Zinc white: application, characteristics, painting methods

Zinc white are inorganic pigments based on zinc oxide, which, in combination with various binders (linseed oil, vegetable oils), form white paints. Few people know about the characteristics and features of zinc white, so this article will focus on this substance.


In its pure form, the product is completely white with a slight bluish tinge. White is odorless, and can also be well mixed with an aqueous solution of alkali and ammonia. They are not destroyed or deformed under the influence of microorganisms and bacteria. Because they absorb moisture, they should only be stored in sealed containers.

Positive properties also include indicators such as:

  • low toxicity;
  • sunlight resistance;
  • easy to apply;
  • compatible with all kinds of paints;
  • weather resistant.

However, they also have negative properties, which include cracking, poor hiding power and the ability to absorb a large amount of oil.

When used in painting, such properties of white as brittleness and the ability to become covered with cracks,lead to the fact that the pictures painted with their use cannot be folded. And you also need to monitor the tension of the canvas, which changes with increasing humidity. When it is compressed or stretched, the white may crumble.

Types of zinc white

Zinc white is divided into two grades: BTs0 and BTs1.

The product belonging to the BTs0 brand is used for the manufacture of paints and varnishes, artificial leather and rubber products. It is also added to abrasive materials and cement compositions for dentistry.

BTs1 brand whitewash is mainly used for the manufacture of asbestos-cement and paint and varnish materials, which are used for interior and exterior decoration of premises, less often for the production of artificial leather and sole rubber.


Besides this, there are other areas where zinc white is used. Their use is in medicine. They are one of the components of some antiseptic ointments and powders. They are also used to make plastics, rubber, paper and glass.

Zinc white (white paint), made on the basis of grade A zinc oxide, can be distinguished separately. This paint is divided into several types intended for outdoor and indoor use. Among this type of paint, zinc white MA 22 is most often used for interior decoration, which are distinguished by high performance and increased fire safety.

Besides, building anti-corrosion paints are made from zinc white today.White is added to putties and various adhesives, and is also used in the manufacture of ceramics.

You should know that when carrying out repair work, zinc white, diluted with drying oil to a paint consistency, can be impregnated with linen strands, which are used as seals in threaded connections of water pipes.

For painting works, pure zinc white is produced, consisting of very fine particles of zinc oxide, not containing impurities of iron oxide and lead. They are translucent, have a cold tone and, when applied, form an inelastic film. They are used in all types of painting because they are very light-resistant pigment, which is not subject to change even in those paints that contain sulfur. They are usually whitened with cinnabar, and also added to cadmium to improve its quality.

Oil zinc white

Such a product is zinc white, which is rubbed with drying oil or vegetable oil. They are often called oil paints and are used to protect metal structures from corrosion, as well as to paint wooden and plastered surfaces. Moreover, they are suitable for outdoor and indoor use.

zinc white application

Zinc white oil has good hiding power, that is, when applied to the surface, they completely hide the color of the previously applied coating. In addition, after application, they create a durable anti-corrosion coating with high moisture resistance andvapor tight.

Painting method

Zinc white is used to cover plastered, metal and wooden surfaces.

The work is carried out by wearing rubber gloves, and during their implementation and after completion, the room must be ventilated.

Before you start painting, white, if it is a thickly grated powder, should be diluted with natural drying oil, the percentage of which should be 18–25% of the total mass of white, and stir very carefully. If it is an oil paint, then, if necessary, white spirit or turpentine is added to it.

Surface should be pre-prepared:

  • first it is cleaned of dirt, grease, dust and old paint (if required). This is done with a spatula;
  • then gaps and cracks are covered with putty;
  • after it dries, the work surface is polished using sandpaper;
  • then apply a primer;
  • after the primer dries, proceed to painting.

To reduce the consumption of white, it is recommended to cover the surface with drying oil.

Apply white to a dry, smooth surface with a paint brush, spray gun or roller:

  • brush is used for painting small elements and small surfaces;
  • use brush or roller for large areas;
  • more effectively the painting process takes place with the help of a paint sprayer. This method makes it possible to create an even layer and process hard-to-reach places.

The number of layers can be 1 or 2, depending on the desired result. Each layer usually dries overnight if the room temperature is not lower than + 20º C. The consumption of white for one layer is approximately 170–200 g per 1 sq. m.


Different options are used for packaging. Zinc white can be packaged in bags (polyethylene or paper), polyethylene or wooden barrels, cardboard or plywood containers with a polyethylene liner, paper or polyethylene bags, as well as in special soft disposable containers.

Transportation and storage

It is allowed to transport the product by all types of covered transport, with the exception of whites packed in special soft containers - they can be transported in open vehicles, as well as stored in open areas.
