How to match the color
Since the natural color of water-based paint is white, and if it needs to be given the desired color, then you can use one of two methods, this is with the help of a special apparatus or dilute it with your own hands. The first method implies that in many points of sale of paints and varnishes, there is a free service for the service of coloring paints. All you need to do is buy paint from them and choose the desired color or shade, paying extra for the coloring pigment.
In the case of the second option, then you will have to purchase jars of coloring pigment yourself and dilute it with your own hands using a construction mixer. At home, this is done in this order, in a small container the color is diluted with water-based paint, and then, the resulting composition is gradually added to the main bucket of paint, thoroughly mixing with an electric drill with a mixing nozzle until the desired color consistency.
A little tip: Before proceeding directly to the painting itself, apply a test water-based paint to an inconspicuous small section of the wall, since the color of the paint in liquid form has a brighter shade than in dry form. Please note, prepare the paint in such an amount that it is enough to paint the entire area of the room, since in the future, it will be much more difficult to achieve the desired shade.
Preparation
Despite the fact that painting drywall is not a difficult process, you cannot call it easy either. The color should be even so that no bumps, pits and other similar flaws are noticeable.
By the way, on our website you can study a video that will tell you how to paint drywall correctly.
Unfortunately, filling the seams is not always good enough. And they especially face difficulties with a multi-tiered structure. It is best to take an oily putty for this, since it will stick just fine on cardboard. In addition, it will rub over and not scrape off.
Preparation stages
Before painting the drywall walls, we putty the seams.
Particular attention should be paid to the places that formed after screwing in or hammering in the fasteners.
We are waiting for everything to dry. It is better not to rush here and wait a day.
Apply a leveling layer with a wide spatula
We need to get a uniform texture that will remind us of paper.
If you finished the putty, it would be nice to walk with a primer. Otherwise, the cardboard may bend and absorb moisture from the mixture.
And only then can paint be applied. If you do not know how to paint drywall, then the following tips are for you.
Choosing paint
Despite the fact that this process, it would seem, is not complicated, but it also has many stages.
In general, you can talk a lot on this topic, but we will consider the basic rules on how to paint drywall correctly, which should be followed when choosing a paint.
- After the seams of the cardboard have dried, apply glue or putty;
- Do not use glossy paints, as they reflect light very strongly and all defects can be seen. Use only matte;
- Light colors will help hide defects.
How to properly paint a plasterboard ceiling
The use of washable water-based paint is not rational in all rooms. For example, for painting a plasterboard ceiling in the kitchen, this paint is an excellent option. For molar work in the bedroom - a waste of money. Rollers with natural pile show themselves well in the work.Unlike synthetic ones, they absorb paint well, do not leave streaks and marks. Naturally, the price of rollers with natural pile will be higher than synthetic ones, but the overpayment is worth it. To avoid rolls, according to the instructions, the paint is diluted with water. If the work area is hot, it will not hurt to add a little more water than usual, which will help the paint dry slowly. The installation of the plasterboard ceiling and the plastering work have been completed. The walls have been brought to perfection.
It remains to choose a paint, a tool and start painting work. How to paint a plasterboard ceiling to make it look perfect and without streaks will be discussed in this article. Cheap paints lay down in an uneven layer and dry quickly, which, when reapplied, leads to the appearance of ripples. Quality paint behaves differently. The applied first coat of paint on drywall does not dry so quickly.
The second layer mixes perfectly with the not completely dry first, forming a homogeneous mass, without streaks and streaks. The durability and appearance of the gypsum plasterboard ceiling surface after paint application depends on the adherence to the painting technology at each stage of the repair work, including the implementation of preliminary measures. After finishing the processing of the seams and gluing the serpyanka, they begin to putty the gypsum board. There are several finishing methods. The most economical of these consists in laying one layer of putty mortar, grouting and applying a finishing coat.
Semi-glossy. This option is best for kitchens or bathrooms with high levels of moisture and dirt. Moderate gloss will hide flaws in the finish, cleaning the surface will not take much time. Tools for painting the ceiling can be roughly divided into basic “working and auxiliary. The first include those that directly carry out the whole process: After priming, you need to carefully seal all the seams on the ceiling surface from the gypsum board.
