The drying times of various putty types are important to know when doing renovations and home improvement projects. Determining the drying time for various materials, such as acrylic putty, gypsum, and wall finishes, can facilitate more effective project planning and prevent issues.
Before painting a wall, finishing putty is frequently used to smooth out any imperfections. It produces a perfect surface, giving the finished paint job a polished and tidy appearance. This kind of putty usually dries pretty quickly, so you can continue working on your project without having to wait a long time.
On the other hand, larger holes and cracks are often filled with gypsum putty. Its thickness and composition cause it to dry differently than finishing putty. When working with gypsum putty, patience is essential because hurrying the process can result in cracks or an uneven surface.
Acrylic putty is renowned for being long-lasting and flexible. It is frequently utilized in locations that could see minor alterations or movements. Generally speaking, acrylic putty takes a little longer to dry than finishing putty, though this can vary depending on the brand and surrounding factors. But the long lifespan and resistance to cracking make it well worth the wait.
The drying times of each type of putty vary depending on the application thickness, humidity, and temperature. You can better manage your renovation schedule and get the best wall results by being aware of these drying times.

Influencing factors
Many variables affect how long putty takes to dry on walls.
Environment
Putty dries at varying rates depending on external factors. A temperature of +18–+20°C, a humidity of no more than 65%, and the absence of drafts in the space are necessary for the material to harden. Noncompliance with these guidelines may have an adverse effect on the coating’s quality as well as the mixture’s rate of drying.
Humidity in the room
A room with higher humidity will take longer for the hardening process to complete.
Air permeability
Drafts should be prevented, but the room should be ventilated.
Thickness of the putty layer
Utilizing a spatula, the mixture is applied to the wall in two layers. The putty shouldn’t be more than one centimeter thick.
To what extent the finishing putty dries is a question that many ask. Wait 10 to 20 minutes after finishing to allow the material to slightly solidify. The wall is then polished using fine sandpaper. Read the directions on the package carefully before applying the mixture (the drying time varies depending on the manufacturer and composition).
Surface
Prepare the base before beginning any work; it needs to be strong, dry, and free of dust, greasy stains, and paint residue. Before plaster and putty are applied, porous areas and other wall imperfections are sealed with a sealing primer. After finishing, a hard brush is used to clean the surface and get rid of any small particles that are sticking out.
Varieties and which one is better to choose
Before applying wallpaper and decorative coatings, putty is a must. It enhances adhesion in addition to making the surface smoother. Plastic material should be applied to wooden walls, particularly those that are under mechanical stress. There is a chance of unevenness if the base is not puttied, and this risk increases if the finishing layer is thin.
There are many different kinds of solutions with various features available on the market. Depending on their composition, they are utilized in both wet and dry environments.
- dry quickly;
- have good ductility;
- easy to apply;
- resistant to mechanical and atmospheric influences;
- help eliminate minor defects and smooth the surface well.
Mixtures are categorized based on the kind of material, application technique, and quality.
The market offers the following compositions: alkyd, lime-cement, acrylic wood putties, and others with the addition of polymers and other fillers (which improve the material’s uniform drying and increase its elasticity).
The products are applied to metal and wooden components, plasterboard (gypsum plasterboard), walls made of lime and sand, and concrete. Putties with fiberglass and other ingredients to enhance the material’s qualities are sold commercially.
Mixtures that are ready-made or dry (powdered) can be bought. In the second scenario, make the solution yourself while adhering to the manufacturer’s recommended proportions as listed on the packaging. The ingredients are thoroughly mixed and diluted in accordance with the directions (until a homogeneous mass is obtained).

Wall putty (finishing, gypsum, or acrylic) can take different amounts of time to dry depending on a number of variables, such as the kind of putty used, the application’s thickness, and ambient elements like humidity and temperature. While acrylic putty may take up to 72 hours to dry, gypsum putty typically dries in 24 to 48 hours. Applying multiple coats of finishing putty is common, and each coat must fully dry before applying the next. Always adhere to the manufacturer’s instructions and take your project site’s unique conditions into account for the best results.
Accelerating the drying of the starting and finishing putty layer
- Type of mixture. To speed up the drying process of the putty, choose latex-based compositions. Aqueous mixture hardens faster (up to 72 hours). Material containing linseed oil takes a long time to dry: it takes several weeks to form a thin layer of film. It takes up to 2 weeks for window putty to harden.
- Environment. To speed up the process, specialists choose optimal conditions (for finishing). Try to do the work in dry, sunny weather.
Some artisans use a hair dryer set to low speed to expedite the drying process. Take care that the putty does not crack or harden too quickly.
The use of a hair dryer, heating, and other techniques to expedite the process is not advised by many experts, though, as these methods only help to dry the top thin layer. Furthermore, there is a greater chance of surface cracking when employing this method, which could lower the decorative coating’s quality. Experts advise waiting for natural drying because of this.
How to determine if the putty has dried before painting
When applying a decorative coating, feel the material with your fingers to determine how sticky it is. The mixture has dried if the finish is unbroken and leaves no trace.
- After hardening, the putty changes its color (becomes lighter).
- The surface becomes uniform (due to the presence of cracks and other defects on the wall, layers of different thicknesses are formed, having an uneven color).
It’s essential to know how long putty takes to dry in order to achieve a smooth, long-lasting wall finish. Under normal circumstances, finishing putty—which is usually used for minor imperfections—dries in about 24 hours. Temperature and humidity, for example, can prolong this time.
Because of its ability to dry quickly, gypsum putty can be prepared for painting and sanding in six to twelve hours. Because of this, it is a well-liked option for tasks requiring quick turnaround times. Even though it dries quickly, it’s crucial to apply it correctly to prevent cracks and uneven surfaces.
Acrylic putty works well on a range of surfaces because of its flexibility and durability. Depending on the layer’s thickness and the surrounding conditions, it can take anywhere between 24 and 48 hours to dry. When using acrylic putty, patience is essential because hurrying the drying process can result in a lower-quality finish.
In conclusion, depending on the type and application conditions, finishing, gypsum, and acrylic putty have different drying times. Understanding these variations enables you to plan your project’s timeline efficiently and produce a polished, long-lasting product. To get the best results for your walls, always take the putty’s particular qualities into consideration.
