With any repair without stucco, do not do. With it, various surfaces are processed. There are plaster or cement plaster. What formulations are better to apply – depends on several factors that will consider below.
This type of coating varies in its intended purpose. Conventional plaster use for construction work. With it, you can align the surface, close the seams, reduce the loss of heat. It can perform noise insulating function or serve fire protection.
Decorative plaster is a mixture of different colors and used to finish the room, and such plaster recently becomes popular. With it, you can realize very interesting ideas in the design of rooms of various purposes.
Plaster is divided into species, depending on which component in it is the main – cement or lime, clay or gypsum. There are other options with the addition of certain substances. But many are inclined to believe that the best plaster or cement plaster.
Before choosing one or another type of plaster, you need to make a comparison, and decide what characteristics at the moment when carrying out repair work will be preferable.
Such plaster is usually prepared from powder, diluting with water in the required proportions that are indicated on the package. As a result, it must be a paste, which is most often applied by one layer.
Such a solution is used to align the walls, preparation for painting or sticking wallpaper. This is exactly the plaster from putty, which, in turn, is used when there are more significant defects in the form of cracks and holes on the surface.
Gypsum plaster has several advantages:
- It is essential that it refers to environmentally friendly materials.
- With its help the wall can be made perfectly smooth.
- This type of coating does not give a shrinkage, and after its complete drying, the appearance of cracks on the surface is excluded.
- Its weight is quite lightweight, so there is no load on the walls.
- The elastic structure allows you to apply dense layers of the composition on the walls if there is a need. But even then you can be calm and not worry that a crack can appear somewhere.
The difference between the cement gypsum in the fact that the reinforcing grid is not required during work, while it is simply necessary when cement-sand plaster is used. Thanks to the porosity of gypsum plaster, the walls do not suffer from humidity. And this is a very big plus. After all, with fungus and mold, I don’t want to fight anyone. Due to the low thermal conductivity of the gypsum, the walls retain heat. And in terms of noise insulation, the indicators of this material are quite high.
The speed of repair using plaster plaster depends on which layer will be applied to the wall. If it is very fat, it is better to wait a week for reliability. With a thin coverage of enough two days.
There are some shortcomings of gypsum plaster, although their very little. Minus that is not so significant for many – this is the price difference compared to other types, for example, with cement plaster, which can be one and a half, and even twice cheaper.
And one moment. Gypsum plaster can not be applied in those rooms where humidity is constantly improved.
This stucco can always be made with your own hands fast enough. Need to have water under hand, cement, lime. Sometimes when it is prepared, the sand is still used.
This stucco has a fairly wide range of possibilities. It is indispensable when processing walls in a bathroom or pool, kitchen or basement. It is good to separate with its help the outer walls and the base where increased frost is required.
If we talk about the merits of this type of solution, it is durable and reliable, You can not doubt it. Many consider these indicators particularly important when they stop their choice on cement. This composition is well falling on any surface. His density does not allow to penetrate moisture inside and damage the design. The price of cement plaster is low, which allows you to purchase it at any time.
Cons also have them necessary to take into account. You must not forget about the thickness of the applied layer, here you need to remember that the weight of cement plaster is quite large. When plastering the ceiling, this composition is rarely used. Incomcribe this kind of mixture with wooden, plastic and painted surfaces.
When it is applied, it is necessary to align and putting. Dries this composition long. It can completely open it in three, but in some cases and four weeks later. But when choosing a cement plaster in building stores, you need to pay attention to the fact that now many manufacturers were able to improve this composition. By adding certain components, the cement can be done more elastic and reduce surface drying time.
How to apply?
When studying the positive and negative characteristics of the compositions, it is necessary to pay attention to which of them will be more convenient in each specific case, and whether additional materials will be required during repair work.
Gypsum plaster practically does not have drawbacks. But with insufficient speed of work, a cooked solution can dry, you have to do a new. And the price of this material is not low. Consequently, in the absence of experience, it is best to make a solution with small parties. Maybe it will not save time, but you can be sure that all the plaster will go into business, and not in waste.
When cementing the surface requires installation of reinforcement. Save a solution for a long time. Therefore, you can safely breed a large volume and cover immediately significant areas.
There is another important advice. Works need to be produced at a plus temperature ranging from five degrees. Be sure to pre-use primer with deep penetration. Before applying the next layer, you must completely give to dry the previous.
Each method and solution has its advantages. This is also told reviews. Those who proceed to repair are already familiar with the characteristics of materials that plan to use. Therefore, there are no surprises.
Some notes that outdoor work is easily and quickly passing precisely thanks to the cement solution. Duration of drying up pays for such a treatment for a long time. Others share the experience of applying plaster plaster in the rooms, and at the same time it is praising for the fact that after its application with the walls you can produce any manipulation, provided that the entire technological process is observed.
Paint falls perfect. Wallpapers do not bubble and not fall off. And this is a very important factor.
Subtleties of preparation of mixtures
The initial stage in any repair work is considered to prepare the necessary compositions and tools. The first step is mixing dry components, the second – the addition of water.
The preparation of each plaster has its own nuances:
- Powdered components of cement plaster (cement and sand) are connected primarily. Only after careful mixing in them you can add water. Then all this is well mixed to homogeneous mass. Will not be much difficult to prepare the plaster in which plaster and cement will be present. Such a solution will dry faster, but will become less durable.
- Cooking gypsum plaster occupies literally five minutes. First, the plaster is brought to the test consistency, and then water is added if necessary, so that it is precisely the composition that needs.
When applied to that and other plaster need certain tools that need to be stocking in advance. It is possible that in the process of work it turns out that somewhere on the surface the old coating remained.
Therefore, the following tools will be needed:
- Metal brushes;
- a hammer;
- mixture capacity;
- electric drill or mixer;
From all the above, we can conclude that each plaster is indispensable when repairing, it all depends on which surfaces to it to process. Under compliance with all technologies, it is possible to perfectly treat outdoor walls, cement places with cement plaster, and in the rooms used plaster.
