Before the insulation, the following points should be considered :
All surfaces that are supposed to be protected with moisture insulator should be soft, clean and dry.
All surfaces should be sloped towards the canals so that water does not accumulate at the surface of the insulation. Slope% 5 is recommended.
The installation of moisture insulator should not be carried out at an ambient temperature of less than + 5 ° C and not more than 40 ° C.
Avoid opening rolls and installing them in inappropriate air, i.e; hail, rainy, snowy, stormy weather (figure 1).
Insulation mounting equipments
Including liquid gas (capsule), a standard flame spreader, washbasin, a cloth razor, a spark igniter, a leather padded gauntlet, a rubber-driven handle, a broom, a smooth shoes (Figure A)
Reminder: The use of moisture installation airborne soundproofing devices is also permitted.
aid Installation materials
In order to improve the quality of insulation and the two-phase separation between the concrete surface and the moisture insulatior, it is recommended to use the proposed primer of the Alborz Arghavan Insulating Company’s technical Unit, depending on the installed surface.
When using the aid installation material, it should be noted that at least 24 , ,hours after applying the surface, it should be allowed to be completely dry.
How to open the roll
Cut the roller with a razor blade before releasing the insulation top , then remove the plastic film and separate it from the insulating surface in accordance with the following steps.
(As shown in the figure below)
The roll is ready after installation of the plastic film, so roll it down and follow the installation process.
Reminder: Installing moisture insulator is always possible with a plastic film with a thickness of not more than 0/1 that does not reduce the insulation tightness of the work surface.
If the surface of the work is mosaic, first make it smooth with cement and two concrete cavities.
If there is ridges such as the end of the rebar or the head of the column, or any sharp objecton the surface , then cut it and align it with the level of work.
Before installing, all the corners and rounded corners with 90 ° angle should be tightened with cement. Insulation should not be done on 90 ° angles.
Surfaces in the middle of which it is located should be in accordance with the shape of a section and ready to be installed.
The surfaces where the gates are in quadrangles must be in accordance with the shape of the two sections and be ready to be installed.
Remove all metal objects such as cooler, expansion spring, four free metal foundations on the surface and water supply sources without damaging them from the work surface.
