Known since Soviet times, enamel paint continues to be in demand among painting professionals and its characteristics are not inferior to foreign branded analogues. This is due to the high degree of adhesion to all materials used in the construction industry. In addition, it is easy to use, absolutely harmless to health and has excellent decorative properties.
The main advantage of such a paint coating lies in its special properties of impact on the surface. After applying the enamel, it acquires an aesthetic appearance and does not lose its qualities for a long time. Also, its versatility lies in the fact that it can be used with other products intended for application to a flat wall, floor or other surface free of any flaws.
It goes well with primer. Consumers appreciated the fact that upon application there were no signs of smearing or bleeding. This circumstance most irritates people who choose exclusively high quality materials for work. All these points determine the increased demand in the market for these products. Due to its rare characteristics, this brand of enamel is extremely in demand during construction and finishing activities.
Correctness of calculations
To avoid interruption of activities at home or at a construction site, it is important to make the calculations correctly. Before starting repair work, purchase the required amount of painting material in advance. It will help to establish what its consumption will be required when used per 1 m2 if you make the necessary calculations in advance. For this type of paint, it is strictly regulated by regulatory requirements.
In reality, it turns out that everything is not so simple, since consumption indicators are influenced by many factors that should not be overlooked. First of all, this is the composition of the paint itself, as well as the experience and personal skill of the members of the construction team or the owner of the home. It is also impossible not to take into account the level of preparation of the future work site.
All this indicates the need for separate calculations in each individual case. Only then can you accurately name the consumption of PF 115 per 1 m2, and then for the entire area of the room.
Security measures
When painting, wear PPE (personal protective equipment) to protect against the harmful effects of toxic substances on the enamel.
After drying, there is no toxic effect.
It is worth using gloves, a respirator, safety glasses, and a suit. All this is necessary to prevent accidental contact of the composition with the skin or any mucous membranes.
When the enamel comes into contact with the skin, the affected area is treated with a solution based on just soap, slightly warm.
It is important to ensure good ventilation of the room, to provide artificial and natural ventilation:
- artificial - various ventilation systems, hoods;
- natural - open all windows and doors, thereby providing flowing ventilation.
We limit any contact and proximity to sources of fire.
Expense Requirements
According to established standards, 100–180 g of alkyd enamel of this brand is consumed per 1 m2 of living space. In accordance with GOST 6465-76, different manufacturers name this indicator for their products.
The consumption of PF 115 in this case corresponds to reality under the following conditions:
- Re-staining;
- The thickness of the layers is from 30 to 40 micrometers.
The average value from practice shows that to paint an area from 5 to 10 m2, a can of enamel weighing 1 kg is enough.
Classification
Depending on the end user, PF-115 is produced for retail and industrial consumption. The first enamels are sold already with a solvent in the composition, the second - without it, and are a maximum concentrate that requires dilution. But even a retail product should be further diluted before painting.
Pentaphthalic enamel comes in “Economy” and “Standard” versions; they differ in price and quality characteristics. It is logical that the Standard version is of higher quality, it withstands atmospheric conditions better, has higher covering qualities (hiding power) and appearance.
Case Study
For clarity, you can take a fence 10 m long and up to 1.5 m wide, made of galvanized profile sheet. The total area in this case is 30 m2, of which 15 m2 goes on both sides. It follows from this that for uniform application of paint it is necessary to have 2 full cans of material, weighing 1 kg for each side. For double-sided painting, you will need twice as much, that is, 4 cans.
In the construction industry there is a concept - inevitable losses. During the work, the paint remains on the brushes and in the container. Even with very careful waste it will not be possible to avoid accidentally spilling a little on the ground. When intending to paint walls or ceilings, you must take into account the total loss of material, which is about 7% of the expected volume.
Price
The cost of paint is one of the advantages. The price of enamel is low due to the use of inexpensive materials. How much enamel will cost depends on the manufacturer, delivery conditions, and many other factors. But in each store the price range will be approximately the same. The price for 1 kg will vary from 50 to 100 rubles.
A very low price (40 rubles and below) indicates a copy/counterfeit of the paint. It is better to avoid it, it is not made according to GOST standards, the performance characteristics will not meet the required ones.
Painting metal surfaces
When calculating the amount of consumption of PF 115 enamel on metal, many important nuances must be taken into account.
Density degree
Due to the fact that very viscous paint is quite difficult to distribute over the surface, it is unlikely that a thin layer will be achieved. This will inevitably increase consumption. To reduce viscosity use: turpentine, solvent or white spirit. They greatly influence the thickness and help achieve the desired viscosity level.
State of the environment
When working in a room with dry air at normal room temperature, the consumption is greatly reduced. In open areas in hot or windy weather, you should stock up on a large amount of paint.
Application of several layers
Highly absorbent surfaces always require an additional, 3rd layer. Metal structures require 2 full applications. Only by following this rule when painting can you achieve the desired effect. Obviously, in this case, enamel consumption will increase compared to initial calculations.
Dependence of paint volume on color
People who do not often deal with painting are probably not aware of this feature of using PF 115 per 1 m2 of metal. In fact, pure white enamel is the most economical. Any other shade will cause additional waste of money.
Taking this factor into account, in order to save money, you can purchase dark paint and try to achieve a good result with a single coloring. Just 1 layer will help hide the imperfections of the previous base. Since light colors are more transparent, you will need to double the amount of material.
Specifications
Compound
The composition of the coatings includes: pentaphthalic varnish, light-resistant pigments, micronized marble, white spirit, drier, targeted additives. For matte enamels - micronized talc, silicon dioxide.
