The Art Of Replicating Nature

Contractors can now use coloured concrete to replicate nearly all of nature’s textures and colour tones which can result in an amazing concrete surface.

There are color approaches which are frequently chosen to combine with each other and also complement the natural surroundings. Often, coloured concrete is finished to appear similar to a gravel walkway or other natural elements like smooth stones and vegetation.

Frequently, it is essential to have the durability of concrete as well as its ability to last very long. Though in cases where the simple gray color of concrete will make it look like a drainage ditch or ordinary foot path, coloured concrete may be used to prevent this kind of attention on such attributes and aid those traits blend well with the other surrounding features. 

Using Colour Through Concrete to Cover Future Stains

The majority of driveways, parking facilities as well as other vehicle areas are finished with light gray colours which soon become stained by leaking fluids such as oil and grease as well as tire marks, and dirt from the tires.

Most owners of these surfaces should have a contractor add a dark integral colour through concrete to the surface and then expose the aggregate materials in the concrete with sandblasting methods which are medium to heavy and or by applying surface retardant substances. Even roll curbs may be treated in this same manner. The resulting colours of light salt and pepper grays of the aggregate mix well with the dark gray look of the cement paste underneath the surface of the colour through concrete.

Any motor grease and oil stains can be less obvious and may even become indistinguishable in the various shades of gray coloured thru concrete. Even the tire marks won’t be so obvious on an exposed aggregate coloured concrete surface.

Concrete Stains For Concrete Colours

The use of staining methods infuses a very deep colour tone which can’t be accomplished with other concrete colouring methods. Instead of creating a solid, opaque-like effect that looks like paint, stains penetrate the concrete to impart glowing, nearly transparent concrete colours which vary based on the concrete surface they are used on and the application methods utilized. The outcome can duplicate anything and everything; there is a polished marble look or also a tanned leather or natural stone and even stained timber floor appearance.

Many stains for coloured thru concrete are available in 2 general classifications: acid-based chemical stains and water-based acrylic stains. The majorty of acid stains is a blend of water, hydrochloric acid and acid-soluble metallic salts combined properly. These function by really getting into the surface and causing a chemical reaction to the hydrated lime also called calcium hydroxide within the concrete substrate.


Concrete Colours: The Tricky Method

Those acids within the stain softly etch the surface of the concrete, enabling the metallic salts to permeate even faster. As soon as the stain reacts, this becomes an everlasting component of the concrete and will never lose colour, chip away or peel off. The concrete colour choices for acid stains is usually limited to natural tones, like tan, brown, terra cotta as well as light blues and greens.

When you feel like you wish to move past those mild and restrained looks of the nature inspired tones and colours of acid staining, we can also think about water-based stains. These are available in a much wider palette of tones. The majority of product makers provide a multitude of standard colours, of course there is black and white for a checkerboard look and also metallic tones. Similar to acid stains, water-based stains, usually a mix of acrylic polymers and pigments permeate the concrete surface to create long lasting coloured through concrete which can range from nearly transparent to cloudy based on the kind of product used.
