In the construction of private or city houses, as well as various kinds of structures, materials that are not very resistant to moisture are often used. It can be concrete, wood, brick, etc. Such surfaces must be waterproofed during the construction process. In most cases, roll materials are used to protect various kinds of structures of buildings and structures. But sometimes dry waterproofing mixtures are also used for this purpose. There are several varieties of such compositions.
What are the types according to the manufacturing method
In this plan, all dry waterproofing mixes are classified into:
- cement with polymer additives;
- elastic with plasticizers.
Both of these varieties can be used for moisture protection of floors, walls, foundations, etc.
Cement mixes: characteristics
Such compositions are used by builders in the construction of buildings and structures very often. They are made, as can be judged by their name, using cement. Ready mixes of this type in appearance resemble ordinary plaster. They are applied to the surface, if necessary, using approximately the same technology as finishing materials. Actually, special components, polymers, are responsible for waterproofing in such compositions.
The thickness of the moisture-proof layer made using mixtures of this type is usually 4-5 cm. Subject to all the required technologies, waterproofing of this kind can easily withstand water pressure of 5-6 atmospheres.
Reviews on cement mixtures
The advantages of waterproofing compositions of this type builders include, of course, ease of application in the first place. Also, the advantages of cement waterproofing are:
- low cost;
- possibility of application on surfaces of almost any material;
- environmentally friendly.
The disadvantages of waterproofing dry mortars of this type builders include:
- Crack instability;
- need for layer reinforcement;
- duration of the application process.
When using waterproofers of this variety, experienced craftsmen advise beginners inAccurately comply with all required technologies. Otherwise, water-repellent layers of this type will not last too long.
What are elastic blends
Such compounds, in turn, can be:
- elastic;
- semi-elastic;
- hard.
From purely cement mixtures, such mixtures differ primarily in that they are applied to the surface with a thin layer. In addition to polymers, the composition of such mixtures includes various kinds of plasticizers. This type of waterproofing can be applied to structures built from materials of any density.
Elastic compound reviews
The advantages of the compositions of this type of builders include, first of all, the speed of application. The structures are coated with waterproofing agents of this variety, usually in only one layer. The advantage of such mixtures is also considered their low cost.
The disadvantages of elastic compositions builders refer primarily to fragility. Also, the disadvantage of this type of products is the need for complex preparation of surfaces for their application.
Varieties by purpose
Dry waterproofing mixtures, among other things, can be classified according to the method of application. In this regard, there are compositions for:
- penetrating insulation;
- coating;
- stucco;
- bookmark.
All these types of waterproofingconstruction are used very widely.
Penetrating formulations
Mixes of this variety are usually made with the addition of cement. They are mainly used for waterproofing porous concrete. After application to the material, they penetrate into its thickness and form crystalline bonds. That is, in fact, dry penetrating waterproofing mixtures become part of the structure itself, significantly increasing its hydrophobicity.
Reviews of penetrating waterproofers
The advantages of such mixtures builders refer primarily to the effectiveness of hydroprotection. Also, the advantage of deep penetration means is a long service life. Reliably protect the treated structure from moisture, such a composition will be throughout the entire period of its operation.
The disadvantage of such waterproofers, judging by the reviews of the masters, can be considered, first of all, that they are quite expensive. Also, some of the disadvantages of this type of funds include the difficulty in applying. Working with such compositions requires certain skills. This applies, for example, to dry waterproofing capillary penetrating mixtures.
Coating agents
Such waterproofing compounds are the most popular among builders. To protect against moisture on various kinds of structures, they are simply applied with a brush. It is to this group that dry elastic mixes belong by purpose.
Besides waterproofing,coating compositions perform on various kinds of surfaces and another important function. Such materials protect building structures well from the appearance of fungus.
Plaster compositions
Such dry waterproofing mixtures usually belong to the cement group. Compositions of this type are used most often to protect against moisture foundations, basements, underground parking lots, etc. The features of this type of waterproofing, among other things, include the fact that they can be used in combination with any others, for example, penetrating.
What are stowing mixes
Compositions of this variety, in addition to the main components, contain additives that actively swell when wet. Waterproofing agents of this group are used mainly for sealing foundations, basements and walls. They are laid in cracks, spaces between plates, crevices, etc.
Reviews about backfill mixtures
The advantages of such compounds builders include primarily low cost, low consumption and ease of use. In addition to repairing cracks and holes, experienced builders advise using the products of this group for processing very uneven surfaces. According to the masters, such structures can be reliably protected from moisture using only filling compositions.
Popular brands
On the domestic market today you can buy waterproofing of this variety from both domestic and foreign manufacturers. For the most part, compositions of this type are distinguished by goodquality. But some brands of materials of this type have earned the best reviews from builders.
Very good masters speak, for example, about dry waterproofing mixtures "Penetron". These plaster cement compounds are usually used only for waterproofing concrete surfaces or old plaster.
From imported waterproofing agents, LITOKOL mixtures are very popular among domestic consumers. This manufacturer supplies the market with both cement waterproofing and elastic.
