Decorating living spaces or office spaces has proven to positively influence the well-being of those who occupy these spaces. Most prominent for painting are the walls and ceilings, the doors or the window-frames. But also furniture elements (indoors or outdoors) may need a fresh coat of paint. Besides a number of colours as supplied in the paint-container from which he can choose, the consumer can also individualize his colour choice at the mixing station in the paint-shop. The progress in ease of applying these deco paints has increased the use for Do-it-Yourself. Over 80% of the paints in this sector are nowadays waterborne and have therewith substantially reduced the emissions of solvents to air.
