How to choose the polished concrete colours

Posted by on October 6, 2016 in Flooring and polishing, Home Bilding

Polished concrete is available in a variety of colours and finishes. Due to the wide range of designs in which they are available, they have become a common sight in showrooms, corporate offices, outdoor dining areas, restaurants and coffee shops.

Colour choices for polished concrete

Polished concrete generally shows many variations in aggregate exposure and colour. The aggregate may vary from polishing only the surface, boldly exposed or finely cut. Colour basically comes from three primary sources:

  • Dark or light grey concrete which has color mixed in it.
  • The staining of the surface with color before polishing.
  • The aggregate color.

Color can enhance the appearance of the concrete and also provides numerous design options. Colors may be used to make the concrete floor look unique as a standout feature in the interior or may be chosen in a way to blend with the overall décor. Colors can hide various types of imperfections in the concrete floor and hence make it look more appealing.

Concrete floors may be colored by using the following three methods:

Acid staining

Acid stains are waterborne mixtures of acid and metallic salts. These stains produce chemical reactions with the concrete. These stains generally result in bright, translucent colors which may present various hues. These colors being UV stable do not fade easily. The colors produced do not negatively impact the air quality as the acid mixture is devoid of Volatile Organic Compounds. The acid staining provides a color choice of three colors namely blue green, brown and black. The colored layers are thin and are generally protected with sealers which may require frequent reapplications. The process is time consuming and hence more expensive.

Solvent based dyes

In this option, fine color molecules are mixed with solvents. The mixture penetrates and colors the concentrate. In order to enhance the color coverage, multiple applications may be required. The process takes lesser time than the acid staining procedure and shows quick results. This option provides a number of vibrant colors which may be chosen. However, the colors used in this process tend to fade over a period of time and may require reapplication. They also fail to hide imperfections and the strong alcohol and acetone odors may impact the air quality indoors.

Water based colors

The water based colors are easy to apply. They are generally mixed with water. The mixture is then sprayed on the floor. Scrubbing is then done using a microfiber mop or broom to penetrate the color into the surface. Water based colors are available in numerous shades. Their ease of application makes them a less expensive option. These colors also provide an ecofriendly option as they are devoid of strong odors and hence do not affect the indoor air quality. These colors however may require sealers to penetrate and protect the color. In the absence of sealers, these colors may fade away. Since these colors do not possess UV stability, they often require periodic reapplications. The frequency of reapplications may depend on the exposure to bright indoor lights or sunlight. Now if it is plaster rendered on walls, this would go great with concrete polished floors too. For solid plaster rendering, we recommend Crown solid plaster Melbourne as the best service provider in Victoria.

Colors can effectively be used in residential and commercial structures to enhance their appearance. They are preferred in venues like stores, malls, galleries and showrooms that experience high visitor traffic.
