Gluing additional layers of roofing should be done after installing the top layer of the roof, immediately after applying the adhesive mastic in a continuous layer.

2.21. When gluing panels of roofing carpet along the roof slope, the upper part of the panel of the lower layer must overlap the opposite slope by at least 1000 mm.

Mandatory when finishing and renovating an apartment; disputes arise between the customer and the contractor regarding the quality of the finishing work performed. The client claims that the quality is not very good, but the contractor claims the opposite. Such disputes could go on forever if building codes did not exist.

So, building codes and regulations that have stood the test of time and are approved by the state help resolve the controversial issue of the quality of finishing work. In technical language - these are standards - SNiP and GOST.

Here I have collected the most common standards for the quality of work performed when finishing apartments. All permissible deviations, slopes and irregularities can be seen below and finally understand the situation - who is right and who is wrong! In my work, when renovating an apartment, I fully adhere to all building standards and approvals. I strictly apply SNiPs and GOSTs for repairs and finishing works

The program given in these guidelines as an example is recommended to be used when predicting the service life of water-repellent compounds for natural stone cladding of curtain wall façade systems with an air gap, and also to be used as a base program when planning programs for other insulating and finishing materials.

A.1 Program planning algorithm

A.1.1 Determination of operating conditions taking into account SP 131.13330.

A.1.2 Determination of typical operating factors, their most unfavorable qualitative combination and the expected effectiveness of the material, taking into account the qualitative composition of the material and actual operating practice.

SP 71.13330.201X First edition A.1.3 Determination of controlled parameters for the selected material and their limit values, taking into account the current provisions of the relevant (or closest to the materials in question) regulatory and technical documents.

A.1.4 Program construction: determination of boundary conditions, their sequence and frequency of repetition of simulated climatic operating factors, taking into account GOST R 51372.

When planning a program, it is necessary to be guided by the principles of occurrence, periodization and mutual combination of climatic loads at critical points at a given period of time (relative), based on similar natural patterns (the sequence of changes in seasons and critical points of climatic influences characteristic of them).

When planning a program, it is recommended to compare and adjust the boundary conditions, their sequence and frequency of occurrence of modeled climatic operating factors, taking into account data on actual weather observations for the construction area in question over the past 5 years.

Systematization of such data is most accurate for the forecasting period during experimental-theoretical and computational-experimental modeling for a period of 5 to 25 years.

A.2 Program planning

The principle of program planning is presented using the example of a developed program designed to determine the estimated service life of water-repellent compositions for natural stone cladding of curtain wall façade systems with an air gap, operated in the city.

If, during climatic tests, the limit value was reached prematurely, the previous measurement of this parameter is taken as the final result and the predicted service life corresponding to it is established.
