When it comes to home renovation or construction, one of the most important decisions that homeowners and contractors need to make is the choice between using POP (plaster of Paris) or wall putty. These two materials are commonly used for finishing interior walls and ceilings, but there is often a debate about which one is better. In this article, we will delve into the details of both POP and wall putty, exploring their characteristics, advantages, and disadvantages, to help you make an informed decision about which material is best for your project. Let’s take a closer look at the differences between POP and wall putty and decide which one is the most suitable for your needs.
Which one is better to use POP or wall putty ?
When it comes to interior wall finishing, there are two commonly used materials – POP (Plaster of Paris) and wall putty. Both of these materials are used to achieve a smooth and uniform surface for painting or wallpapering. However, there are certain differences between the two, and choosing the right material can make a significant difference in the final outcome. As a civil engineer, I have encountered both materials and would like to discuss which one is better to use – POP or wall putty.
1) Material Composition:
POP is made from gypsum, a naturally occurring mineral, which is then processed and heated to produce a fine powder. On the other hand, wall putty is a white cement-based product with added additives like polymers, binders, and fillers to improve its adhesion, strength, and durability.
2) Purpose:
POP is primarily used for creating decorative elements on walls like cornices, mouldings, and ceiling designs. It is also used to cover cracks, repair damaged walls, and create a smooth base for painting. On the other hand, wall putty is used to level and smoothen the surface, fill in minor cracks, and create a suitable base for painting or wallpapering.
3) Application:
POP is a bit more challenging to work with as it sets quickly and needs to be applied in multiple layers. It requires skilled labor as it needs to be applied perfectly to achieve a smooth finish. In contrast, wall putty is easier to use, can be applied in a single layer, and can be sanded and polished to achieve a smooth surface.
4) Drying Time:
POP has a longer drying time compared to wall putty. It takes around 24 hours to dry completely, whereas wall putty only takes 4-6 hours to dry. The quick-drying time of wall putty makes it more convenient to use, especially when time is a constraint.
5) Strength and Durability:
POP is stronger and more durable than wall putty. It can withstand heavy loads, making it suitable for creating decorative elements. Wall putty is not as strong but can last for a long time if applied correctly. Moreover, it is resistant to water and prevents the growth of fungus and mildew.
6) Cost:
Wall putty is more expensive than POP as it consists of various additives that improve its properties. Additionally, the labor cost for applying POP is higher than wall putty as it requires more skill and effort.
In conclusion, both POP and wall putty have their own strengths and weaknesses. POP is best suited for decorative purposes and repairing damaged walls, while wall putty is ideal for achieving a smooth and even surface. Hence, it is important to consider the purpose and requirements before deciding which material to use. In my experience, a combination of both POP and wall putty is the best solution for achieving a flawless finish on interior walls.
POP vs wall putty-difference between pop and wall putty
POP (Plaster of Paris) and wall putty are both common materials used in the construction industry for finishing walls. While they may seem similar, there are some key differences between the two that make them suited for different purposes.
Composition:
POP is made from gypsum, a naturally occurring mineral, which is calcined and then ground into a fine powder. It is mixed with water to form a paste that can be applied on walls and ceilings. Wall putty, on the other hand, is a white cement-based powder that also needs to be mixed with water before application.
Application:
POP is usually applied in multiple coats, starting with a base coat followed by a finishing coat. The base coat is coarser and is used to create a strong base, while the finishing coat is smoother and gives a polished look to the wall. Wall putty, on the other hand, is applied in a single coat. It is used to fill in small cracks and imperfections on the wall surface before painting.
Strength and Durability:
Due to its composition, POP is much stronger and more durable than wall putty. It can withstand external factors like moisture, changing weather conditions, and even fire. Wall putty, on the other hand, is not as strong and cannot provide the same level of protection.
Finishing:
POP gives a smooth and polished finish to walls and ceilings. It can also be molded into decorative designs and patterns. However, wall putty gives a more matte finish and is mainly used as a base for paint.
Water Resistance:
As mentioned earlier, POP is highly water-resistant, making it suitable for use in damp areas such as bathrooms and kitchens. Wall putty, on the other hand, is not very water-resistant and should not be used in areas with high moisture content.
Cost:
In terms of cost, wall putty is more economical compared to POP. It is also easier to apply, reducing labor costs. However, due to its better durability, POP can provide long-term cost savings as it does not require frequent repairs and maintenance.
In conclusion, while both POP and wall putty are used for finishing walls, their composition, application, strength, durability, water resistance, and cost differ significantly. POP is more suitable for long-lasting, strong, and decorative finishes, while wall putty is ideal for temporary or budget-friendly options. It is essential to understand these differences and choose the right material based on the specific needs and requirements of your project.
Conclusion
In conclusion, when deciding between using POP or wall putty for your interior walls, it is important to consider various factors such as surface condition, application ease, durability, and cost. While POP may provide a smoother and more crack-resistant finish, wall putty is easier to apply and tends to be more affordable. Ultimately, the best option will depend on your specific needs and preferences. It is recommended to consult with a professional and conduct proper research before making a decision. Whichever option you choose, both POP and wall putty can enhance the appearance and longevity of your walls, ensuring a beautiful and long-lasting finish.
