Rules for applying facade plaster. Facade finishing: decorative plastering. Home design with silicone plaster

All of these additives contributed to the strength and durability of the plaster. The appearance of a lot of plaster was determined by the color of the sand - or sometimes burnt clay - used in the mix, but often the plaster was also tinted with natural pigments, or the surface was whitewashed or painted after finishing the plaster. Brick dust can provide color, and other dyes not affected by lime, mainly mineral pigments, can be added to the final coating mix. The plaster was also marble or marble - painted to look like stone - diluting the dome oil with water and mixing it with yellow ocher or another color.

As the twentieth century progressed, the factory added manufactured or synthetic pigments for some prepared plaster mixes. Many formulations included the use of hair, jute, flax, or straw as fillers. Animal hair gives lime and sand great strength and adhesion; it has long been used as a binder in lime and gypsum plasters.

Ear hair was commonly used, but horse, goat, and even human hair were used as substitutes. However, the use of human hair was rare due to its thinness and weak strength. Examples of external plaster. ... Historical external renderings include a wide variety of aggregates, binders, and reinforcements. Simple classifications include types ranging from very low strength strokes, usually applied in a single thick layer to support a weave or plank, to high strength renderings based on hydraulic cements applied in two or more layers to brick or stone or lime undercoats.

Other types include low to medium strength deposits based on lime applied in two or more layers to support brick, stone, unfired earth, netting or plank; and medium-strength oil mastics, commonly used in a single thin coating of brick, stone or lime, but also used to model parts. Historic exterior plastering includes parrying, sgraffito and marmorino. Treatments and coatings associated with plastering consist of at least a portion of a plastic or malleable material, including weaving and brushstroke and cob.

These are regional differences in traditional mixtures of mud, clay, lime, chalk, cement, gravel, or straw. A railing is an exterior decorative plaster that is often cut or modeled with decorative prints or designs made with mold or comb. It consists of a tough lime plaster made from lime putty or mixtures of lime and gypsum plaster reinforced with wolf hair, and with a tall oil additive sometimes added as a plasticizer and water repellent.

The surface of the cobweb was poured frequently; sometimes used as a protective coating linseed oil or wax. During the Renaissance, ash-stained lime plaster was used as the bottom layer and then covered with white lime plaster. The lowest leveling layer then usually consisted of Portland cement, over which a layer of cement dyed with earthy pigments was applied. The last layer for interior work was parium cement; Portland cement was used outside. With all materials, the layers were allowed to dry, but not fully set until the design was cut with an iron stylus or knife used to remove the top layer.

After the plaster or cement has been fully installed, areas of the structure can be oil-gilded. In more open areas, additives such as metallic sand were added. Low-strength wattle and daub consists of intertwining sticks, twigs or branches plastered with clay, grease or dirt. For roofs, walls and fences, especially in the early 19th century, weaving and brushstroke designs were used. Traditional mixes also include mixes of lime putty, sand and slurry cow dung, fortified with chopped straw.

Sequence of works for plastering the facade

Cob - walls made of clay, earth, straw, lime and sand mixed with water. Wet clay or chalk will scare off a horse with a straw or reed. It is built without blinds in layers on a stone or brick plinth. It is pressed against the walls, the surface is cut off as it hardens. It is usually covered with protective linen or plaster. However, it should shed light on the variety of materials and mixtures used over the centuries, and especially in the last two centuries. Their use sometimes gave rise to persistence problems, and now we are faced with the problem of preserving them.

It is only by knowing for sure that the composition of these materials makes it possible to ensure the survival of the remaining examples. Biscont G. Piana M. and Riva G.

Advantages of decorative facade plaster

The product eliminates the phases of plastering, plastering and plastering, one application with a dedicated projection machine, which ensures a good finish and a high speed of coatings. The speed of application depends on the projection directly onto the walls, providing time savings with the same amount of labor. The product makes surfaces more perfect, compact and smooth, which makes painting maintenance easier.

For places where there is no need for final finishing very High Quality, to ensure a satisfactory result, it is sufficient to carry out waterproofing between the designed plaster and the wall paint. How should the procedure be in each case?

Felipe. Project plaster requires the use of a specific projection machine. However, projection is only the first step, followed by manual surface regulation processes, coating uniformity and final smoothing. Projection reduces application time and labor cost. For example, a team of four can complete up to 200 m² of surface area per day. However, the speed of execution is higher if the masonry is of good quality and flatness, as well as good planning and general organization of work.

Felipe - Thickness may vary on one surface. Depending on the flatness of the masonry, we can find large differences between the thickness of the plaster in different areas of the surface to be coated. It is clear that the more irregular the surface, the greater the need for its regularization, which requires more time and more product.

What is the formulation of gypsum mortar? Adhesion is carried out directly on the surface without the need for any other treatment. Projected gypsum consists mainly of limestone, gypsum powder and additives that determine, for example, product run time and the level of adhesion to substrates. The product is designated for covering interior walls of masonry, ceramic block or concrete, other than covering slabs and pillars, with a specific projection machine.

Plaster the wall with a "bark beetle"

This eliminates the sanding, plastering and plastering phases. What is the cost of the application per m²? Where should this solution not be applied? The speed of application depends on the projection of the plaster by a particular machine directly onto the walls, which saves time with the same workload. That is, using a projection machine, the installer makes more m² per day, in direct comparison with a manual process by 100%. Already prices vary depending on the region of the country and the quality of the surface that needs to be covered in the work.
