Paint Applications

Paint is universal for use.. It is used for painting wooden, concrete, plastered, brick, metal surfaces of various types: walls, ceilings, window and door frames, fences, outdoor furniture, pipes, metal frames, etc.

On surfaces with increased operational load, the paint requires additional protection against abrasion.

Enamel based on pentaphthalic varnish is mainly used to protect metal structures operating in atmospheric conditions. PF-115 is applied as part of complex coatings using primers. To paint concrete, brick, walls in wet conditions, moisture-proofing impregnations are additionally used.

It is possible to apply enamel on previously painted surfaces, provided that the old coating is made on a pentaphthalic basis and does not have blisters, cracks, crumbling areas.

Surface preparation

Wooden bases it is necessary to pre-sand, dust, remove dirt. The metal must be cleaned of rust, dirt, residues of old coatings. The surface is degreased. The degree of purity of the material before painting is not lower than 2 according to GOS 9.402.

Mechanical cleaning is carried out to the degree of St 3, abrasive blasting - up to Sa 2 ½. It is recommended to apply PF-115 enamel on a previously primed surface. Suitable for work soils FL-03k, EF-065, GF-0119, GF-021 and others.

Application Methods

PF-115 enamel can be applied in several ways: manually with a roller or brush, by pneumatic spraying or airless spraying, in bulk, by dipping.

For manual staining, the viscosity of the composition should be in the range of 55-70 s, for pneumatic spraying - 28-30 s.

Airless spray parameters:

• paint pressure - 13 MPa,
• working viscosity - 50-80 s,
• the ratio of pressure increase is 1: 25-1: 45,
• nozzle diameter 0.28-0.48 mm,
• torch angle of 20-60 degrees.

Metal

Staining begins after the primer has completely dried. To prepare the metal surface, the compositions VL-05, GF-021 and other types of metal primers compatible with pentaphthalic varnish are used. Structures with traces of corrosion are additionally treated with rust converters immediately before priming.

Special tools will slow down the oxidation processes in existing foci, turn friable oxides into solids and prevent the appearance of new foci of rust.

Tree

Technical characteristics of the PF-115 enamel allow you to apply it without priming, but in 2-3 layers. It is recommended to pre-soak the wood with flame retardants, antiseptics, fungicides, and other protective agents that are not part of the enamel.

Mineral bases

Plaster, concrete, brick can be painted without priming. Thoroughly dry the surface before starting work.. Enamel forms a dense vapor-tight film, so residual moisture in the pores of the base can cause cracking at a low temperature, provoke mold growth, etc.

Fresh concrete walls, foundations, other structures can be painted no earlier than six months after the end of construction.

Security measures

Enamel is toxic and combustible. The paint contains volatile solvents, lead and chromium compounds that are potentially hazardous to human health.. In high concentrations, enamel vapors cause irritation to the eyes, skin, and respiratory tract.

During operation, it is necessary to comply with the basic requirements of industrial sanitation: use protective clothing, gloves, a respirator, and ensure intensive ventilation of the room. Dried paintwork is not harmful to human health.

Scope of application

Most often, PF-115 enamel is used for painting central heating radiators, doors and windows. PF-115 is weatherproof, therefore it is often used for painting all kinds of wooden and metal structures on the street: arbors, benches, verandas, fences, utility structures. Resistance to moisture avoids peeling and the appearance of bubbles on the coating (this is prevented by a protective film that holds the enamel on the painted surface).

Another important argument in favor of this enamel is its ability to withstand ultraviolet radiation. Due to this quality, the coating does not fade or fade. PF-115 is used for coloring not only wood and metal, but also drywall sheets, brick and concrete surfaces.

Composition and labeling

PF-115 enamel is a suspension in which there are pigments and special fillers in an alkyd mixture. The main component is the semi-finished product of pentaphthalic varnish - PF-060, as well as titanium dioxide. As a solvent, white spirit or another desiccant is used. Modifiers are used to give PF-115 additional properties. PF-115 includes finely dispersed dye.

Enamels are available in different colors, with the appropriate additives. For example, white paint, which contains zinc white. Carbon black is added to the gray paint. In blue, iron azure is used as a modifier.

The color assortment is quite diverse, although mostly limited to basic colors. Various shades are available, but their list is limited (five dozen options). The fact is that in the case of shades (like with cherry) it is difficult to ensure the proper quality of enamel manufacturing. Therefore, such paints are assigned not the highest, but only the first grade in quality.

The marking of this paint material indicates its composition (PF - pentaphthalic base) and color palette (115 - number of the corresponding series). The production standard is GOST 6465-76, which was amended in 2001 to improve product specifications.

