An iron door is usually installed at the entrance to the apartment. Wooden doors are rarely used due to their low strength. It is usually chosen for private homes. In any case, the question arises of how and with what to decorate the canvas on the inside so that the apartment or house is cozy and beautiful. There are different ways to refine the surface of a door block. But we must take into account that finishing the front door from the inside has its own nuances and features. You need to know about them so that the work is successful and the desired result is obtained.
Instructions for painting a metal door with your own hands
When starting painting, you need to follow the appropriate rules, otherwise the result will not be durable and you will soon have to repaint the door.
How to paint a metal entrance door
When you start work, remove all removable fittings (handles, peephole, number) and decorative elements. And cover those parts that cannot be removed with masking tape. It is best to remove the door itself and paint it in a horizontal position. To avoid staining the surface, place an oilcloth under it. Painting should start from top to bottom. This will help avoid leaks.
The next stage is surface preparation. If it was previously painted, remove the old layer. To do this, use a special remover that will dissolve the paint layer, a metal brush, or you can use a sanding machine. Apply a degreasing primer over the entire surface. However, if rust appears, it should also be carefully removed with sandpaper, a brush or acid. If there are any uneven spots or dents, smooth them out using automotive putty.
Preparatory work is needed to obtain the necessary adhesion of the metal to the paint, as well as for greater durability of the coating. If this is not done, the coating will quickly lose its protective properties, as a result of which the metal will be susceptible to damage.
Coloring rules
After preparation, you can start painting. The easiest way to paint is with a spray gun, but you can use a brush or roller. First paint over the horizontal parts and small details, and only then proceed to the vertical surface. Make sure that the layer is of uniform thickness.
Varnish or paint is applied to a metal surface in several layers. But the previous layer must dry well. At the same time, make sure that the color tone is uniform and there are no transitions or gaps.

When choosing a coating for a metal entrance door in a private home, pay attention to its durability and wear resistance. Hammer and powder coatings or alkyd enamel are best.
Review of paint and varnish compositions for metal
The modern market offers a wide range of compositions for painting metal surfaces. In addition to the entrance to the premises, doors to utility and utility rooms are installed in a private house. Depending on the purpose, surfaces can be painted with different compositions. The logical conclusion of an apartment renovation is updating the front door. It is the “calling card” of the house.
Names of colors for painting metal doors
In this case, enamels are used, which not only protect the canvas and the box, but also give the canvas an attractive appearance. For utility room doors, the emphasis is on the protective properties of the coloring material. The peculiarity of the entrance metal group is that the canvases operate in two modes, outdoors and indoors, so the coating must withstand a fairly large range of temperature changes. An important point is the resistance of the coating to mechanical stress and abrasion.
Types of paints and varnishes
The application of a protective coating depends on the purpose of the metal door.
For utility rooms, you can use more affordable enamels. For the main door, compositions are chosen that can update its appearance. Since paint consumption is small, more expensive, reliable compositions with a decorative effect can be used.
In total, paint and varnish products can be divided into:
- Powder paints that are diluted with solvents.
- Water-based paints using pigments and fillers.
- Enamels whose ingredients are mixed with solvents. This category includes paints based on cellulose nitrate (nitro-enamel) and acrylic compositions, which include polymers (acrylic, latex), alcohol-containing ingredients and acids.
Alkyd paints have a low threshold for high temperatures (80⁰C), and they have a characteristic pungent odor. Acrylic, from an environmental point of view, is safer, they are resistant to high temperatures (120⁰C), and there is no pungent odor.
Alkyd paint for painting metal doors
There are also two-component compositions based on epoxy resins and polyurethane compositions. Mix immediately before use. They are more used for painting technical rooms with high humidity and thermal loads.
To paint metal doors, mainly water-based enamels or those containing solvents are used. It is not recommended to paint iron doors with conventional oil-based paints, despite their affordable cost, due to their fragility.
Packaging and packaging form of paint and varnish products:
- powder formulations, for example, silver;
- packaged in tin cans, plastic buckets;
- are produced in the form of aerosols (cans with a spray).
