All about putty consumption for 1 m2 + calculator

It’s imperative for anyone painting or renovating to understand putty consumption. It can save you time, money, and effort to know how much putty you’ll need, whether you’re a professional painter or a do-it-yourself enthusiast. Putty is used to smooth surfaces, fill in cracks, and get walls ready for a perfect coat of paint. An application process that runs smoothly and a polished outcome are guaranteed when the proper amount is calculated.

Putty consumption per square meter depends on a number of variables, such as the kind of putty, the state of the surface, and the required thickness. For instance, more putty will be needed to achieve a smooth finish on an uneven or rough wall than on a surface that is comparatively smooth. Additionally, the application techniques and coverage rates of various putties—like acrylic or oil-based—vary.

What the consumption depends on

1. The condition of the walls. The larger the depth of cracks, more protrusions, irregularities and roughnesses, the greater the thickness of the putty, and therefore the consumption.
2. Subsequent finish. The thickness of the layer depends on what the base will later be covered – paint, whitewash or wallpaper.
3. The experience of the master. Beginners consumed more material.
4. Place of work. When decorating the outer walls and surfaces in wet rooms, a facade putty on a cement basis is used, which requires more than a plaster. For interior decoration, dry gypsum mixtures diluted with water, and ready -made compositions are suitable. Ready for 1m2 there are less than dry, but they cost more.
5. Stage of putty. The primary elimination of cracks and recesses is carried out by a starting putty, which has the largest consumption. A universal mixture for even walls can replace the starting and finish. Universal requires a little less than the starting. The finish is used to create a smooth surface for painting or gluing wallpaper, so a very small amount is consumed.
6. Surface type. On the walls of the putty, more than on the ceiling.
7. The composition of the putty. Cement -based mixtures need to be bought more than alkyd. And gypsum putty is needed twice as much adhesive.

Starting putty consumption

Is a decorative link that is in between. It goes on plaster before the finishing mix. has a rough fraction most of the time because it contains lime and gypsum, so it will be consumed in large quantities. The mixture is placed into 25 and 30 kg paper bags. To prepare a dry component weighing 1000 g, mix 400 g of cold water into it until it becomes pasty.

Starting putty requires, on average, 1000–1400 g per 1 m2 when applied in 1 centimeter on the wall.

It has been demonstrated through experimentation that 10–20 m³ of primary putty surfaces with only minor flaws can be covered by a single, 30 kg package. The bag will cover 4–7 square meters if the walls are excessively uneven and damaged and the putty layer is at least 0.5 cm thick.

Read the instructions carefully before applying putty to determine the maximum thickness that can be applied at one time. Typically, the indicator shouldn’t be larger than 0.5–1 cm. The putty is likely to shower if you apply a larger layer at a time. As an illustration:

• Polimin Shg-10. Can be applied with a layer of 0.3-1 cm, while the consumption per 1 m2 for each millimeter of the layer is 1050 g.
• Satyn PW-01. The maximum layer width is 0.8 cm. 1 m. sq. It leaves 1300 g.
• Ceresit CT 29 . One passage should not be 0.2-2 cm thicker, but 1 m. sq. consumed for 1800 g for each mm layer.
• Knauf HP Start . Can be used as plaster and as a primer, based on lime and gypsum. The layer can be applied 1-3 cm thick. With a minimum indicator of one 30-kilogram is enough for processing 4 m. sq. walls. The processed surface is obtained quite granular with grain size up to 1.3 mm. Drying time – 7 days.

Name	Calculated thickness (in mm)	The required number of composition per 1 m2
Knauf HP Start	from 10 to 30	7.5 kg with a layer 10 mm
Ceresit CT 29	from 2 to 20	1.8 kg with a layer of 1 mm
Polimin Shg-11	from 3 to 10	1.05 kg with a layer of 1 mm
Satyn PW-01	up to 8	1.3 kg with a layer of 1 mm

The consumption of universal putty

On the prepared surface, a universal mixture (start-finish) is applied. The finished putty cannot be used after that. It comes in a 20 kg paper package, which is sufficient to process walls that are 15 to 20 square meters. You may occasionally come across 25 kg bags. Examples of content that is universal include:

• Stabill PSZ-11. With a layer of 0.1 cm per 1 kV. m consumed 1200 g. The maximum permissible coating thickness is 3 cm, but you need to apply in stages 0.7 cm approaches. Putty putty in packages of 20 kg.
• Sniezka Acryl-Putz . 1,500 g/m2 goes to the millimeter layer.
• Knauf multi-finish universal. Popular gypsum mixture, which is consumed 1200 g per m. sq. when applying a layer of 1 mm. The manufacturer claims that packaging weighing 25 kg is enough for processing 20 m .sq. grounds.

