During a home improvement project, have you thought, "How long does it usually take the plaster to dry?" If you want to get the best results while plastering a wall or patching a hole in one, you need to know how long it will take for the plaster to cure.
Plaster's durability and sleek appearance make it a popular choice for exterior and interior applications. Drying times for plaster depend on some variables, including humidity, temperature, and the thickness of the applied layer.
Drying and curing time for plaster typically ranges from a few minutes to a few days. You may reduce drying time and increase the possibility of an effective plastering project by considering critical factors and using the right ventilation and moisture management strategies.
This article will explore the variables that impact plaster drying time and offer advice for speeding up the process.
Understanding The Plaster Drying Process
The drying process of plaster must be understood to estimate how long it will take to dry. Plaster is a combination of water, binders, & additives that are applied to a surface. Evaporation of the water causes the plaster to dry and harden over time. Curing is the term for this period.
Many chemical reactions take place within the plaster while it dries. Crystalline structures form as a result of a reaction between the binders there in the mixture and the water. The strength and longevity of the plaster are enhanced by these structures.
Changes occur in the plaster as the water evaporates. The initial softness and flexibility make it ideal for shaping and polishing. The plaster begins to harden and take on its final appearance and texture very slowly.
The plaster's drying time is highly conditional, considering not just the plaster itself but also the surrounding environment and, thus, the thickness of said coat being applied. As more of the thinner coat is in contact with air, it dries more quickly.
Plaster's dryness is not determined merely by whether or not the surface feels damp when touched. Plaster's interior moisture content is just as important. Time should be allowed for a full and consistent drying process to occur once the interior moisture has evaporated.
Knowing how long plaster takes to dry can help you set reasonable expectations and take the necessary precautions for the best possible outcome. We'll discuss what affects plaster drying time and why in the next part.
Plaster Drying Time Influencing Factors
Many variables affect how long it takes for plaster to dry. The drying process's estimation and management can be greatly improved with a thorough understanding of these elements. Let's examine the main causes that delay plaster's drying time:
Temperature
Plaster's drying time and success are both greatly affected by ambient temperature. The plaster's drying time can be shortened if the temperature is raised above the dew point. The drying process can be slowed down by lower temperatures. Plastering and drying are best accomplished when temperatures are kept within a narrow range.
Humidity
The time it takes for the plaster to dry depends on the relative humidity in the room. Plaster takes longer to dry because high humidity inhibits water evaporation. Drying time is reduced when humidity levels are reduced. Proper ventilation and dehumidification methods can assist in controlling humidity and speed up the drying process.
Plaster Thickness
Drying time is proportional to the thickness of a plaster covering. Thicker coats are less porous and dry more slowly than thinner ones. To guarantee appropriate drying and prevent concerns like cracking or uneven drying, it's vital to follow manufacturer instructions regarding the wall depth for every plaster type.
Ventilation
For plaster to dry quickly and properly, air circulation is crucial. The drying process can be sped up by ensuring adequate airflow is directed at the plaster. The air in a room can be properly ventilated through open windows, fans, or dehumidifiers. But, it is important to find a happy medium and prevent quick drying, which can cause problems like shrinking or cracking by limiting the amount of airflow.
Ambient Conditions
Drying time can be affected by environmental factors such as room temperature, humidity, and the amount of direct sunlight. Slower drying might occur in rooms with inadequate air circulation, and uneven drying and surface concerns can result from drying in direct sunlight. Plaster drying should be controlled and monitored to guarantee uniform and rapid drying.
Plaster drying times can be estimated more accurately, and drying conditions can be optimised if these parameters are considered. The drying times for the various plaster varieties will be discussed in the next section.
Various Plasters And Their Drying Times
Plaster comes in several forms, each with unique properties and drying time, and is utilised in building and remodelling tasks. Let's talk about the many kinds of plaster and how long it takes for each to dry:
Gypsum Plaster
Plaster of Paris, or gypsum plaster, is a common material due to its affordability, versatility, and ease of usage. Gypsum powder and water are the usual ingredients. The drying time for a thin application of gypsum plaster is typically between 24 and 48 hours. Certain paints may need more time to dry than others if they are thicker.
Lime Plaster
Lime plaster requires only lime, sand, and water as its three main components. Because of its durability and permeability, it is ideal for use in refurbishment initiatives. Lime plaster typically takes longer to dry than gypsum plaster. Lime plaster can take anywhere from a few more days to a few weeks to dry, depending on the thickness of the application and the environmental factors.
