Protection of exterior walls from moisture

The brick wall looks like an insurmountable barrier to moisture, but this impression is deceptive. The fact that the brick has pores through which moisture can penetrate. Dampness can also go through is not very tight connection between the individual bricks and get to the inner wall surface. Thus, the penetration of water in the home is possible even in cases where the house used in the construction of dense bricks, concrete blocks or stone.

Thus, the penetration of water in the home is possible even in cases where the house used in the construction of dense bricks, concrete blocks or stone. Moisture which has penetrated through the walls, floors and destroys other parts of the tree. Moreover, the heat loss during damp walls 50% higher than the losses in the dry. Thus, the external waterproofing home is very important task. The best defense may be a layer of plaster, cement prepared on a basis or a special protective coating. The first method is more difficult to implement, but much cheaper. The plaster is put in two or three layers, its outer surface can be given a different kind of flat to hilly structure. Exterior wall is largely determined by the home owner tastes, but the number of layers depends on the rate of absorption of moisture. If the clutch cover with the wall is good, it is sufficient to apply two coats, in the case of weak coupling should apply another thin layer with a rough surface, which will serve as the basis for laying the other layers. This layer is applied as in the case if the wall has an increased ability to absorb moisture. It is recommended to do a simple test: drizzle water on the wall and look like a wall absorbs moisture. If water runs off in drops, then the wall repels moisture, otherwise the water soaks into the wall almost immediately. Determining the number of layers to be deposited on the wall, prepare the surface of the work. Wall should be cleaned from dust, mold and other things that will interfere with the tight coupling with a covering, and the same applies to the solution between the bricks. If you doubt that will be able to perform stucco work, we can simplify the problem and consider only painted the walls outside. The cheapest is the so-called cement paint that is sold in powder form, and before use is mixed with water. You can also put on the wall of the emulsion, which has the advantage that it is easy to put and dries quickly. The emulsion has a water repellent and may further serve as a basis for application of subsequent layers. It should be borne in mind that the paint and emulsion applied to a dense and thoroughly clean surface. If during the works on waterproofing the walls of undesirable change in the appearance of design, we recommend using clear seals. These seals are applied by brush or by spraying, clogging the pores of brick, they warn the penetration of moisture. In strict adherence to the manufacturer's instructions specified coverage is for 10 years if the wall has pores are too large diameter, it should apply a second layer of sealant. Do not forget to use such substances repaired all the cracks and potholes. Update joints of brickwork