The consumption of the finish putty

The finish mixture, which you must use prior to painting, aids in creating perfectly even walls and ceilings. It is produced either as a finished composition or as a powder, and it is packed in buckets that weigh 8, 17, or 25 kg, though smaller volumes and capacities are also available.

The powder must be diluted 1:1.05 with water in order to create a putty of dry material.

Although more costly, ready-made mixes are consumed more frequently. Some finish putty examples are:

• Vetonit lr +. Dry mixture based on special polymer compositions. Sets in bags of 25 kg. On a millimeter layer of 1 kV. m. Vetonite consumption – 1200 g. The thickness of one pass should not exceed 1-5 mm.
• KNAUF SATENGIPS finish . Packages in packages of 25 kg. The minimum layer is 0.2 mm, and the maximum is 5 mm. Per square of 0.1 cm thick, 1000 g of the composition.
• Volma. It is used to process plastered walls made of concrete, slag concrete, partitions from grooves, for aligning the facade. On external and internal walls, the required amount of composition is different. On average, 1 m2 takes 1200 g.
• Knauf Uniflot . It is used for internal work, when setting joints between drywall sheets. Does not crack, does not give shrinkage, is harmless to a person. Applied with a layer of 1-5 m. It goes to the ceiling up to 300 g/m2, for partitions – from 500 g/m2. Sold in bags of 5, 25 kg.

The consumption of ready -made mixtures

The putty surface, once completed, is utilized for wall smoothing, ceiling alignment, and small carpentry flaws. Plasticizers and vinyl compounds are included in the composition to enhance the surface quality after application.

The putty is instantly ready to use, dries quickly, and does not crack.

• Shitrok. Pretty economical material. On a layer of 1 mm and an area of ​​1 m. sq. You will need 500 g of shitrok. For masters, the composition is popular due to the short period of drying, the lack of asbestos, the simplicity of use and the lack of cracks after drying out. Such characteristics are achieved due to vinyl components that increase elasticity. Suitable for finishing internal work and to fill the joints of the Gipro.
• Fugenfüller Knauf. Gypsum putty, which can be applied with a continuous layer. 1m2 is 800 g. If the fugenfüller is used during the installation of grooves, then the putty consumption increases to 1,500 g/m2.
• Pufas, Ceresit. Consumed on average of 1500-1700 g/m2;
• Vetonite putty when applying with a layer of 1 mm is consumed for 1200 g/m. sq.

It should be noted that some of the finished composition is still on the instruments and in the packed container when calculating the required amount.

How the surface affects the consumption

Plaster

You must estimate the thickness of the layer that will be coated later on and pre-evaluate the overall wall’s quality in order to determine how much plaster mixture will be used. It is necessary to determine if small areas with defects will be processed, or if the entire surface will be covered in putty.

A sufficient amount of 1 mm starting and 1/2 mm finish putty is applied for a smooth surface. The final materials must then be taken in quantities of 1000 g/m2 and 600 g/m2, respectively. As the layer thickness increases, so does the consumption; for example, an 11 mm layer requires 11 kg of "start" per square meter.

A repeat layer is occasionally needed; it is always thinner than the preceding layer and typically reaches 3 mm, but it is also considered when determining the flow rate.

An example of a calculation would be to place a wall that is mostly level and has a few small flaws. Base area: 15 m x 3 m. A 3 mm layer is needed. There are 1.15 kg of material per 1 mm coating, per the norms. Next, 3.45 kg – 3 mm. The finishing material quantity required can be calculated by multiplying the wall area by the consumption of one square meter. For us, 51.75 kg is equal to 15×3.45. The finished putty is covered with a 1 mm layer, which requires a little over 17 kg.

Drywall

Even though every single drywall sheet is perfectly even, there are joints between them that need to be covered up. Only finish putty will not do because the self-tapping screw hats used for installation must be hidden. The choice of material is contingent upon the conditions within the space:

• In wet, a cement putty is needed (1 m2 is 1100 g);

• For dry, choose gypsum or polymer (it will take 1000 g/m2 and 500 g/m2, respectively).

Applying primer to the gipper beforehand will reduce the amount of putty needed on drywall. Its basis determines the putty mixture’s volume.

1. Cement. The most costly option. 1 m. sq. It goes 1200 g.
2. Gypsum. Economic option. 1 m2 takes 1000 g.
3. Polymer. The material is expensive, but it is consumed economically. 1 m. sq. It goes 600 g.

Working with drywall makes calculations easier because the sheet’s size is known and the amount of defects that need to be fixed is minimal.

Concrete

Prime concrete surfaces prior to applying putty. Concrete should have a first layer no thicker than 6 mm and a second layer no thicker than 3 mm.

Other reasons

Putty layers on wooden surfaces should not be thicker than two to three millimeters. Before puttying, the tree is coated with a primer to increase its adherence.
