Grounding, Material, Technique
Painting directly onto the inner wall or facade
Mural paintings done on inside walls on location are usually painted onto correctly prepared walls with acrylic colours, and, if necessary sealed off with a special varnish with a matt finish. This improves the durability and allows the work to be cleaned off with a wet cloth.
The wall that is to be pained must have certain qualities: it must be able to “carry” the painting, it should be smooth and polished as well as carefully pretreated with a primer, where necessary. A high quality, matt, white dispersion wall paint will, depending on the size of the area that is to be painted, be either applied by us or a painter beforehand. Ideal preparation for paintwork on plasterboard is a reinforcement and full scale level in with quality grade Q4.
Depending on the required delicacy of the painting, the surface does not always have to be perfectly smooth. Especially on outside areas and walls we sometimes work on roughly plastered, slightly grainy surfaces, which are primed with facade colour. It is not necessary to smooth the facade, if the size of the painting and the eventual distance it is going to be viewed from (such as high up) does not require any minute details. Very grainy surfaces however don’t suit our way of doing work and are ill fitted to our style.
On facades, depending on the surface, we use dispersion silicate colours instead of acrylic colours, or other products which are specifically designed for a layer building painting. Mural paintings painted with dispersion colour should be stabilised with UV Varnish.
Painting on a movable base (canvas, panel, paint substrate)
Alternatively, instead of directly painting onto the wall, one may use a canvas, paint substrate or other movable bases, which can then be installed (and later, if required, removed) on site. We wallpaper our robust canvases with glass fabric adhesive or dispersion adhesive onto the surface. This job can also be done by any qualified decorator.
Our canvases are up to 2,1 metres wide and 10m long. Paintings that go beyond this format will be composed of several canvases and this will be done in such a way, that the cutoff points between the several canvases will become unrecognisable through the use of painted floor joints, horizontal lines or architectonic borders.
Pictures on MDF panels may also be mounted on walls, where the surface is ill suited for a painting. In most cases the panels are easily removable without leaving any noticeable damage and can then be installed in a different place.
Real fresco and silicate glazing
The impression of real chalk frescos can be done to a very satisfactory level with a fraction of the technical effort by using one component silicate glazing. Compared to painting with dispersion colours, the plasticised silicate glazings have the advantage of having increased water vapour permeability, making this material a lot more suitable for listed buildings or facades with a mineral composition.
