What is a dry mix?
Dry mixtures for waterproofing - a compound of binders, fillers and additives in the composition of which there are special components that provide penetration of the solution into the pores of concrete or brick walls, which creates a moisture barrier premises. As a rule, the dry mixture is diluted with water. Rationing occurs according to the instructions on the packaging material.
In the production of dry mixtures, only hydraulic binders are used, as well as fillers from rocks with high density and minimum moisture absorption. The technology of manufacturing such compositions contains the following aspects:
- sand drying and its fractionation;
- dosing of all necessary components;
- mixing;
- prepackaging of the finished product.
Dilute and apply the solution strictly according to the instructions on the label. If you do not follow the manufacturer's instructions, then later you can pay for the destruction of the concrete or reinforced concrete structure of the building. In addition, work on waterproofing buildings are considered to be one of the most dangerous jobs in the construction industry. This is due to the high reliability of the work performed. Classification
dry formulations
Dry mixes for waterproofing are divided into two types: a mixture, are used for the primary method of sealing of buildings, and mixtures secondary method. The primary method of sealing is the use of an enclosing structure made of reinforced concrete or concrete of the necessary resistance to moisture.
Secondary method - additional sealing of the enclosing structure. For this work, penetrating, lubricating, plastering waterproofing is used. All these types of waterproofing are used depending on the features of the construction of buildings and on the material to be applied to the solution.
Also the formulations for waterproofing are divided according to the size of the fillers. They are:
- solution;
- concrete;
- dispersed.
Important! The size of the maximum size of the filler determines the minimum thickness of the resulting sealant layer.
Scope of dry mixes
Dry mixtures for sealing surfaces are widely used in the construction and repair of buildings. Compositions are usually used for applying to a concrete, reinforced concrete or stone structure in order to avoid further exposure to moisture and other aggressive media that contribute to destruction.
Important! Before buying a dry mix, you need to calculate the amount of ready-made mortar needed to coat the surface.
Regardless of the manufacturer and type of dry mortar for sealing, its consumption averages 2-3 kilograms per square meter of surface. A more accurate figure of consumption can be obtained by reading the label on the package.
Only competent use of dry compounds for sealing, in compliance with all the recommendations and technologies of the manufacturer, guarantees you a high-quality and durable waterproofing of the required surface.
