Concrete walls must always be prepared before painting, but in some cases previous finishes will also have to be removed so that paint doesn't peel or chip off. Additionally, special sealants, primers and paints may be applied to ensure concrete's endurance in face of the specific elements. Depending on the wall's condition and exposure to the sun, painting professionals will usually estimate between $500 (~250 sq. ft.) and $2,000 (~1,000 sq. ft.), depending on wall area to cover.
The psychological effect of green is largely dependent on the tone or hue. Some green hues create a positive, natural atmosphere. However, darker hues or pale olive green can seem militaristic or ill. Multiple shades of green can serve different purposes and set different moods. Maritime greens are ideal for studios and offices as they inspire concentration, while cool forest greens can be used in bedrooms and bathrooms.