Nitropaint
Nitro paint is often used to paint steel entrance metal doors. Nitrocellulose enamels have a number of advantages: a wide range of colors, do not dry for long, low price. Immediately after coating, the metal surface has a beautiful glossy finish, but over time the color will fade. Although nitro paint protects the metal from corrosion, it does not last long and is not resistant to external factors.
Be careful when using nitro paint, because it can only be used in a non-residential, well-ventilated area, or better yet, outdoors. The toxicity of the coating will persist until it dries completely.
Using hammer paint
The metal surface, coated with hammer paint, has an unusual and original appearance with a hammer effect. The roughness of the coating makes it possible to hide minor flaws in metal products.
To paint a metal entrance door with a hammer coating, no special surface preparation is required. The paint has excellent adhesion to metal. If applied correctly, it can last up to 25 years. In addition, due to its durability, protection of metal from corrosion, and comparative ease of use, it is gaining increasing popularity all over the world.
Wood painting
Painting a metal entrance door to match a wood structure requires a special approach. First, you will need to choose a special grater that will help imitate wood. Then paint in two shades: light and dark to imitate the type of wood.
After preparing the metal coating, you can begin painting. Start by applying a light shade. After complete drying, lightly sand, then apply coatings of a darker shade. Without waiting for it to dry, you need to carefully go over it with a rubber float, repeating the pattern of the tree. This will remove some of the dark tone, and the resulting pattern will resemble wood. When the second layer has dried, you need to coat the metal with varnish.
Features of powder paint
Powder coating doors has a number of advantages:
- fire safety;
- high resistance to damage;
- high environmental safety;
- attractive appearance.
However, the cost of such a coating is quite high, and it is impossible to apply it at home. The powder is sprayed electrostatically and heated in special chambers with a temperature of 200°C. This is how the powder penetrates the metal structure. After cooling, apply varnish.
Entrance doors are subject to heavy loads due to frequent use and exposure to external factors. Protecting an apartment or house from uninvited guests, entrance doors are subject to mechanical damage, fading in the sun, loss of brightness from moisture and other reasons.
The most popular methods for decorating the front door from the inside
When decorating the interior, designers recommend that customers use the following technologies for finishing the inner surface of the front door:
- Coating a steel sheet, plywood or OSB with a paint and varnish composition in a single color scheme, or with a shagreen effect. Most often, manufacturers use the principle of hammer painting with special pigment substances for metal, as they increase the corrosion resistance of the material and give a decent appearance to the surface.
Plywood door covering
- Upholstery of the inside of the door with leather or substitutes for natural materials with padding of the internal space with elastic inserts, for example, batting. This finishing option significantly increases the heat transfer resistance of the enclosing structure.
Carriage tie
- Interior cladding made of rigid panels - MDF, chipboard, plywood with textured color lamination. Materials can be combined with various inserts, including mirrors and steel overlays, which is especially important for high-tech interiors.
Door with MDF panel
- In many hardware stores you can find polymer stickers that are fixed to the smooth and grease-free surface of the door, creating the illusion of a beautiful landscape and other interesting images.
Stickers on the front door
When finishing an exclusive interior, designers also often personally decorate the front door, resorting to the technique of aging wood, brushing or decoupage. As a result of many hours of work, the result is an interesting vintage interior, or a pronounced “country” style.
Application of brushing technology
Can I paint or repaint the inside and outside myself?
Entrance doors in a house or country house lose their attractiveness over time, both inside and outside, so they need to be updated. The most popular for the interior and exterior of metal and other doors are classic primer-enamel and hammer paint.
The main thing is to follow safety precautions when painting - use protective equipment to prevent chemicals from getting on the skin, and keep children and animals away.
Tip: The most even coating can be achieved using a spray gun. If you don't have one, regular brushes and rollers will do.
Furniture polish
A high-quality furniture polish will help hide small scratches and disguise minor damage.
The polish gives the surface additional shine, while at the same time cleaning it from dirt. Most polishes contain silicone or wax. Before treatment, the door is washed or wiped with a dry cloth, after which the product is applied and thoroughly rubbed over the damaged area.
