For an external area of 7000 sq ft, you will need roughly 500 kg of JK putty if you are applying two coats and considering some buffer. But the actual JK Putty requirement can vary based on the following factors:

  • Application thickness: Thicker layers decrease coverage.

  • Surface condition: The use of putty is increased by extremely uneven or rough plaster.

  • Coats: For a high-end finish, some contractors use three coats.

  • Waste allowance: Always allocate an additional 10% to 15% for trimming and accidents.

For an external area of 7000 sq ft, you will need roughly 200 kg of JK putty if applying a single coat at 1mm thick. But the actual requirement will vary depending on your current wall condition and surface roughness. Let’s see how you can calculate the JK Putty requirement:

  • Firstly, you can multiply the height by the entire length of all external walls. 

  • After that, get the actual surface area that requires putty by subtracting the areas of all windows, doors, and other openings from the total wall area.

  • Generally, for a 1 mm thickness, JK Putty covers around 35 square feet per kilogram. However, on rougher surfaces, this may be less.

  • Now, use the formula below to know the approximate JK Putty requirement:

JK Putty Needed (kg) = (Total Wall Area (sq ft) / Coverage per kg)

Therefore, 7000/35 = 200 kg of JK Putty is needed for 7000 square feet of space, with 35 square feet per kilogram. It will weigh 400 kg for two putty layers. However, outdoor surfaces frequently require a little extra putty because of their texture, exposure to weather, and absorption. Adding a buffer will result in around 500 kg of JK Putty.

In the packaging, only details like JK wall putty consumption per sqm are often mentioned. I once read that the approximate coverage of JK Wall putty is 35 sqft/mm thickness/kg. Now to find the JK putty external requirement for 7000 sq.ft area, the calculation you will need to do is:

  • Divide the achievable coverage per kg

  • So 7000 sq ft/ 35 sq ft/kg = 200 kg

You will need 200 kg of JK wall putty for the external requirement of 7000 sq ft.
