Today, there are many dry mixes on the construction market designed to greatly facilitate and speed up the workflow. The basis for their manufacture is cement and sand, to which, in order to improve the technological properties of ready-made solutions, plasticizers are added in production. The consumer only needs to open the package, pour out the required amount of material, add water and knead until a homogeneous mass is obtained.
One of these materials is "M-150". The dry mix of this brand is produced for different types of work - installation, laying, finishing.
Features
Due to the use of special technologies in production and the optimal ratio of components, the material acquires unique qualities that are extremely important and necessary for repair work or construction. This is:
- Reliability.
- High quality.
- Excellent adhesion to all kinds of bases.
- Economic consumption.
- Moisture resistance.
- Versatility. The material can be used for outdoor and indoor work.
- Frost resistance.
- Vapor permeability.
- Good sound insulation and heat-saving properties.
The weight of the package in which the dry mix "M-150" is produced is 50kg.
Material advantages
The undeniable advantages include a lot of positive properties. Among them is the ability to create an even layer. This is a very important factor in plastering, laying walls and other works. Chips and cracks do not form on the surface of the finished layer. But this is only possible if no mistakes were made during the preparation of the solution and its application.
The high strength of the dried mortar makes it possible to use the material of this brand when laying stone, both artificial and natural. After hardening, the entire area to which the solution was applied remains evenly 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 the northern ones.
Characteristics of composition
Dry universal mix "M-150" - a material consisting of several components, taken in the amount prescribed by GOST No. 28013-98.
This is:
- Portland cement. Material grade - "PC 400D0". It does not contain any additives.
- Portland cement. Material brand - "PTs 500". Contains mineral supplements D20.
- Fractional sand. The dry combined substance contains particles in the range 0,1-1.2mm.
- Modifying polymer additives. They are needed to improve the binding properties and the overall quality of the material.
But in order for the cement mass to retain its properties, it must be properly stored. The best place for this is closed dry rooms with a temperature of 7 to 35 ˚С. Permissible maximum humidity during storage - no more than 70%. But even in such favorable conditions, the material should not be stored for longer than 6 months, otherwise it will begin to lose its properties.
Application features
Like any other material, "M-150" also requires special handling. The dry mix must be used up after mixing for a maximum of 2 hours, otherwise it will harden and become unsuitable for application. Therefore, it is necessary to take care of surface preparation in advance. It must be cleaned of any contaminants. Lubricating oils, grease, dust and other similar substances will reduce adhesion, and a quality connection is unlikely to be obtained. In addition, you need to remove those areas that crumble. If there are mosses, algae, fungus damage, they must be removed, and the infected surfaces should be treated with any of the fungicidal preparations.
Those surfaces that absorb liquids must be treated with a primer. Another way out is to repeatedly moisten, but each subsequent time it is necessary to moisten only after the previous layer has completely dried.
Mix preparation:
- Pour the right amount of material into the mixing container"M-150". The dry mixture should be distributed along the bottom, after which warm water is added to it. The proportion is 1:5.
- Stir the solution until the mass is homogeneous.
- After 5 minutes, repeat the mixing procedure, but no more liquid needs to be added.
Use area
The mixture is designed for finishing work on different surfaces. These can be ceilings or walls, on which puttying, wallpapering or painting will be carried out in the future. But this is not the whole list where the M-150 is used. Dry mix is used for the following purposes:
- Installation and installation.
- Alignment of surfaces in reinforced concrete forms and various structures.
- Concreting.
Moreover, the mass can be applied to concrete, cement-lime, cement-sand and brick surfaces.
Expense and purchase
Uninformed consumers are usually interested in how much material needs to be purchased for work if the dry mix "M-150" is used. The cost depends on the type of work being done. For example, for one sq. m area will need about 20 kg of the finished solution if it is applied in a layer 1 cm thick.
If it is masonry, then the results are completely different, because they depend on the thickness of the masonry material. Quantity indicated per 1 sq. m:
- Half brick - 25 kg.
- One brick - 50 kg.
- One and a half bricks - 75 kg
- Two bricks - 100kg.
There is a plaster, masonry and dry mix "M-150 universal" on sale. A package of any kind of substance weighs 50 kg: it is convenient for transportation, storage and use, but some manufacturers also produce 25 kg bags. Which option to choose depends only on the amount of work to be done and on the rating of the manufacturer. If the latter does not inspire confidence, it is better not to save money and turn to trusted brands.