Removing scratches from interior doors with your own hands requires patience and accuracy. You can use both home and professional products, but you will have to act gradually and methodically: first clean the coating from dirt, apply a layer of the product, let it dry, spread it again, remove the residue, polish. Sometimes you have to use several methods at the same time, combining both folk remedies and professional compounds, but as a result the door will look like new.
What kind of paint should I use: hammer paint or another?
In order for the door leaf to look beautiful for a long time, you need to know how to choose the right paint. Main methods:
- Acrylic paint. Advantages: durability, quick drying. This material is non-toxic because it is water-based.
- Automotive paint , which is best applied with a spray or aerosol can. This painting looks expensive and stylish.
- Nitroenamel. It looks good, gives the product shine, and protects against corrosion. The downside is that the material is sensitive to chemical and thermal effects and will last a relatively short time, so it is better to use nitro enamel when you need to save money.
- Alkyd enamel. Whatever color an iron or other door is painted, thanks to the alkyd resins in its composition, the enamel does not lose it, and also dries quickly and retains its properties for 4 years. However, such enamel is not repairable. To give the canvas its original appearance, you will have to completely remove the old material, then paint it again.
- Hammer. Mainly applicable for armored door blocks. It can give the surface roughness and achieve a tone similar to the iron of a hammer. These doors look very original.
- Powder. It is used more often to cover the entrance doors of luxury homes, as it is a luxury material and is characterized by high strength and durability.
However, it is impossible to independently finish metal surfaces with powder paint - special equipment is required. The product is painted electrostatically, then placed in a special chamber with a heating temperature of about 200 degrees. The polymer powder melts and penetrates the metal structure. - Epoxy. Used for painting technical and industrial premises, very practical, paints any metal.
- Graphite. Advantages: protection of metal from corrosion, resistance to temperature changes.
Advice The choice of paint should be based on its properties, ability to withstand adverse external factors and the type of room where the door leaf is located.
How to paint interior doors made of MDF
The door leaf often has to be changed during repairs - it does not fit into the new interior design. Painting interior doors made of MDF has its own technological nuances. A large assortment of varnishes and paints only complicates the choice. Four compositions on different bases can be recommended for work in residential premises. Due to the caustic fumes, a large percentage of the compositions are applicable only for outdoor use.
How to do it yourself?
Having determined the type of coloring composition, we begin work, which conventionally consists of three stages:
- Selection of all necessary materials.
- Basic surface preparation.
- Coloring.
Let's talk about each of them in more detail.
Materials and tools
To work you will need:
- putty or primer to remove deep scratches;
- sandpaper or wire brush to prepare the canvas for painting;
- container with water, detergent, cotton rags;
- masking tape, protective film or newspapers to protect surfaces;
- dye;
- acrylic varnish for finishing coat.
To save time, use an aerosol, then brushes and rollers may not be needed. Do not forget about means of protection against paint getting on your skin and mucous membranes - rubber gloves, a respirator.
What is needed to prepare a metal (iron) or wooden surface?
The essence of the preparation is to achieve good adhesion of the metal to the paint and give the coating durability.
- First, remove all decorative elements, removable fittings - handles, number, peephole. Seal parts that cannot be removed with masking tape. It is better to remove the canvas itself from its hinges and paint it in a horizontal position.
- To remove the old layer of paint, use a special remover or remove the remains with sandpaper, a sanding machine or a wire brush. The surface is degreased and covered with a primer.
Attention: To seal cracks and irregularities, it is better to use automotive putty.
Varnishing
The procedure is performed according to the instructions:
- The varnish is prepared for use.
- The first layer is applied at the rate of about 150 grams per square meter.
- After waiting for the first layer to dry well, apply a new layer.
- Repeat the drying process.
- Final sanding begins. First, sandpaper with a coarse grain is passed over the surface, then a finer one is used. To avoid lumps forming, spray the area with water.
- The panel is left for several days (from 4 to 7) and polished. For this it is better to use a power tool.
There are many tips on how to properly paint MDF. The main thing is to follow a clear plan and be careful.
