No, you cannot. The essence of the protection of the farrow metals from the corrosion using galvanizing is to provide a direct contact between two metals (iron and zinc). In case if such a contact is established, the laws of electrochemistry start to act; and according to them in the pair of two metals corrosion occurs only to more active metal. In our pair the more active metal is zinc; therefore, first of all, it will be subjected to corrosion. While the iron is coated by the zinc coating, iron corrosion will not occur. In case if there are intermediate layers between iron and zinc (such as grounds, rust converters, etc.), the electrochemical contact shall not be established, and as a result zinc coating shall perform only the isolation from moisture (as a simple paint) function. Therefore, in order to get the proper anti-corrosive protection, before using the galvanizing, you should ensure the best possible contact between iron and zinc. The most efficient way to reach this is a mechanical treatment (sandblasting, shotblasting, metal brushes, etc.). After such a treatment, iron is devoid of extraneous layers and has some roughness, and is conducive to the best electrochemical contact between the metals. The quality of the contact could be raised by the additional degreasing of the metal by xylene or solvent. The effectiveness of applying galvanizing on such surface is the most cost-effective.

In case if you apply several layers of Galvanol, exposure time between layers should be about 30 minutes. The most likely reason of bubbling of the finishing coating is because there were too little time break between the application of the second layer of Galvanol and the finishing coating. For the complete drying of the anti-corrosive coating 4-6 hours are required. Only after this period of time the finishing coatings can be applied. In case if the finishing coating was applied earlier, its local detachment (bubbling) is possible due to the evaporation of the solvent from the Galvanol layer. Unlike to hot galvanizing, any lacquer-and-paint materials can be applied on the top of the galvanizing layer. In case if you use Galvanol mixture, the special paints are not required.

Yes, zinc coating, made by the Galvanol mixture is electric conductive.

Galvanol possesses a very high density. One litter of Galvanol weights 2,5 kg. So alone a very noticeable delaminating of the material occurs (heavy zinc powder gravitates to the bottom). It is very complicated physically to stir manually the 10 or 40 kg bucket. And the quality of the coating directly depends on the homogeneity of the mixture at the moment of its application. That is why it is mostly recommended to pay a particular attention to the mixing and use for the mixing the special tool.

Most probably the reason is in solvents. Solvent, on which Galvanol mixture is based, after opening the container is prone to evaporation. If the works are done not in one day, and the Galvanol bucket was not tightly closed, evaporation can be noticeable. In such cases Galvanol can be diluted with xylene. If you use poor solvents to dilute Galvanol, the further flaking of the zinc coating is possible.

Yes, you can. Moreover, the older the zinc coating is, the better it keeps anti-corrosion coating due to the fact that the old zinc coatings have a natural roughness. In case if you need to reconstruct the new zinc coating, the best results Galvanol shows while galvanizing with mechanical treatment (creation of roughness). You can reach even better results if the mechanically protected surface is additionally degreased with xylene.

No. It is not recommended to add anything external to the Galvanol mixture. The essence of Galvanol is limited precisely to protect the metal from the corrosion. It copes with this task magnificently. In case if you need a particular color of the finishing coating, it is recommended to apply the paint you need on the top of the galvanizing coating.

Since Galvanol is primarily a composition for the galvanizing, its main task is an anti-corrosive protection of the metal. Its gray color is not standardized on RAL scale. Galvanol’s shade can fluctuate from more light to dark. Color is not a defining characteristic for galvanizing. The main and decisive characteristic of materials such as galvanizing should be the effectiveness of their protection against the corrosion (protective power).

Yes, sure. Galvanol allows to use the method of airless spraying, as well as the method of pneumatic dispersion. The difference of applying of these two methods of galvanizing is in diameter of the nozzle and the proportion of solvent dilution (pneumatic spraying involves a bit more dilution than airless spraying method). You can find the more detailed information in Technological Rules of Application.