Manufacturers produce two varieties of paint produced for different consumers - industrial and retail. The differences between the modifications are in production technology. Industrial dyes are offered in concentrated form. Such enamels need to be diluted with solvents. But products for the retail buyer are available in a diluted form. However, even a retail product must be diluted further.

Enamel Technical Features

For the PF-115 enamel, the following technical characteristics are characteristic:

• the formation of a glossy coating (gloss level is 50%),
• adhesion level - up to 1 point (there are also oil options with lower adhesion),
• the proportion of non-volatile components ranges from 49% to 70%,
• bending elasticity index - not more than 1 millimeter,
• drying speed of the coating at room temperature - up to 24 hours,
• specific hardness - from 0.15 to 0.25 conventional units,
• conditional viscosity index - from 60 to 120 conventional units,
• the ability to resist moisture - up to 2 hours, fuels and lubricants - up to 24 hours, aggressive detergents - up to 15 minutes.

The paint is characterized by high hiding power. On average, the surface service life at low temperatures is 4–5 years, but in hot climates it does not exceed 1 year.

The disadvantage of PF-115 is the fire hazard of the coatings and a fairly high level of toxicity. When applying such enamel indoors, safety precautions (protective clothing and goggles, a respirator) should be observed.

State standards

The production technology of PF-115 is regulated by GOST 6465-76. This standard was created by the Ministry of Chemical Industry of the USSR in 1976.

There are other standards established by the state that regulate certain aspects of the production process.

The list of GOSTs, which contain information about this enamel:

9980.1 - the acceptance rules are set out,

9980.2 - the order of sampling is determined,

9980.3 - the rules for the use of packaging and labeling are described,

12.1.005 - the hazard classes of the components present in the paint are listed,

12.1.044 - fire hazard is characterized,

12.3.005b 12.1.004 - sets out the requirements for production and testing processes, as well as for the use of enamel.

GOSTs also regulate the use of protective clothing and devices that ensure the safety of workers.

Painting

The universal qualities of PF-115 make it possible to paint the surface at an air temperature of 5 to 35 degrees Celsius. For applying paint use brushes, brushes, rollers or spray guns. Immersion staining is also used.

Metal structures are painted with at least two layers of enamel after preliminary priming. For high-quality painting of wood, brick, concrete or plaster, you need two or three layers with a thickness of 18-23 microns each. The variation in thickness is associated with differences in the structure of the material being painted and the color of the paint.

After applying a layer of enamel, the surface should dry. Drying at 20 degrees takes up to 24 hours. When faster drying is required, the use of high temperatures (100-110 degrees) is allowed.

After the enamel dries, the surface becomes glossy, uniform, smooth. It is resistant to abrasion, weather and chemical influences. PF-115 is compatible with almost any type of paintwork.

Enamel consumption

One of the advantages of the PF-115 is its economical consumption. Specific indicators depend on many circumstances:

1. Application Method. When working with a sprayer, the paintwork material is spent less economically compared to using a brush.
2. Manufacturing technology.PF-115 is produced not only in accordance with GOST, but also in accordance with TU. In the latter case, the consumption is approximately 50% higher.
3. The degree of preparation of the base. A well-primed surface reduces the consumption of paints and varnishes.
4. Consumption per 1 m2 even depends on the color of the enamel. The most economical option is black paint, and the most wasteful is white. Other colors are intermediate.
5. Type of material to be painted. Consumption per 1 m2 for metal will be less than when painting wood, which absorbs part of the paintwork.

Enamel consumption - from 100 to 180 grams per square meter of one layer.

Paint manufacturers

Enamel PF 115 is produced by many Russian enterprises. The Yaroslavsky Color company produces it in a wide range of colors (several dozen colors and shades). Also, the products of such brands as Norma, Host, Profilyuks have proven themselves well.

Note! A quality product must have a certificate of conformity.

Products from different manufacturers are distinguished by their consumer properties. So, Lacra enamel is very decorative, has good adhesive qualities. A wide selection of shades is offered. Most of the options for this enamel give a glossy effect. The maximum shelf life of the paint material is 2 years.

Varnish-and-paint material from Tex Optimum is fast drying (5-8 hours). However, each subsequent coat is recommended to be applied no earlier than 24 hours later. The shelf life of the paint is shorter than some competitors - 1.5 years. PF 115 from this manufacturer fits well on drywall, fiberboard and particleboard.

Paint from Tex Fazenda has a semi-matt coating tone, increased resistance to external influences and is well cleaned from pollution. The painted area is able to withstand even the solvent.

Enamel of the Bio trademark is intended for use in medical and educational institutions, since LKM contains a special bioadditive with bactericidal and virucidal properties. Technical standards governing the production of enamels with such properties are contained in GOST 10.03.76.

