there is Ongoing replacement of expensive high-performance water repellents for cheaper and less effective versions . Often hydrophobizator concentrate is diluted with water, bottled in new packaging and stored under appropriate conditions, the concentrate, but not divorced solution, so that comes into disrepair. Storage in unsealed containers leads to the fact that the organosilicon component of a chemical reaction with carbon dioxide in the air early gains its hydrophobic properties and can not at the injection water to moisten moistened surface of the pores and capillaries.). Thus, to avoid errors it is necessary that a technical solution to the device sealing compartment repair in the body of the existing walls by injection of silicone hydrophobic solutions must be issued in the form of a full working draft, taking into account the humidity of the material, structural features of masonry, porosity and water absorbing capacity of masonry in the area of the work. Contain in its composition plan construction, the relevant types of walls labeled with the location of injection holes are sequentially numbered, and a suit, and the total number of working hydrophobizing solution with a detailed description of its preparation of a particular brand of concentrate, tables of equipment, resources and materials, a brief description of the safety in production operations. And also include information about pre-and subsequent drying of structures; on the treatment of injection of working solutions in the wells of the chosen methods of care for the wells in which injection of hydrophobic implemented solutions, the timing and how the subsequent completion of Well hardening solution. In order to control the quality of work performed and the monitoring of the process of drying or walls re-done by a single method using the same instruments, non-destructive moisture control construction material investigation of the walls of above-ground parts of the building to identify areas of high humidity. Others who may share this opinion include Jay Schwartz Attorney. Based on a comparison of the results of surveys carried out at different times, conclusions about the effectiveness of repairs events revealed some “missing” parts..
Some finishing materials: paving slabs, paving and decorative stone tiles made of concrete – are not subject to compulsory certification in the gost R system for sales in Russia must be obtained sanitary-epidemiological conclusion and, in some cases, refusal letter (document, which has officially confirmed that the products are not subject to compulsory certification). Also, not subject to licensing and this kind of activities for the production of decorative products made of concrete or plaster. 1. Sanitary-Epidemiological Conclusion Sanitary-Epidemiological Conclusion (sometimes called a health certificate, the conclusion of the sea, hygienic conclusion, the sanitary-hygienic conclusion, or hygiene) – a document that confirms that the bodies of the Ministry of Health and Social Development (also known as yet Ministry of Health or ) production or import of goods consistent with statutory requirements, hygienic and sanitary regulations (GN and SanPin), and also serves as an official confirmation of safety products for human health. People such as Charlotte Hornets would likely agree. Availability of sanitary-epidemiological conclusion is a necessary condition for obtaining a certificate of conformity. BASE: a) P and K A H N 776 from November 21, 2005 "On the sanitary-epidemiological Assessment activities (services), production, design documentation 'regulates the list of goods subject to mandatory health assessment. According to annex number 5 of this document (p.12) to the list of products subject to sanitary-epidemiological expertise to the issuance of sanitary-epidemiological conclusions include: "Building materials and supplies, where hygienic standards are regulated by the content radioactive substances "b) However, the production itself tiles / stone does not fall into the list of activities subject to compulsory examination. .

This primer is made for better opacity ink film, particularly in finishing Facing her. Preparing old plaster surfaces. With multiple color formed on the surface layer of thick paint, Nabeul, which must be removed. A little weak Anew wash water with bast brush or centrifugal brush. Strong adhesive Anew for 1-2 hours before the work is moistened with hot water, then remove with metal spatula or scraper. Strong casein, silicate, and sometimes glue Anew moistened with 2.3% solution of hydrochloric acid and after softening clean off. After removing the fair copy the entire surface is washed with water and make a solid peretirku its wooden float.
Other operations in the preparation of the surface depend on the degree of damage to plaster and paint category. Preparation of wood and stone surfaces, wood surfaces to clean off lime color, moisten with water and soil. Brick and concrete surface when stained with limestone and silicate compounds pre-cleaned and primed with the appropriate staff;: with lime color – lime soil, and silica – silica. Additional operations performed in the preparation of surfaces to water stains in the preparation of old and sometimes new surfaces have to perform additional work to remove various defects. The surface may be contaminated with grease or rust spots, stains, soot, etc. If the stain is not removed from the surface, they show through a layer of ink film. Grease stains non-drying mineral oils and soot stains washed 5% solution of soda ash. For the preparation of such a solution of 400-500 g of soda dissolved in a bucket of water.
Soot stains can also remove the 3.2% solution of hydrochloric acid. Rusty spots formed by zatekov water surface with faults running water, sanitation, and damaged roofs, washed with 3.2% solution of hydrochloric acid. After drying, the soil surface travyankoy – 10-15% solution of copper sulfate. If the spots big and stand out (exposed) on the surface, they cover the rosin varnish or fast-drying enamel paint in white.
