How to put a previously painted surface properly

Whether you’re preparing for a new project or just want to give a room a new look, revitalizing a previously painted surface can liven it up. Knowing the right procedures guarantees a flawless, long-lasting finish that looks fantastic. Let’s go over the necessary procedures to prepare your surface for a new coat of paint.

Start by giving everything a thorough cleaning. Grease, dust, and other debris can impede paint from adhering correctly. After cleaning the surface with water and a mild detergent, give it a thorough rinse. Let it air dry completely before proceeding to the following steps. The longevity and adherence of the paint are significantly improved by this easy step.

Next, look for any flaws in the surface. Check for holes, cracks, or paint that is peeling. Painting must be done after addressing these. After removing any loose paint with a scraper and using filler or spackle to patch any holes and cracks, sand the area smooth. This preliminary work guarantees a perfect finish, devoid of lumps and uneven areas.

It’s time to sand after the surface has been prepared and smoothed. To achieve a slightly rough texture, use fine-grit sandpaper to lightly sand the entire area. This improves the new paint’s adhesion. To get rid of all the dust, use a moist rag or tack cloth to clean the surface after sanding. In order for the new paint to adhere properly, the surface must be clean.

Apply a primer that is appropriate for the surface and kind of paint you are using last. Primer improves paint adhesion, hides lingering flaws, and can intensify the color of the paint. You can apply the paint of your choice after the primer has dried. For optimal results, adhere to the manufacturer’s instructions and relish your newly renovated area!

To achieve the best results, there are a few essential steps to take when preparing a previously painted surface for a fresh coat. To begin, give the surface a thorough cleaning to get rid of any loose paint, grease, and dirt. After that, sand the surface to give the fresh paint a uniform, smooth surface. Fill in cracks and holes to fix any imperfections, then sand the areas again to level the patches. Lastly, use a primer to ensure that the fresh paint clings properly and stops any previous paint colors from showing through. These instructions will assist you in getting a polished, long-lasting finish.

We examine the surface

There is no choice but to remove the old layer if the old colorful coating on the walls is really old and is starting to crumble, peel, and swell. However, the painted surface frequently appears to be quite acceptable, and then a faint hope to avoid laborious and unclean work emerges.

A small study must be conducted to ascertain which dye is applied to the walls in order to determine whether putty on the paint is feasible. Use a brush or sponge to moisten the surface area, then let it sit for 15 to 20 minutes. Consequently, one of the subsequent images is discernible:

• The paint foams and can be removed with a spatula without much hassle. This is a water-based composition that will have to be removed (although this is not difficult to do). If you putty on such a coating, it will simply draw moisture from the fresh layer, and it will soon begin to crumble.

• The coating has a durable glossy film that is not washed off with water. Is it oil paint or enamel. If the coating was applied with high quality, it is not easy to get rid of it, and, in the case of particularly strong adhesion to the wall, it is not necessary. True, before applying putty, the old layer is treated in a certain way.
• The water had no effect on the finish. Acrylic and latex paint demonstrates a high level of moisture resistance. If they are firmly on the surface of the walls or ceiling, cleaning may be a problem. Then you can putty on the walls with paint, but in damp rooms it is risky: the bottom layer may deform over time. In any case, the surface is clicked, cleaned and covered with a primer before applying the finish layer.

Check the strength of the painted layer further if it has not reacted with the water. To accomplish this, simply press along the wall with any metal tool, such as the same spatula, and draw. Should fissures emerge and the paint starts to peel off, it will need to be entirely removed.

How to remove the old layer

The simplest method for removing water-based paint is to rinse it off with water and let it dry completely on the surface. In other situations, they use one of the following techniques:

• Mechanical. The old paint is removed with a spatula; greatly facilitate the work and increase the productivity of a grinding machine. In any case, the method is considered time -consuming and dirty. If the paint cannot be completely cleaned, additional treatment with a primer solution (concrete contact) will be required to improve adhesion to the finishing material.
• Chemical. The coating is softened with a chemical reagent, then removed with a spatula. The product is applied with a roller or brush of medium thickness, work in a respirator; during work, the room needs good ventilation. It is difficult to get rid of paint this way, especially if there are several layers on the wall. In addition, using chemicals is always expensive.