If this is done poorly, your painted ceiling will very quickly be covered with a whole network of small cracks. To seal the seams, use a special putty, which is intended specifically for processing drywall. Which one should you use?
There is no consensus here. Dispersion compositions during long-term operation well retain their high moisture resistance and initial appearance. But they are produced mainly in white and its various shades.
- Water-based paint for plasterboard ceilings.
- Acrylic primer for deep penetration.
- Color for water-based coating. A different palette of shades allows the ceiling to be painted in any color, and the interior will acquire originality and individuality.
- Small pile fur roller.
If, nevertheless, the question arises, what is the best way to paint the plasterboard ceiling, then you can always go to the nearest building supermarket and seek advice from the manager. Indeed, even in the segment of water-based coatings, you can find several options from different manufacturers. And the result will directly depend on their choice.
Creating a textured surface
The textured surface design is created using undiluted material. The process of applying the composition is so that the wall does not look smooth, but has interesting roughness.
The primary finish is applied with a nap roller, while the material must be viscous and thick - this is how all the pores of the surface are filled. The second coat should be applied with a lint-free tool, and a sponge is used for the topcoat. For the surface to be embossed or patterned, the finish may have a different shade.
Creation of texture by means of a coloring composition
You can also create a textured wall with a coloring composition. To do this, you do not need to strive to level the walls to absolute smoothness.If the walls were plastered and primed, then instead of the plaster layer, the coloring material is immediately applied. In this case, the rolled surface can have pores, depressions and dents, which will be filled with paint.
In addition to the composition itself, to create a textured wall, rollers with a special nap are used - attached flaps, cutouts, a spongy surface. However, this consumes more material for painting.
Preparation for work
The preliminary stage before painting involves preparing the base for applying a decorative and protective layer. Thanks to careful preparation, the staining procedure will be easier, and the final coating will last longer. The procedure before whitewashing is as follows:
- The area for processing is carefully inspected, the remains of the previous whitewash, drips, traces of old paint, etc. are revealed. If the tool allows, it is better to clean the base completely (down to a concrete slab, for example).
- You can remove the old paint layer with a brush or metal scraper. Wetting the ceiling with water will help speed up the process. The wetted layer must be kept for 10-20 minutes. Depending on the thickness of the previous layer, the number of passes for preparing the base varies.
- Pasted wallpaper is easier to remove if it is wet beforehand. After a 20-minute pause, the cleansing procedure is continued. You can pick up firmly glued wallpaper with a spatula or scraper.
- In the case when the ceiling has already been treated with water-based paint, it will be difficult to soak the old layer. Mechanical cleaning is one way to get rid of old coatings. Chemicals are also used to peel old paintwork material. The toxicity of the means used involves the use of protective equipment (respirator, gloves), removal of residents from the room, and thorough ventilation.
- The crumbling plaster must be completely removed. In some cases, the preparatory stage is delayed, but the foundation must be brought to mind. Otherwise, the whitewash will not bring the desired effect, and the ceiling will look ugly.
Ceiling preparation involves removing existing stains. The removal method depends on the nature of the detected stain. If it is a greasy stain, then a rag soaked in an aqueous solution of soda (5%) is used. A wet cloth is applied to the stain until it disappears completely, the rest of the solution is subsequently washed off with plain water. Mold can be easily removed with diluted whiteness. After wetting the contaminated area, you need to wait for it to dry, and then remove the traces of mold with a sponge or a piece of rag. Traces of rust are removed with an aqueous solution of copper sulfate, and they are also hidden with a white oil coloring composition. Aligning painted ceilings is another mandatory step before painting with water-based emulsion. An even base will allow the ink layer to lie evenly. Sometimes the floor slabs are laid with a drop, and the seams between them are roughly sealed with cement mortar. In this case, you will have to hold the ceiling screed. The work involves the following steps:
How to properly prime
The priming process can be divided into preparatory and main stages:
During preparation, it is necessary to grind the surface, remove dust, dirt, mold from it. If necessary, dictated by the instructions for the primer-composition, the wall must be degreased: for this, acetone or similar solvents are used
During the preparatory work, it is important to observe proper ventilation of the room and the temperature regime within the range of 5-25 ° C.
