Acrylic paint for heating radiators, how to dilute it

How not to dilute enamel for heating radiators

The appearance of cast iron heating radiators requires periodic updating. This is necessary not only for aesthetics, but also to extend service life. Aluminum and steel radiators have a special powder coating and, as a rule, do not need to be repainted. Today there are many varieties of paints on sale designed specifically for radiators. Enamels are best suited for cast iron batteries. Which ones exactly, how to apply them correctly, what can and cannot be used to dilute enamel paints - we will talk about this below.

Types of enamels for cast iron batteries

Despite the modern abundance of heating radiators, cast iron batteries continue to be in demand. There are quite a lot of reasons for this, and it makes no sense to list them. Cast iron radiators require periodic surface painting. In this case, the paint must meet the following requirements:

Maintain a temperature of about 80 C.
Be environmentally friendly.
It is good to protect the surface and give it an attractive appearance.
Maintain the original appearance for a long time.

During the Soviet shortage, the choice was, to put it mildly, small: oil paint or silver paint. Today, several types of enamels are used to paint radiators:

Alkyd - creates a durable coating on the surface that can maintain the integrity of the structure for a long time. Among the shortcomings, one can note, first of all, a pungent odor that does not disappear for a long time. You can dilute alkyd enamel to the desired consistency:

White spirit;
Solvent;
Xylene;
Turpentine;
646 solvent.

It is highly not recommended to dilute paint with gasoline and diesel fuel.

Water-dispersed alkyd enamel

It dries very quickly, does not have a repulsive odor, and is strong and durable. It is diluted, as the name implies, with ordinary clean water. Other solvents are not recommended.

Acrylic enamel

Advantages - the surface does not need to be primed, the paint is very easy to apply, it dries quickly and does not smell. Acrylic paints are diluted with water, alcohol diluted with water, as well as special acrylic thinners. Universal solvents are not suitable for acrylic paints.

In order not to make a mistake when choosing a solvent for enamel, you need to clearly know its composition. The universal solvent is considered to be 646 nitro solvent. However, some enamels cannot be diluted with products that contain acetone, as they curl. Manufacturers always indicate recommended enamel thinners on the label, which cannot be replaced with analogues.

Popular products

There are a large number of paint solvents, as one might understand. The main thing is not to get confused when studying symbols and markings.

P-4 is a popular variety that contains toluene and acetone. It is used when dissolving alkyd paints and enamels for metal, compositions with chlorinated polymer. All ingredients form a successful combination, thanks to which the paint easily acquires the desired consistency per 1 kg.

Upon completion of painting, a film appears on the surface, serving as additional protection. This composition is mainly used for degreasing surfaces.

Solvent R-4 has the following properties:

high volatility;
flammability;
the need to observe safety measures when working.

Composition 646 has become even more popular; it is easy to use both in industry and in domestic conditions. Can be a degreaser and solvent. The main advantage is its wide scope of application. Multifunctionality and technical characteristics are among the main advantages.

How to dilute acrylic paint?

Acrylic paint is a safe, non-toxic paint and varnish material made on the basis of pigment, a binding component, and water. After evaporation and complete drying of the water base, a frost-resistant, elastic, cracking and delamination-resistant protective coating is created. This type of paint is used for painting wooden, metal, and plastered surfaces.

It has special advantages compared to other paints and varnishes:

– environmental friendliness – complete safety for health and the environment due to the absence of toxic substances;

– the widest color palette;

– comfort of use, achieved by quick drying of the painted surface, ease of use, including washing;

– absence of unpleasant odor, which allows you to dispense with a respirator mask when working;

– long service life – at least ten years;

– the acrylic layer does not allow water to pass through.

There are several types of acrylic paint depending on the following indicators:

– application option (external and internal work);

– resistance to environmental factors (moisture resistance, light resistance, resistance to mechanical factors);

– gloss and degree of whiteness;

According to its structure, acrylic paint is a thick material that requires dilution before work to ensure convenient application and uniform distribution. The need for dilution arises after the material has been open for a long time.

There are several options for thinners.

Application method: Designed for application by brush or roller. Wash working tools with water immediately after use.

Coating structure: Preliminary preparation: Wash off possible mold deposits with water. Wash surfaces with Capatox or FungiGrund and allow to dry thoroughly. At the same time, comply with legislative and departmental regulations (for example, the procedure for using biologically active and hazardous substances).

Primer or intermediate coat: Malerit-W diluted to max. 10% water.

Finish coat: Malerit-W, diluted to max. 5% water.

Flow: Minimum flow approx. 140 ml/m2 per 1 pass on a smooth substrate. On rough substrates the consumption will be correspondingly higher. The exact consumption is determined by test application. The thickness of the painted layer significantly affects the duration of action of fungicidal and bactericidal agents. Therefore, Malerit-W should always be applied in a thick and even layer. You cannot use a product with less consumption than indicated.

Application conditions: Lower temperature limit for processing and drying: Air and substrate temperature must be +5 °C.

Drying/drying time: At +20 °C and 65% relative air humidity, after 4–6 hours the surface is dry and ready for further processing. Complete drying and ability to bear loads is achieved in approximately 3 days. At lower temperatures and high air humidity, the drying time increases accordingly.

