Distemper (paint)
Distempers are coatings that use glue as a binder and water as solvent. As a white pigment and filler limestone powder, lithopone or chalk are used more colored pigments may be added. It is therefore sometimes referred to as leimvergütete lime paint, which is true only partially. In German-speaking Switzerland it is called " blanc fixe ".
Properties, uses
Distemper can be supplied as a powder and must be mixed before use with water only. There are also being made materials.
Because the glue is water soluble even after drying, the coating is sensitive to moisture. For outdoor use, so unsuitable, distemper, however, is recommended in rooms such as the kitchen, bathroom or basement very since saturate the chalk and glue with water vapor and leave these in due course. The result is a balanced air moisture, mold and the like find no breeding ground. Through their reversibility distemper can only again be painted with distemper, but not by other types of paint (eg dispersion and silicate paint ); also on the paper is rather risky. So distemper must be washed with warm water from the wall in the context of such a renovation before the new, modern wall painting.
Distempers also be used in artistic painting.
Pros and Cons
In the building and home improvement area distempers are considered obsolete and have been long since emulsion paints, silicone resin paints (also called " living room colors ") or ( organo) silicate paints ( mineral paints, water colors of glass ) displaces. In recent times, but painters pay attention to their excellent Renovierbarkeit and special qualities again and again: Leimfarbanstriche can almost indefinitely again be painted with distemper, without affecting the wall is shut off or indoor environment suffers. For the authentic restoration of a LUNA of the 19th century ( Biedermeier, founder time) distemper is the first choice, with its own aesthetic appeal: The color has a very good coverage and luminosity, and yet at the same time - through the integration of the color pigments into the glue - a very subtle, tempered and tempered character.
Distempers are produced without synthetic resins and may therefore be considered as particularly environmentally and health friendly, moreover, they are usually quite inexpensive.
In gritty, salable materials may contain smaller amounts of synthetic resins, polymer resins usually ( dispersion binder ) for ease of application. This effect on the reversibility. The result is a more cumbersome removal of the distemper to be renovated.
