What Colour is Concrete: Exploring the Varieties

Concrete is no longer limited to a utilitarian grey hue. Today, there are a wide variety of concrete colour options available, allowing you to bring vibrance and personality to your projects. From driveways to tabletops, floors to patios, coloured concrete can transform any space. For more information, check out our Concreting Solutions in Townsville. In addition, if you’re thinking about upgrading your space, explore our guide on ‘How to Smooth Exposed Aggregate Concrete: Techniques and Tips’ for effective techniques and tips.

There are two main methods of colouring concrete: integral and topical. Integral colouring involves adding colour directly to the mixed concrete, resulting in an even and consistent hue. Topical colouring, on the other hand, involves applying colour after the concrete has been poured.

Concrete can be coloured using various means, including dyes, pigments, stains, and colour hardeners. Dyes are versatile and come in a wide range of colours. Pigments are added to the concrete mix before pouring, providing long-lasting colour. Stains can alter the tint or shade of concrete, while colour hardeners strengthen and intensify the surface hue, particularly for decorative and stamped concrete.

Choosing the right concrete colour requires consideration of the project type, surface condition, location, desired aesthetic, and budget. Consulting with experts can provide valuable guidance in selecting the perfect concrete colour.

Types of Concrete Colouring

When it comes to enhancing the aesthetic appeal of concrete, colouring plays a crucial role. There are two main methods of concrete colouring: integral colouring and topical colouring. Let’s explore each method in detail.

Integral Colouring

Integral colouring involves adding colour directly to the concrete mix, resulting in a consistent and uniform hue throughout the entire structure. This method provides a long-lasting and durable colour solution. Integral colouring is often preferred for projects such as driveways, interior flooring, and kitchen tabletops where a consistent and aesthetically pleasing surface is desired.

Topical Colouring

Topical colouring, on the other hand, involves applying colour to the concrete surface after it has been poured. This method offers more flexibility in terms of design and allows for artistic creativity since colours can be applied in various patterns and textures. Topical colouring is commonly used for projects such as patios, garden pathways, and outdoor steps.

Now, let’s take a look at the different types of colouring agents used in concrete:

Type of ColouringDescription
DyesDyes are easy to use and come in a wide range of colours. They are mixed with a solvent or water and provide the expected colour without surprises. Dyes are an excellent choice for achieving vibrant and intense colours.
PigmentsPigments are added to the concrete mix before pouring, and once added, they cannot be removed. They offer precise colour control and are available in a variety of shades. Pigments are ideal for achieving consistent and long-lasting colours.
StainsStains are used to change the tint or shade of concrete and can also alter the surface texture. Acid stains etch the top surface layer through a chemical reaction, while penetrating stains sink into the pores of the concrete. Film-forming stains work like paint, creating a colored coating on the surface.
Colour HardenersColour hardeners are used to strengthen and intensify the surface colour of decorative and stamped concrete. They enhance the durability and resistance of the coloured surface, making it ideal for high-traffic areas.

Each method of colouring concrete and type of colouring agent has its own benefits and considerations. It’s important to choose the right method and colouring agent based on the specific requirements and desired outcome of your project.

How to Pick the Right Concrete Colour

Choosing the right concrete colour for your project involves several important considerations. By taking into account factors such as the type of project, the condition of the concrete surface, the location, the desired aesthetic, and the budget, you can make an informed decision and select the perfect concrete colour.

Firstly, consider the type of project you are working on. Integral colouring, which involves adding colour directly to the mixed concrete, is ideal for projects such as driveways, interior flooring, and kitchen tabletops.

Your desired aesthetic and budget are also crucial factors. Integral colouring with pigments allows for precise colour control and may be a cost-effective option in the long run. Stains and dyes, on the other hand, tend to be pricier. Consider your budget and weigh it against your aesthetic preferences to make the right choice.

Gathering inspiration from design trends and consulting with concrete experts can also provide valuable insights and help you choose the perfect concrete colour. Their expertise and experience will guide you towards colours that complement your overall design vision while ensuring the best results for your specific project.

Concrete Colour Selection Tips:

  • Consider the type of project: integral colouring for consistency, topical colouring for flexibility.
  • Evaluate the condition of the concrete surface: fresh concrete is best suited for integral colouring, while older surfaces may require topical stains or dyes.
  • Take into account the location of the project: choose colours with UV stability components for outdoor surfaces.
  • Consider your desired aesthetic and budget: integral colouring allows for precise control, stains and dyes may be pricier.
  • Seek inspiration from design trends and consult with concrete experts to make an informed decision.

By following these tips and considering the unique requirements of your project, you can confidently pick the right concrete colour that will enhance the visual appeal and longevity of your concrete surfaces.

How Concrete Gets its Colour

Concrete gets its colour through the use of pigments, which are either mined from the ground or generated in chemical factories. These pigments come in three forms: granular, liquid, and powder. They contain iron oxide particles that are smaller than cement particles. When mixed with wet cement, the coloured particles surround and cover the larger cement particles, resulting in a coloured tint.

The ratio of pigment to cement determines the intensity of the colour, with more pigment required for darker shades. Grey concrete can also be coloured using water-based or acid-based chemical stains. The pigments used in coloured concrete are UV resistant and mixed throughout the entire concrete slab, ensuring the colour remains consistent and long-lasting.

This protective barrier makes cleaning and maintenance easier, promoting the longevity of the coloured concrete. Furthermore, sealing enhances the richness and depth of the concrete colour, giving it a polished and attractive appearance.

There are different types of sealers available for coloured concrete. Two common options are:

  1. Penetrating sealers: These sealers preserve the natural finish of the concrete while providing effective protection. They penetrate the surface and create a barrier against liquids, preventing stains and damage. Penetrating sealers are ideal for maintaining the original colour and texture of the concrete.
  2. Surface coating sealers: These sealers not only protect the concrete but also enhance the colour. They provide an extra layer of protection on the surface, adding depth and shine to the concrete. Surface coating sealers can give coloured concrete a glossy or satin finish, depending on the desired aesthetic.

To maintain the appearance and protection of coloured concrete, regular resealing is recommended. Typically, resealing every two years ensures continued durability and retains the vibrant colour of the concrete. This maintenance practice is essential for preventing deterioration and sustaining the overall quality of the coloured concrete surface.

Sealing coloured concrete not only safeguards its visual appeal but also contributes to its long-term performance and longevity. Adequate maintenance and protection ensure that the coloured concrete remains an attractive and durable asset for both residential and commercial projects.

Low Maintenance Solution with Coloured Concrete

Coloured concrete is a low-maintenance solution for driveways and other surfaces. With sealed coloured concrete, you can enjoy a beautiful and durable finish with minimal upkeep. The sealer provides 80% of the protection, making it easy to maintain the vibrant colour and overall integrity of the concrete.

To keep your coloured concrete looking its best, all you need to do is keep the surface clean and promptly clean up any spills. Regular sweeping or washing with water and a mild detergent is usually sufficient to remove dirt and debris. For tougher stains, you can use a pressure washer or a specialised concrete cleaner.
