Galvanized metal at home

What is a cold galvanizing?

Under this name disappeared very affordable way to enhance the protective zinc layer on the sheets or articles made of galvanized metal.In fact, this painting of metal, but the feature lies in the composition of the dye.

Tsinkonapolennye paint designed specifically for this purpose - to protect the metal and prolong its service life.As a part of each of them contains about 89-93% of the zinc powder, therefore the polymer is able to perform the same tasks as the hot, electroplating and other industrial galvanizing.But, in contrast, keeps cold galvanizing on the product up to three times longer, and addition of protective, has a decorative effect.

The only disadvantage of this method - polymeric layer sensitive to mechanical damage, so it must be applied carefully and evenly, and the operation in a timely manner to repair damaged areas.

How to paint galvanized roof or fence?

most frequent use of galvanized sheet steel in the home - the roof, and a variety of fences.Metal lightweight, inexpensive and durable, so it is popular in this area of ​​application is justified.

Those and other structures have similar characteristics: a large flat areas, the minimum elevation and angle, and therefore produce cold galvanized fence and the roof of one instruction:

1. necessary to prepare the surface before painting: clear it of debris anddust, remove the old paint if it was available.
2. Wash metal under the pressure of the water or detergent.
3. thoroughly dry.Unacceptable even the slightest traces of moisture or condensation.
4. If desired, clean and dry surface, you can apply a primer - a dedicated, contain zinc.It will enhance the effect of cold galvanizing, increase adhesion and reduce ink consumption.If using a ground enamel 3-in-1, the base coat is needed.
   
5. After the primer has dried, if you have not passed this step, a uniform thin layer of paint is applied tsinkonapolnennaya.If you use a spray, the coating will be faster if a roller and brush, the roller paint the flat areas and brush corners, seams and protruding elements.
6. not earlier than one hour, preferably after drying, apply the first layer is similar to the second.Make sure that there are no missed areas.
7. previous item, repeat if necessary.

After drying, cold galvanizing, a uniform polymer layer, which may at times increase the time of operation of the roof, fence or other metal from galvanized and ferrous metals.

How to make a car galvanized

galvanized parts of the car is much more complicated, and yet galvanized bodywork and other elements is also possible to make at home.

This requires consumables - chloride, zinc sulfate or zinc salts.It can be prepared with their own hands, by dissolving zinc in sulfuric or hydrochloric acid, or buy ready-made solder acid on the radio.

Galvanized Touring Car parts at home: a step by step guide.

1. 400-450 g of zinc put in acid resistance capacity and gradually add a thin stream of acid.Will the reaction solution and gradually becomes transparent.
2. item should be cleaned of dirt and grease.
3. For details, which requires galvanizing, you need to connect the "minus" from the normal charger or battery.
4. To connect a piece of zinc "plus".
5. energized.If training is done properly, the steel begins to visibly coated zinc layer.In case of failure, will form a loose dark coat.
6. At the end of the remnants of acid galvanizing process parts wash with running water or a weak solution of soda.

Sometimes a repair is necessary only to a small portion of the body, and the whole process is inappropriate item.In this case, you can make the most of the galvanized section separately.

• plot sanded and sanded sandpaper.
• «Plus" is connected to a piece of zinc.
• «Less" by the battery clip is connected to the body.
• piece of zinc is wrapped with a cloth dampened with a solution, as in the previous method.
• Zinc is necessary to smoothly drive on the cleared site periodically smachavaya cloth in the solution.Gradually, the metal will settle in the area of ​​the body.
• At the end of the galvanizing section also washed with water or a weak solution of baking soda to remove any residual acid.

Without this treatment, any body repair leaves the metal vulnerable to the external environment, and the paint will not be a full barrier.But after such a domestic galvanizing body of the car can safely be primed and painted.
