Meet the mixture

The structure of masonry mortar in a specific ratio includes a binder and a filler material, most often it is the sand.These solutions have excellent adhesion and resistance to compression, allowing you to build the walls, which are designed for heavy loads.Buildings constructed using masonry mixtures, especially durable due to resistance to moisture and cold.Most plasticity occurs in limestone masonry mixes.Lime provides a solution good thermal conductivity, which is reflected positively on the atmosphere in the room.

If some of the technical indicators of the substance needs to be improved, that certain additives may be included in the composition.Thus, the addition of expanded clay improves the thermal insulation properties, and colored masonry mixture may be obtained by adding various pigments.Basic additives are used, this curing catalysts, plasticizers, and pigments for coloration.

Important!To calculate the necessary amount of additive should be referred to specialists.

As a mixture of masonry?

To a mixture of masonry gave the maximum effect, it is necessary to prepare well the surface to be coated.It should be dry and free of defects, cleared of all substances that may interfere with the adhesion surface of the solution.To prepare the mixture must be poured into a container with water rate of 200 grams per kilogram of substance.All this is mixed until a creamy mass.After that five minutes, the mixture is brewed, and then for two hours, it can be used.

technology use solution is to apply a uniform layer on the surface with a trowel.The mixture, which remained after the installation, removed and re-used.Flow masonry mixture averages 1.75 kilograms per square meter at a layer thickness of one millimeter.The optimum temperature for work from +5 to +30 degrees Celsius.The highest efficiency is observed when working in 20 degrees and humidity of 60%.

Note!If the temperature and humidity are not correct, then the hardening and setting times vary.

How to choose a good mix?

When choosing a mixture of masonry is necessary to pay attention to the following indicators:

  • strength;
  • plasticity;
  • Good adhesion;
  • high degree of water repellency.

strength depends on the binders in the composition.In addition, it is influenced by the base to which it is applied.Thus, the solution will be much higher strength when applied to the porous material, and when applied to the surface of dense contrary, it will be worse.

plasticity affect the ability to lay flat and thin layers of solution.Good ductility allows you to smooth out all the bumps on the basis of quality and adhere to its surface.In addition, this factor increases the working efficiency and quality of laying.

Good adhesion - is the quality of adhesion to masonry elements, to the separation and shear stability.The higher the adhesion, the greater the bond strength of all the elements together.Water repellency plays an important role during laying the solution onto the porous material.Also, this factor affects the stability of the mixture to phase separation during transport.Drawing attention to the quality of the mixture, you can be sure that you buy quality products.

Important! When buying a mixture of certified check, it will protect you from buying fakes.
