When it comes to achieving a smooth and flawless finish on walls, wall putty plays a crucial role. Whether you’re preparing new walls or renovating old ones, choosing the best putty for interior walls can make a significant difference in durability, smoothness, and overall aesthetics. But with different types of wall putties available, how do you decide which one is best?
This guide provides an in-depth comparison of different types of wall putty, highlighting their benefits, applications, and which type delivers the best results for your walls.
Types of Wall Putty and Their Characteristics
Wall putty comes in various types, each designed for specific applications and benefits. Understanding these types will help in making an informed choice.
1. Cement-Based Wall Putty
Cement-based wall putty is widely used for both interior and exterior walls. It consists of white cement and added polymers that improve adhesion and durability.
Pros:
Strong bonding with the surface
Resistant to moisture
Can be applied on both interiors and exteriors
Provides a smooth finish
Cons:
Takes time to dry, depending on weather conditions
Requires proper surface preparation before application
Wonder Wall Putty is an example of cement-based wall putty where polymers are added to enhance performance. It is prepared by mixing water into the powder base, ensuring a strong and long-lasting finish.
2. Acrylic Wall Putty
Acrylic putty is a water-based product mainly used for interior walls. It offers a smooth finish and is easy to apply.
Pros:
Ready to use
Dries faster than cement-based putty
No water curing required
Cons:
Less durable than cement-based putty
Not suitable for high-moisture areas
3. Gypsum Wall Putty
Gypsum-based putty is made from calcium sulfate and is commonly used for interior applications.
Pros:
Provides a smoother and whiter finish
Ideal for interiors due to its lightweight nature
No water curing required
Cons:
Not suitable for damp or high-moisture areas
Less durable than cement-based putty
4. Polymer-Based Wall Putty
This type of putty includes synthetic resins and polymers to enhance adhesion and flexibility.
Pros:
High adhesion and flexibility
Reduces cracks and shrinkage
Suitable for interiors and exteriors
Cons:
Higher cost compared to other putties
Requires professional application for best results
Key Factors to Consider When Choosing the Best Putty for Interior Walls
To select the best putty for interior walls, consider the following factors:
1. Surface Compatibility
Ensure that the putty adheres well to the surface you are working on, whether it’s a concrete wall, plaster, or drywall.
2. Drying Time
While some putties dry quickly, others depend on weather conditions. Cement-based putties like Wonder Wall Putty take time to dry based on humidity and temperature.
3. Moisture Resistance
For areas exposed to moisture, opt for cement-based putty or Wonder Watershield Putty, which offers additional waterproofing benefits.
4. Ease of Application
Acrylic and polymer-based putties are easier to apply as they don’t require mixing, unlike cement-based options.
5. Primer Application
A common myth is that a primer should be applied after putty. However, no primer is required after putty application if the putty itself is of high quality.
6. Crack Filling Ability
While wall putty helps create a smooth surface, it does not fill holes or cracks. If there are significant damages, they should be filled with a separate crack filler before applying putty.
Application Process for the Best Results
For a flawless finish, follow these steps when applying wall putty:
Step 1: Surface Preparation
Clean the surface by removing dust, loose paint, and grease.
Ensure the wall is dry before applying putty.
Step 2: Mixing the Putty
If using cement-based putty like Wonder Wall Putty, mix it with water in the recommended ratio.
Stir the mixture well to achieve a smooth paste.
Step 3: First Coat Application
Use a putty knife to apply a thin, even layer.
Allow it to dry completely (typically 6-8 hours, depending on the weather).
Step 4: Second Coat Application
Apply a second coat for a smoother finish.
Let it dry completely before sanding.
Step 5: Sanding and Painting
Once fully dried, sand the surface with fine-grit sandpaper for a uniform finish.
Wipe off the dust before applying paint.
Which Wall Putty Delivers the Best Results?
The choice depends on your specific needs:
For high durability and moisture resistance, cement-based putty like Wonder Wall Putty is the best option.
For quick interior applications, acrylic putty is ideal.
For ultra-smooth finishes, gypsum-based putty works well but should be used in dry areas.
For flexibility and crack resistance, polymer-based putty is the best choice.
If waterproofing is a concern, Wonder Watershield Putty is a specialized solution designed to protect walls from moisture damage.
Choosing the right wall putty can make a significant difference in the finish and durability of your walls. While different types serve different purposes, cement-based putty like Wonder Wall Putty remains a top choice for its strength and versatility.
Remember, putty does not dry quickly—it depends on weather conditions, and no water curing is required for high-quality putties. Additionally, primer application after putty is unnecessary if the putty provides a smooth and uniform base.
By selecting the best putty for interior walls, you can ensure a long-lasting and aesthetically pleasing finish for your home or workspace.
