Gypsum Plaster is gypsum based plaster suitable for application on most internal backgrounds including brick, block and concrete. It consists of gypsum hemihydrates, formulated with special additives to enhance working and setting characteristics. It contains light weight exfoliated aggregates to improve plaster’s workability, coverage, application and post usage behavior. It dries to provide a white, smooth matt finish ready for painting.
It has high insulating properties
Improves indoor environment air quality
Dry construction (Water free), hence it is water efficient
Enhanced light reflectance, imparts true color tone and gloss for paint because of its surface perfection
Directly applied, single coat application
Free of shrinkage cracks
Imparts high coverage of 1.8 m2/25 kg at 13 mm thickness
Achieves desired smooth finish
Compatible with all types of paints
Available in 25 kg packaging HDPE bags
Dry bulk density: 650-770 Kg/m3
Wet bulk density: 1.50-1.60 Gm/m3
Initial setting time: 15 - 20 minutes
Final setting time: 20 - 25 minutes
Approximate coverage: 1.8 m² / 25 kg in 13 mm thick coat
Application & Surface Preparation
The background to be plastered should be thoroughly brushed with broom to be free of all loose particles and dust.
Wash and clean traces of mould oil.
It is recommended to use a high performance bonding agent on RCC concrete surfaces to eliminate hacking.
In case of hacking, provide 25 hacks, 10-15 mm deep per sq ft.
It is recommended to wet the surface before application so as to achieve more spread and higher coverage.
Mix One Coat Gypsum Plaster with water (not vice versa), use a mixing rod for thorough mixing and avoid lumps and unmixed residues.
Water to plaster ratio (1 part of water: 2 parts of plaster) should be maintained as to have good cohesive workable mix.
Mix One Coat Gypsum Plaster as much as required depending upon the immediate scope of work, partially used material to be kept well secured in dry place.
Once the mix has begun to set, additional water should not be added, as performance properties of One Coat Gypsum Plaster will get altered, thus affecting workability, cohesiveness, adhesion and strength.
Avoid using a wet brush on the finished surface, as that would leave permanent brush marks and thus spoil the surface.
A single coat should not exceed 13 mm in thickness, if at all thickness required is more than 13 mm, plaster is to be applied in multiple coats.
After complete drying (which takes usually 72 hours depending upon the thickness and weather conditions), the plain smooth leveled surface is ready for painting.
