Difference Between POP And Wall Putty

Home » Construction Engineering » Difference Between POP And Wall Putty

Constructing a building involves several steps, from drawing plans to the final touches. The last and crucial step is the finishing, shaping the appearance and ensuring durability against external conditions.

Importance of Finishing

The finishing not only defines the structure’s look but also safeguards it from weather changes. Home renovation emphasizes a fantastic finish, achieved through components like Plaster of Paris (POP) and wall putty.

Exploring POP: Plaster of Paris

POP is a white powder made from Gypsum, used for wall coats, structural shaping, and casting. When moistened, it provides a swift and robust finish, made by heating gypsum to a high temperature.

Understanding Wall Putty

Wall putty, made from white cement and polymers, serves as paint putty. It enhances adhesiveness, prolongs substrate lifespan, and fortifies walls.

POP vs. Wall Putty

To make an informed choice, understanding the differences is crucial. Let’s delve into a detailed comparison.

Particulars Plaster of Paris (POP) Wall Putty
Best to be applied on On interior walls only Both interior and exterior walls
Binding property Very low binding property High binding property
Thickness 1 inch, covers undulations Max 3 mm thickness, ideal 1.5 mm
Strength Low strength Good tensile adhesion, compressive strength
Durability Less durable Highly durable
Average setting time 5-7 minutes 2 hours
Uses Wall finish, castings, decorative features Fills gaps, smoothes walls and ceiling
Finish Gives a leveled surface Cannot provide a perfect level surface like POP
Fire resistance Fire-resistant due to gypsum Less fire resistant
Skill for apply Very easy to apply Requires some skill
Application surface Cannot be applied on a moist surface Can be applied on a moist surface, no water curing needed

Applying Wall Putty

Surface Preparation:

  • Clean the walls with a hard metal brush.
  • Use emery paper to smoothen the surface of cement and sand.

Application:

  • Apply two coats of wall putty, allowing time to dry between coats.
  • Smoothen the surface with emery paper after the first coat.

Applying Plaster of Paris (POP)

Thickness and Application:

  • Apply a 5mm to 12 mm thick layer of POP on a wall where wall putty is not suitable.
  • POP is primarily used for interior parts due to its limited durability on exterior walls.

Types of POP:

  • Patra finish and Patti finish offer different rates and finishes.
  • POP plaster is crack, shrink, and fade-resistant.

Special Uses:

  • Ideal for creating ornaments and curvy designs on walls or ceilings.

Choosing Between POP and Wall Putty

Considering the advantages and disadvantages of both materials, wall putty offers more strength, binding, and versatility. POP, on the other hand, brings delicacy and sophistication to interior designs.
