Knowing how long different types of primers take to dry is crucial when it comes to priming surfaces for painting. The primer’s drying time can affect the overall finish and timeliness of your project, regardless of whether you’re working with walls, ceilings, or other surfaces. Depending on their composition and the kind of surface they are applied to, primers dry at different rates.
For example, deep penetration primers are made to get into porous surfaces and give the paint a strong foundation. These primers are frequently applied to untreated wood, concrete, and brick. Their drying time can vary because they seep into the material, but generally speaking, it takes longer than with other primer types.
Dispersion primers, sometimes referred to as latex or water-based primers, are well-liked for their user-friendliness and speedy drying times. Plaster and drywall are among the surfaces that these primers work well on. They often become ready for the next coat in a matter of hours, and they are renowned for their low odor and quick drying time.
Oil-based alkyd primers are renowned for their robust adhesion and long-lasting qualities. They are frequently applied to materials like metal or previously painted wood that call for a strong, resilient foundation. But because they usually take longer to dry and smell stronger, it’s important to have enough ventilation when applying them.
Because of its versatility, acrylic primers are frequently used on surfaces both inside and outside the home. They are compatible with a variety of topcoats and dry rather quickly. They are an excellent option for surfaces that are subjected to changes in moisture content and temperature because of their flexibility.
The moisture content of the surfaces must be taken into account when priming plaster and putty. Before priming, freshly applied putty and plaster must be totally dry since any remaining moisture may interfere with the primer’s adhesion and drying speed. Depending on the particular product and the surroundings, a primer on these surfaces usually dries in a few hours to overnight.
A seamless and effective painting process can be achieved by being aware of the different primers’ drying times. It enables you to efficiently plan your project and prevents premature paint application, which can result in subpar adhesion and finish. The manufacturer’s instructions should always be followed for the best results and a perfect finish.

What is a primer
Primer is a special mixture that makes finishes adhere better to one another. Furthermore, the mixture’s antifungal composition prevents the growth of mold.
The amount of paint, glue, or finish plaster used on the primed surface is substantially less. However, you must wait for the primer to completely dry before it can acquire its properties.
The type of primer and the surface it is applied to determine how long it takes to dry. Deep penetration primers are perfect for porous surfaces because they typically dry in a few hours. Dispersion primers work well for drywall and dry quickly. Alkyd primers work best on metal or wood, but they can take longer—up to 24 hours. Popular for their versatility, acrylic primers normally dry in approximately one hour. The drying time of putty or plaster may differ depending on the surrounding temperature and humidity levels. A seamless, efficient painting process is ensured by being aware of these drying periods.
What depends on the drying time?
The drying time is influenced by multiple factors:
- Type of primer. The mixture differs in composition, respectively, the time of drying is also different.
- Wall material. Since the materials are distinguished by the ability to absorb moisture, time will vary from several hours to several days. Dry faster on porous dry surfaces.
- The number of layers of primer.
- Air temperature and humidity in the room where work is carried out.

Types of primer
There are two kinds of primer available:
- In the form of a dry mixture that must be diluted with water;
- In a liquid form, already ready for use.
Up to one centimeter of the composition can be seen below the surface. They are separated based on the depth of penetration into:
- Deep penetration. Applied to wooden and porous walls. Dry during the day.
- Quickly dry. Suitable for metal surfaces. Drinking from one to four hours, depending on the number of layers applied.
- Universal adhesive compositions. Applied to any type of surfaces. Dry from 4 to 10 hours. Time also depends on the number of layers applied.
- Concrete contact. Applied to concrete walls, more often used for external work. Dries from 12 to 24 hours.
- Olifa. Used for wood work. Dries at least a day.
Drying time on various surfaces
It is important to take into account the type of primer and its drying time when working with various surfaces. Use a specialized moisture meter to determine whether the layer can be maintained.
In the event that you do not have access to such a device, it is advisable to refer to the manufacturer’s instructions found on the packaging.
Construction spatula
Plaster
Because plaster is made of sand and cement, it has a high absorption rate. Thick layers of primer are applied to the walls; after processing, there shouldn’t be any dry spots. In four hours, one layer dries completely.
Sand concrete
You cannot wait for the tiles to fully dry out if tile installation is planned in the future. In this instance, the dust will settle and not hinder the work.
Putty
Burned walls must be reclaimed. If not, the material greatly increases the amount of paint or glue needed for additional work.
- The primer layer should be thin.
- Otherwise, cracks may form on the wall.
- The deadline for drying one layer in this case is 3-4 hours.
Acrylic putty
Drywall
One layer of coating is sufficient because the material absorbs moisture well. dries in approximately three hours at 20 degrees Celsius and relative humidity.
- If you need to apply the second layer, the work should be done 4 after applying the first.
- The lack of shine on the surface speaks of the complete drying of the primer.
Tree
To extend its service life, the tree needs to be primed. Because of its bactericidal composition, the primer keeps the material from rotting and also keeps bugs from growing.
- Wooden walls absorb the coating well.
- The composition is applied to at least two layers.
- Drying time is 12-20 hours at a temperature above 19 degrees.
Brick
Deep penetration compositions or universal primers are most frequently used for processing.
- Depending on the age of brickwork, the coating occurs in several layers.
- One layer dries in 4-5 hours.
- If a lime plaque is present on the wall, the polymerization period increases to 8-10 hours.
Plates OSB
A layer of paraffin protects OSB slabs during production. Remove everything before you apply the primer. If not, the composition won’t be absorbed, the paraffin will eventually vanish, and the plate won’t be useful.
- Most often, for processing the OSB, primers are chosen on an oil or synthetic basis.
- The plate does not swell with them, and its service life increases. Drying time is 24 hours.
Primer Type | Drying Time |
Deep Penetration | 4-6 hours |
Dispersion | 2-4 hours |
Alkyd | 12-24 hours |
Acrylic | 1-2 hours |
On Plaster | 4-6 hours |
On Putty | 2-4 hours |
It is essential to understand the drying times of various primer types in order to efficiently plan your painting project. Deep penetration primers typically dry in a day, though this can vary based on the surrounding temperature and humidity levels. These primers work wonders for priming porous surfaces and guaranteeing a good paint adhesion.
Dispersion primers usually dry much faster and are frequently used on walls and ceilings. They can take two to four hours to get ready for the next layer. A more efficient workflow is made possible by this short drying time, particularly for projects where time is of the essence.
Alkyd primers typically require more drying time because of their strong adhesion and durability. They should take between 12 and 24 hours. These primers provide a strong foundation for topcoats and extend the life of your paint job, making them perfect for use on metal and wood surfaces.
Acrylic primers dry relatively quickly—often in two to four hours—and are preferred for their adaptability and simplicity of use. They’re a well-liked option for many DIY enthusiasts and pros alike because they work well on a range of surfaces, including drywall and plaster.
The drying times of primer on plaster and putty can differ greatly. Primers can dry on plaster in a matter of hours, but putty, with its thicker consistency and higher moisture content, might take longer. Prior to starting, make sure the surface is totally dry to prevent problems with paint adhesion and finish quality.
In general, managing your painting projects more effectively is made possible by knowing how long various primers take to dry. You can guarantee a streamlined, effective workflow and a polished surface by scheduling these times.