Yes, sure. Galvanizing can be applied manually, as well as to manually prepare metal for the application. For sure, this is a more time consuming process. However, even in the specific manufacturing, there is not always possible to completely eliminate the use of the manual working. For instance, the use of the manual working is advisable in galvanizing of the welded seams and other hard-to-reach places, before applying the main layer of galvanizing on the entire surface. Galvanol can be applied with a brush and a roller. Its efficacy does not reduce from this. While manually applying the more important becomes the “human factor”: the end result might be hampered by uneven coating, lack of the roughness after the rust removal, degreasing failure, usage of the poor solvent, etc.

The reason to make such statements give us the testing results, performed in 2010 by the Central Scientific Research Institute of Corrosion and Certification (CSRICS). We do not doubt in effectiveness of Galvanol, because we work with this material since 2008; and we have only positive comments about it. Please note that Galvanol is not a paint, but precisely the galvanizing”, because there is no sense to produce “just the paint” with 96% of zinc content. Galvanol indeed creates a zinc coating, which provides cathode protection. If you have any doubts, you can solve them testing material yourself. If you are not satisfied with this option, you can simply use other materials for metal protection. Or nothing at all. Everyone chooses for himself.

Lifetime of the metal with Galvanol galvanizing coating is measured in years. How many years shall serve the galvanizing coating depends on the quality of preparation of the surface and on the quality of the works done. We have the official conclusions on this. You may have a look on the conclusions of the lifetime of the surface dependant on the quality of the surface preparation on our website. You can also see on our website the results of testing of Galvanol in chemically aggressive environment (salt fog).

Yes, the lifetime of the zinc protective layer depends of its thickness. Iron does not corrode while the thread protection in the form of zinc exists. As soon as zinc coating is spent, the corrosion of iron shall begin. Therefore, the more zinc the better, but within a reasonable limit. Practice shows that, if Galvanol is applied properly, maximum is 200 micron coat in iron not subjected to deformation, and 160 micron for deformable iron. Moreover, you need to keep in mind, that qualitative protection is reached by the application of the multiple thin layers of the anti-corrosive coating. One layer of Galvanol with correct consistency applied with paint spray has thickness of about 40 microns.

Indeed, Galvanol creates a matte coating on the metal. However, we produce mixture Alinol for the purposes of creating gloss on the metal protected by Galvanol, imitating the hot galvanizing coating. This mixture is based on the aluminum powder and same with Galvanol polymer filler content; therefore, is perfectly compatible with it. Alinol is not intended for the stand-alone (without Galvanol) application on the metal. In addition to the specialized coating composition, Galvanol glossing can be achieved with polishing. However, please keep in mind, that in the process of polishing 4-5 micron thickness of protective coating is removed from the surface.

There are no less important components in the chain of technological production of good anti-corrosive material. You cannot oversimplify the meaning of galvanizing” to the meaning of “paint with zinc content”. The essence of the effect mechanism is that liquid zinc is zinc in the form of paint, rather than paint with zinc. The meaning of the galvanizing effect is the electro-chemical contact between iron and zinc. If you add zinc powder to the paint, you get the paint spoiled with zinc powder. The contact between iron and zinc on the electro-chemical level will not occur, because the paint is dielectric (not-conducting the electric current). By the way, on the shelves of the building materials shops, it is quite often possible to find “zinc-rich” or “zinc-contained” paints, which are recommended by the producer for the anti-corrosive protection of the metal. Unfortunately, in the major cases, this information does not correspond to the reality and is cheating. In galvanizing the very important role is played by not only the quality of the zinc powder but also by the polymeric filler, in which it is placed. Polymeric filler should not be the obstacle for the electric current. We don’t want to disappoint you, but in order to obtain reliable anti-corrosive effect it is better to purchase proved specialized material. As an outcome, you shall save time and money and in addition get the desired result.

Neither first, nor second is not allowed to use for the purpose of reaching the working viscosity of Galvanol. Galvanol is sold in ready-to-work form; that means that to get started, you should only mix it thoroughly. If in the course of work the container with Galvanol stayed not tightly closed within a few days, bringing to the galvanizing thickening (evaporation of the solvent), then it is better to use xylene for the dilution of Galvanol. We would like to draw your attention to the need to purchase the high-quality solvent, which meets the state standards, from the reliable seller. In case of use of the poor quality solvent, the subsequent flaking and peeling of the zinc coating is possible.

