Selecting the appropriate plaster for your walls is essential to attaining both visual appeal and long-lasting functionality in your house. In addition to adding aesthetic value to surfaces, plaster shields them from damage such as moisture, cracks, and other wear and tear. With so many options, choosing the best plaster requires taking into account things like the type of wall you have, the finish you want, and your maintenance preferences.
The kind of wall you’re working with is one of the most important factors to take into account when selecting plaster. Certain kinds of plaster may be needed for various wall materials, such as drywall, concrete, or brick, in order to guarantee good adhesion and durability. Knowing the makeup of your wall will help you choose a plaster that will adhere well, offer the appropriate degree of protection, and look good.
The environment in which the plaster is to be applied is another important consideration. Moisture-resistant plasters are necessary in high-humidity areas like bathrooms and kitchens to stop the growth of mold and mildew. However, for a tidy, inviting atmosphere in living rooms or bedrooms, plasters with smooth finishes and low maintenance requirements might be chosen.
When selecting plaster, take into account the texture and finish you want for your walls. Plasters can have decorative finishes like Venetian plaster or be smooth, textured, or a combination of these. Your choice of finish can greatly influence how your room looks and feels overall, adding character and style to suit your tastes.
Lastly, consider long-term durability and maintenance needs. Keeping your walls looking good over time requires knowing which plasters are easier to maintain and repair than others. Plasters differ in terms of durability as well. Some are more resilient to impact damage or cracking than others, which makes them ideal for high-traffic areas or homes with kids and pets.

Criteria for choosing plaster
The variety of dry and ready-made plasters available in the market makes selection challenging. What then is useful for plastering walls? You can select the appropriate plaster mix type with the aid of the following selection criteria.
1. Application area. Plaster is used for insulation of facades, leveling walls both inside and outside, and in wet and dry rooms. You can use dry, ready-made plaster indoors made of different polymers, gypsum, or cement.
Cement-sand plasters are used outdoors on the facades of private homes and apartment balconies. Cement-lime plaster is used in high-humidity areas (kitchen, bathroom).
External wall insulation is installed using cement mortar mixed with perlite. Fiber-reinforcing fiber can be used to raise the plaster’s quality. Either purchase pre-made reinforced mixtures or add it yourself (the process is outlined in the work "Fiber fiber for floor screed").
2. The warmth. This is a crucial criterion for donation. Frost ruins interior gypsum plaster in the winter when the room isn’t heated. As a result, here cement, sand, and water are required.
3. Size of sand fraction. Sand grains can be used in three different sizes: larger for tiles and wallpaper, medium for painting, and smallest for decorative plaster. If the wall has chips and potholes, a fine portion of sand is also required. As a result, you should check the packaging for information on the area of application or the size of the sand when buying dry solutions. Make sure to clarify these details with the seller if there is any uncertainty.
4. The experience of the master. Ask the contractor how experienced he is with different plasters before making any purchases. It’s thought that a professional needs to be proficient with all kinds of plaster mixtures. However, this is untrue—a large number of extremely skilled plasterers exist.
Cement mortars are preferable if you intend to do the work yourself. In this situation, you can practice tossing the solution onto a small patch of wall using the proper motions. A training course of this kind won’t cost a lot like gypsum plasters.
5. Technique of application. Only cement mortar can be used for machine plastering outside of buildings; dry gypsum mixtures can be used within.
6. The factor of material cost. A smooth wall surface is the ultimate goal, which is accomplished with both pricey polymer plasters and inexpensive cement mortars. However, in this case, it’s also essential to consider the cost and pace of the work. As a result, it’s essential to take everything into account.
When selecting plaster types for interior decoration, you should consider the cost, the area to be covered, the craftsman’s skill level, and the application method.
Choosing plaster by rating
The majority of dry mixes meet the specified requirements, so an unprepared customer is almost always faced with a dilemma when purchasing building materials online or in a specialty store. In this situation, what should I do? If only the name is known, which wall plaster is better? Here, there are two methods:
- focus on popularity among the population;
- buy based on its operating conditions and technical characteristics.
Based on statistics regarding the volume of building materials sold in 2017, the following rating is given to the sales of dry plaster mixtures:
- "Knauf"
- "Volma";
- "Ceresit"
- "Unis"
- "Osnovit";
- "Glims";
- "Prospectors";
- "Caparol";
- "Mapei";
- "Betonit".
A slightly different rating result is obtained when selection is based on application conditions, area of operation, and price (as determined by qualified builders):
| Name | Consumption kg/m 2 with a layer thickness of 1 mm | Region applications |
Bag, kg | Compound | Price from, rub. |
|---|---|---|---|---|---|
| Ceresit ST 29 | 1.8 | Concrete, brick walls |
25 | Cement, sand, mineral additives | 470 |
| Volma Canvas | 0.9-1.0 | Concrete, brick, aerated concrete, foam concrete walls |
thirty | Gypsum | 320 |
| Prospectors | 1.2-1.3 | Wet areas, concrete, brick |
50 | Cement, sand, mineral plasticizers | 420 |
| Knauf Rotband | 0.8 | Concrete, brick, cement plaster, DSP | 30 (5, 10, 16,) | Gypsum | 410 |
| Caparol Capatect Leichtgrundputz | 1.2 | Light brick, expanded clay, pumice, porous concrete |
25 | Mineral | 750 |
For comparison, the higher specific gravity of cement compared to gypsum accounts for the higher consumption of Ceresit ST 29 plaster in kg/m2.
The customer will select the type of plaster for the walls based on the information provided.
Reliable manufacturers
The following well-known companies should be your first consideration when deciding on the best method for plastering interior walls: "Knauf," "Caparol," and "Ceresit." They are of excellent quality, but the price is also high.

Plastering the interior walls of the house can be made easier by analyzing the specifications for plaster and using the information supplied on various kinds of dry mortars.
Selecting the appropriate plaster for your walls is essential to getting a long-lasting and beautiful finish. Whether you are working on new construction, renovation, or walls that are indoors or outdoors, start by analyzing the unique requirements of your project. Every kind of plaster has benefits of its own. While gypsum-based plasters provide smooth finishes perfect for interiors, cement-based plasters are robust and appropriate for exterior use.
Evaluate the surroundings after that. Moisture-resistant plasters, like those based on cement or acrylic, are necessary in high-humidity areas like kitchens and bathrooms. Versatile gypsum plasters are a good choice for typical living spaces. Knowing these things will guarantee that your walls hold up over time and don’t deteriorate.
Take into account the application method as well. While traditional plaster mixes are preferred by professionals due to their flexibility, ready-mixed plasters are more convenient for do-it-yourself projects. A smoother and more effective plastering process is ensured by selecting the appropriate application technique.
Last but not least, finances and upkeep are crucial factors. Purchasing high-quality plaster can reduce long-term maintenance and repairs, even though the initial costs can vary. Your walls’ lifespan can be increased with routine inspections and small repairs, preserving their structural integrity and aesthetic appeal for many years to come.
Selecting the appropriate plaster for your walls is essential to attaining both visual appeal and longevity in your house. This article examines the important variables to take into account when choosing plaster, covering varieties like gypsum, lime, and cement-based plasters, all of which have special advantages in terms of application ease, breathability, and moisture resistance. We’ll also go over how different plaster types work best with different wall finishes and how important it is to select materials that take the budget and environmental factors into account when designing a project. Knowing these elements will help you make wise decisions for a successful wall plastering project, whether you’re building new or renovating.