Storage conditions

Since PF 115 enamel is flammable, it is forbidden to store cans in the immediate vicinity of an open flame. It is also unacceptable to find the composition in direct sunlight or in a humid environment. The paintwork composition retains its working qualities at air temperatures from 40 degrees below zero to 40 degrees above zero.

Manufacturers usually give a one-year warranty on their products. However, warranties are retained only if the enamel is stored in unopened packaging. Otherwise, the composition dries very quickly.

How to decipher the name

Enamel PF-115 was developed and launched on the market. over 60 years ago. Despite the fact that there are more modern compositions, it is still considered one of the most popular for various kinds of finishing works. Its popularity is justified by affordability and breadth of application. Paint is made in accordance with GOST 6465-76.

Attention! To reduce the cost of the composition, individual manufacturers change the chemical composition of enamel, which is often negatively displayed on its operational properties. You can determine such a product according to information on the bank on the conformity of technical specifications. Almost always, the paint according to GOST is the best.

The name PF-115 is a marking. The letter designation, consisting of the characters "PF", means that as a bonding base in enamel is used pentaphthalic varnish. This substance belongs to alkyd resins. It is thanks to this that pentaphthalic enamel can be used for exterior and interior use. The numerical part of the name also carries information. The number "1" indicates the possibility of using paint in various temperature conditions and the inscription "15" is a serial number, which is determined in GOST.

Physical condition and composition

As for the physical state, alkyd paint is a viscous mixture of a liquid with a suspension of solid particles. It contains:

• color,
• pigments
• White Spirit,
• desiccant
• pentaphthalic varnish,
• titanium dioxide.

Depending on the shade, the chemical composition of the enamel may vary. This is partially expressed by a different percentage of components. Excellent color coders have their own richness. On the conditional volume of one paint you need literally a couple of drops of a color additive, and for others ten times more.

The difference in chemical composition directly affects the operational properties of the dry coating obtained by drying the paint layer. Most sustainable is white enamel, as it is added to 28% pentaphthalic varnish. In the blue paint of it 26%, and in gray only 20%. Many components for ensuring and fixing color can make the composition more wear-resistant, therefore it cannot be said that white enamel will be better in terms of operation.

Purpose and use

PF-115 universal paint, due to which the composition can be used for coloring:

• wood
• concrete structures
• cement plasters
• bricks
• stone
• metal.

Attention! Although the paint adheres well to various materials, it cannot be used on surfaces subject to extreme heat. First of all, this applies to the roof. Created with her help the decorative layer on slate or tin sheets may crack and burn out. A combination of ultraviolet and heat destroys it.

Enamel should be applied only in compliance with the temperature regime from +5 to + 35 ° C. Its use for coloring hot radiators and other warm utilities is unacceptable. In this case, an unnaturally rapid evaporation of volatile substances occurs, as a result, accelerated drying is observed. Such a layer does not gain sufficient binding properties. Painted Surfaces prone to cracking,color loss and peeling off flakes.

Enamel is ideal for indoor use, as well as for painting surfaces on the street that are in the shade or do not heat up. Paint can be used as the only means of protection and decoration, and such is applied to special primers, antiseptic impregnations and rust converters. Applying PF-115 on hygroscopic surfaces that will be in an important environment, the use of antibacterial and antiseptic additives is required. The paint itself does not have such properties.

Dried enamelled surfaces can be used in various thermal conditions. from -50 to + 60 ° C. To ensure this stability, paint should be applied in several layers. Single-layer application is allowed only if old coatings are renewed without cracks or blisters. Even with multi-layer application, the composition retains elasticity.

What tools are needed for painting

PF-115 alkyd enamel is compatible with any painting tools:

The most quick application provides pneumatic or electric spray. Slowest to work with a brush. When spraying enamel, more solvent is added so that the nozzle of the paint gun can create a normal spray pattern. The degree of dilution with white spirit or solvent may vary between manufacturers, as well as the shelf life of the paint. Information on this can be found on the back of the enamel can. The use of the roller provides high speed, but is accompanied by increased consumption of material.

What is the paint consumption depending on the color

Light transmission of different colors is different, so in some cases 2 layers of enamel are enough, and in others from 3 or more. For this reason, the actual consumption of PF-115 in different shades may vary. 4 times. This largely depends on the color of the base itself, which is painted. If there is a suitable shade of soil, paint consumption is reduced.

Table 2. Technical data on the consumption of PF-115 per 1 m2 (depending on its color, when applied in a single layer).

As seen, the most economical in terms of application is black paint. When choosing of red color would need 200 g / m2. The calculation proposed in the table displays the flow rate when applying one layer. The actual cost of enamel will depend on how many times it is covered. A more accurate calculation can be done by the formula, multiplying the flow rate indicated in the table by the number of layers and coefficient 0.9.

