Concrete floor technology continues to evolve to meet the needs of building owners at a rapid pace. The CFCAO is pleased to offer coloured concrete surfaces that create ambient improvements which are extremely durable, compatible with other finishes (eg: polished concrete) and are practically maintenance free.
There are two types of pigment colouring for concrete: 1) Surface Colouring (colour added to the surface of the concrete) and 2) Integral Colouring (colour mixed into the concrete). Each of these options has strengths and weaknesses that must be considered carefully.
Surface colouring is the method most used for interior surfaces. The material composition includes both a pigment and a hard-wearing aggregate. The result is a surface which is both coloured and much harder wearing than integral coloured or plain concrete.
Integral colouring is most often used in exterior applications. The use of integral colours does not affect the freeze thaw durability of concrete. Integral colouring is also ideal when combined with deep grinding polished concrete applications, where the surface is removed. Integral colouring does not increase wear resistance and surface density like surface colouring.
Surface Pigment Colour Benefits
- Creates improved abrasion resistance and surface hardness
- Reduced surface porosity
- Colouring at the surface only
- More economical than integral colour
- Can create energy savings with light reflectivity
Integral Pigment Colour Benefits
- Ideal for exterior Applications with air entrained concrete
- Ideal for deep grind exposed aggregate polished concrete applications
- Coloured throughout the concrete
