Wall putty can be termed as the material that is used in skimming walls before painting. It is basically a smooth paste that serves to cover not only rough but also uneven areas. Upon its application, putty goes on filling in all the tiny cracks, holes, and imperfect areas. As a result, a smooth and an even base is created for the paint. Using wall putty improves the quality of the paint used, its adhesion is also prolonged and, on top of that, it is not going to crack or peel.
Moreover, wall putty also acts as a barrier against dust, moisture and slight damages. The majority of wall putties contain white cement, polymers and minerals as their constituent materials. These components impart strength, smoothness, and durability to the walls. Wall putty is advantageous concerning both interior and exterior walls. The interior wall gets an immaculate and polished look, while the exterior wall gains an additional layer of protection against rain, sunlight, and humidity.
A wall without putty is more likely to display uneven surfaces, marks or problems related to the old plaster. Painting directly on such walls can result in uneven color, peeling or early damage. Wall putty eliminates these issues and offers a robust and even surface for the paint. It also improves the aesthetics of the wall and extends the life of the paint.

Wall Putty Application Process: Step-by-Step Guide
To the get the right wall finish that is smooth and lasting for long, wall putty application is a must. Before anything else, here is a simple step-by-step guide on how to do it:
Step 1: Clean the Wall
Clean the wall surface nicely before applying putty. Dust, grease, old paint, and loose plaster need to be removed. A clean wall will provide a good bond for the putty and thus, prevent peeling or cracking.
Step 2: Mix the Putty
In case of powder putty, mix it with pure water to obtain a smooth paste. Gradually add water to avoid creating lumps. The desired consistency is that of cream and it can be easily spread on the wall. Ready-to-use putties do not require mixing and can be applied directly.
Step 3: Pre-Wet the Wall
Make the wall surface a bit wet before putting on the putty. This will make the putty grip better and also help it not to dry too fast.
Step 4: Apply the First Coat
With a putty knife or flat blade apply a very thin layer of putty and push it from bottom to top covering the whole area. The first coat will take care of filling the small cracks, holes, and uneven spots.
Step 5: Smooth and Dry
Give time for the first coat to dry completely. After it is dry use either a clean knife or sandpaper to smoothen and level the surface.
Step 6: Apply the Second Coat
Apply a second coat of putty thinner than the first one for a smoother finish. It is this coat that ensures the wall is completely even and is ready for primer or paint.
Step 7: Final Drying
Do not apply primer or paint until the wall has dried completely. The drying period is determined by the wall material, temperature, and humidity. A wall that is completely dry will provide better adhesion and more lasting results for the paint.
Putty or Primer First?
- First of all, the application order of putty and primer is still an issue to be resolved by the home decorators. The right sequence goes with: initially, putty, later, primer, and lastly, paint.
- By the application of putty, the wall is made smooth, and at the same time, cracks are filled. On the other hand, primer is applied over the putty to create a durable base for the paint. It guarantees the paint’s even spread, good adhesion, and long-lasting properties.
- A few top-grade putties might leave a surface almost similar to that of a primer, however, the application of primer after putty still offers a great benefit in terms of protection and aesthetics of the paint. Furthermore, if primer is skipped, surely the life of the paint would be lesser even if putty is used.
