Consumption of decorative plaster per m2

Decorative plaster is a popular option that is long-lasting and visually appealing for adding texture and style to walls. However, it’s important to know how much material you’ll need before beginning any project. Knowing how much decorative plaster is used per square meter will help you set realistic budgetary goals and cut down on waste.

The amount of plaster needed can vary depending on a number of factors, including the type of plaster, the state of the wall surface, and the application technique. You can guarantee a flawless application process and a stunning finish that lives up to your expectations by taking these factors into account.

Type of Plaster Average Consumption per m2
Textured Plaster 2-3 kg
Venetian Plaster 0.5-1 kg
Silicone Plaster 1.5-2.5 kg
Mineral Plaster 1.5-2 kg
Acrylic Plaster 2-3 kg

Planning and budgeting for the application of decorative plaster depend greatly on knowing the consumption per square meter. Depending on the type of plaster, surface texture, and application technique, different amounts may be required. You can make sure you purchase the appropriate quantity of material, prevent waste, and get the desired finish without incurring unforeseen expenses by being aware of the precise consumption rate.

Types of decorative plaster

Dry mix solutions are used for interior wall and facade finishing. Imitations of natural stone, wood, fabric, and decorative plaster are used to create an unusual surface effect. The amount of dry matter consumed per square meter is proportionate to the amount of liquid in the solution, and the factory packaging specifies the mixture’s intended use.

Ready-made plaster solutions are also available from specialized stores. The mixture can be used right away when diluted in water or solvent, but the cost of the finished product is higher than that of the dry mixture.

The components of decorative dry plaster consist of lime, sand, cement, and extra granules. These are tiny fragments of mica, shells, wood fibers, stone, marble, granite chips, and other fillers. These ingredients give the mixture the appearance of more volume after the coating has dried and solidified. In addition to improving the interior’s aesthetics and visual appeal, the relief texture helps to hide wall flaws.

Decorative mixes from reputable producers are particularly well-liked in the home finishing materials market:

The amount of decorative plaster used per square meter is determined by each manufacturer based on the kind, composition, and properties of the component.

Crucial! For home repairs, purchase mixtures from reputable, trustworthy, and serious brands. Consider the outlet’s reputation and request a certificate of quality and standard compliance from vendors. The properties and characteristics of the mixture are adversely affected by transportation or violations of warehouse storage conditions. If you buy the material from a dishonest vendor, you run the risk of having the walls’ appearance ruined, receiving the incorrect solution consistency, or having the curing period lengthened.

Decorative plaster types are categorized based on the type of binder and filler used. Plaster can be classified as textured, Venetian, or structural based on the type of filler used. Of these three varieties, one has a smooth coating (Venetian), and the other two provide relief surfaces (structural, textured).

The following types are separated based on the binding ingredient:

  • acrylic;
  • silicate;
  • silicone;
  • mineral.

The type and intended use of decorative plaster determine how much of it is consumed.

  1. Acrylic plaster is made on the basis of a high molecular weight polymer (acrylic resin) and is characterized by increased elasticity.
  2. Silicate plaster is produced on the basis of liquid glass (compounds of potassium hydroxide, alkali potassium carbonate, quartz sand). Characterized by water-repellent properties, resistance to putrefactive bacteria and mold formation, durability.
  3. Silicone variety of decorative plaster – a composition based on synthetic resin, resistant to ultraviolet radiation and moisture. Effectively used for cladding facades.
  4. The main component of the mineral mixture is cement.Characteristic properties: strength and UV resistance.

How to calculate material consumption for plaster

The instructions on the original packaging serve as the starting point for figuring out how many bags to use or how much the mixture weighs in kilograms. The mixture volume needed to cover a square meter of wall surface in a layer of one centimeter is shown in the table. However, the master’s preferences, the type of finishing, the wall’s material, and its condition all affect how thick the layer is. As a result, measure the walls, ascertain the size of the work surface, and ascertain the layer’s thickness before making the purchase.

Crucial! The application of plaster to a level, solid surface is assumed for all information regarding the use of decorative mixture in the manufacturer’s instructions (after leveling the walls and priming).

Determine the kind of material and finishing style first, then figure out how much will be used. In a room that is both large and small, on the sunny and shaded side, decorative plaster appears different. Consider whether the item(s) you had originally intended to purchase fit you. Create a trial application and sketch a small section on a discrete wall section. Examine the subsequent points:

  • is the selected texture suitable for the room (karakul, fur coat, map, roller, wet silk);
  • how harmoniously the imitation of glossy marble or brick will fit into the interior;
  • do the color and texture of the plaster match the style of the doors and windows.

If you are comfortable with your decorative plaster selection, estimate consumption and add 5–10% to it. A portion of the losses can be attributed to the solution spilling onto the ground, tool residues solidifying, concealed wall flaws, and greater porosity.

Calculation examples

The thickness of the material layer and consumption are decided by the size of the filler fractions. The amount of decorative textured plaster that is consumed per square meter ranges from 0.9 to 1.5 kg; the granules in this mixture have a size of 1-3 mm. A layer of structural mixtures is applied in accordance with the grain size:

  • With quartz chips – 2.5-3 kg per 1 m2. For a wall with an area of ​​10 m2, 2 bags weighing 25 kg are required.
  • Acrylic paste – grain 1 mm: 2.5 kg per m2; grain 2 mm: 3 kg per 1 m2. For a single-layer coating of a wall with an area of ​​10 m2, you will need 2 containers weighing 15 kg.
  • With marble chips (grain 1-3 mm) – 1 kg per 1 m2. Single-layer coating of a wall with an area of ​​10 m2 – 1 bag weighing 25 kg.
  • Bark beetle – 2.4-4 kg per 1 m2 (depending on the size of the fraction).
  • Bark beetle "Starateli" – 9 kg per 1 m2 (layer 1 cm thick).
  • Bark beetle "Volma" – 6 kg per 1 m2 (layer 1 cm thick).
  • Venetian – 70-200 g per 1 m2 (on a perfectly flat surface).

The amount of material doubles when decorative plaster is applied in two layers.

You’ll be in a better position to determine how much decorative plaster you’ll need for your project once you’ve taken into account the factors that affect its consumption. Buying a little extra is usually a good idea in case of errors or variations in surface texture.

Keep in mind that the amount of material you use will depend on the type of plaster, the state of the walls, and the application method. Anticipating and comprehending these factors can assist you in preventing mid-project shortages.

By having a thorough understanding of these elements, you can guarantee a more seamless and effective application, resulting in a stunning finish that improves your area.
