include:

  • Waiting as long as possible to blanket the concrete
  • If possible getting through the first night without the blankets
  • I have heard of a curing paper that can be used that will not leave markings. The process is to install this film- then the blankets. I am not aware of any successful projects or the added cost for this. Please email me if you have information on this.

If blanket marks do appear, there may be some remedies such as:

  • Grinding through the blankets marks. This will expose more aggregate in the concrete.
  • Using a dye or stain to accent the markings, adding to a ‘movement’ look (if desired)


  • Every concrete slab and condition will react differently to these markings.
  • An on-site sample can show how marks will affect final finish or remove marks.
  • The General Contractor, Owner, Architect, Concrete Contractor, and Concrete Polisher should all be involved in discussions around the blanket process, and how it might affect polishing process and pricing.

Polished Concrete in Commercial Bathrooms

Authentic polished concrete is known for its long term durability and is a popular choice in high-traffic consumer areas such as corridors, multi-purpose spaces and retail. Its durability lies in the inherent strength of the concrete as a building material plus a refined surface through mechanical polishing and an application of a sealing system. Polished concretes durability comes from the products used in the sealing process – a concrete densifier and a stain guard. These products penetrate into the open pore structure of the concrete leaving either a very thin film (just a few microns) to a non-visible surface film of the sealer. This allows the surface to be very abrasion resistant and eliminates the need of the stripping and waxing cycle. In addition, it will offer the ability to refine or re-polish the floor years into the future, giving the floor a brand new look at a much more affordable cost. This eliminates having to remove and replace another flooring material.

Polished concrete will age differently in bathrooms and areas prone to more spills. Polished concrete is still considered a porous surface and can be affected by standing water or high acidic liquids such as urine. These can etch the surface affecting the sealer and profiling the surface to continue to allow stains.

When designing this area you may want to create a sense of continuity by continuing the floor from hall or open space into the bathrooms.  When we work in this type of environment we recommend a urethane sealed concrete floor as opposed to a polished concrete floor. The urethane sealing system is a two-coat process of a water-based epoxy primer and high-wear catalyzed urethane topcoat. This topcoat can also utilize an anti-slip additive that will aid in slip resistance. This urethane sealing system, although very strong, does not have the same abrasion resistance you will see in a full polished concrete floor. Typically, stain resistance is more important in and area as a bathroom. The transition leading into the bathroom is typically completed at a saw joint leading into it and it can easily be hidden under the door with no need for a transition strip. To the general-purpose user of the area a difference in appearance is likely to go unnoticed.  The urethane sealer is compatible with natural colored, dyed, and reactive stain coloring methods as well. Unlike polishing, when using a urethane sealer, it is very important to check the relative humidity of the concrete.

An alternative choice would be to leave the bathrooms polished.  Should this option be chosen, additional maintenance or urinal pads may be required to keep the floor in a ‘like-new’ condition. You also can choose to leave the floor as is and allow the floor to develop a worn-patina look. Many restaurants and park departments allow this patina to develop.  You might notice should at a few older Chipotle’s they bring the polish directly into their restrooms.  However, most have since moved to a high-strength urethane mortar system with integral cove.

As in most facades of construction there are many options available. The final decision involves choosing the right floor, balancing client’s expectations, budget constraints and construction schedules.

When considering polished concrete or epoxy floor coatings as a flooring solution, clients may be concerned about the mess that may be left behind. This is a valid concern since clouds of dust commonly come to mind when thinking of concrete projects. The dust created through preparing, cutting and grinding concrete surfaces is unavoidable. It’s how we, at Dancer Concrete Design, control that dust that makes all the difference.

We think that dust control is a large part of a satisfactory project. To achieve this, we hook up our equipment to specialty vacuums created to handle concrete dust. These vacuums have purging systems that allow the vacuum to clean its filters of the fine concrete dust while continuing to perform. There are different vacuums used depending on the size and scope of each project.

Generally, our team creates less dust than other construction trades on a project. If a situation presents itself where the maximum dust control is necessary, we offer these additional options:

  • Dust control package: An extra team member is on-site throughout the grinding processes to vacuum all dust left behind by the main grinder.
  • Hanging extra tape and plastic: This is popular in industrial settings where intricate machines require the utmost protection, as well as in residential settings where entire rooms can be closed off during the grinding processes to prevent any dust from entering.
  • Implementing air scrubbers: Air scrubbers collect any loose dust that may have escaped into the air.
  • Vacuuming floors at the end of the project instead of using microfibers.

With all the dust control efforts, there is always a chance of small amounts of dust during a project. This can be simply from walking across the floor and getting dust stuck to footwear. We do recommend a thorough cleaning of your space when we leave the job site, but we reassure you that our best efforts will be taken to control concrete dust.

Simple Design

By Alexis Dancer

What is good design? What is great design? What makes the difference between a good design and a great design? A great design appears to be simple at its completion because of the organization, process, and planning put into the design at the onset. I do not know what said this first, but they were brilliant. Design is an ongoing planning process that is put into play to create a functional space. The point of the design process is to take a jumbled knot and to turn it into a clean, straight line with just a few curves to add interest. 

Great design appears to be simple, but simple is not a popular adjective for American interiors. Everywhere we look there is just more stuff. More information, more advertising, and more clutter in our minds as well as in our homes. As with the items that we obtain, a building can also become over-cluttered in terms of design elements. There is something to be said about simple spaces or spaces that are simply designed well. Simple and great designs look beautiful yet continue to serve their purpose.

To encourage simple design, let’s simplify our building materials. Concrete is an obvious choice as a building material for many different reasons: it can be molded and shaped to fit any mold, it can be poured for structural stability, and, in our modern world, it can now be polished to create a beautiful finished flooring material. Concrete can cover several square feet without needing a control joint or seam. Concrete can also be poured as an overlay for a uniquely seamless and clean look for a floor. This unique quality of concrete visually expands any space without obstructing the view to the rest of the interior elements. Concrete floors allow the interior to speak for itself. They appear to take nothing away from the design, yet add everything to it. Concrete floors can visually take up to 50 percent of a design, yet they seem to bow down to the rest of the space and let architectural elements and furniture speak for themselves.

Making a design simple may seem, well, simple. We may say, “Just don’t put anything in the room,” but a room is made for a purpose and for a certain function of work or life. So, for that reason we must add to the building shell. To decide how to design a space, let’s think about what Louis Sullivan said, “form follows function.” A space will be beautiful if it functions as it should. The beauty hides in the details. When a drawer closes with ease by way of soft-close glides, now that’s beauty. When a floor cleans up easy and looks great for years to come, that is also beautiful. Concrete is a simple building material that contributes to the structure of the building (the building’s function) as well as to the aesthetics of the finished space when it is polished. Partner all of these elements with concrete’s wide array of color stain options and polishing finish levels and you have one unique and well-designed building material option. Concrete can also save building owners from maintenance nightmares. Great design is more than just aesthetics, great design also takes maintenance, durability, and lifetime cost of materials into consideration.

Design is different than decorating in that, with design, we study the psychology, the function, and the importance of the spaces that we use. With decorating we simply build on to the aesthetics of a space or add to the base of the design sometimes beyond what is necessary for the space to function for our needs. Sometimes we think that we can enhance design through decoration, but the truth is that adding more clutter to a poorly designed space will add even more chaos. When elements in a space are kept simple and, at the same tines make sense to the function of the building, we can experience cohesive and easy living. By using concrete as a finish material, we can allow the rest of the interior to speak for itself and contribute to simple designs.
