When you think of concrete floors, you might imagine those dull gray slabs in deserted warehouse spaces or those seen in home improvement stores. Cold and unappealing, concrete floors serve their intended purpose but do nothing to beautify their surroundings.
However, polished concrete floors offer a unlimited variety of colors, finishes, luster, styles, designs and textures to both home and business owners. These flooring systems are the fastest growing trend in today’s market and are becoming a highly sought after feature in many commercial and residential settings.
But what are the factors that cause the fluctuation in prices between different slabs and contractors? There are several variables that a reputable concrete flooring contractor will need to evaluate as they evaluate your concrete flooring project. Some of the most important factors affecting the cost of polished concrete are:
Condition of the concrete
If the existing concrete slab is damaged, cracked or contains many dips and holes, additional products and labor will need to be provided to properly repair and repair these imperfections. There are many different products designed for concrete repair and it is important to hire a contractor who understands the different materials needed for your project.
Products designed for crack repair, for example, may not be suitable for use in holes or pits. Joints designed for pinhole size imperfections, again, will not be suitable for nickel or quarter size imperfections. As with all trades, more skills and knowledge are needed than initially appears.
Depending on the size of your project, extensive repair work can add € 1.50 to € 6.00 per square meter to the overall cost.
If an existing concrete floor is in very bad condition, it may be necessary to resurface or apply a concrete coating. Slabs that are uneven and with many bumps and deep elevation changes will not offer a suitable surface for polishers to operate on and leave your project unable to polish.
If you are determined to have the look of polished concrete in your space, this may be what is needed. Depending on the size of the project, the need for concrete surface refurbishment can add between € 12.00 and € 30.00 per square meter to the overall cost of the project.
The desired level of polish
There are different levels of sheen and brilliance that can be achieved with a polished concrete floor. For industrial halls or distribution centers, a 200 or 400 grit polished concrete finish is generally satisfactory. These finishes leave a matte or semi-gloss finish for spaces, but achieve the goal of providing a seamless, sealed floor for end users.
For other spaces, such as retail stores, showrooms or malls, an 800 or 1500 grit finish is usually satisfactory. These types of finishes leave customers with a fully glossy and reflective floor.
As a general rule, the more polishing you want for your space, the higher the cost as it requires additional time and the use of additional diamond tools for proper installation. Depending on the square footage of your space, each polish level you wish to include will cost between € 1.00 and € 2.20 per square meter.
The dimensions and layout of the floor
The location of the area you need to polish is also an important factor that flooring contractors need to consider when appraising your project.
Due to the processes involved in polishing and sanding of the concrete floor, larger floors to sometimes they are less expensive to prepare than the smaller ones due to the level of difficulty and accessibility. If the areas are to be polished by hand, installation will take considerably longer than it can be done by large industrial polishers.
Furthermore, the logistical circumstances of your space also play an important role in the price. Ground floor installations will generally be cheaper than polished concrete installations in the A.
