Nearly everyone has experienced a renovation project at least once, especially when it comes to interior wall finishing. One of the most common and straightforward techniques to pre-treat walls before applying paint or wallpaper is by using wall putty. Whether you decide to tackle the project yourself or hire a professional construction team, it is essential from the outset to understand the materials required and the overall cost.
The amount of wall putty needed for finishing interior or exterior surfaces primarily depends on the type of putty you use – such as gypsum, cement-based, or polymer variants. Other important factors include the total surface area, the presence of openings like doors and windows, any surface imperfections, as well as the method of application and the thickness of the putty layer. By using our online wall putty consumption calculator, you can accurately determine the required amount of material per square meter, a crucial factor for planning your renovation project.
For the most precise cost estimation and material planning, utilize our construction calculator to calculate the wall putty consumption per square meter. Even with average estimates, our tool efficiently computes the necessary quantity by taking all relevant parameters into account.
First, measure the total length of the walls in the room where you intend to apply the finishing putty over the plaster. For example, if a room has four walls measuring 5 m, 5 m, 3 m, and 3 m, and you subtract an opening such as a 2.2 m door, then the effective wall length to input in the calculator would be 13.8 m.
Next, determine the wall height, which is simply the distance from the floor to the ceiling without any hidden complexities.
Then, specify the average thickness of the putty layer along with the number of layers to be applied. Typically, when preparing a surface for wallpaper, two layers are sufficient if the underlying plaster is applied correctly. However, for painting, three to five layers might be needed to ensure a quality finish. For instance, gypsum-based putty is generally applied in layers of 1-2 mm, polymer-based putty in layers of 0.2-2 mm, while cement putties might be applied up to 3 mm thick. Always follow the manufacturer’s recommendations, as they provide the optimal layer thickness and consumption rate per square meter.
Keep in mind that the ideal application thickness is specified by the manufacturer, so be sure to adhere to these guidelines in your calculation.
Applying wall putty results in a robust, smooth surface free of irregularities and defects, providing an excellent base for long-lasting wallpaper or paint. You can purchase putty either as a dry mix to be diluted with water or as a ready-to-use putty mass. Typically, the consumption rate is between 1 and 1.5 kg per square meter for a 1 mm layer, depending on the mix.
Additionally, our calculator allows you to choose from popular putty brands such as Vetonit or Knauf, each well-known for their specific usage guidelines. For example, Knauf putty is highly praised for its performance on drywall and similar surfaces.
Finally, enter the price per bag – reflecting the current market cost for one unit of the material.
Once you have entered all the necessary data into our online wall putty consumption calculator, click the "calculate" button. Instantly, you will receive all the essential details, which you can print out for reference during your purchase. This efficient tool streamlines the process, ensuring you know exactly how much material is needed per square meter of wall.
