Medieval buildings in our modern cities surprised many people in the country for its strength and durability. The secret of this - high-quality building materials and special materials, which were used by masters of the time. It can be argued, that modern technology has also improved, and hopefully, that modern buildings and facilities will not concede under the characteristics of ancient buildings. For, to build a building, need high-quality mortar.

Features quality solution for masonry
- Plastic. Tools for bricklaying (usually a spatula) mason dials the desired amount of solution and smearing it on the working surface of bricks. It should be evenly lie on this surface, but not run with it and do not take lumps.
- good adhesion. Adhesion to building materials must be excellent, and should provide strength. After drying, built wall should not be deformed due to the resulting precipitation, of wind, mechanical effects.
- frost-resistance. There masonry mortars, which can be used at low temperatures (Typically, such construction materials have an identification mark "snowflake"). Moreover, any mortar must withstand subzero temperatures during operation, especially temperature changes.
- ease of preparation. Any solution for masonry you can prepare yourself, using the required components. But more efficiently, if you use ready-made mortar, which only need to be transferred from the state of powder in a solution state.
- Versatility. mortar It must be suitable for laying bricks, silicate blocks, foam blocks, porous brick.
Components masonry mortar
Their three - cement, sand and polymeric substances modifiers. The basis of the solution - Cement. This viscous substance, which after solidification is converted into a solid mass. To this can be added lime or clay, increase the viscosity and plasticity of the composition.
The second component is a solution of sand. A wrong, it can cause the appearance of lumps and various inclusions composed. This will negatively affect the process of laying, since the composition is not homogeneous.
Polymer modifier substance - a third component. They are added to enhance the life of the composition of life, increase time "setting".