The presence of a coefficient in the formula is due to the fact that each new layer is less expendable than the previous one. When planning to use PF-115 enamel, you need to consider that painting work will require considerable time. The fact is that break between layers should be 24 hours at room temperature. That is, re-staining occurs after the previous coat has completely dried.

General step-by-step instructions for using PF-115 paints

To achieve maximum performance properties of the coating, it is necessary to comply with all painting conditions. The sequence of actions is as follows:

Step 1. We clean the surface of dirt, grease, dust and other layers.

Step 2 Dry the surface if necessary.

Prices for popular heat gun models

Step 3 We treat with antiseptics (if it is a tree or a mineral base) or with a primer, in the case of metal.

Step 4 Mix the paint, if necessary, with the addition of a solvent.

Step 5 We paint in 2-3 layers with an interval of 24 hours.

How to paint metal

All types of metal, whether steel, cast iron, aluminum or copper, are painted only on top of the previously applied primer. In its quality may apply GF O119, VL O5, GF O21 and similar compositions. Primers compatible with enamel are named “O”. PF-115 may be used without soil on non-essential surfaces operated in dry conditions at normal temperature. With this solution, the first layer of enamel is diluted with white spirit in the ratio 50%. The liquid composition penetrates into the recesses on the metal surface, and after solidification creates a good basis for the normal adhesion of subsequent layers.

It is not allowed to apply PF-115 on rusty surfaces. Corrosion stratification must be treated with special rust converters. Such chemicals are applied only after cleaning from scale and dirt. This is done using a brush for metal or angle grinders. After chemical interaction, the corrosion products turn into a solid base, which can become the basis for staining. Enamel can be applied to metal by any technical means. Considered optimal 2 layers excluding primer.

How to paint a tree

The surface of the wood is painted with enamel without the use of a primer. Considered optimal 2-3 layers paints. This amount is due to the ability of wood to absorb moisture. Ideally, pre-treatment with antiseptic and fungicidal agents. You need to make sure that they are compatible. Most of these compounds are designed specifically for acrylic paints. When combined with alkyd enamels, the latter swell. The use of preliminary impregnations reduces the moisture absorption of the tree. This reduces actual paint consumption.

Note! If it is necessary to achieve high smoothness of wood without a protruding pile, after applying and hardening the first layer, light grinding of the surface is allowed. Subsequently, the treated area is dust-free and stained 2 more times. In this case, between them it is necessary to observe a technological pause for drying.

How to prepare paint

Enamel PF-115 delivered at the factory bank is ready to use. She does not need dissolution. However, during prolonged storage, evaporation of its solvents is possible. As a result, the composition becomes thick. To return its fluidity, a white spirit or solvent is used. The use of undesirable gasoline and kerosene instead, as this changes the shade of enamel and the degree of gloss.

After opening the can of enamel, its contents must be thoroughly mixed. The formation of dried peel on the surface of the paint is allowed. If a hand tool is used, it can be left. For a spray, the paint mixed with a crust needs to be filtered further. The thick pigment of enamel settles down during storage, so when mixing it is necessary to pay special attention to dissolving the thick suspension at the bottom. The solvent is added in several approaches. In the process, the particles of paint settle, so it must be periodically mixed.

Lacra

Technical characteristics of this brand provide enhanced decorative properties. It has good adhesion. As a result of its application, a glossy surface is formed. Shelf life of paint Lacra up to 5 years. In the assortment of the brand of matte surfaces there is only white color.

Optimum

Optimum differ from other paints accelerated drying about for 5-7 hours Despite this, a subsequent coat is applied anyway after 24 hours. The service life of painted surfaces is 18 months. Most commonly applied for interior decoration.

PF-115 with antiseptic additives

Multiple brands produce marked enamel BIO. Biological additives are added to its composition, inhibiting the development of bacteria, viruses and fungi. This enamel belongs to the class of new coatings. It is used for painting walls, ceilings, windows and doors. It is recommended for internal repairs. in medical institutions, kindergartens, schools, etc. The guaranteed shelf life of enamel due to the presence of bioadditives is 12 months.

Compatibility with other paints

Mixing PF-115 enamel with coloring agents other in composition is not allowed. If necessary, pentaphthalic paints of different colors can be mixed to achieve the desired shade. When choosing this composition for updating previously painted products, it is necessary to consider what kind of enamel they were coated with. If the new coat of paint is incompatible with the old, cracking, bloating and peeling off of the fresh coating will occur.

Pay attention to the amazing reflective paint with its unique properties!

Apparently, PF-115 unsuitable for coating surfaces previously applied alkyd-acrylic, alkyd-urethane, melamine, urea, polyurethane and perchlorovinyl paint. PF-115 is a universal composition, but it cannot be called the best in all respects. Enamel creates good adhesion and color depth only if the application technology is followed with pauses between layers and preliminary surface preparation.
