How to control the quality of the repair

Unfortunately, today, many builders work is not carried out as provided for in the work plan, but as faster and more convenient.

And a rare construction company can recruit the required number of skilled workers. Therefore, it is necessary to control the process of repair work. And for this you need to know some of the nuances and norms of repair work.

Plastering surfaces

Plastering today is the most common type of finish, and in the process, it is necessary to monitor the implementation of the following standards for plastering.

The working surface must be cleaned of dirt, grease and exposed salt. The protruding parts and the joints of structures made of various materials are plastered on a mesh attached to the surface. The tree is plastered on a shield of drani. The walls are plastered with ordinary cement-sand mortars or gypsum mixtures with a polymer additive.

When plastering with simple plaster, the thickness of the layer to be laid is 12 mm, with improved plaster - 15 mm, when using high-quality plaster - 20 mm.

On smooth stone walls, the layer thickness is 10 mm, on concrete - two to three millimeters.

Norms and requirements for laying tile

If the tile is laid on a cement-sand mortar, then the thickness of the applied layer should be from seven to fifteen millimeters. The proportions of sand and cement in the cement mortar - 4: 1. When laid on tile adhesive, the layer can be from 5 to 40 mm. If the tile rests on adhesive mastic, the layer is one to two millimeters.

When laying tile outdoor, the deviation from the vertical per meter of length should not exceed two millimeters. When laying inside the building, the deviation should not be more than one and a half centimeters.

When laying tile, irregularities on the laying surface should not exceed a couple of millimeters. When laying outside irregularities should not be more than 3 mm. The deviation of the thickness of the seam between the tiles varies within 0.5 mm.

The result of laying tiles must meet the following requirements:

• The space between the tile and the wall must be filled with mortar;
• The seams between the tiles should be the same and uniform;
• There should be no cracks, leaks or stains.

Plumbing work

When performing plumbing, remember that they should not spoil the water supply system of your neighbors.

For plumbing, it is allowed to use pipes made of plastic and metal plastic, as well as bronze, copper and brass pipes with an anti-corrosion coating. If hot and cold water are laid together, then the hot water pipe It is recommended to isolate it with a special thermal insulator and place it over the water supply for cold water.

Plastic pipes must be hidden in plumbing channels and shafts. Open laying of a plastic pipe is permissible only in places where mechanical damage is not possible. Concealed laying of a steel pipe connected by a thread is not allowed.

Mixing and stop valves should smoothly open and close the flow of water, and is set to a working pressure of 0.6 megapascals.

When installing the bath, the future floor level must be taken into account. The bath must be grounded.

The entire water system must be checked at maximum water pressure, preferably before laying tile and installing a bathtub and sink. By the way, after the repair is over, do not forget to pay attention to such a procedure as garbage removal, because this is a very time-consuming process.
