Putty consumption per 1 m2
Professionals are aware that the putty consumption per 1 m2 depends on the type of composition, as well as the surface on which it is applied. Masters who do not have skills in construction, but who decide to make repairs with their own hands, should familiarize themselves with the rules for calculating the required amount of material. If this is not done, then the product may end in the middle of work, which will lead to a trip to the store, preparation of the composition and an attempt to dock the product already applied with a new layer.

The product is classified according to the sequence of application:
- Starting lineup. Any instruction indicates that this tool is used first after priming the surface. The composition smoothes the surface and masks defects.
- The finish tool. It is applied after using the starting composition. Finally levels the building foundation. After applying the finish and priming, the finish is done.
- Universal product. It is used both as a starting and finishing tool.
Types of product in readiness for use:
- Ready composition. It is a paste-like product that does not need preparation. Used immediately after opening the bucket. Ready putty is easy to use. With its application, even non-professionals will have no problems.
- Dry mix. It is a powder for dilution with water. To prepare the product, you need a construction mixer for whipping. Advantage - low price.
Putties are also distinguished by the main component of the composition. Funds are classified into gypsum, cement and polymer putties. The first composition is intended for use in dry rooms, and the rest in rooms with high humidity. The tool is classified and depending on the place of work. Allocate a composition for external decoration and for indoor use. The calculation of putty per square meter depends on what kind of tool will be used to align the walls.
What does the flow rate depend on?
As a rule, the packaging indicates how much money is required per 1 m2. However, manufacturers do not take into account all factors when they provide such data. Therefore, it is recommended to know how to calculate the consumption of putty yourself.
The cost of funds depends on the following factors:
- The degree of preparation of the building foundation. If the surface has been primed, then the material consumption will be less. The fact that the primer reduces the cost of the composition.
- The presence of defects on a building basis. If there are cracks, dents, etc. on the surface, then the product will need more than when applying the product on a flat wall or ceiling.
- Types of building base. If the puttying of the walls is made of wood, then the consumption of material will be one, and if it is made of metal, then another.
- Stage of work. The starting agent is applied with a layer of 5 mm, and the finishing agent is 1 mm. Therefore, the first remedy will need more than the second.
- Professionalism of the master. A beginner in the construction business will need more material than a professional. The specialist accurately determines which layer is applied to the surface. The beginner does not have such a skill, so usually he makes the layer a little thicker than what the working rules require.
Calculation of putty consumption for different types of surface
Putty consumption rate per 1 m2 depends on the surface on which the product is applied.
Drywall
This building foundation is even in itself, but you still cannot do without using this material. The tool is applied to the joining seams (as in the photo), the corners and caps of the screws. Then the surface is treated with the finishing composition. Pre-drywall is recommended to be primed. This will reduce putty consumption. The calculation of the amount of composition depends on the type of product:
- Cement based product. Putty consumption per 1 m2 is 1.2 kg.
- A plaster based product. The required amount is calculated by the formula: 1 kg per 1 m2.
- The polymer composition. Such a tool will need 0.6 per 1 m2.
Plaster
When the putty consumption per 1 m2 is calculated (an online calculator can be found on the appropriate site) for applying the composition to the plaster, it should be borne in mind that work should only be carried out under the conditions of humidity and temperature that are indicated on the package. The condition of the building base is also taken into account. If the surface does not have significant defects, then the consumption of the composition is calculated by the formula - 1.5 kg per 1 m2. A defective building foundation will require more funds. For example, if putty is applied with a layer 5 mm thick, then the consumption will be 5.5 kg per 1 m2.
Other construction grounds
Putty consumption per 1 m2 for concrete is calculated according to the formula indicated on the package. If the composition is needed for a wooden surface, it is taken into account that the layer of the product does not exceed 2 mm, otherwise the mortar weighted the building base. Consequently, the consumption will be less than for any other bases by about 1.5 times.
Calculation of the consumption of different types of composition
When calculating the consumption of putty, it is also taken into account which composition is used for work.
Starting tool
Starting putty - consumption per 1 m2 1 kg. This is the standard formula for such a tool. However, such a calculation is taken if the layer thickness is 1 mm. If it is required not only to smooth the surface, but also to hide defects, then the putty is applied in several layers. The result is a base even in 5 or 10 mm. Then the expense of the product increases and is 5 kg and 10 kg per 1 m2, respectively.
Finish lineup
It is applied on a surface 1 mm thick. The consumption of funds in this case is 1 kg per 1 m2. If the surface preparation was not performed correctly and the base needs more careful leveling, then the layer thickness increases to 2 mm. The calculation of the consumption will then be 2 kg per 1 m2.
Universal product
The calculation of a universal tool is based on the fact that the composition will be used for rough and finish work. For a flat surface, it is enough to apply 3 mm of putty. Consumption, respectively, will be 3 kg per 1 m2. If the construction base is defective, then applying a material of 6 mm will be required. Consumption will then be 6 kg per 1 m2.
The video in this article clearly demonstrated how to calculate the consumption of putty.
When the putty consumption per 1 m2 is calculated, another 100 g is added to the result. This is an error that is taken into account when buying funds for unforeseen situations.
