New editions of draft standards for adhesives and putties have been published

The purpose of developing the first edition of the standard " Dry construction putty mixes on cement binder. Technical conditions " - creation of a new document regulating the technical requirements for dry construction plaster mixes intended for external and internal work.

The draft standard is developed taking into account the international experience of rationing in the field of dry building mixes and sets technical requirements for a modern range of dry plaster mixes based on cement binder.

According to the expert opinion, the draft standard is characterized by a high level of harmonization with the standard " Construction mortars for masonry. Technical specifications. Part 1. Construction mortar for applying spray and plaster" and is linked to the interstate standards GOST 31189 " Dry construction mixtures. Classification", GOST 31157-2007 " Dry construction mixes. General technical conditions", GOST 31156 " Dry construction mixes. Test methods". The draft standard was publicly discussed, and all reasonable comments from interested organizations were included in the draft.

Another document is the second edition of the draft standard " Dry construction adhesive mixtures based on cement binder. Technical specifications". The object of standardization of this GOST R is the classification, terms and definitions, requirements and test methods for dry building mixes of adhesives on a cement binder. Glue mixes are widely represented in the construction market of dry mixes in Russia, each participant of which offers a range of adhesives from 3 to 8 names. This standard is developed on the basis of a number of interstate standards for dry building mixes and the European standard EN 12004-2007 and is unified with it in terms of classification of adhesive mixes, acceptance rules and test methods.

This standard is designed to provide manufacturers of dry mixes in Russia with technical requirements and test methods for their products that allow them to obtain similar results with EU countries for a comparative assessment of the construction and technical properties of tile adhesives in the process of scientific, technical and economic cooperation.

The full texts of both documents can be found on the website of the Union of Manufacturers of Dry Building Mixes.
