8.3.3. Preparation for glass installation
If at glass removal the paint and varnish covering of a framework of glass on a body its structure is necessary for restoring is damaged and if necessary take measures on anticorrosive protection as directed volumes «technology of processing of surfaces / chemical substances».
At repeated installation of the intact glass the glue-hermetic which has remained on glass and a framework of glass, exactly cut off an electroknife and a knife-scraper, but at all do not delete completely.
The remained layer serves as a jet ground for drawing of a new layer of glue-hermetic.
Protect a sticky surface from a dirt and oil.
The glue rests cut off directly ahead of glass installation.
Do not process a surface of glutinous connection праймером, a cleaner.
At installation of new glass
Clear glass in a zone of gluing by means of D 009 401 04 and process праймером for glass and varnish D 009 200 02.

Праймер should settle down on the centre concerning the glutinous platen.
|Fig. 8.98. The sizes for glue drawing: 1 – the glutinous platen; 2 – праймер; 3 – a washer
The ceramic covering on glass is not праймером.
Surface before glue-hermetic drawing necessarily process праймером.
Width of the platen a = 8 ±2 mm
Platen height b = 12 +3 mm
The size c – it is necessary to consider various distance to glass edge.
