Plastering is not enough to achieve a perfect and smooth wall finish. It’s important to properly prepare the walls for painting after plastering. There are a few crucial steps in this preparation that will guarantee your paint sticks well and looks fantastic for many years to come. Let’s examine the essential steps you must do to prepare your walls for painting before you begin.
After plastering, the first thing to do is to let the plaster dry fully. Depending on your environment’s humidity levels and the plaster’s thickness, this could take a few days to several weeks. Here, patience is key because painting over wet plaster can cause peeling and other problems later on.
Sanding the walls comes next after the plaster dries. This process evens out any blemishes and produces a surface that is ready for painting. To remove any bumps or rough spots from the walls, use fine-grit sandpaper. To protect yourself from plaster dust, make sure you put on goggles and a dust mask.
It’s time to clean the walls after sanding. Paint adhesion issues can be caused by sanding dust and debris. Make sure all of the dust is gone from the surface by wiping it down with a damp cloth or sponge. Before proceeding to the following step, allow the walls to completely dry.
Painting the walls is a crucial stage that must not be disregarded. An excellent primer provides a stable base for paint by sealing the plaster. It also guarantees that your paint finish adheres correctly and helps to conceal any lingering flaws. Apply the primer uniformly, and as directed by the manufacturer, allow it to dry completely.
Your walls are now prepared for painting once the primer has dried. Carefully following these steps will produce a beautifully finished wall that improves the overall appearance of your room. A professional-quality paint job requires proper preparation, which makes all the difference in how your walls turn out in the end.

Classification of mixtures
Putty materials were categorized using a number of different criteria. Important elements and characteristics of putty, voluminous mixtures in the following classes dictate the group’s order:
- Oil-cell. If you need the cheapest mixture – the group is suitable. It is not known whether the prospect of oil solutions will be further, because they are already considered the past century. The main disadvantage is the manifestation of yellow spots through the paint layer and wallpaper.
- Gypsum -cement. Materials are an order of magnitude more expensive. Designed for a full set of finishing operations of a common orientation. In domestic products, most often, there are more cement than gypsum. On a cement and gypsum basis, the main purpose of the powder was determined for the masters – covering the layer of plaster with soil, you are likely to put down the wall with the composition of the wall for further gluing.
- Water-dispersion. Also from the category of gypsum -cement, however, they are necessarily produced with water polymer emulsion, respectively, containers – buckets. The advantage is that you do not need to study on the packaging, what to do and in what proportion to breed their putty – the products are already ready for use.
- Acrylic. After putty, such a composition will appear all the advantages of the aforementioned groups (except oil).
Stages of the work process
Surface cleaning
When the стен шпаклевка is produced after the старой штукатурки, the отжившие обои и слои краски необходимо удалить. Special washing is helpful in getting rid of any leftover unneeded material. The walls are left for approximately a day after manipulations to allow them to dry.
When the parts have dried completely, a mounting knife or thin spatula is used to clean any small pieces that were missed visually.
Inspection of the relief
Using a flashlight and the construction rule—applying it to the surface and letting the lantern shine along the wall—the embossed plane is examined. The tiniest voids and projections are readily apparent. Sharp spatulas or shirts should be used to remove rough bugs immediately, and a basic pencil should be used to mark the contours of the recesses.
Preparation of tools
Prior to beginning the repair procedure, the entire set of tools is carefully dust-wiped, dishwasher-washed, and dried with a thick cloth that removes fibers from the surfaces it has touched. It is important to pay close attention to whether there are any remnants of previous kneels’ solutions on a mixer from a drill and a kneading capacity—old solution lumps must be removed.
Preparation of putty mixture
The preparation of the solution is an easy process:
- A tank water is collected in the container (the construction bucket is filled by a quarter, the usual one is a third).
- Little a little fall asleep dry powder until the peak of the Iceberg is above the water.
- Expecting up to 30 seconds., until the powder absorbs water and does not go: there should not be dry formations.
- With a quick verified movement using a nozzle on a drill, a knead is made for 2 minutes. (the drill is preferable, however, it is also allowed).
- They expect 30-60 seconds..
- Repeated batch. The consistency is brought to the perfect – the solution is ready.
The final solution cannot ever be made any less concentrated by adding more water or dry powder. Will need to adapt to the circumstances. If there are any flaws, the putty is the extra fluid, and you can always use an abrasive to walk around the site and the house as needed.
It is advisable to knead a few servings of the finished solution in advance of its expiration date. The quantity required for a single smear is determined by placing each portion on a wide spatula in smaller increments.
