| | | Various types of plaster are available on the market, some are synthetic, others are natural. Bio-architecture recommends the use of natural plaster only, that is less harmful for our health. It is made of lime and sand mortars and doesn't contain cement. Lime mortar is resistant to humidi- | | ty and mould, anti-bacterial, extremely transpiring and an excellent heat insulator. Slow hardening due to the presence of dicalcium silicate gives this plaster excellent resistance to sudden changes in temperature, perfect adhesion to the base to which it is applied and excellent ela- | | sticity. These features result in extreme durability and very high reliability, guaranteeing great resistance to flexion and compression. For as much as regards paints, silicate paints made of potassium silicate and natural mineral pigments are excellent. They are transpiring, hygienic and have a high | | tolerance to humidity because they are very permeable to water vapour. The choice of colours is also important in a kitchen because it affects the luminosity of the room: light colours make spaces look larger while warmer colours create the right harmony. | | |
