It can be difficult to plaster in a cold, unheated room in the winter, especially when the temperature drops considerably. A common question among builders and homeowners is whether successful outcomes can be attained without the use of heating. It is essential to comprehend how temperature affects the plastering process in order to guarantee a smooth and long-lasting final finish.
Plaster may have trouble setting properly at very low temperatures, which can result in cracks, poor adhesion, and other problems. However, plastering in cold weather is still feasible with the appropriate technique and understanding of temperature limitations.
This article will discuss whether plastering in a cold, unheated space is feasible in the winter and what temperature range is best for indoor plastering. Even in difficult circumstances, you can guarantee the success of your plastering project by adhering to these recommendations.

Plastering in winter and summer
Navigating pages
Plastering is a common practice during the warm season.
The following details provide an idea of the temperature range in which plastering can be done, as well as tips for extending the building season.
Subjective in nature, the information is given as long as the solutions include the right modifiers in the necessary ratios.
Features of plaster
The plaster mortar’s name is determined by the binders’ composition and proportions:
- Gypsum;
- Gypsum-lime;
- Lime-sand;
- Lime-cement;
- Cement-sand.
As a filler, different kinds of sand are employed. A wide range of temperature application modes and diverse technical characteristics of the mixtures are ensured by special additives.
Dry gypsum sheet plasters, or gypsum plasterboard (GKL), are available separately.
At what temperature can you plaster the walls inside the house
The temperature range for working with gypsum plasters is +5˚ to +30˚C.
Plastering inside a building that has frozen walls during the winter can only be done once the wall has thawed to a depth of half.
When using solutions in winter, antifreeze modifiers do not need to be added if the air inside the building has warmed up to a temperature higher than +10˚C.
It is required to evenly moisten the plastered surface if the indoor air temperature is higher than +23˚C.
Maintaining humidity in the plastered areas and adding special plasticizers are necessary in summertime dry and hot weather with temperatures above 30˚C and humidity below 50%.
Is it possible in winter in an unheated room
There are mixtures of lime plaster and lime cement; the ideal air temperature for these materials is between -10˚ and +25˚C.
Plastering with such mixtures requires that both the application surface and the solution itself be heated to a temperature of at least +5˚C.
If the daytime temperature falls below +5˚C, the mixture should be prepared in a heated area of the building. If not, it should be prepared at night.
At what temperature is it possible if there is no heating
It is possible to plaster buildings in below-freezing temperatures. Cement and lime are occasionally added to mixtures along with antifreeze ingredients.
Modifier | ambient temperature ˚С | in proportion to the weight of the binder % | |
from | to | ||
Potato carbon | 0 | -5 | 5 |
-6 | -15 | 10 | |
-16 | -30 | 15 | |
Sodium nitrite | 0 | -5 | 5 |
-6 | -9 | 8 | |
-10 | -15 | 10 | |
Calcium nitrate with urea | 0 | -5 | 5 |
-6 | -15 | 10 | |
-16 | -25 | 15 |
It is preferable to prepare aqueous solutions with the necessary percentage content and pour them into the prepared composition to lessen the labor intensity.
Sodium nitrite, calcium nitrate with urea, or potash cannot be used as frost-resistant additives when plastering a building that is operating at a temperature above 40 °C or has a high humidity content (above 60%).
Building a wall outdoors
In the event that the temperature falls between -30˚ and +5˚C and there is no wind, plastering can be done outside. Not below +5˚C when using water-based mixtures without frost-resistant additives.
Temperature conditions inside the house
Sheet gypsum plaster installation can be done on:
- metal lathing;
- wooden frame;
- adhesive pad.
In order to prevent perspiration where there is metal contact, it is preferable to install on a metal frame during a positive temperature.
It is best to install on an adhesive base and to prime and fill seams when the interior building temperature is at least +10˚C.
While difficult, plastering in a cold, unheated room in the winter is not impossible. Avoiding freezing temperatures is crucial because they can impede the plaster’s ability to bond and dry. Plastering ought to be done at a minimum temperature of 5°C (41°F) in order to guarantee adequate adhesion and curing. To get the best results, you might need to wait for warmer weather or use temporary heating if the temperature falls below this.
What will happen if you do not observe the temperature regime
The plastered walls become wavy and lose their plane when there is a brief, small deviation from the temperature regime. More severe technology infractions include a layer’s strength being lost, its adhesion to the supporting layer being reduced, cracks appearing, and eventually the layer collapsing.
Read the factory instructions if you plan to use factory plaster mixes. The ideal temperature range for plastering inside a house is +10 to +30˚C. Outside plastering in temperatures below +5˚C requires calm weather conditions or the installation of a protective vestibule. Use caution when adding anti-frost modifiers.
Question | Answer |
Can you plaster in an unheated room in winter? | Yes, but it is risky. The plaster might not set properly, leading to cracks or other issues. |
At what temperature is it best to plaster inside the house? | The ideal temperature for plastering is between 5°C (41°F) and 30°C (86°F). Below 5°C, the plaster may not cure correctly. |
While plastering in a cold, unheated room in the winter can be difficult, it is not impossible if the proper safety measures are taken. Temperature is a crucial consideration. For plaster to properly dry and stick to the surface, it needs to be somewhat warm. Plaster may not set properly in a very cold room, which could result in cracks or weak areas.
When plastering, the ideal room temperature is to be kept above 5°C (41°F). Anything less may lead to inadequate drying circumstances. Consider using makeshift heaters or postponing the plastering project until the weather gets better if you don’t have access to heating. It’s crucial to keep in mind that the walls themselves may still be chilly, which could have an impact on the plaster, even when the outside temperature is above freezing.
In conclusion, even though you can plaster in a cold room in the winter, it’s important to keep a careful eye on the temperature. Better outcomes and a more resilient finish can be achieved by making sure the room remains sufficiently warm both during and after application.
