Selecting the appropriate primer is an essential step in wall finishing, impacting the paint job’s durability and appearance. It is important to know how long different types of primers take to dry so that your walls turn out as good as possible. Every type of primer has different drying times and characteristics, whether you’re using an acrylic primer, a deep penetration primer, or a regular primer.
Acrylic primers are well-liked for their user-friendliness and quick drying times. They are a handy option for short projects because they typically dry to the touch in a few hours. Conversely, deep penetration primers take a little longer because they are made to seep into the wall surface for improved adhesion. The full drying time for these can be several hours. Ordinary primers may take about the same amount of time to dry as acrylics, but they may perform differently and require more coats.
You can better plan your project and produce a smoother, more polished finish by being aware of these details. This article will look at these primers’ drying times, talk about how many layers are usually needed, and highlight the qualities that make each type appropriate for various wall types.
Primer Type | Drying Time | Features | Number of Layers |
---|---|---|---|
Acrylic Primer | 30 minutes to 1 hour | Quick-drying, good adhesion, suitable for most surfaces | 1-2 layers |
Deep Penetration Primer | 1 to 2 hours | Penetrates deeply, ideal for porous surfaces | 1 layer |
Regular Primer | 1 to 3 hours | Standard drying time, good for general use | 1-2 layers |
The drying times and properties of regular, deep penetration, and acrylic primers can differ greatly when it comes to wall priming. While deep penetration primers are intended to seep into porous materials, they frequently take longer to dry than acrylic primers, which typically dry more quickly and are appropriate for a wider range of surfaces. Ordinary primers are in the middle, though they can vary based on how they are made. The quantity of layers required can also affect the effectiveness and duration of drying; more layers usually mean longer drying times. Recognizing these variations aids in selecting the appropriate primer and guarantees a glossy, long-lasting wall finish.

How long does primer dry on the wall
Navigating pages
A mixture of solvents, drying oil, and resins called primer is applied to the walls to get them ready for the next step.
Why apply primer to walls
For the following reasons, experts believe that the process of impregnation must be followed:
- The process enhances the strong adhesion of paint, wallpaper or other covering material to the base due to the penetration of the impregnating composition into the pores of the material and gluing of particles.
- Applying the primer evens out irregularities and roughness.
- The finishing material adheres better to a flat surface, the period between repairs lasts longer, which will reduce costs.
- Modern primers prevent the development of fungal formations.
How many layers are applied
Because plasterboard sheets are smooth and have an absorbent capacity that enables the impregnation to penetrate to a sufficient depth, it is sufficient to impregnate the board just once.
Experts advise applying two layers of primer before beginning any subsequent step, such as plastering, puttying, painting, or gluing tiles or wallpaper.
How much time does it take to dry?
Manufacturers list the duration under standard conditions on the packaging; however, the following factors should be considered as they affect the composition’s polymerization time:
- Thickness of the applied layer.
- Mixture solvent, acrylic dries within 3-4 hours, oil and contact require up to a day.
- Time depends on the condition of the material, dry and porous sets faster, recently plastered will require more time.
- Cyclizes faster at positive temperatures and dry air.
The drying time varies according to the type of primer:
- Acrylic requires at least 300 minutes after application.
- Alkyd requires 20 hours.
- Glyphthalic requires at least a day.
On a concrete wall
The primer that is used determines the minimum polymerization time.
- Acrylic on a concrete wall sets in 5-6 hours at room temperature and average humidity.
- Quartz, also called contact, dries in 60 minutes with one-time impregnation.
- Perchlorovinyl is used for concrete bases, polymerization occurs in 25-30 minutes.
The wall is dry and you can move on to the next step if it isn’t sticky or stains your hands.
On brick with plaster
When using an impregnating mixture on plaster composed of cement and sand, the process takes two to three hours; when lime is added, the time required doubles.
Brick-based acrylic mixtures take 5–6 hours to dry, while perchlorovinyl mixtures take 30 minutes. For plaster impregnation, concrete contact ones are utilized; polymerization takes up to 25 minutes.
On a concrete wall before plastering
When applied to concrete beneath the plastering stage, deep penetration impregnation at a temperature of 18 to 25 degrees and a normal humidity level will dry in 120 minutes; a water-based primer will take the same amount of time.
Atop wooden walls
Alkyd and oil impregnations are also utilized, as well as compositions with an alcohol base or drying oil that work well for wooden bases. To ensure the process is finished, add an additional 60 minutes to the time listed on the manufacturer’s packaging. On wood, acrylics dry in twenty-four hours. Alkyd mixtures at 23–25 degrees take about 30 minutes to dry on a wooden base.
Shellacs in alcohol-based solvents for wood finishing cure for thirty minutes on a wooden surface. When applying oils to wooden structures, a day should pass before moving on to the next step.
How long does deep penetration primer dry on a wall
Deep penetration primers, which are used to strengthen and lessen the ability of weak surfaces to absorb moisture, contain acrylic compounds.
You will need to let the acrylic mixture dry for the entire night.
Depending on how many layers there are, concrete contact ones can take one to six hours to dry.
When can you paint, glue and putty
Although the primer layer adheres to the putty well and dries rapidly, experts advise waiting until the putty is completely dry to avoid wrinkles or bubbles in the wallpaper. Putty can be started before the plaster dries completely. The impregnating mixture sets in 2-3 hours on cement-sand plaster and 4-6 hours on cement-lime plaster. It’s important to keep in mind
- Primed putty walls should be painted after complete polymerization.
- Painting with old paint is done after the mixture has polymerized, in this case the old paint will not peel off.
- Painting on plaster without putty requires covering with a primer composition in at least two layers, and each layer is applied to the completely dry previous one; it will take at least a quarter of a day to be completely ready for painting.
Popular types of universal soils
Experts select a particular impregnation mixture for a particular kind of work; for a novice, it is preferable to use a universal primer that is appropriate for fixing the premises in order to avoid mistakes or when working with different materials.
The following types of universal impregnations are distinguished based on their composition and are utilized for a variety of materials:
- Universal acrylic.
- Deep universal primer.
- Universal latex.
The following are the top ten deep penetration primer mixtures:
- "Starateli".
- "Ceresit".
- "Optimist".
- "Bolars".
- "Tex".
- "Knauf".
- "Lakra".
- "LAES".
- "GLIMS".
- "AXTON".
Primers are used as auxiliary materials in construction and repair; however, their application to the room’s surfaces depends on technology, which affects the quality and longevity of the repairs made as well as how long it takes between repairs.
Experts strongly advise performing the impregnation step twice during repair work in accordance with technology, as only a small amount of composition is required for repairs.
It is essential to comprehend the drying durations and application guidelines of various primers in order to attain a flawless and long-lasting wall finish. Acrylic primers are a good option if you want to finish your project quickly because they usually dry faster than deep penetration or ordinary primers. Nonetheless, every variety offers unique benefits and is appropriate for distinct uses.
Deep penetration primers are perfect for porous surfaces because they have good adhesion, but they might take longer to dry completely. Regular primers, on the other hand, give paint a good foundation, but for best results, they may require additional layers. The total drying time can also be affected by the number of layers you apply; in general, applying more layers lengthens the drying time.
You can guarantee a long-lasting, polished finish by selecting the appropriate primer and applying it properly. To achieve the best results for your wall finishing project, make sure you adhere to the manufacturer’s instructions regarding drying times and layering.
