Plaster Of Paris
Plaster Of Paris
Dudhi Plaster of Paris is the highest grade quality plaster which will support your ideas about gorgeous interiors in to a reality. It consists of gypsum hemihydrates specially treated high purity gypsum and additives to achieve strong, durable plaster and with more coverage. This plaster is most suitable for application of internal plastering system as punning of walls and ceilings, all decorative works like cornices, roses, moldings, arches apart from in-situ false ceiling systems.
Superior whiteness of this plaster assures aesthetics of interiors and Micronics Grinding Method (MGM) provide extra fineness which results into smooth and fine carvings as desired.
Dudhi Gypsum guarantees consistency in quality in terms of setting period, coverage, free from impurities, weight, etc which generally occurred in batch-after- batch process.

Features & Benefits
- Eliminates two-step process of Sand Cement Plaster and POP punning
- Doesn’t require water curing
- No shrinkage cracks
- Non-combustible (when tested in accordance with BS: 476: part 4:1970), therefore a good form of
thermal protection to the building structure. - Use of light weight aggregates in the plaster mix help to improve Low thermal conductivity (0.25
W/m-K) as compared to Sand Cement Plaster (0.72 W/m-K) ** keeps room cooler in summer and
warmer in winter; saving in energy cost - The water absorption as per DIN EN 520 is less < 10%
- Excellent Capillary
- Water absorption coefficient test method —- BS EN 1015-18.

Storage & Handling
Dudhi Gypsum (Brick Solution) (Moisture Resistant) is supplied in 4OKg bags. The dimensions of the bag ensure that a well-filled appearance is presented when filled and the bags can be stacked on a pallet in a stable and well-stacked array. Bags should be stored dry, as absorption of water shortens the setting time, causes set lumps to (*) form in the bags and may reduce the strength of the set plasterwork. No hooks or any sharp tools should be used to carry bags from one location to another.
Application Areas
Dudhi Gypsum (Brick Solution) one coat plaster can be applied on most internal surfaces like Bricks, Blocks & RCC (Concrete) surfaces.
Background Preparation
Surfaces should be completely clean, reasonably dry, protected from the direct exposure from weather and suitable for the chosen specification. In addition, before plastering concrete backgrounds, ensure that any mould oil or Concrete Curing Agent (other agents) present are removed from the surface. No-fines concrete does not require wetting prior to plastering. Plaster should not be applied onto a ‘green’ background or when any free water is visible. Clean water should be applied 5-10 minutes before plaster application to control the suction. In-situ or pre-cast concrete which are exceptionally smooth or having low suction will require pre-treatment with Dudhi Plaster Bond bonding agent.
Mixing
Dudhi Gypsum (Brick Solution) (Moisture Resistant) is pre-mixed with aggregate and only clean water needs to be added to prepare it for use. Mixing should be carried out in a clean tray or bucket. Excessive mechanical mixing should be avoided. Tools and water used in mixing must be clean. Contamination from previous mixes can shorten the setting time and in turn reduce the strength of the plaster when set. Water to plaster ratio (1 part of water: 1.5 part of plaster by weight) should be maintained to have good cohesive workable mix. Prepare plaster mix as much as required depending upon the immediate scope of work. Once the mix has begun to set, additional water is not to be added, as performance properties of plaster will get altered, thus affecting workability, cohesiveness, adhesion properties and strength.
Application
Dudhi Gypsum (Brick Solution) (Moisture Resistant) should be applied with firm pressure, built out to the required thickness, and ruled to an even surface and left as an undercoat to form a key for finish coat. A thin plaster mix is made and applied as a finish coat to provide smooth surface. It can be applied to an average thickness range of 6-15 mm on walls in one coat and up to 10 mm on ceilings. For thickness above this range, material needs to be applied in two coats. The thickness should not increase to more than 30 mm (average thickness) on walls and 20 mm (average thickness) on ceiling. After complete drying for usually 72 hrs (depends upon thickness and weather conditions) the plain smooth leveled surface is ready for painting.
Precautions
- Dissimilar expansion and contraction of RCC and brick / stone masonry could cause stresses and at times separation. To reduce the separation cracks, use of 145 GSM glass fiber mesh (at the junction) is recommended.
- Itis not suitable for use in long continuously damp or severely humid conditions
- If Gypsum Plaster is to be applied on RCC surfaces with the thickness of the application being more than 15 mm then It is to be applied only when moisture is very low and the temperature is more than 10 degrees Celcius because RCC construction has almost negligible porosity as compared to NON-RCC SURFACES. Hence it cannot absorb water.
External Plaster Work Care
In case Dudhi Gypsum (Brick Solution) is applied on internal walls but the exterior cement plaster work of the same wall is pending then Cement Plaster work must be completed prior to painting of the internal walls. Any seepage of moisture during curing from outside will from escape surface of the Gypsum plaster. Please note that the escaping water from Dudhi Gypsum (Brick Solution) may leave some green spots on the surface which can be easily removed with the help of sand paper and then Paint work of the internal walls should be done.
It is not suitable for use in long continuously damp surfaces. For application make the substrate dry and then application to be made.
The information herein should not be read in isolation as it is meant only as guidance for the user, who should always ensure that they are fully conversant with the products and systems being used and their subsequent installation prior to the commencement of work.
