GYPTECH – Universal Plaster

|

Sand & Cement Plaster

Low Density | High Density
Low Thermal Conductivity and hence obstructs flow of heat. | Thermal Conductivity High compared to Vermiculite
Because of uniform porosity humidity is under control | Control of humidity is negligible
No cracks because of its resilient nature | Cracks may appear with appreciable changes in temperature
Excellent smoothness and whiteness improves the aesthetic appeal of the surface after painting | Additional costly treatments are required to get good smooth finish
No curing required. Painting can be taken up after 48 hours of complete drying. Time saving. | Requires two weeks of curing and surfacing. Time consuming.
Good sound absorption | Reflects sound

Guidelines for Application


Fitting & 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 high suction background should be adjusted by sprinkling water.
Always mix powder to water, not water to powder. Material should be thoroughly mixed & stirred as to ensure 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 hot & dry condition.
Tools & water used should be cleaned & free from impurities.
To ensure that hands are dry before putting them in the bag. After taking out plaster, always fold open end of bag to protect plaster from moisture.
Bags should be handled carefully to avoid tearing. Hooks are not recommended.

Basic Important Facts


The consumption of Gyptech Gypsum Plaster is directly related to the line & level of walls in the building, which is a variable factor. It also depends upon the basic wall base material i.e. Bricks or Blocks.
Based on field trials & experience, the consumption pattern of Gypsum plaster varies between 1.5 kg to 2 kg per square feet for 13mm thickness of plaster in right angle finish on the walls.
It is advisable to do a mock-up of an entire flat in your building to ascertain the actual consumption pattern of Gypsum Plaster.