Application area
It is used for painting wooden, metal, concrete, cement and other surfaces exposed to atmospheric influences, as well as for interior finishing work: painting window frames, window sills, doors, radiators, various wooden and metal objects.
Surface preparation
First, clean metal surfaces from rust and scale, degrease with solvent and coat with alkyd primer. Fill out depressions and potholes with alkyd putty. Wooden surfaces should be scraped and sanded. Clean previously painted surfaces from old flaking paint and sand. Concrete and cement surfaces must first be filled and primed. To remove grease and other contaminants, wash the surface with soapy water, washing powder or soda solution, then dry. Clean surfaces previously painted with chalk or lime paints until the old coating is completely removed.
Temperature range for operation is from +20C to +40 degrees C.
Shades and consumption
PF 115 enamel is still a leader among other paints and varnishes. The extraordinary demand is explained by the fact that it is suitable for any type of surface. It can be mixed with other compounds and with a primer. It is mainly used for painting indoors, exterior wall decoration, as well as working on metal, plastic and wood.
Painters know that the consumption of paint of different shades often differs by up to 4 times. The color of the base being painted also has an impact. More similar tones require less enamel. There are certain rules for accurately calculating your purchase.
Guided by them, you can avoid unnecessary financial waste:
- To paint an area of 7 to 10 m2 white, you will need approximately 100 - 140 g.
- Approximately 60 g of black paint is consumed for a large area of 17-20 m2.
- As for yellow enamel applied to a surface of 5-10 m2, the volume will reach from 100 to 180 g.
- Since blue and green have similar properties, consumption rates will not differ. To paint 17 m2 you need to have 90 g of paint material available. Buying brown paint is much more profitable. For 16 m2 of painted space it will take only 76 g.
Regardless of color, it is always best to apply at least 2 coats. This guarantees the preservation of an impeccable appearance for many years and improves the aesthetic side of the issue. In this way, unplanned repairs can be avoided, provided that all instructions are followed, including thorough preparation of the base. Whatever the operating conditions, they will not affect the appearance of the decor during the year.
Application of PF 115
The main advantage of PF 115 enamel is its versatility. Experts classify this substance as a paint and varnish material for use on all surfaces. That is why it has earned particular popularity in the building materials market.
It is possible to combine enamel with other coating agents, such as primer. After application, the coating is not subject to spreading or smearing.
It forms a dense film with a smooth coating.
The name of the enamel begins with the abbreviation PF, which stands for pentaphthal or alkyd-based resin.
This type of paint is used for :
- external type with finishing;
- for covering various types of surfaces: metal, wood or plastic;
- for carrying out work in the interior of the room.
This type of enamel can withstand high atmospheric loads , such as snow, rain and low and high temperatures. That is why it is widely used both in home painting and in external work.
The application of enamel to the surface to be coated can be done using an ordinary brush, dipping or pouring. Spraying is also allowed if a special apparatus is available.
The substance contains the following components:
- Pentaphthals , which experts classify as polymer substances.
- Resins produced by various, including modified, methods. They allow you to speed up the drying process of the surface.
- Semi-dried oils and resins with special composite mixtures in small quantities.

Surface, tool and work skills
These essential components are also of no small importance when calculating the amount of enamel:
To ensure the strength and required density of the coating when painting a porous or uneven surface, several layers will be required. In this case, a special primer will help reduce the consumption of painting material.
Tools to get the job done. It is preferable to use a roller rather than a brush as it is much more effective. The pneumatic or air spraying method is less profitable in terms of monetary costs.
Personal mastery. A painter who has the appropriate qualifications copes with the task many times better and paints the surface subtly and evenly. A beginner in this business is unlikely to be able to apply an even layer without wasting paint.
Consumption of oil paint per 1m2 on metal.
Calculation of oil dye for metal, calculated in grams, is the most convenient indicator, since most often we know information about the surface area in advance. The area needs to be calculated, taking into account all the unevenness, the level of absorption, how many layers need to be applied.
Among the most significant factors determining material consumption, color should also be highlighted. The number of layers and quality of the coating will depend on this. Since color density depends on pigmentation, costs will vary depending on the tone.
How to reduce the amount of paint material
You can use enamel economically only if you have the appropriate knowledge of painting art. First of all, the key to future success is a carefully prepared foundation. This is what will determine the rational use of paint. The surface must be free of any defects - crumbling parts, remnants of the previous coating, various damage and contamination.
The primer should be applied in layers. If you do not have sufficient experience in carrying out painting work, it is better to use the services of specialists who are familiar with all the intricacies of this work and who will ideally cope with the task.
Peculiarities
The versatility of alkyd enamel allows it to be used for treating various surfaces. During interior decoration, the composition is indispensable for painting the radiator, but before starting work, you should definitely make sure that the material is able to withstand high temperatures.
When painting wood, it is better if the alkyd enamel dries for at least 30 hours. We should not forget that it is always possible to reduce the viscosity of the product by using a solvent.
Matte alkyd enamel coating, characterized by durability and reliability, which can be purchased at an affordable price for the consumer.
Useful tips for using enamel
When carrying out work, it is advisable to pay attention to the following points:
- Before applying the next layer, the previous one must dry thoroughly. Under natural conditions, this will take about a day. This circumstance should not be ignored, since the volume of paint will decrease. To speed up the process by 1 hour, the surface is heated to 110°. The condition of the coating is checked by applying the palm of your hand. If it is not completely dry, it will feel sticky.
- A perfectly smooth surface can be achieved by using a primer.
- For the best application of paint, you need to purchase a roller or brush with silicone bristles. Due to the fact that polymers do not absorb enamel, losses will be insignificant.
- You need to choose a trusted company that has the appropriate certificate. Saving on material may subsequently result in additional costs.
