Stucco is what? Putty and plaster - what's the difference?

Plaster is a composition that allows to form a finishing layer. There is a word from the Italian stuccatura, which means lime, gypsum, alabaster. Classify the plaster can be used. It happens:

• Conventional;
• Special;
• Decorative.

Description of the main varieties of plaster

Conventional plasters are used for leveling walls, forming an even flat surface for subsequent application of thin-layer decorative coatings. These compounds can protect the facade from the effects of the environment.

Special plaster is a mixture that is used in the role of a shielding insulation layer. This material allows to provide sound-absorbing, X-ray protective and heat-saving properties. As for decorative plaster, it is used for finishing the ceilings, walls, as well as structures, which allows to increase their aesthetic expressiveness.

Varieties and description of decorative plaster

Decorative plaster is a composition that can be classified according to several varieties. Among them:

• Color;
• Stone;
• The Venetian;
• Terrazitic;
• Silk.

Color varieties are suitable for finishing window and door openings, as well as interior walls. Stone plaster appearance resembles a natural stone. The Venetian variety is like real marble. Terrazitic mixture is used for finishing facades and internal walls.

Features of silk plaster

Silk plaster is designed for interior work. It is not combustible, it consists of synthetic or natural fibers, does not accumulate static electricity, but can have different textural and color solutions. When applied to the surface of silk plaster does not form seams, the material does not crack when shrinkage, it differs elasticity.

Silk plaster is a composition that has only one drawback, expressed in low water resistance. However, if the surface after drying is treated with waterproof varnish, the composition can be operated in rooms with high humidity. These include bathrooms and kitchens.

The most popular traditional plasters

The most common conventional plasters today are:

• Lime mixture;
• Cement-sand mortar;
• Gypsum material.

Lime solutions are used for external and internal works. The main advantage of this material is speed and usability, as well as high environmental friendliness. There are limescale solutions and disadvantages, which are low strength compared to other materials.

These solutions are made from river sand and hydrated lime in a 4: 1 ratio. Cement-sand plasters are used for exterior and interior works. The prevalence of these mixtures is due to the cheapness of the material. It is characterized by a higher application complexity, but the coating is more durable than gypsum or calcareous solutions.

A solution of sand and cement is prepared in a 4: 1 ratio. Lime or PVA glue is added to increase plasticity. If the technology of application is observed, the lifetime of the coating will exceed several decades. Cement-sand mixtures allow the surface to be freed from deep flaws.

Description of gypsum plaster

Interior plastering is usually carried out using gypsum composition. With its help you can achieve a smooth white coating. As the main disadvantage of this material is a higher cost in comparison with analogues. One can not help but note the weak vapor permeability, low strength and insufficient moisture resistance.

Producers quite often try to save by adding to the gypsum plaster unfavorable to human health chemical substances like asbestos. They give the surface a whiteness. But gypsum plasters allow to simplify the cycle of finishing and to reduce the time spent on the alignment process.

The difference between plaster and putty

Quite often, consumers are asked about the difference between plaster and putty. These are completely two different materials. In order to understand the difference, it is necessary to understand what these mixtures are and what they are intended for. For example, plaster is a building compound with which you can smooth out the inner and outer walls, as well as ceilings. Putty is a building compound for smoothing the surface of walls.

Between these two materials there is a difference, it lies in the fact that the plaster allows you to level uneven walls and blockages, while putty can cover up minor defects, seams and cracks. Therefore, this solution is often used for finishing gipsokartonnyh sheets. The puttying differs from the plaster also in that it practically does not shrink.

If you use plaster at home, it will also save you money, because it is cheaper at the expense of large-fraction mineral filler. This mixture is much stronger than putty, because for strength when concreting, crushed stone is added to the ingredients. This is the right solution for plaster, because strength depends on the filler fraction. This also explains the fact that this mixture is superimposed on a rather thick layer.

If you still can not decide whether to putty or plaster, then you need to deal with this issue in more detail. Plaster, for example, allows you to equalize the debris, ceilings and walls. If, however, there is a need for alignment of defects, scratches, cracks and potholes, as well as chipping, it is necessary to use the filler. When it is necessary to apply a layer more than one, then plaster is used, otherwise it is necessary to obtain the putty. Now it is clear that for the initial wall finishing, plaster is required, and only after that it is possible to start applying a putty that perfectly prepares the surface for gluing wallpapers or painting.

Positive feedback on the plaster "Bark beetle"

Plaster, the reviews you can read below, can be used by you for different jobs. For example, the species "Bark beetle", according to consumers, has many advantages. The material is strong, environmentally safe and reliable, because it is made from natural ingredients.

The composition is extremely light, since it has mineral fillers, which eliminates the load on the structure of the building. Consumers like that the material is resistant to weather changes. It carries direct sunlight and low temperatures. Do not be afraid of the "Bark beetle" even hail or hoarfrost. Decorative plaster can be applied independently without any problems. After drying, it acquires refractory properties, and the original brightness is not lost even under the influence of ultraviolet.

Caring for the coating, according to customers, is quite simple. It can be washed with water, in which a small amount of detergent is previously added. Quite an important factor is also the fact that the layer does not create favorable conditions for the emergence and development of fungus and mold.

Home masters choose "Bark beetle" also for the reason that it is quite difficult to damage, so you can clean the surface with a vacuum cleaner or a hard sponge. Visiting the store, you can pick the right shade of "Bark beetle" from a huge range of colors. Usually this decorative composition has a white color, but afterwards the surface can be painted in any shade. Plastering of walls with "Bark beetle" allows to save also, therefore the given mix is so popular.

Features of machine wall plastering

Machine plastering of the walls allowed to ensure the speed of work and saving the solution. The mixture is consumed in smaller quantities because it is saturated with air, and as a result, its volume increases. As practice shows, the application of three layers on the surface with the help of the machine method allows you to save up to 9 kg of composition per square meter. Plus, the machine way is that manual mixing is replaced by a mechanical one. The mixture is uniform, due to this on the wall does not form irregularities. It is quite easy to operate the machine, and the result will be a high-quality and even wall decoration.

Application of plaster with own hands

If plaster was chosen as the material for the finishing, the work can be done independently. To do this, the surface is cleaned and primed, and after drying, you can begin to finish. The dry mix is diluted, but it is not necessary to mix all the available packaging at a time. The mortar should be spread evenly with a spatula.

The layer should not be thicker than the size of the granules. Textured plaster is applied in horizontal or vertical rows. In one pass it is necessary to capture the entire height or width of the base. Once the plaster has been applied, it should be left for 20 minutes for easy setting, only after that it is necessary to start the troweling, which should be done taking into account the desired pattern. Staining of texture plaster is carried out on a dry layer with the help of a brush or roller. The dye can also be added to the solution, and on the surface the mixture is applied in a colored form.

Conclusion

Before applying the plaster surface can be supplemented with beacons that will allow an inexperienced master to perform a quality alignment. If we are talking about internal works, then the application of the composition is carried out in several layers. Fine-grained plaster is usually used for interior finishing. If among the ingredients contains a medium-fractional filler, the solution is better used for finishing the facade. Most often, plastering "Bark beetle" is realized in the form ready for application.
