Introduction
In construction, surface finishing is just as important as structural strength. Plastering and pointing are two commonly confused surface finishing techniques. They serve different purposes but are often used in conjunction with each other.
Understanding the difference between plastering and pointing in construction can help you make well-informed choices, whether you’re building from scratch or renovating.
That’s exactly what we’ll explore in this blog.
What is Plastering?
Plastering is a method of applying a coat of paste made from cement, lime, or gypsum on the internal and external surfaces of walls and ceilings. Its primary purpose is to provide a smooth, protective, and sometimes decorative finish. It also acts as a protective layer against moisture and dust and forms a strong base for paint, tiles, or wallpaper.
Different Types of Plastering:-
Plastering comes in several types, each suited for specific needs.
Cement Plaster:
The most common are cement plaster-a tough mix of cement, sand, and water ideal for both interiors and exteriors.
Gypsum Plaster:
This plaster of Paris creates smooth, quick-setting finishes perfect for interior walls.
Lime Plaster:
It is traditional and breathable, great for older or damp-prone buildings.
Mud or Clay Plaster:
It uses natural earth materials for eco-friendly homes.
Stucco Plaster:
For decorative appeal, it adds texture to walls.
What is Pointing?
Different Types of Pointing:-
Common types pointing include
Flush Pointing:
Mortar is finished level with the surface, offering a smooth, durable finish.
Recessed Pointing:
Mortar is pressed back from the brick face, creating a neat, shadowed line.
Beaded Pointing:
A raised, rounded bead of mortar is formed for a decorative look.
Weathered or Struck Pointing:
Mortar is sloped outward to shed rainwater effectively.
Tuck Pointing:
A thin, contrasting line is inserted in the joint to give a neat, elegant appearance.
V-grooved:
The mortar joint is formed with a V-shaped groove for added style.
Keyed Pointing:
Mortar is indented or shaped to improve bonding and add visual detail.
Comparative Analysis of Plastering and Pointing
To better understand the roles of both methods, here is a comparative analysis of plastering and pointing:
| Plastering | Pointing | |
|---|---|---|
| Purpose | Surface finishing and protection | Protects joints from water entry and visual appeal |
| Application Area | Full surface of walls and ceilings | Only between bricks or stones |
| Material Used | Cement, sand, lime, gypsum | Cement-lime mortar, sand |
| Labour & Time | Labour-intensive and time-consuming | Quicker to apply |
| Tools and Equipment Used | Trowels, plastering floats, hawk board, spirit level, mortar pans | Pointing trowel, joint raker, wire brush, chisel and hammer |
| Appearance/Finish | Uniform, smooth, or textured | Visible and decorative joint lines |
| Durability | High with proper curing | Depends on mortar quality |
| Cost | Slightly higher | More economical |
Advantages and Disadvantages of Plastering:-
| Advantages | Disadvantages |
|---|---|
| Provides a smooth and polished surface | More time-consuming compared to other finishes |
| Enhances aesthetic appeal of walls | Requires skilled labour for proper application |
| Acts as a strong base for paint and decorative finishes | Improper curing may lead to cracks over time |
| Protects walls from moisture, dust, and external damage | Generally more expensive than pointing |
Advantages and Disadvantages of Pointing:-
| Advantages | Disadvantages |
|---|---|
| Strengthens masonry joints and improves structural integrity | Less suitable for smooth or finished surfaces |
| Helps prevent water seepage through brick or stone joints | May require periodic maintenance, especially in harsh climates |
| Enhances the visual appeal of exposed brick or stone walls | Labour-intensive for detailed or older structures |
| Cost-effective and quicker to apply | Not ideal for damaged or weakened walls |
Step-by-Step Application Process for Plastering and Pointing
Both methods have unique techniques. Here is a simplified step-by-step application process.
Plastering:-
- Clean the wall surface
- Apply bonding agent if required
- Mix plaster in the correct ratio (usually cement: sand = 1:4 or 1:6)
- Apply a base coat
- Level with a float or straight edge
- Cure for 7 days
- Finish with a second coat and smoothen
Pointing:-
- Remove loose, old mortar from joints using a joint raker
- Clean joints with a brush or jet spray
- Prepare pointing mortar
- Fill joints with pointing mortar using pointing tools
- Shape and finish joints as per type
How Max Cement Ensures Quality in Plastering and Pointing?

Our range of high-grade OPC and PPC cement is trusted by builders across India for its durability, workability, and superior binding strength. Whether you’re building your dream home, working on high-rises, or home interiors, Max Cement offers unmatched long-term value.
FAQs
Which cement is best for plastering and pointing?
For plastering:
The best cement for plastering depends on the requirements. However, the two most commonly used types are Ordinary Portland Cement (OPC) and Portland Pozzolana Cement (PPC). OPC is best for its strength and quick setting, making it suitable for general construction. PPC, on the other hand, is preferred for its superior workability, enhanced durability, and reduced tendency to crack, making it an excellent choice for both interior and exterior plastering, especially in humid or coastal regions. Extra source for details.
For pointing:
The best cement for pointing depends largely on the type of masonry and whether the building is modern or historic. For modern brickwork, use OPC (Ordinary Portland Cement) or PPC (Portland Pozzolana Cement) for pointing-mix 1 part cement to 2-4 parts sand, sometimes adding lime for workability. For historic or soft masonry, use lime mortar (fat or hydraulic lime, 1:2 or 1:3 with sand) to protect older bricks and allow walls to breathe. Use cement for strength and lime for breathability in older walls.
When to use plastering vs. pointing?
Use plastering for internal walls and ceilings. Pointing is ideal for exposed brickwork or stone structures. Remember, the decision depends on the purpose of the wall, environmental conditions, and finish preferences.
Can plastering and pointing be done together?
Yes. However, doing both on the same surface can lead to inconsistencies unless expertly planned.
Is pointing good for waterproofing?
Yes, pointing, when done correctly, can contribute to waterproofing (source from a research on water penetration of brick masonry), but it is not a complete solution, especially in areas with high moisture.
