Stained concrete is used for exterior and interior design. It offers an almost unlimited color palette: white, black, blue, red, brown.
CHOOSING STAINED CONCRETE
One can ask the question: "why tint his concrete"? The answer is simply "and why not? ". Concrete in its simplest form is not so aesthetic. If decorating a little more expensive than leaving it as it is, the rendering is much more satisfactory! Stained concrete offers a range of choices and unlimited colors: blue, yellow, green, red, brown etc ... which gives unique results. The Stained concrete comes in many colors and variations this color: blue, white, black, yellow, brown, gray. It is an ideal material for outdoor landscaping: slab, garden path, terrace.
STAINED CONCRETE: A LIGHT MATERIAL FOR OUTDOOR DEVELOPMENT

You can combine color with surface treatment: deactivated concrete, printed concrete, bush-hammered concrete.
Two techniques to make a Stained concrete
To make a stained concrete, two techniques are used:
the hue in the mass
and the hue on the surface.
CONCRETE STAINED IN MASS
Concrete stained in the mass consists of incorporating the coloring elements directly in the mixture, into the mass of the materials. The color of concrete is played on three components: color pigment, cement and aggregates.
THE 3 COMPONENTS OF DYE
- Dye 1: color pigments
Color pigments change the color of the concrete. They are very fine. They can be natural or synthetic. Concrete pigments are generally dosed at 1% to 3% of the weight of the cement. This means that the amount of pigments represents between 1% and 3% of the amount of cement incorporated.
- Dye 2: the cement
The cement also plays on the hue according to its own hue. It can indeed be gray or white.
- Gray cement provides a basic shade on which color should complement each other. It is often added dark colors.
- The white cement allows a tint of lighter colors that would be difficult to impose with gray cement. The color is therefore purer but the cement also costs more.
- Dye 3: sand and pebbles
Aggregates also play an important role in the color of a concrete. Indeed, the hue of a "raw" concrete depends mainly on the smallest elements: pigments, cement, sand. In addition, a surface-treated concrete such as deactivated concrete, that is to say with apparent aggregates, will have a color dependent on pebbles and sand. Thus, the dyeing of concrete is the result of subtle mixtures between pigments, cement and aggregates. So you have to think about the final color before you start building, because lighter colors require a white cement rather than the traditional gray.
This dyeing technique involves sprinkling the fresh concrete with a colored hardener. Two products can be used: pigments or colored resin.
- The pigments have a rendering of beautiful finishes, 20 days after application.
- The colored resin is more resistant but takes about ten days to dry and is applied in three layers.
