INTRODUCED by TsNIIOMTP Gosstroy of the USSR.

PREPARED FOR APPROVAL by the Office of Standardization and Technical Standards in Construction of the USSR State Construction Committee (D. I. Prokofiev).

When using a regulatory document, one should take into account the approved changes in building codes and rules and state standards published in the Bulletin of Construction Equipment magazine, the Collection of Changes to Building Norms and Rules of the Gosstroy of the USSR and the information index "State Standards of the USSR" of the State Standard of the USSR.

1. GENERAL PROVISIONS

l.l. These building codes and regulations apply to the production and acceptance of work on the installation of insulating, finishing, protective coatings and floors of buildings and structures, with the exception of work due to the special operating conditions of buildings and structures.

1.2. Insulating, finishing, protective coatings and floor structures must be carried out in accordance with the project (finishing coatings in the absence of project requirements - according to the standard). Replacement of the materials, products and compositions provided for by the project is allowed only upon agreement with the design organization and the customer.

1.3. Work on the production of thermal insulation works can begin only after the execution of an act (permit) signed by the customer, representatives installation organization and organization that performs thermal insulation works.

1.4. The device of each element of insulation (roof), floor, protective and finishing coatings should be carried out after checking the correctness of the implementation of the corresponding underlying element with the preparation of an inspection certificate for hidden work.

1.5. With appropriate justification, in agreement with the customer and the design organization, it is allowed to assign methods of work performance and organizational and technological solutions, as well as establish methods, volumes and types of registration of quality control of work that differ from those provided for by these rules.

2. INSULATION COATINGS AND ROOFING

GENERAL REQUIREMENTS

2.1. It is allowed to carry out insulation and roofing work from 60 to minus 30 ° C of the environment (works using hot mastics - at an ambient temperature of at least minus 20 ° C, using water-based compositions without antifreeze additives not lower than 5 ° C).

2.2. In the bases for roofing and insulation in accordance with the project, it is necessary to perform the following work:

seal the seams between prefabricated slabs;

arrange temperature-shrinkage seams;

mount embedded elements;

plaster sections of vertical surfaces of stone structures to the height of the junction of a rolled or emulsion-mastic roofing carpet and insulation.

PREPARATION OF THE BASES AND SUBJECTS

INSULATION ELEMENTS

2.4. Substrates must be dedusted before applying primers and sealers, including bonding adhesives and mastics.

2.5. Leveling screeds (from cement-sand, gypsum, gypsum-sand mortars and asphalt mixes) should be arranged with grips 2-3 m wide along guides with leveling and compaction of the surface.

2.6. The priming of the surface before applying the adhesive and insulating compositions must be made continuous without gaps and gaps. Priming of screeds made from cement-sand mortars should be carried out no later than 4 hours after their laying, using primers on slowly evaporating solvents (with the exception of screeds with a surface slope of more than 5%, when priming should be performed after they have hardened). When preparing the surface of the base, it is necessary to comply with the requirements of Table. 2.

The primer should have a strong adhesion to the base, no traces of binder should remain on the tampon applied to it.