Cement Plaster
Plaster made from cement, sand, & water is known as cement plaster or stucco. Its outstanding resilience makes it a popular choice for external applications. Cement plaster's drying time varies greatly based on elements like coat thickness and ambient temperature and humidity. Drying time for cement plaster varies, although it usually takes several days up to a few weeks.
Clay Plaster
Natural clay, sand, & fibre combine to form clay plaster, a material lauded for its eco-friendliness, breathability, and aesthetic appeal. Clay plaster takes more time to dry than other varieties of plaster. Clay plaster, depending on its thickness and the surrounding conditions, may require several weeks or months to dry entirely. Working with ceramic plaster requires a lot of patience.
The drying mentioned above durations can shift depending on temperature, moisture, plaster thickness, and airflow. While working with plaster, you must always follow the instructions and advice provided by the manufacturer.
You may better plan your project and guarantee adequate drying before continuing with more development or finishing work if you are familiar with the oven drying of various types of plaster. In the following paragraphs, you'll find helpful advice for speedily curing plaster.

To ensure that the plaster is fully dry, you can check the moisture content using a moisture meter. Additionally, the plaster should feel cool and have a consistent colour throughout.
Advice On Effective Plaster Drying
Plaster must cure thoroughly to form a hard, long-lasting coating. Here are some helpful hints for speedy plaster drying:
- Maintain Optimal Temperature and Humidity: The drying area should be kept at room temperature with a relative humidity of 50 to 60 per cent. Temperatures between 20 and 25 degrees Celsius (68 and 77 degrees Fahrenheit) with relative humidity between 40 and 60 percent are prefered. The plaster will dry more quickly and uniformly under these conditions.
- Ensure Adequate Ventilation: For plaster to dry quickly and properly, air circulation is essential. Let in some fresh air by throwing open the windows and door. To improve ventilation, you can also utilise fans or dehumidifiers. Avoid creating too much airflow since this can hasten drying and lead to problems like cracking and shrinking.
- Avoid Direct Sunlight: Plaster can dry unevenly and develop surface problems if exposed to direct sunshine. Keep the drying space out of direct sunshine, and if that's not possible, use drapes or blinds to filter out what little sunlight there is. This reduces the potential for issues and helps keep drying conditions constant.
- Use Dehumidifiers: Dehumidifiers can be used in high-humidity settings to bring the relative humidity down. Plaster can dry more quickly with the aid of dehumidifiers since they remove excess moisture from the air.
- Follow Manufacturer Guidelines: Always use the plaster according to the manufacturer's instructions and recommendations. Drying durations, maximum thicknesses, and special precautions and instructions are all included in these recommendations.
- Be Patient and Allow Sufficient Drying Time: It's best not to speed drying. Make sure you give the plaster plenty of time to dry before moving on to the next step in the building process. If the drying process is rushed, the quality and durability of the plaster may suffer.
- Monitor the Moisture Content: Check the moisture level in the plaster with a moisture metre. This aids in making sure the plaster is completely dry before finishing. By measuring the relative humidity inside, a moisture metre gives a more precise picture of how far along the drying process is.
By following these guidelines, you may ensure that the plaster dries quickly and thoroughly. Drying plaster correctly ensures a smooth finish and reduces the likelihood of future problems. Common blunders that can occur when plaster is drying will be discussed in the next section.
Common Errors To Prevent
Some errors can slow the plaster drying process and lower the quality of a finish. Some typical blunders are as follows:
- Insufficient Drying Time: Not waiting long to allow the plaster properly dry is a common mistake. Cracks, poor finish adhesion, and structural weaknesses might result from rushing the job. To guarantee proper drying, adhere to the manufacturer-recommended drying time.
- Applying Finishes Too Early: Plaster must dry completely before finishing materials may be applied, or they risk peeling, blistering, or even mould formation. Before applying any ornamental or protective finishes, wait till the plaster is dry, both inside and out.
- Inadequate Ventilation: The drying process can be slowed down if there isn't enough airflow in the designated drying area. Opening windows, utilising fans, or hiring dehumidifiers can all help with air circulation, which in turn helps with moisture evaporation. Drying times are cut in half, and humidity is kept at bay when ventilation is adequate.
- Excessive Heat: Plaster can cure faster with heat, but if you use too much of it, it will shrink, crack, and lose its structural integrity. Please avoid direct heaters and guns, as they produce dangerously high temperatures. Drying is best accomplished with natural airflow and temperate temperatures.
