Painting on wet or dry plaster as a revival of ancient art

painting on plaster - Secrets Excellence

Many puzzled shrug: "Why do I need to know any secrets out there painting on plaster, if it has professional artists?".That may be so, but just imagine that the master has covered the walls of your magnificent designs and drawings, received payment for the work, and took his leave, and you are left to enjoy the result of his work.But after a year, and the entire mural in your home cracks and crumbling in places and, with the master says that this kind of wall decoration is short-lived.And only then you will know that the walls had to be prepared in a special way even before plastering.It's a shame it would be, is not it?

This is why you should know that if you intend to decorate your house with frescoes, before applying the stucco wall surface should be a maximum distort all sorts of potholes and rather deep grooves.But this is only the beginning of preparation for decorative painting on plaster.Next, after pre-wetting , plaster is applied, which is a rough m

ortar, one component of which should be coarse sand or crushed into crumbs shards.Also in the mix is ​​placed in a small crumb of broken brick and very finely chopped straw.All this is placed on the wall by a layer of 2 cm or more (the maximum allowable thickness for leveling walls curvature - 5 centimeters) without grout to keep the surface rough and uneven.The maximum that is allowed - it is to ride on a layer of plaster or bottle to break a piece of wood for a seal and a better coupling with the wall, and then apply the diametrical scratch for better lapping the next layer (the wall should happen "in a forward cell").

So, the first layer of plaster is applied."As only the first, not too much plaster?" - Ask someone.Even small, since all can be up to seven layers of plaster, each of the following is not applied before the previous is completely dry.New layers become thinner and grain components, respectively, decreases.The last layer, up to 3 mm thick, contains the smallest quartz sand, and certainly it can not find the fragments of brick and straw.And the last layer is applied to small areas, such exactly what area can reach the master at the time of painting on wet plaster until it is completely dry, ie a maximum of 5, and ideally 3 hours .After this time the surface of the plaster grabs calcium crystalline crust and the paint will not stop what is absorbed, but also applied.

painting on plaster as it is

Earlier artists have acted in a hurry due to the extremely fast drying plaster (on average, the painter was 10 minutes to cover the pattern prepared area), then today in painting on wet plaster permissible slowness and thoughtfulness.In particular, there is no need to cover the wall pattern "by eye", because you can easily prepare a drawing on paper and move it to the wall surface.How?Just cutting the image into separate pieces of equal size sections are prepared for a session of painting and shifting contours of the image on fresh plaster using a needle or sharp pencil by extrusion.Sometimes used way to transfer the pattern on the wall with priporashivaniya art (piercing needle holes in the drawing, and thus leaving marks on the plaster).To the basis for drawing it was perfectly white, can be applied to the finishing primer for painting on plaster diluted mortar.

When drawing circuit applied to the finishing section, the artist begins to work with soft brushes, easily pushing the pile, not to lubricate the layer of plaster in a couple of millimeters thick.If swabs are applied carelessly, there is a possibility that part of the lime will be raised with the finishing layer and mixed with paint, which after drying would be whitish.Invalid and a thick layer of paint, as it will not be absorbed into the plaster and subsequently, after drying, cracked and osypletsya.Therefore, please remember all the details and carefully monitor the process of the artist, standing next to a very profound views - though not relaxed.

painting on wet plaster and its alternative

painting on wet plaster technique is very peculiar.Initially, only the light inks are superimposed, where they provide a pattern, and then the midtones, and dark ink end.Then the master begins to work in reverse, first prokrashivaya dark colors, then the middle and at the end of light.Why so complicated?Just as you go from light to dark, while the artist gives bright colors soak into plaster, and then, in the reverse movement from dark to light looks, where bright colors were too faded, and tints the desired areas.In addition, the second phase of work allows to impose on the dried light areas where it is needed, darker tone. There is evidence that once the artists involved in painting the walls, to increase the clarity of colors under the blue paint was applied on the ground ocher gray (Reft), and under all the rest - yellow.Sometimes when to some portions perform paler color, for example, to transfer the picture or prospects for image fog in white lime paint is added.However, small amounts of lime in the paint for murals found always to be well fixed.

When the wizard finishes painting decorative plaster, already pretty dried up, the blank areas of soil finishing neatly cut off from the previous layer obliquely outward.The next stage of painting a new section of the finishing layer is applied as close to the seams to be seen.Painting on plaster requires care, since it is impossible to alter the fresco section, you can either make a slight correction, or start all over again.

completely different technique - painting on dry plaster, it is rarely used technique of the old masters, "a secco" that, in fact, means "dry".Pretty good alternative, since the finishing layer can be applied directly on the wall and just moisturize it to those areas where the painting to be done.Only here the solution should be special - lime putty with ten percent aqueous solution of casein glue.A fluid composition similar to milk (not recommended to drink) three times is applied to the plaster, and the next layer is applied begin no earlier than the previous did not dry up.Paints for painting on dry plaster can be used any - oil, adhesive, but is best used tempera.

great masters of the past have used tempera own cooking, and many secrets now lost.And if you need them - in fact already there are so many options for painting on plaster.Choose any, and let your home become a true work of art.