• Thermal. The old coating is heated with a building hair dryer to a temperature of 500-600 °C. The paint begins to rise, form bubbles. The peeled off coating is removed with a spatula. The work requires caution: after heating, you must work carefully, use a respirator or mask, do not keep flammable liquids nearby.

Wall preparation: primer

It is not worth plastering over paint without first preparing the surface, even if the old layer is thought to be suitable to serve as the foundation for future decor. The walls’ surface is prepared as follows prior to puttying:?

• First, the wall is thoroughly sanded with sandpaper to get rid of remaining fragments of paint and varnish material.
• Remove dust and degrease the surface with an alkaline solution (a solution of laundry soap is suitable) using a sponge, then rinse with clean water.

If the substrate quality is the same across the wall’s surface, the finish will lie flat and last a long time; porosity is one such crucial property.

A primer is used to prepare the surface; it is preferable to buy a quartz primer that is specifically designed for this purpose. This building composition uses quartz sand as its primary filler material. An essential task carried out by the primer is to increase a base’s adhesion, regardless of quality. Because of the bactericidal components in the primer composition, it not only increases adhesion but also fortifies and sanitizes the base to prevent mold growth.

You can forgo the use of quartz primer if the building budget prohibits it. However, in this instance, there will be no other option for you to reach the required level of adhesion. The wall is covered in tiny, cross-shaped notches to give it more roughness. The result should be a grid effect, which takes a lot of time and effort to achieve. Any sharp tool can be used to make notches; a drill with a fine nozzle makes the job easier.

Putty

Puttying paint doesn’t cause issues as long as the preparation is done properly. After priming, the surface is first examined for quality after it has dried. Paint mesh for interior finishing work is used to level and reinforce the finish further if tiny cracks start to show. In this instance, carry out the following order of action:

• Apply a layer of putty to a dry wall using a wide spatula.
• While the layer is not dry, lay a painting mesh on top, helping yourself with a spatula.
• Apply a second layer of putty on top.

The layers’ combined thickness shouldn’t be more than 3 mm. In the event that paint mesh reinforcement is not utilized, putty should only be applied in two layers for intermediate drying. By using this method, any imperfections will be smoothed out and the wall will be ready for the main finishing work.

The surface is sanded following the application of the final putty layer. To attain flawless smoothness, this is done in well-lit areas because wallpaper or paint will draw attention to even the smallest flaw. In the final step, a thin layer of primer is applied to the wall and it is once more treated with fine-grained sandpaper. The wall is then prepared for finishing touches (like paint applied with a brush, roller, or spray gun).

Although preparing a previously painted surface for a new coat can seem difficult, following the right procedures makes it a simple process. To start, give the surface a thorough cleaning to get rid of any debris, oil, or dirt. By doing this, you can be sure the fresh paint will adhere correctly and last longer.

Next, look for any flaws in the surface, such as paint peeling or cracks. If necessary, smooth these areas with sandpaper and use an appropriate filler. In addition to smoothing the surface, sanding improves the grip of the freshly painted area, reducing the likelihood of peeling and chipping in the future.

Priming the surface is essential, particularly when painting over a glossy finish or making a big color change. A high-quality primer will improve the durability of your paint by providing a consistent base. To get the best results, use a primer that works with both the old and new paint.

Lastly, use even strokes to apply your new paint, paying attention to the manufacturer’s recommended drying times between coats. Since they provide a smoother finish and are less likely to drip and run, multiple thin layers are preferable to one thick coat. Your freshly painted surface will appear polished and new with patience and attention to detail.
