Last month, I got my home painted, and my painter asked me to buy 40 kg of wall putty. At that time, I asked him how much area 1 kg of wall putty could cover. He explained that 1 kg of wall putty can cover approximately 20 to 25 square feet, when applied at a thickness of around 1.5 mm. Below, I have also mentioned the key factors that affect wall putty coverage.
What are the Factors that Affect Wall Putty Coverage?
The condition of the wall is one of the main factors. A smooth and properly plastered wall needs less putty. An old, rough, or damaged wall needs more putty to fill holes and uneven areas.
Some walls absorb more moisture from the putty. Porous walls, such as cement blocks and certain masonry surfaces, may need more putty. Using a suitable primer can help reduce absorption.
The number of coats also affects coverage. Usually, two thin coats are applied to get a smooth finish. If more coats are needed, more putty will be required.
The thickness of the putty layer directly affects the quantity used. A thick layer consumes more material. It is better to apply thin and even coats instead of one very thick layer.
Finally, the way putty is applied also matters. A skilled painter can apply it evenly and avoid unnecessary wastage. Proper tools, correct mixing, and good application techniques can help achieve better coverage.
So, hiring a professional painter can help you get a smooth and proper finish while also reducing unnecessary wall putty wastage. I hope you now have a clear idea of how much area covered by 1 kg wall putty and the factors that affect its coverage.