Note: In areas where food is stored, it is not permitted to use paints and varnishes containing solvents. Therefore, in these rooms, only OptiGrund ELF should be used for priming. These rooms, after coating with Malerit-W, must be ventilated for at least 3 days before further use. Malerit-W darkens in reaction to heavy metal salts dissolved in water, such as copper salts. In this case, special consultation should be sought. Indeko-W or Fungitex-W should be used on interior surfaces damaged by mold or susceptible to mold, especially in areas used for industrial purposes.

When using Caparol-Tiefgrund TB indoors, the coating may emit a typical solvent odor. In this regard, care should be taken to ensure good ventilation. For sensitive areas, use the aromatic-free and low-odor AmphiSilan-Putzfestiger.

Covering power: Paintings made with Malerit-W can be treated with dispersion paints or paints based on polymerization resins, as well as plasters. Oil-based paints and paints based on oil-alkyd resins are not suitable as the substance contained in Malerit-W hinders the drying process.

Diluting acrylic paints with water

The basis of acrylic paints and varnishes is water, so it is advisable to use it to achieve the required consistency. An important point: you need to use only clean and cold water, standing for several hours or distilled, to prevent interaction between the components of the paint and varnish material and the thinner.

– dilution with water 1:1 – the material can be used to create a base layer, the paintwork lays down evenly, without smudges or sagging, forming a uniform coating that effectively protects the surface from corrosion and aggressive environmental influences;

– 1:2 – the consistency is more liquid, allowing you to create a thin and even layer, the paintwork material saturates the brush or roller well;

– 1:5 – creates “colored water”, which is used to color textured details; the composition is well absorbed and fills depressions and other depressions on the surface;

– 1:15 – the proportion is not used often, it is intended to create a transition between tones (gradient); in fact, it is no longer paint, but colored water.

After applying acrylic water-based paint and varnish material, you must immediately thoroughly clean the tool used. This is explained by the fact that after drying, water-based acrylic paintwork becomes water-resistant. And, accordingly, rollers, brushes and other painting tools, once dry, cannot be cleaned.

Which solvents are suitable for which paints?

Let's now take a closer look at the types of solvents and their applications.

Solvent for alkyd paints

The composition of alkyd paint includes alkyd resin and drier additives, which are responsible for the speed of drying of the paint.

Alkyd paints are good because they perfectly protect the surface from corrosion inside and out. Most often, alkyd paint is used for painting ceilings, walls, furniture, radiators, window frames, and doors. But you need to take into account that it is not very environmentally friendly and retains an unpleasant specific odor for a long time after drying.

Regarding which solvent to use for alkyd paints, we note that it is best to do this with turpentine, drying oil, or white spirit. The latter is the most popular. It is purified kerosene. Many people use regular kerosene to dilute alkyd paint. But do not forget that it is very toxic and much more expensive than white spirit. For this reason, we do not recommend that you use it.

Solvent for oil paints

Oil paints are diluted with organic solvents, which can evaporate quickly.

These liquids require careful handling as they can penetrate microcracks in the soil. You should also not forget that strong dilution of oil paint with a solvent can lead to destruction of the paint layer - the paint will become fragile and friable.

At the same time, the solvent for oil paints has good permeability, it promotes the penetration of oils between layers of paint, making the paint look much more beautiful and become stronger.

Also note that some thinners make the paint lighter, but after drying the paint returns to its original color.

What kind of solvent can be used for oil paints? Let's take a closer look.

1) You can use a mixture of white spirit and gum turpentine in a 1:1 ratio. But such a thinner for oil paints can be used to prepare paints for sketches.

2) White spirit itself is used as another solvent for oil paints. It was discussed in more detail above. It is widely used for cleaning paint from palettes and brushes after work. But in construction work it is not used as a solvent for oil paints, since it has low dissolving ability and high permeability.

3) The most effective solvent for this type of paint is pinene. It is a product of rectification of gum turpentine, as a result of which the resinous parts of the turpentine are separated. Another advantage of pinene is that it is much less susceptible to oxidation than turpentine. It is worth considering that it is not recommended to use turpentine in painting, as it is prone to yellowing. When diluting paints with pinene, you need to take into account that the gloss will also decrease.

All thinners should be stored in tightly closed containers.

Finally, we would like to add that today they have begun to produce special turpentine for artistic paints, and many also use any oil of vegetable origin.

Dilution with special acrylic thinners

Dilution with water or water with alcohol is only permissible when using a roller or brush. Paint sprayers and spray guns (painting equipment) require the use of acrylic thinners, the brand of which must be indicated by the manufacturer on the packaging. They have a specific smell and transparent appearance. The required amount of addition of such liquid depends on the scope of application, temperature and humidity of the external environment. Depending on the composition, acrylic solvents create a matte or glossy layer on the surface. Different coloring effects are achieved using a certain proportion, which is usually indicated on the thinner packaging.

Advantages of using acrylic solvent:

– accelerated drying time;

– the ability to create a matte or glossy surface;

– formation of an even layer without streaks and white deposits;

– chemical purity, compared to water;

– increased stability of paint characteristics.
