It’s easy to want to get started on wall finishing projects right away after puttying is finished. Ultimately, the walls appear polished and prepared for the following phase. Priming the walls is a crucial step that you shouldn’t omit, though.
Although priming may appear like an extra step, it is essential to achieving a perfect finish. It improves the paint’s or wallpaper’s surface adhesion, averting later problems like peeling or uneven application. It essentially serves as a link between the final layer and the puttied surface.
Ignoring the primer can result in a number of issues that could damage the appearance of your walls and require additional work down the road. Therefore, make sure to apply a coat of primer before continuing with painting or wallpapering. A tiny amount of work can have a significant impact on the durability and quality of your wall finish.

Properties and purposes of using primers
You must be aware of a primer’s characteristics and function, including its capacity to affect the base and the applied coating, in order to comprehend the necessity of primers in the finishing of walls or ceilings.
If you give the task to a dependable master, you won’t need to comprehend every aspect of the subject. In addition to saving time and energy, this will ensure that the work is completed effectively.
Main properties
The composition, impact on materials, and range of application of primers can vary (refer to Types of Construction Primer and Their Scope of Application). The usage of this or that composition and its intended purpose are made clearer by the instructions provided on the packaging.
Yet a list of characteristics that are present in every primer is as follows:
- Ability to increase the adhesion of materials to each other. This property is called adhesion. The higher it is, the better any finishing layer will adhere to the base treated with a primer. In other words, with the help of this product we can significantly improve the quality and reliability of the finish.
- The ability to fill pores and small cracks on the surface. Getting into them, the components of the primer polymerize during drying, preventing moisture from penetrating into the structure of the material and protecting it from destruction;
- The ability to create a thin film on the surface. Thanks to it, the suction properties of the base are reduced, and the subsequent finishing layer lies evenly, and its consumption of materials for its creation is reduced. In addition, this film removes dust and strengthens the surface, binding its particles together, preventing them from crumbling.
Additional and auxiliary properties
Price is not the only factor that influences primer selection. Prior to applying it, consideration is given to the base material and the environment in which the repaired structure will be situated. Based on these considerations, a primer possessing specific characteristics is chosen.
- Concrete walls, as well as those covered with oil paint or walls lined with ceramic tiles, have a very smooth surface on which plaster or putty does not adhere well. They are treated with a special primer with the addition of particles of quartz sand or another abrasive, which gives the walls a roughness.
- Before painting, metal surfaces are covered with a primer with anti-corrosion properties that prevent rust.
- For wooden structures, it is recommended to use a primer with additives that make them resistant to fire and harmful insects (see. Primer for wood and the rules for choosing it).
- If the room is poorly heated, exposed to water vapor and other negative influences, it is reasonable to use a primer with antibacterial properties to prevent the occurrence and growth of mold.
Finishing material type is also important. Applying acrylic paint-primer to the walls before painting with acrylic and water-based compositions makes sense.
Under the wallpaper, you can apply liquid-diluted wallpaper adhesive. Additionally, drying oil is the best treatment for wooden bases used with oil paint.
To save money on pricey decorative paint and give the base the desired shade, the primer-paint can be chosen based on color.
In other words, the primer has certain properties due to the presence of certain additives, which should be considered when selecting.
Suggestions. Additives and auxiliary ingredients raise the product’s price. Purchase only the properties you require in a primer to avoid going over budget.
At what stages is priming necessary
Let’s examine the wall finishing process in its entirety to determine when priming is necessary. Plaster, primer, and putty are done in a standard order.
But is one primer layer sufficient to sit between two layers of leveling? Or will more be needed?
- If you have a new concrete or brick wall in front of you that needs to be plastered, treating it with a primer will strengthen the surface, enhance its adhesion to the plaster mortar, and, if necessary, protect it from mold.
- If you are about to renovate a secondary home with preliminary cleaning of the walls from old peeling plaster, after this procedure you also need to prime the surface to strengthen it and level its absorbent properties.
- Dried plaster mortar, due to its high sand content, forms a rather loose surface with particles that crumble under mechanical action and a low level of moisture resistance. Picking it with a primer, in addition to increasing adhesion, allows you to eliminate these shortcomings: turn the plaster into a strong monolithic moisture -resistant plate.
This is of great importance! Only after the solution has dried to the full thickness can pinch surfaces be primed. It could take a few days or a few weeks to complete.
- An important question: how long after the primer you can put up the walls? By technology, this is done after the surface absorbs the composition and dries. But you should not allow the settlement of dust, fat and oily substances on it. Therefore, a primer, for drying out on average 2-4 hours, is applied after cleaning the room and shortly before putty.
- If you putty the walls after removing wallpaper or other coatings, without knocking off the old plaster, the primer is again required even if it was used during the previous renovation. It will make the surface more durable and close all possible household spots on it with an impenetrable film, which can appear through new wallpaper or paint. Rule, after how much you can putty after the primer, remains the same.
Be mindful. No matter how many layers are applied, it is advised to use soil to achieve the highest level of plaster and putty reliability. An exemption may be granted for materials that belong to the same brand and composition, such as plaster, primer, starting, and finish putty from the same manufacturer’s line. Only the base, final plaster layer, and finish layers are primed in this instance.
- The last layer of soil is applied to the finally leveled walls before their decorative trim. It will save on a wallpaper and paint that will not be absorbed into the putty, so their consumption will be below. Rust, oil and other stains that are under the leveling layer or on it will not show through the decorative coating. And during the next renovation, it will be easier for you to remove the damaged coating from the walls without damaging the integrity of the base.
A moist sponge should be used to remove any dust from the wall before final finishing if a significant amount of time has elapsed since priming.
Do you need to prime the walls after puttying? | Yes, it"s essential to prime the walls after puttying to ensure better adhesion of paint or wallpaper. |
Why prime before painting? | Priming before painting seals the surface, reduces absorbency, and helps the final coat adhere better, leading to a smoother finish. |
Following puttying, priming walls is a crucial step that shouldn’t be overlooked. It guarantees that the surface is adequately sealed, avoiding uneven paint absorption. This makes the paint last longer and produces a smoother finish.
Additionally, priming makes the putty and paint more bonded, which lessens the likelihood of peeling or cracking over time. It’s a simple step that has a significant impact on your walls’ longevity and aesthetic appeal.
You’re laying the groundwork for a polished finish that will last for years by taking the time to prime your walls. Although it’s a straightforward procedure, it greatly raises the standard of your wall finish.
It is important to prime walls after puttying in order to ensure better adhesion and an even finish when painting or wallpapering. Ignoring this step can result in problems like uneven paint soaking or peeling wallpaper, which will eventually affect the longevity and aesthetics of your walls.
