Features of the universal dry mix М150

Today, a sufficient amount of dry mixes are produced to speed up construction processes. Usually they are made on a cement basis with the addition of sand and various plasticizers, all work with them comes down to adding water and stirring to the desired consistency. Next, we will consider the features of the universal dry mix M150.

Dry universal mix M150 is intended for masonry, installation and finishing works. One of its main properties is the creation of an even plastic layer, which is necessary for construction, installation, brick laying, plastering. It is usually produced in bags of 50 kg, less often of 40 or 25 kg; for preparation, you just need to dilute it with the required amount of water indicated on the package and stir with a mixer.

Due to the presence of plasticizers and other components in their effective ratio, dry universal mix M150 has the following advantages:

• reliability and excellent quality;
• the ability to adhere to many surfaces;
• frost resistance;

• economical consumption of material;
• good vapor permeability;
• moisture protection.

There are several varieties of the universal mixture M150, which differ in composition and purpose.

• Plastering the variety is intended for manual or machine application of plaster, the layer thickness can be from 5 to 50 mm. It is suitable for facade and interior work. After mixing, the composition retains its useful properties for 120 minutes, so you must immediately start applying the plaster or not knead large volumes. The applied composition acquires full strength after 28 days.

• Masonry M150 mixture is used for masonry of clay, silicate, refractory bricks, gas silicate blocks. It has high frost resistance, so you can work with it outdoors in all weather conditions. The composition can also be used in rooms with high humidity.
• M150 mixture for screed used for leveling the floor in various rooms. The layer can be from 1 to 10 cm, it is best to use a solution with beacons. With a layer thickness of 1 cm, the consumption of the dry mixture is 22-25 kg per 1 sq. m. The advantages of the M150 mortar for the screed are that, thanks to the concrete base, it turns out to be strong, resistant to moisture and temperature extremes.

Almost all manufacturers of dry mix M150 have the same composition, it includes:

• Portland cement grades PC400, PC500;
• dry sand with a fraction of 0.1-1 mm;
• mineral powder with a fraction of 0.1-0.5 mm;
• mineral additives and organic plasticizers.

All domestic manufacturers produce M150 mixtures in accordance with GOST 3051597, sand is used in accordance with TU 5711-002-05071329-2003.

The specific gravity or density of the cement-sand mixture M150 is 900 kg per m3, the consumption is 16-17 kg per 1 m2 with a layer thickness of 1 cm, the color is gray, the pot life is no more than 2 hours, the adhesion to the base is 0.6 MPa, the compressive strength is 15.

Mortar M150 differs from M300 or M400 in that it can be used to produce not only masonry, but also screed and plaster.Only the proportions of dilution with water and methods of use will be different. It is only necessary to dilute the mixture with cold water.

The method of application of the M150 product is as follows: a mixture of 1.8-2 liters per 10 kg of dry composition is poured into a container with water and then mixed with a mixer or manually until a homogeneous mass is formed. After the solution is diluted, it must be used within 2 hours.

With brickwork, the diluted mixture is applied in an even layer on the surface of the brick with a trowel and then leveled. The optimum thickness of the joints is from 1 to 5 mm, depending on the size of the blocks. When plastering, the solution is applied to the surface with a spatula, trowel or using an aggregate (plastering station), then pulled out with a rule to an even layer. Before plastering, the wall should be covered with a deep penetration primer, if the layers are more than 3 cm, then it is necessary to install beacons in advance.

Due to its popularity and versatility, the M150 building mixture is produced by a huge number of manufacturers. Almost every region has its own factories producing this product and its own well-known brands. There are even dozens of manufacturers in some cities. Nevertheless, it is worth noting the most famous and popular domestic brands known in Russia and the CIS countries.

• Manufacturer "Stone Flower" produces various types of dry mixes for assembly, repair and finishing works, among them M150 in bags of 40 kg. Consumption for 1 cm layer is 15-17 kg per 1 m2. The solution can be used with concrete, brick, stone surfaces at temperatures from +5 to +30 degrees. There is an opportunity to purchase packaging of 25 kg, 50 kg. Positive reviews are given for the "Stone Flower" products made of high-quality Portland cement and dry sand.

• Domestic manufacturer "Rusean" produces mixes M150 in portions of 40 kg. They are great for grouting, floor screed, plastering. In production, modern technologies are used, the mixture undergoes quality control and certification. Consumption is relatively economical - 1.5-1.7 liters of water should be used for 10 kg of dry mixture. After mixing, the initial setting occurs in 45 minutes, the solution completely hardens in a day.
• Sand cement M150 from the manufacturer "Ivsil" has proven itself in the building materials market. There are 3 types of products: plastering, masonry and universal. All brands are available in 50 kg bags, for this volume you need to use 9 liters of water. Among the advantages of the universal building mixture "Ivsil" can be noted a wide range of operating temperatures from -50 to +60 degrees, increased viability - up to 3 hours, strength and frost resistance - up to 50 cycles.

• Dry mixes "Prestige-S"made of Portland cement PC400 are used for a variety of construction works. They are used for masonry, screed, concreting, grouting, ceramic and paving slabs. The strength of the composition is 150 kg per 1 cm2, frost resistance - 50 cycles, consumption per 1 sq. m with a centimeter layer - 17-19 kg of dry mix. Products "Prestige-S" are manufactured with quality control, there is a guarantee for building materials.
• Domestic manufacturer "Osnovit", in addition to many other high-quality building materials, offers dry mixes M150 based on high-quality Portland cement PC500 and mineral additives. The advantages of the products of this company are durability and quality assurance. Mixes M150 "Osnovit" are supplied in 25, 40 and 50 kg packaging in very colorful bright packaging, which can be immediately distinguished.

• It is very important to choose a trusted manufacturer of M150 sand cement. Despite the fact that the composition of all these products is almost identical, the physical properties can differ significantly, for example, in the grain size of cement or sand, frost resistance, the presence of impurities and other factors. Therefore, buying a mixture of M150 cheap does not mean profitable.It is necessary to carefully study the composition on the packaging, its warranty and shelf life, purchase only from those manufacturers who have reliably proven themselves in the building materials market.

• After purchase, the M150 mixture must be stored closed in a dry and dark room with a temperature of +10 to +35 degrees and a relative humidity of no more than 70%. Under such optimal conditions, the product retains its properties for 6 months; it is not recommended to store it without use any longer.
• For the most effective use of the solution, the surface on which it is applied must be cleaned of large irregularities, fungus, mold, moss. This will ensure better adhesion and less material consumption. It is also always recommended to prime the surface before use.
