Fasteners: dowels, screws, screws, etc. In houses with wooden beams used nonflammable wires or cables or NYA NG, such as VVGng or VVG NYA. The scheme runs of wiring necessary to think in advance and carefully. To do this, draw a sketch on paper – the scheme. In the scheme should take into account not only the ease of installation (minimum shtroblenie walls), but no power lines crossing each other. All electrical lines are routed only straight lines, either horizontally or vertically.

Laying scheme remains to exclude damage to the wiring future. For manufacturing use Stroebe disk grinding machine with a diamond cutting wheel. Nest boxes for the installation and setup raspayachnyh punch with punch. The wires are cut to match the length pave the road and placed in alabaster Stroebe and fixed every 25 … 30 cm mounting boxes installed as the solution of alabaster. Do not skimp on the length of the wires, preparing them for laying.

Length free ends of the wiring should be sufficient to easily perform all the necessary wire connections among themselves or with placing the device. To isolate the junction of the cable and wires better use of thermo shrink tube and electrical tape PVC. Please note that the wiring with wires of different metals in the stranding is prohibited. Aluminum and copper are not "friends" together. You can only connect through the terminal pads. The connections of wires and their branches should be placed in the junction boxes at all the options of wiring. All electrical appliances: the meter, sockets, switches, distribution boxes must be accessible, the switches must not hide behind a door at the entrance to the premises. Outlets are installed at a height of 0.8 m from the floor. Particular attention should be given the correct selection of sections laid by Wire protection devices and the choice of cable lines from overload and short circuit – breakers. RCD – Differential relays are installed to protect against electric shock by direct or indirect contacts with live parts of electrical machinery and electricity. Do not skimp on protection. Using advanced technology and quality assurance of many decades suggest guaranteed protection during the installation of circuit breakers and differential relays companies such as ABB, SIEMENS, Legrand, Hager. Some uncertainty arises when the Chinese and Turkish instruments. cable, wire, electrical wiring in the house and lighting in the apartment – an online store Voltus

Instead of the usual staining iron products may be coated with oil paints their colors (which include white), diluted with turpentine. Practice has shown that the first way is much worse than the last, since turpentine with whiting to better penetrate into the pores of the iron and thereby better protect it from damage by rust in the water and in air. The fact that at the present time for the facade materials are increasingly made of metal, plastic, glass, etc., in any case does not mean that traditional painting and decorative plaster has lost its meaning. Firstly they are very economical, and secondly – have more options of colors and textures, and, finally, they are indispensable for the reconstruction of old buildings that do not allow the use of fashionable cladding materials. Paints are a homogeneous suspension of pigments in the film-forming substances (binders). In addition to these the main components that determine the basic properties, purpose and use of paints may contain solvents, fillers, plasticizers, additives to different target.

The paint is applied to the surface of thin layers by brush, roller or paint sprayer to form the opaque film upon drying or porous coating to protect the painted surface from external influences (light, moisture, chemicals) and giving her beautiful appearance. When choosing colors for the customer are most important: a) Decorative coating properties (color, texture, gloss), b) Operational properties of the coating (resistance to washing, to mechanical stress, to polluting factors to weather and corrosive influences, maintainability, durability and protective properties), c) Specific requirements for coatings for specific functions, and d) cost of one m surface. For In order to meet these requirements, the professional finishers must convince customers to spend the whole complex dookrasochnyh events. The purpose of these events – to minimize the infiltration of moisture into the wall. Dookrasochnye activities include: repairing cornices, sills, gutter system, etc.

For older stains can be applied only silicone paint (see below), but it is necessary to calculate the cost-effectiveness, since they are significantly more expensive than acrylic. Technological and operational properties of acrylic latex paint to a large extent depend on the content of the binder. At sufficiently high quality paints the binder is at least 15% of the volume, and the colors of the highest class comes to 40% or more. But at the same time, one should bear in mind that the higher percentage of binder, the lower water vapor permeability of the coating. Another very important factor – the dry rest – for high-quality acrylic latex paints are not must be less than 45-50% by volume. Both of these indicators significantly affect the price of paint.

Cheap latex paint (less than 2 $ / kg) have a high flow rate (kg / m ) and low durability, so their use not economically justified. So, if you want to create enough high-quality, resistant to pollution coverage, which does not meet high standards for water vapor permeability, the use of acrylic paint most appropriate. If the coating to high demands for water vapor permeability (such as painting buildings with poor foundations waterproofing) is advisable to apply the paint from a mixture of acrylic copolymer with a variance silicone resin. In these cases also use silicone or silicate paint. Silicate paints are mineral paints. A small amount of polymer (less than 5%) gives them stability in storage and possibility of using a mono version.

Silicate paint adhesion to the substrate with a two-step chemical reaction. At the first stage of the binder – a liquid potash glass – reacts with carbon dioxide in the air, forming a silica gel. In the second phase silica gel by chemical reaction meshes with a stone base. To align the absorbency of the base paint is used under silicate silicate primer also based on liquid potash glass. Silicate paints are used exclusively for coating mineral surfaces, for example, mineral plasters and surfaces previously coated with lime, cement or silicate paint. As for the polymer, they prevent the adhesion of liquid potash glass with a base and, consequently, impair the adhesion of silicate paints. Therefore, the surface of the previously painted with acrylic or alkyd paints, pre-cleaned of traces of previously applied coatings.