The main stage of priming is to dilute the required amount of the composition and apply it to the walls.
How many times
The primer is usually applied in two layers, the first of which is thicker, and the second is necessary to better strengthen the surface.
At the same time, it is important to dry each layer of the primer for the time recommended on the package (usually several hours)
How to primer
Depending on the porosity, the walls can be primed with a brush or roller.
Each method has its own advantages.
The brush allows you to work on unplastered surfaces, while the roller gives a uniform layer without smudges, on which less soil is consumed.
How long can you paint
The minimum drying time for the primer must be found in the instructions for the specific composition, it usually ranges from 4 hours.
If repair work allows, then it will not be superfluous to let the primer soak for a day.
In addition, if the primer-composition was applied to plaster or putty, then the subsequent painting should be carried out only after all layers of the finish have completely dried.
The drying of the primer can be slowed down by open containers filled with water in the room, so it is better to remove buckets of water, remnants of diluted soil and other liquids from the room.
Do I need to prime before painting
The primer can be carried out with different compositions: paint, ready-made primer or concentrate, which is diluted according to the instructions. Also, solutions are marked relative to the surface to which they will be applied (wood, metal, plaster).
Water-based
Water emulsion is not the cheapest finishing material, therefore, preliminary priming of the walls will significantly save on paint consumption.
The primer applied under the water-based paint reduces the hygroscopicity of the base, which leads to a more even distribution of the paint on the surface, strengthening the coating, and increasing the wear period.
The primer under the water emulsion is applied with a brush, preferably in one layer, which should ideally cover all the unevenness of the wall, but at the same time not form uneven accumulations of soil. After complete drying of the primer-composition, which takes 5-7 hours, the water-based paint is applied in two layers.
Silicate
Silicate paints are sold dry; for coloring, the mixture must be diluted with water and used as soon as possible, until the paint has lost its properties. Therefore, a pre-primer on a silicate base is of great importance for the speed and quality of painting.
Special primers reduce the toxicity of the alkali contained in silicate paints and strengthen mineral surfaces to extend the life of the paint up to 10-15 years.
Acrylic
Priming before acrylic painting has an important feature: the composition must be applied to highly abrasive surfaces, from smooth surfaces it will gradually creep even together with the paint.
Therefore, before applying the primer, the surface of the wall must be treated with a stiff brush or coarse sandpaper in order to artificially create grooves and roughness.
In turn, the primer solution perfectly fixes the particles of the coating, leveling the adhesion and absorbency of the wall, which allows the acrylic paint to lie in an even and durable layer.
Oil
Oil paint is one of the most highly adhesive, even without a pre-primer coat. Priming increases the strength of the oil coating, making it smoother and less porous. However, often oil paint, applied without a primer-composition, itself acts as an unsurpassed material for finishing work, as it adheres well to the surface.
When applying oil paint for the first time, the use of a primer solution is not necessary. In the case of secondary, it is worth making a choice in favor of a special composition "over paint", which will save the time required to remove the old layer.
Application of water emulsion for painting the oven
The category of water-based paints includes all water-based paints with a mineral pigment filler and a small amount of organic liquid binders from acrylic, methacrylic and vinyl polymers.
Water-based paint composition with equal success can be used to paint both metal and plastic, glass, brick, plaster and concrete. Most often, water-based paints based on acrylic and modified synthetic rubber are used for interior work. Vinyl fillers are less commonly used because of their poor resistance to elevated temperatures.
Features of the use of water-based compositions
To be precise, modern water-based materials are not far from the classic lime and chalk solutions for whitewashing hot surfaces. But there are still differences:
- The presence of a polymer binder in the paint, even in a relatively small amount, increases the adhesion to the base of the oven surface by an order of magnitude. Thanks to this, the oven can be painted with a relatively liquid paint, without the risk of streaks or smudges;
- The use of surfactants and stabilizers of the mixture provides a low coefficient of surface tension, as a result, the water-based solution penetrates deeply into the pores of the surface;
- High resistance to oxidation and heat.
