Types and basic rules of applying coating waterproofing

If your house is built on a wet plot, then you are exactly familiar with such problems as cracks on the foundation, settled in the floor fungus and mold. Protect from these troubles waterproofing. You will find out about the types and basic rules of coating waterproofing by reading this article.

Pros and cons of lubricating greasewaterproofing

Waterproofing coating usually consists of several layers. The thickness can be equal to several millimeters, and several centimeters. This depends on the state of the treated surface.

Advantages of coating waterproofing

• protects the house both inside and outside of groundwater, steam;
• increases the durability of buildings;
• work on its application is simple and can be done by yourself;
• the protective surface is uniform, joints are absent;
• possibility of application on any surface;
• is cheaper than other insulating materials;
• work takes a little time.

Disadvantages of

• poor resistance to mechanical influences;
• waterproofing properties are lost if a motorway passes by the house or a railway station is near, or the construction of a high-rise has been started nearby.

Types of coating waterproofing

The following compositions are used as a coating for waterproofing:

• based on bitumen. The cost of such waterproofing is low, but there is a significant drawback: it is brittle at low temperatures. When laying the bituminous coating waterproofing, it must be heated to 120 degrees Celsius. Serves no more than 6 years. Among the other species - this is the cheapest;
• waterproofing coating, having a bitumen-latex base. It is ductile, it is not required to heat up when laying, it is simple in application, it is fireproof, but in some cases, the base must be reinforced;
• based on synthetic resin. It is called bitumen-polymer. Very high-quality, durable, work with it is possible and at minus temperatures to -50 degrees C. Deeply penetrates into the surface being treated. Before use, scrupulous preparation and preliminary priming are required;
• cement. It is economical, environmentally friendly, non-shrinking, durable and easy to use. There are also: skills are needed, otherwise it is difficult to apply it correctly;
• mastic cement-polymer. Cement and synthetic components provide it with high adhesion to the surface and resistance to bending, so it is used on ceilings. The surface is prepared before application. The price at it is high enough.

Basement waterproofing

It is necessary to waterproof the foundation of the foundation in any case, since it accumulates moisture from the ground, which is capable of destroying it.

Which material to choose

When choosing waterproofing, it is necessary to determine:

• with a temperature regime that will prevail in the period when you are going to work;
• where you will use the material: outside or to isolate the foundation inside the basement;
• with the size of the area to be isolated. Based on the area, determine the flow rate;
• with loads on the treated part of the foundation.

Types of waterproofing materials used for foundation

Professional builders divide waterproofing into 3 types. One of them is anticapillary, and the other two are anti-water: the

• is light. Applied where groundwater is below the foundation level. Soils in this case are mostly sandy or sandy loamy. The role of this waterproofing is to protect the foundation from capillary moisture;
• average. Designed for foundations erected on clay and loam, which for a long time store moisture, not allowing it to go to depth;
• is heavy. The use of this type of waterproofing is advisable where the groundwater is high and exerts a constant pressure on the foundation. Apply this protection to a minimum of 4 mm layer. It is necessary to reinforce the fiberglass mesh in 2 layers.

Note: on some packages may indicate the classification of material that is used by specialists.

Rules for applying waterproofing to the foundation

When purchasing a liquid waterproofing mixture, follow all the conditions stipulated by the manufacturer, and in addition:

• apply waterproofing with a brush, roller or spatula;
• if it rained, then proceed to work at least 4 hours;
• the surface of the foundation is as far as possible leveled, remove the sharp edges, so as not to break the integrity of the coating;
• if it is an anti-capillary waterproofing, then apply it in a layer from 1 to 3 mm;
• layer of waterproofing of medium type sometimes reaches 5 mm;
• , depending on the characteristics of the heavy waterproofing mixture, it is applied by a layer from 2 to 6 mm;
• make sure that the layer has the same thickness over the entire area;
• for hours 10-12 layer must be something to protect from the sun or a possible rain, and when he grabs a little, the protection is removed. Full drying occurs after 2-3 days.

Important: during the application of waterproofing it is necessary to control its thickness. Measurements should be performed diagonally.

We protect waterproofing

When backfilling of the excavation is performed, there is a risk of damage to the waterproofing, so it is better to protect it, if: if the waterproofing mixture does not contain organic solvents, then extruded or ordinary polystyrene foam for light and medium waterproofing and profiled membrane are used as protection,for heavy.

The waterproofing mixture Kreisel Dichtungsschlämme 810 is successfully used for the foundation waterproofing of the basement. It is produced in Germany:

• is used both outside and inside;
• is diluted with water. After preparation it is necessary to realize within two hours;
• is applied at a temperature of 5 to 25 degrees Celsius;
• is made on the basis of Portland cement. Contains additives in the form of polymer binders, mineral fillers, modifiers;
• for drying the first layer it takes about 3 hours. For the following layers, the time can increase by 1 hour;
• focusing on operating conditions, a layer from 2 to 5 mm is applied;
• the quality of the waterproofing will intensify, if before applying it, primed the surface with an acrylic front coat primer from the same manufacturer.

Soaking waterproofing of the floor

Soaking waterproofing on the floor will protect the house from damp, and if it is an apartment, it is necessary in the bathroom and as a protection against moisture, and as armor from flooding you neighbors.

Preparatory stage

Do not apply insulation. First:

• clean the surface: remove the dust with a vacuum cleaner, clean the floor of any foreign spots, because because of them the adhesion may worsen;
• always perform alignment. Permissible roughness only up to 2 mm. If there are large cracks, then we cement them;
• install beacons and make leveling screed with 2-3 m wide strips;

• when the screed grips, apply the primer using a brush or sprayer;
• if you have chosen a waterproofing coating for the floor as a dry mixture with a cement base, then dilute it in water. The proportions are indicated on the package. After 5 minutes stir the mixture again. It must be homogeneous.

Application of coating waterproofing

Use the cement-based mortar for 1.5 hours, so proceed immediately:

• apply the first layer;
• after 5 hours you can start applying the second layer. In this case, we superimpose it perpendicularly to the first one, so that the gaps between the strokes are minimal;
• if the floor waterproofing is carried out with a composition on bitumen-latex or bitumen-polymer base, then a screed is poured over it.

In order to purchase a waterproofing coating, the price is in line with the quality, choose the proven manufacturers. Good reviews of the two-component waterproofing lubricating elastic-plastic Litokol Coverflex from the Italian manufacturer Litokol:

• has good adhesion with both porous and dense surfaces;
• is a cement base;
• is chemically resistant;
• is applied by two crossover layers. The interval between the procedures is 3 hours, if the room temperature is not lower than 23 degrees Celsius;
• is used in the temperature range 5-35 degrees C;
• for application of 1 mm layer with an area of ​​1 m square.1.6 kg of mixture leaves.
