| Basic Important Facts : |
The consumption
of Gypsum Plaster is directly related to the line & level of the
walls in the building, which is a variable factor. It also depends upon
the basic wall base material i.e. Bricks/Blocks.
Based on field
trials & experience, the consumption pattern of Gypsum Plaster
varies between 1.5 kg. in a right angle finish on the walls.
It is advisable
to do a mock up of a entire flat in your building to ascertain the
actual consumption pattern of Gypsum Plaster. |
Guidelines For Application : |
- Fittings & plugging
should be done before plastering. Openings, chasing etc. (for fittings
or conduits ) should be filled firmly before starting plastering.
-
Entire background (to be plastered) should be thoroughly brushed & cleaned to remove dust, loose mortar & oil/grease.
-
The surface should be
reasonably dry & protected from weather conditions. The height
suction background should be adjusted by sprinkling water.
-
Always mix powder, not
water to powder. Material should be thoroughly mixed & stirred as
to insure it is free from lumps and impurities before use.
-
Once
plaster wet mix is made & has started to do set, it should not be
tempered with fresh mix or powder, as it will affect the properties.
-
Due care should be taken to ensure that rapid loss of water is avoided, in not & dry condition.
-
Tools & Water used should be cleaned & free from impurities.
-
To ensure that hands are dry before always fold open end of bag, to protect plaster from moisture.
-
Bags should be handled carefully to avoid tearing. Hooks are not recommended.