Relief of relief
Depending on the size of the defect, small excavations and cracks are covered with a medium or wide spatula. The grout is applied to a smooth surface free of pickles and influx using broad cross-steam movements and equal effort.
A mistake that novice masters frequently make is to press and extend the spatula slowly. Any brand’s putty has a tixotropic quality, which causes an early proper dispersion and a periodic equal force effect from multiple directions.
The process of building the wall with your hands is shown in the video.
Flasping the putty layer
As with stucco hardening, all safety measures must be taken when hardening putty. For example, air flows, direct sunlight, thermal waves from a thermal talent, and hair dryers are all strictly prohibited. The wall’s drying-related cracks are already unsightly, but the putty layer was ruined by improper drying, which only showed up when gluing or painting was done.
To prevent drafts and sudden temperature changes, the air circulation in the room must be adjusted. To be more precise, you can open the door to the room but keep the balcony closed. To allow air to flow from living rooms into the corridor, close together the doors leading to the street, kitchen, and bathroom.
The majority of the time, the usage instructions specify that the coating can dry for up to 16 hours—more accurately, 10 to 12 hours. It is best to grind the layer no sooner than the next day, though, as this will help the putty dry out and solidify, making the work easier.
Putty for wallpaper
Using a wide spatula, apply putty to the wallpaper, blocking each subsequent layer up to ¼ of the previous layer in order to further adhere it. The "sausages" that are produced don’t rub. Maintaining a steady pressure while holding the spatula at an angle between 21 and 30 degrees will aid in distributing the material into a 2 to 4 mm homogeneous layer. A thick layer is more likely to form at a smaller angle of inclination than a thin one at a larger angle. On the other hand, reliance is a feature of changes in the designated degree gap; upon leaving its frames on the surface, tubercles and fractures appear.
The layer must then be dried, the fugan’s ingress must be eliminated with an abrasive, and the smoothness must be confirmed using the construction rule and a lantern. The ensuing flaws remove protrusions, which act as an abrasive, and excavations, which cause further smearing. An inexperienced master may approach the wall up to five times before the surface is flawless.
A fugan with a size of the size row is 80–120 at the conclusion of manipulations and a protracted solidification along the wall (as the number increases, the abrasive grain decreases). First, the entire surface is worked out in circular swings. Next, the contours of the circular manipulations are removed by weakening the grip with cross movements.
Next, the wall is once more confirmed using the lantern and the construction rule. If there are no leftovers from the rule, the surface is prepared, and you can begin gluing within a day after the walls’ primer is completed.
Putty with subsequent painting
The final step in the technological process is to apply finish plaster to the wall after it has been leveled and rubbed with an abrasive material. This is what sets it apart from putty. If the wall is painted with enamel, especially acrylic, great care is taken; the resulting mixture should be white, long-lasting, and made specifically for this use.
Grout is an abrasive that has at least 150 small grains.
To polish the wall for mirror painting, use a doted falcon made of suede material (felt and felt pieces are not suitable). The suede tightening method used previously will not be adequate for the task; a new method must be used. Additionally, the wall needs to be primed in accordance with the instructions on the material’s packaging before painting.

For your paintwork to have a smooth, polished finish, the walls must be properly prepared after plastering. By giving the surface a thorough cleaning, sanding, and priming, you can make sure that the last coat of paint sticks perfectly and looks great. Although the steps involved in this process may seem laborious, the end results are well worth the effort.
The first crucial step is to clean the walls. It’s crucial to wash the walls with a mild detergent solution and allow them to dry completely because debris such as dust, dirt, and grease can impede paint from adhering properly. Fine-grit sandpaper can be used to smooth out any remaining imperfections, helping to create an even surface for the primer and paint.
Another crucial step is priming the walls. A high-quality primer can conceal small flaws and seal the plaster in addition to giving the paint a consistent base. Primers increase the paint’s durability and help to bring out the color. Make sure the primer you select works with the kind of paint you intend to use.
You can begin painting the walls after they have been thoroughly cleaned, smoothed, and primed. In addition to ensuring a lovely finish, taking these preparatory steps prolongs the paint’s resistance to peeling and cracking. The overall look and longevity of your paintwork are greatly improved by spending time in preparation.
After plastering, there are a few crucial steps to take in order to ensure a smooth and long-lasting finish when painting walls. First, allow the plaster to dry completely; depending on the circumstances, this may take a few days. After lightly sanding the surface to smooth out any flaws, clear away any dust and debris. To seal the plaster and provide a consistent surface for painting, apply a primer. Lastly, before applying the topcoat, look for any minor flaws, fill them if needed, and sand again very lightly. This meticulous prepping method contributes to a long-lasting paint job that looks professional.