Based on the extensive experience of the anti-corrosive coating Galvanol application, with great possibility it can be assumed that the reason of this situation lays in the small diameter of the nozzle (it is required to use nozzle with diameter 2 — 3 mm), as well as low pressure of your paint sprayer (recommended pressure is 0,2 — 0,3 mPa). This is the common situation when using domestic (not professional) painting equipment.

Galvanol comes in ready-to-use form. If necessary, to give the composition higher fluidity, you can use xylene, however, in order to preserve its performing characteristics it is desirable to add not more than 5 % of the total mass of the liquid zinc.

The most possible reason of detachment of the protective coating is poor preparation of the metal before galvanizing: poor metal cleaning, application of poor solvent for degreasing, etc.

The effectiveness of and hot galvanizing in principle does not differ; and this is proved by specific researches. The other point is, that hot galvanizing is the traditional technology, theoretically known to each person; and galvanizing so far is not widely known method of metal protection even for professionals. However, if you compare these two technologies more deeply, you can say, that galvanizing is the technology of anti-corrosive protection, which is now expanding the scope of its application and shall expand in the coming years due to its technological simplicity and cheapness; unlike the hot galvanizing is gradually decreasing its scope of use due to its technological complexity, energy consumption, ecological threats to the nature environment.

Zinc coating Galvanol is compatible with any lacquer-and-paint materials, including powder paints.p>

If you perform anti-corrosion protection of your car bottoms yourself, you need to understand that its effectiveness shall directly depend on the quality of the metal preparation. That means that the better you prepare the car bottoms, the longer and more efficiently the protective galvanized coating shall serve. Based on the years of experience, we can recommend you, first of all, to clean and dry the bottoms of the car very thoroughly. You should start the removal of the corrosion when the bottoms are clean and dry. The most convenient way to undertake the removal of the corrosion is using angle grinder with a metal cord. Preferably you should lift your car. Be patient and perseverant; you should understand that the quality of further anti-corrosive protection of car bottoms depends on this phase. After removing corrosion do not delay the process of galvanizing for more than two days, if the car stands in a dry place. After stripping to bare metal, don’t be lazy, degrease surface with xylene or solvent. Do not use other liquids for degreasing, because many of them remain film on the metal surface. You can perform anti-corrosive treatment of the car bottoms immediately after degreasing. If for some reason you decided to go without degreasing, you should necessary remove dust from the metal. The Galvanol layer dries very quickly; next layer is applicable after 30-40 minutes. If you are going to apply additional mechanical protection on the galvanized layer, let the last layer of liquid zinc to dry completely within 24 hours. Made with your own hands anticor (taking into account our recommendations regarding the usage of Galvanol), shall serve you for many years no worse than factorial performed anticor.

Typically, zinc coating after galvanizing does not have metallic gloss, it is matte. Sometimes this factor plays a decisive role in favor of choosing other ways of galvanizing (hot, plated, thermo-diffusion), even despite their significantly higher price. However, you can easily solve the problem of the matte structure of the coating by appying Alinol mixture. Alinol is specially designed decorative and protective coating, which ideally combines with mixtures for galvanizing and gives the metallic gloss to the galvanized metal. Alinol can be applied on the top of Galvanol already after 30 minutes. Its consumption is 150 mg2 with layer thickness of 40 µm. Layer dries within 30 – 40 minutes. Alinol application is available with temperature down to -35оС.

The reason for this situation, most probably, lays in the fact that when cleaning the metal you have polished it. The optimal way to clean the metal is sandblasting or bead blasting. After such a treatment metal is clean, but remains some roughness. In case if you use drill with cord attachments to clean the metal, then at high speed you reach the surface polishing, and the surface becomes too smooth for the high-quality contact with Galvanol. Therefore, in such cases, when you suddenly made polishing for providing the high quality contact between Galvanol and iron, we recommend to handle the metal surface with rough sandpaper.
