Functions of warm plaster for facades
This kind of facade plaster is made up of a dry mixture that includes cement sand, glue, and different plasticizers. The primary components of this material are hollow materials (sawdust, foam glass particles, and granulated polystyrene foam), which give the plaster its ability to insulate against heat.
Plasticizers aid in preserving the material’s elasticity, resistance to temperature changes, and ability to withstand cracking.
The mixture’s polymers help to increase its resistance to mechanical stress.
Facade insulation using a plaster mixture
Warm facade mixtures are substantially lighter than traditional facing mixtures, but they become much heavier when multiple layers are applied; for this reason, additional reinforcement of the foundation is required. Warm plaster has pros and cons, just like any other material.
Advantages
This facing material’s primary benefit is its ability to insulate against heat. The material keeps cold air out of the space and helps the walls retain heat.
Furthermore, warm plaster
- easy and quick to apply;
- does not require the use of reinforcing mesh, which reduces costs;
- does not require wall leveling;
- has good adhesion properties to any surface;
- no cold bridges are formed during coating;
- prevents the appearance of rodents;
- the main composition of the mixture is of natural origin;
- frost-resistant;
- has vapor-proof properties;
- waterproof;
- has soundproofing properties;
- is an environmentally friendly material.
Furthermore, the facing mixture is long-lasting and doesn’t need special maintenance. It is feasible to reduce the insulation’s thickness because of insulation with this composition.

Flaws
The primary drawback with heat-insulating plaster is the extra design required: the surface needs to be primed and then covered with a decorative coating.
Furthermore, the material’s overall mass following application has a sizable weight.
Warm plaster, which doesn’t need to be coated again, is rather expensive.
Areas of application of warm plaster
In addition to being used to adorn a building’s façade, insulated plaster can be used for the following purposes:
- for the purpose of sealing cracks;
- for insulation of building walls;
- when sealing floor joints, as well as for insulating floors and ceilings;
- for the purpose of insulating the basement of the building;
- when designing window slopes and doorways;
- for insulation of sewer risers for cold and hot water supply.
Furthermore, this mixture is utilized for interior painting in addition to exterior decoration.
Types of warm plaster
Warm plaster is categorized based on the mixture’s makeup. As a result, it is typical to categorize the content into types:
- containing granulated polystyrene foam. Suitable option for facade and exterior work;
- containing sawdust impurities. The composition of this type includes paper, cement, clay. It is advisable to use this mixture for interior work;
- containing vermiculite (or perlite). This mixture has good antiseptic properties and is optimal for external use.
If gypsum is the binding ingredient in warm plaster, this combination should only be used for interior construction.
Cement is the primary component of the most appropriate mixture, which can be used for both internal and external work.
Preparatory work
It is best to prepare the walls for work before applying warm plaster.
To accomplish this, you’ll need:
- remove protruding elements in the wall: pieces of reinforcement, brick or concrete protrusions;
- if there was an old coating on the wall (paint, putty), it should be removed;
- if there is insulating material or sand in the panel joints, everything must be cleaned;
- if there are cracks in the wall, they need to be sealed with sealant;
- degrease and clean the wall surface from dust;
- treat the wall with primer liquid.
It is advised to apply a thin layer (between 3 and 5 mm) of the mixture after the primer has dried in order to maximize the adhesion of the solution to the base.
When the weather is dry, the putty mixture dries completely in a day or two, at which point you can begin applying the main layers.
Mixture consumption
On the material packaging, there is a measurement of the facing mixture consumption per square meter.
The amount of material needed is decided by the thickness of the layer being laid:
- with a layer thickness of 2.5 cm, the material consumption will be 10 – 14 kg per m²;
- with a layer thickness of 5 cm, the material consumption will be 18 – 25 kg per m².
You can ascertain the material’s cost per square meter in addition to its consumption.
A warm layer of 0.5 cm is the optimal thickness for soundproofing. To reduce sound, fibrous materials are advised, and the heat-insulating mixture is more frequently utilized as insulation.
DIY warm plaster application technology
The ideal weather for facing work on the facade is warm, dry, and windy.
Prior to application, the solution needs to be combined right away. Dissolve the dry mixture in a large container according to the manufacturer’s instructions and stir for a few minutes. To achieve homogeneity, wait for approximately ten minutes and then stir the mixture once more.
up to four hours.
To prevent hardening, it is advised to apply the composition heavily.
The following is how the solution is used:
- beacons should be installed at a distance of 50 cm to obtain an even layer;
- it is advisable to first apply the solution with a small spatula, then with a large one. The mixture is applied from bottom to top. After covering a meter – one and a half walls, the applied solution should be aligned with a rule;
- the surplus removed by the rule can be reused;
- After applying the coating, the beacons should be removed, holes from them – seal with mortar and level the surface.
Even though warm plaster is malleable, a thick layer of it can crack. Two centimeters is the recommended layer thickness to prevent the mixture from sliding down. It will take enough time to finish the coating in multiple layers because each layer is applied on top of the one that has fully dried before it is applied again.
Nonetheless, if the first layer is 4 cm or thicker, the following steps must be taken in order:
- The first layer is covered with a reinforcing mesh two hours after its application;
- apply a thin layer of the mixture onto the reinforced mesh and profile with a notched trowel;
- after 24-48 hours, apply a second layer of solution similar to the first.
Experience has shown that a 5 centimeter layer is sufficient to achieve the desired outcome. This layer has characteristics unique to this kind of coating, including thermal insulation.
In the event that more decoration is required, the facing coating is fully dried before being applied.
The warm plaster should be coated with a primer solution before being used.
Warm plaster, then, is a supplementary heat-insulating material that can be used to reliably insulate a building’s walls in addition to serving as an external coating that safeguards the facade. Simultaneously, it is feasible to lower the primary insulation layer’s cost and adorn the walls with extra decorative coating.
Applying warm plaster won’t be a difficult task to complete. Furthermore, this kind of coating doesn’t need to be leveled further and blends in nicely with any type of wall.
There are benefits and drawbacks to selecting warm plaster for your facade. Positively, warm plaster offers superior thermal insulation, which can lower heating costs and help control indoor temperature.