The smell of water-based paint differs in nature from the smell of a solvent of alkyd or even silicon organic enamels. Alkyd masses harden due to the volatilization of the solvent, without changing the polymer base. Cured paint can be reheated and easily removed from the substrate.
If you paint the stove with water-based paint, then the water-polymer base will intensively absorb oxygen from the air, oxidize and pass into an insoluble state. The stronger the heating, the faster the cementation process goes, the sharper the smell, which is absolutely harmless and quickly evaporates.
How to properly paint the oven with water-based paint
The dried layer of water-based paint is a porous, durable and at the same time elastic surface. Conventional water-based paints for interior use do not contain stabilizers or substances that prevent the aging and deep oxidation of acrylic or vinyl under the influence of heat and light. Therefore, exterior paints are used to paint the stoves.
The pore sizes allow air and water vapor to pass well, and when the furnace is overheated, the so-called "overheating", the polymer matrix of the water-based mass becomes similar to a terracotta surface. If possible, paint the oven surface again without compromising the strength of the paint layer.
If the walls of the furnace have already been covered with any varnish or paint, then before starting work, it is necessary to remove the gloss and sand the remaining layer of paint and varnish material. Ideally, it is best to paint clean walls. Sometimes the stove is painted with a layer of lime or chalk mortar. Both options, lime and chalk, must be removed, otherwise it will not be possible to paint the stove over the whitewash.
How to paint on whitewash
But since we all want to keep up with the times, and prefer painted surfaces, the question becomes: is it possible to paint on whitewash? How and with what to do it? You can immediately answer that yes, but there are some nuances. Let's consider them in more detail.
Is it possible to paint on whitewash
Although it is undesirable to paint, it is possible. And only in those cases if:
- There is a very thin layer of whitewash,
- It holds well, does not crack or crumble.
Otherwise, when painting, it will be removed with a roller. And as a result, we get a poorly painted and unaesthetic surface.
How to paint on whitewash
Before applying the paint, the surface is covered with a deep penetration primer. Then, it is given time to dry completely.And then they carry out a test for the appropriateness of staining by scratching the surface. If it is easily destructible and removable, then it is better not to risk it and not paint it. In this case, you cannot do without completely cleaning the surface from chalk. Well, if the primed surface has passed the test, then you can safely proceed to staining.
Whitewash water-based paint
If water-based paint is chosen as the paint for painting the surface, then you can do without a primer. This type of paint will act as a primer itself, binding and securely fixing the chalk particles.
If the layer of chalk or lime is thin, adheres firmly and does not have swelling and cracks, then the water-based paint applied to it will last for many years.
In what cases is it better not to paint the ceiling and walls with whitewash
It is strongly not recommended to paint on chalk or lime if:
- There is a thick layer of whitewash with cracks and swollen areas,
- If you plan to apply oil paint or enamel.
In order not to risk and ultimately not get a bad result, it is better not to save time and effort, but to immediately remove the layer of chalk or lime. Then the result will be much better and will last for many years.
How to paint a whitewash. Methods for preparing a ceiling or walls for paint application
If it is not possible to paint the ceiling or walls with the old coating, then it is necessary to clean it off. This can be done depending on the thickness, applied layer and quality.
But in any case, the first step is to take care of all the furniture in the room. It must be closed with foil and tape to avoid damage.
A small layer can be removed with a fleecy roller. It needs to be wetted and the ceiling should be cleaned, rinsing periodically. You can also use a brush for these purposes.
If the layer is thick, but does not hold very well, then it can be removed with a spatula, after wetting it. Then it is necessary to putty all the cracks and level the surface. And only then you can grind and prime it, preparing for paint application.
Well, and the last case: the lime was applied in a thin layer that adheres well. This happens most often if glue was added to the solution for strength and must be removed with a grinder.
It is imperative to prime the surface before applying paint. To do this, you can use a special primer, drying oil or wallpaper glue. The choice should be made depending on the paint that will be applied later.
