If your home is built on a wet plot, then you are precisely familiar with such problems as cracks on the foundation, settled in the floor of the fungus and mold. Protects waterproofing from these troubles. We will learn about the types and basic rules for drawing the coercive waterproofing by reading this article.

Pros and cons of coating waterproofing
Waterproofing The coating usually consists of several layers. Thickness can be equal to both multiple millimeters and several centimeters. It depends on what state is the surface being processed.
Advantages of coating waterproofing
- protects houses both from the inside and outside of groundwater, steam;
- increases the durability of buildings;
- work on its application is simple and can be made with their own hands;
- the protective surface is homogeneous, butts are missing;
- the possibility of applying to any surface;
- cheaper than other insulation materials;
- work takes a little time.
disadvantages
- bad resistance to mechanical effects;
- the waterproofing properties are lost if the motorway is passed by the house or near the railway station, or the construction of the high rise has been launched.
Types of coating waterproofing
The following compositions are used as coating waterproofing:
- based on bitumen. The cost of such waterproofing is low, but there is a significant drawback: it is fragile at low temperatures. When laying bitumen coating waterproofing, it must be heated to 120 degrees C. serves no more than 6 years. Among other types - this is the cheapest;
- waterproofing a coating having a bitumen-latex basis. It is plastic, heating during laying is not required, in the application is simple, fireproof, but in some cases, the basis must be reinforced;
- based on synthetic resin. Called bitumen polymer. Very high-quality, durable, working with it is possible at minus temperatures up to -50 degrees C. deeply penetrates the surface to be processed. Before use requires scrupulous preparation and pre-primer;
- cement. It is economical, environmentally friendly, crazy, durable and easy to use. There is also: We need work skills, otherwise it is difficult to apply it;
- mastica cement-polymer. Cement and synthetic components provide it with high adhesion with the surface and bending resistance, so it is used on overlaps. The surface before applying is prepared. The price of her is quite high.
Waterproofing foundation
The waterproofing of the foundation is necessary to perform in any case, since it accumulates moisture from the soil, which is capable of destroying it.
What material to choose
When choosing waterproofing, you need to decide:
- with a temperature regime that will prevail during the period when you are going to work;
- where you will apply the material: from the outside, or isolate the foundation in the basement;
- with an area the size that you want to isolate. On the basis of space, determines the flow rate;
- with loads of the treated part of the foundation.
The types of waterproofing materials used for the foundation
Builders professionals waterproofing divided into 3 types. One protivokapillyarny and the other two - protivovodnye:
- easy. It is used where the groundwater is below the foundation level. Soils in this case are most often sandy or sandy. The role of this waterproofing is to protect the foundation from capillary moisture;
- average. Designed for foundations erected on clay and loam, which long stored moisture, not giving to go to the depth;
- heavy. The use of this type of waterproofing is advisable where groundwater is high and have a constant pressure on the foundation. At least 4 mm layer apply this defense. It is necessary to reinforce the fiberglass mesh in 2 layers.
Note: On some packages, the classification of the material used by experts can be specified.
Rules for applying lubricant waterproofing for the foundation
By purchasing a liquid waterproofing mixture, perform all the conditions specified by the manufacturer, and besides:
- we apply waterproofing with a brush, roller or spatula;
- if it rained, then go to work at least 4 hours;
- the surface of the foundation is as possible, we remove sharp edges in order not to disrupt the coating tightness;
- if it is anti-capillary waterproofing, then apply it with a layer of 1 to 3 mm;
- a medium-type waterproofing layer sometimes reaches 5 mm;
- depending on the characteristics of a severe waterproofing mixture, it is layered with a layer of 2 to 6 mm;
- watch the layer to have the same thickness throughout the area;
- at hours 10-12, the layer is needed to protect something from the sun or possible rain, and when it grabs a little, the protection is cleaned. Complete drying occurs after 2-3 days.
Important: In the process of applying waterproofing, it is necessary to control its thickness. Measurements should be performed pointwise diagonally.
We protect waterproofing
When the backflow of the pit, the risk of waterproofing is made, therefore it is better to protect it, while: if the waterproofing mixture does not contain organic solvents, then extruded or ordinary polystyrene foam for light and medium waterproofing and a profiled membrane is used as protection. 
It is successfully used for coating waterproofing of the foundation Waterproofing mixture Kreisel Dichtungsschlämme 810. It is made in Germany:
- used both outside and inside;
- divorced water. After cooking, it is necessary to implement within two hours;
- applied at a temperature of from 5 to 25 degrees C;
- made based on Portland cement. Contains additives in the form of polymer binders, mineral fillers, modifiers;
- to dry out the first layer, it takes an hour 3. For the following layers, the time may increase by 1 hour;
- focusing on the operating conditions, applied a layer from 2 to 5 mm;
- the quality of waterproofing will increase if it is applied before applying it, to primitive the surface of the acrylic facade primer from the same manufacturer.
Caution waterproofing floor
The coating waterproofing on the floor will save the house from dampness, and if it is an apartment, it is necessary in the bathroom and as protection against moisture, and like armor from flooding your neighbors.
Preparatory stage
With the move to apply isolation is not worth it. At first:
- we clean the surface: we remove the dust with a vacuum cleaner, we clean the floor from all extraneous spots, because due to them the adhesiveness can worsen;
- be sure to align. Permissible irregularities only up to 2 mm. If there are large slots, then we cement them;
- we establish lighthouses and make an aligning screed bands with a width of 2-3 m;
- when the screed grabbing, we apply primer using a brush or sprayer;
- if you have chosen a coating waterproofing for the floor in the form of a dry mixture with a cement basis, then to split it in water. The proportions are on the packaging. After 5 minutes, the solution is again stirred. It must be homogeneous.
Applying coating waterproofing
It is necessary to use a mortar on a cement basis for 1.5 hours, so immediately proceed:
- we apply the first layer;
- after 5 hours, you can proceed to apply the second layer. At the same time, we impose it perpendicular to the first to the first, the lumens between the smears are minimal;
- if the coating waterproofing of the floor is performed on a bitumen-latex or bitumen-polymer basis, then the screed is poured over it.
In order for the purchase of waterproofing, the price corresponds to the quality, choose the proven manufacturers. Good reviews about two-component waterproofing of coating elastic-plastic Litokol Coverflex from the Italian manufacturer Litokol:
- it has a good grip both with porous and dense surfaces;
- the basis is cement;
- resistant to chemical impacts;
- applied by two cross-layers. The interval between procedures is 3 hours, if the temperature is not lower than 23 degrees with;
- it is used in the range of temperatures of 5-35 degrees C;
- on the application of 1 mm layer of 1 m square. 1.6 kg of mixture leaves.
