Plaster of Paris (POP) DIMENSIONS
Plaster of Paris dimensions are really important, for people who work on construction sites, like contractors and project managers. They need to know the size and thickness of Plaster of Paris. This way they can avoid wasting Plaster of Paris and keep their costs under control.

Thickness of Application:
For Walls: When you put it on cement walls to make them flat the first layer, which is the base coat is usually 6 mm to 10 mm thick. This is the coat of the walls. After that a fine second layer of 2 mm to 3 mm is put on the walls to give a smooth finish that looks like glass. The total thickness of the walls can be between 12 mm to 15 mm.
For Ceilings: For ceiling designs and decorative moldings on the ceilings the thickness can be between 15 mm to 25 mm. This depends on how complex the design of the ceilingss.
Fineness (Mesh Size): The fineness of the powder, which is also called the mesh size is very important for the finish of Plaster of Paris or POP. The final finish of POP depends entirely on how fine the powder of POP’s. Shashwat POP is filtered through 150 to 200 mesh sieves. This makes the powder of POP as smooth as talcum powder.

Plaster of Paris (POP) Application
Applying POP is a very sensitive job. If you do not mix or apply it in the correct ratio, even expensive materials can get wasted. According to Shashwat experts, here is the scientific way to apply POP:
Surface Preparation:
Clean the wall or ceiling surface thoroughly with a brush. Remove all dust, oil, grease, old paint, or loose concrete.
If the surface is very dry, spray some water to make it damp. A very dry surface will quickly suck the water out of the POP paste, making the POP weak.
Scientific Mixing:
Take a clean bucket made of plastic. Remember to do this: pour water into the bucket first and then slowly add the POP powder. The usual mix is one part water to one and a half parts POP.
Let the Plaster of Paris powder sit in the water for a couple of minutes so Plaster of Paris can absorb the water properly. Then we mix Plaster of Paris with a wooden stick or an electric mixer to make a smooth paste with no lumps in the Plaster of Paris.
Application Process:
Use a trowel and a float to apply the paste to the wall or ceiling. Apply it from bottom to top with even pressure.
Let the first layer set slightly, and then apply the final thin finishing coat.
Curing & Drying:
The best thing about Plaster of Paris is that it does not need us to sprinkle water on it for days like we do with cement plaster. We just let Plaster of Paris dry naturally in the air for 24 to 72 hours. Once Plaster of Paris is dry it is fully ready for us to paint it.
Advantages of Shashwat POP
Why do top builders and interior designers choose Shashwat POP when there are so many local brands in the market? Let us look at the key benefits:
King of Whiteness: Shashwat POP comes from the finest gypsum mines in Rajasthan. These mines have the purest gypsum in the world. The natural whiteness is so high that you do not need to apply double coats of primer before painting. This directly saves up to 20% on your painting costs.
Butter-Smooth Spreading: The Shashwat POP spreads easily on walls because it has extra-fine particles and a special formula. This makes it easier for workers. They can work faster up to thirty percent faster.
Saves Time for RERA Deadlines: Cement plaster needs 15 to 20 days to dry and cure. With Shashwat POP, you can start painting within 3 days of application. This helps builders finish their projects on time and avoid heavy penalties.
Crack-Free and Moisture-Resistant: Shashwat POP can handle changes in temperature without getting any cracks. It is also very good, at keeping moisture out which helps protect the walls from getting damaged quickly.
Uses of Plaster of Paris (POP)
POP is not just a building material. It is a perfect blend of art, modern architecture, and technical strength. Let us explore its many different uses.
POP use in Construction Work
When workers build walls and ceilings with concrete, they often leave behind small holes, uneven areas, and rough joints. POP for Walls is the best material to fill these gaps and make the walls as smooth as glass. It is perfect for making the corners of windows and doors sharp and straight. When light falls on these smooth walls, it does not show any shadows or uneven spots, making your paint look incredibly beautiful.
POP in Medical Use
The use of POP is not limited to luxury homes. It has helped millions of people in medicine. When someone breaks a bone (fracture), doctors use a hard white plaster cast to keep the broken bone in the correct position. This plaster is actually highly pure POP. It is wrapped wet over bandages. It dries within minutes, becomes extremely strong, and helps the bone heal properly.
POP in Interior design
For interior designers, POP is like magic clay. Because it is highly flexible, they use it to make carved arches over main doors, beautiful Greek-style round pillars, and elegant carved borders called cornices along the edges of ceilings. It can turn a simple flat into a royal palace or a five-star hotel.
False Ceilings
Today, almost every modern home or corporate office has a false ceiling. False Ceiling POP is the most popular choice to build a secondary ceiling and install hidden LED lights (cove lights) inside it.
It looks highly beautiful and also hides ugly electrical wires, internet cables, fire sprinklers, and air conditioning ducts.
Wall Mouldings
Painting walls flat is an old trend. Today, people love to make beautiful frame-like borders on their walls, which are called wall mouldings. With Shashwat POP, you can create fine, classic, and elegant wall frames. These designs give your home a classic European or Victorian look. It adds depth to your walls and makes even simple rooms look very expensive.
Texture Designs on walls
If you want to make one main wall (feature wall) in your living room or bedroom stand out, you can create beautiful raised textures using POP. Workers use special tools, combs, or rollers on wet POP to make wave-like, wood-like, or geometric patterns. For such artistic work, designers always use Decorative POP, which is specially made to hold fine designs for a long time without cracking.
Repair Work
In old buildings, it is common to see cracks, holes from nails, or peeling plaster due to old dampness. POP is the best material to repair these issues. It dries very fast and bonds so well with the old wall that you cannot even tell where the repair was made.
Comparative Study and Practical Guide
When you choose materials for your home, you have several choices. Let us look at some key comparisons to help you make a smart and budget-friendly decision.
POP vs Traditional Cement Plaster
Traditionally, people used sand and cement plaster for their homes. But why does modern architecture prefer applying POP over it? Let us understand this through a simple comparison table:
Which is better, pop or putty?
This is a question that every home builder asks. Let us understand the difference and find out which one is right for you:
Wall Putty: Putty is made of white cement, polymers, and minerals. It is applied to walls in very thin layers (1 to 2 mm). It is used to fill very minor roughness on the wall and help the paint stick better. It also offers good protection against light moisture.
POP: You can apply POP in thick layers from 5 mm to 25 mm. If your walls are very uneven or have big holes from concrete casting, putty will not work. You must use POP to make them straight and flat. Also, you can only make ceiling designs with POP, not with putty.
Conclusion: If your walls are already very flat and you just need a smooth base for paint, go for wall putty. But if you need to fix uneven walls, make sharp corners, build up thickness, or make beautiful ceiling designs, then POP is your only and best choice.
