"M-150" (dry mix): characteristics, features, application

Today in the construction market there are many drymixtures designed to greatly facilitate and speed up the workflow. The basis for their production is cement and sand, to which, in order to improve the technological properties of the finished solutions, plasticizers are added to the production. The consumer has only to open the package, pour out the necessary amount of material, add water and mix until a homogeneous mass is obtained.

One of such materials is "M-150". Dry mixture of this brand is produced for different types of work - installation, laying, finishing.

Features

Thanks to the use of special technologies onproduction and optimal ratio of components, the material acquires unique qualities, extremely important and necessary for repair work or for construction. It:

1. Reliability.
2. High quality.
3. Excellent degree of adhesion with bases of various kinds.
4. Economical consumption.
5. Moisture resistance.
6. Versatility. The material can be used for exterior and interior work.
7. Frost resistance.
8. Water vapor permeability.
9. Good indicators of soundproof and heat-saving properties.

The weight of the package, in which the dry mix "M-150" is produced is 50 kg.

Material Advantages

To the indisputable merits are manypositive properties. Among them is the opportunity to create an even layer. This is a very important factor when plastering, masonry walls and other works. On the surface of the finished layer, chips and cracks are not formed. But this is possible only if there have been no mistakes in the preparation of the solution and its application.

The high strength of the dried solution allowsUse the material of this brand when laying a stone, both artificial and natural. After solidification, the entire area on which the solution was applied remains uniformly dense.

In addition, due to the fact that the mixture is highly frost-resistant, it can be used in all regions of the country, including in the northern regions.

Characteristics of composition

Mixture dry universal "M-150" - a material consisting of several components, taken in the amount prescribed in GOST No. 28013-98.

It:

1. Portland cement. The brand of the material is "PC 400D0". It does not contain any additives.
2. Portland cement. The brand of the material is "PC 500". Contains mineral additives D20.
3. Fractional sand. The dry combined substance contains particles with a range of 0.1-1.2 mm.
4. Modifying polymer additives. They are needed to improve the astringent properties and overall quality of the material.

But that the cement mass has preserved its properties,it must be stored correctly. The best place for this is closed dry premises with a temperature of 7 to 35 ° C. The maximum permissible humidity during storage is not more than 70%. But even in such favorable conditions, the material should not be stored for more than 6 months, otherwise it will start to lose its properties.

Application features

Like any other material, it requires specialtreatment and "M-150". Dry mix should be consumed after kneading maximum after 2 hours, otherwise it will harden and become unsuitable for application. Therefore, it is necessary to take care of the preparation of the surface in advance. It must be cleaned of any contaminants. Lubricating oils, grease, dust and other similar substances will reduce adhesion, and a qualitative connection is unlikely to work. In addition, you need to remove those areas that crumble. If there are mosses, algae, fungus infection, they must be removed, and the infected surfaces should be treated with any of the fungicidal preparations.

Those surfaces that absorb fluids,must be treated with a primer. Another way out is multiple humidification, but every subsequent time it is necessary to moisturize only after the previous layer has completely dried.

Preparation of the mixture:

1. In the container for kneading pour the right amount of material "M-150". The dry mix should be distributed on the bottom, after which warm water is added to it. The proportion is 1: 5.
2. Stir the solution until the mass is uniform.
3. After 5 minutes, the mixing procedure is repeated, but the liquid is no longer needed.

Scope of use

The mixture is intended for finishing works ondifferent surfaces. It can be ceilings or walls, on which in the future will be done putty, wallpapering or painting. But this is not the whole list, where the "M-150" is used. The dry mix is ​​used for the following purposes:

1. Installation and styling.
2. Alignment of surfaces in reinforced concrete forms and different structures.
3. Concreting.

And the mass can be applied to concrete, cement-lime, cement-sand and brick surfaces.

Expenditure and Acquisition

Uninformed consumers are usually interested,how much you need to buy material for work, if you use a dry mix of "M-150". The expense depends on the type of work performed. For example, one square meter. m square it will take about 20 kg of the finished solution if it is applied with a layer 1 cm thick.

If it is brickwork, then the results are completely different, because they depend on the thickness of the masonry material. The number is indicated in 1 sq. M. m:

1. Half of the brick is 25 kg.
2. One brick - 50 kg.
3. One and a half bricks - 75 kg
4. Two bricks - 100 kg.

On sale there is plaster, erection-masonry anddry mix "M-150 universal". 50kg weighs the packaging of any kind of substance: it is convenient for transportation, storage and use, but some manufacturers also produce 25kg bags. Which option to choose depends only on the volume of upcoming works and on the manufacturer's rating. If the latter does not inspire confidence, it is better not to save money and turn to proven brands.
