Types of paint
The final exit of the building and its walls has a great effect that highlights the role of architecture and design intelligence – and it can be attractive and it can also be repulsive, depending on the degree to which the standards follow the finalization and directing of the building, this is represented in paints, materials and various decorations. And knowledge of the designer of all kinds. Let’s talk about Types of paint.
This article explains various types and types of paints, varnishes, ancient and advanced architectural paint, and their advantages to know how and where to use
Architectural varnish paint: among its types are emulsion paint: multiple types, among which are conventional water, such as lime, glue, dystemper, and plastic. There are also advanced types of water based paints, such as quartz, graffiti, and semi-glossy plastic. Limestone paint is one of the oldest and cheapest water-based paints, although its use is currently low due to the effect it has on hands and the body. Advanced, modern and fast types of water-based paints have appeared, such as plastic paint.
Lime paint is prepared by heating the lime stone or chalk, so the temperature of the stone rises and turns from calcium carbonate to calcium oxide, which is a limestone
The lime that is suitable for painting is the royal lime, which is made in special ovens (kilns). It is a solid piece of water that is poured into it to inflate and the temperature rises and is known as matte lime (calcium hydroxide). The lime must be completely fluffy. And the color dissolved in the water is added in quantity The occasion according to the desired color, and it is noted that the color opens a lot after drying, then add table salt (sodium chloride) in the following proportions
Salt in a ratio of 1: 30
Likeness in a ratio of 1:40
And the benefit of salt is to install lime on the walls. And lime is considered one of the health paints for buildings internally and externally.
Lime paint method:
1- Lime can be brushed, sprayed or sprayed with a manual or electric machine
2- In the case of brushing lime, the first side is painted in one direction, then the second side is painted in an orthogonal direction on the first face, after the first face is completely dry.
3- In the case of spray painting, the first face is sprayed, and after drying, the second face is sprayed perpendicular to the first face
4- Oxide colorants should not be used without lime alkalinity
5- The surface should be cleaned thoroughly before painting.
As for paint with glue, it is considered one of the low-cost paints as well, but it is more expensive than lime paint, it exceeds lime paint by giving it a smooth surface and better and clearer colors than lime paint, the surface must be prepared and cleaned well and any old paint is removed before starting to paint with glue
The glue paint is prepared from an appropriate amount of asbij (calcium carbonate), glue, water and colored oxides and left in the water for a period of between one to two days, then it is stirred well and filtered, then an appropriate amount of glue is soaked in water in a ratio of 1: 3 and wait until it is fully absorbed Then put it on a quiet fire and then add hot water until it is in the consistency of the plastic, then the colored oxides are prepared and then mixed with Asbijd and invoices are made for the colors and the required color is specified, noting that drought makes the color lighter, the glue used in this type of animal glue is available on Body panels a And liquid sheets.
Glue paint method:
The paint is brushed, so the first face is painted in one direction and after the dryness, the second face is painted in a vertical direction on the first face, in the case of spraying the first face must be in the direction and the second face is in a vertical direction on it, after the first face is completely dry with the need for movement The spray is circular
Of the old water-based paints and is in the form of a powder or liquid and there are two types of it the first for washing and the second is not washable, the non-washable type consists of animal glue with colored materials and appropriate water materials and then grinded well then added to it bentonite or methyl cellulose for ease of operation with the addition of preservatives As for the washable type of casein, then add an ammonia solution with adding 1% of potassium bicarbonate of casein weight, and this makes it washable, then add a spidag or zinc oxide in a ratio of 1: 8 of the casein, then add kaolin in a ratio of 2: 1 of the casein with the addition of methyl cellulose and This is then mixed and ground
Water-based paints, known as paint paints, are among the most recent types of paints, which have evolved considerably and have become competitive with all other types of paints, such as paint lacquers.
Reasons for the superiority of these paints:
1- Ease and speed of paint and speed of dryness
2- The possibility of obtaining colors of different degrees that cannot be obtained from any other type of paint
3- Creating shiny, semi-glossy, and washable types
4- Ease of manufacture and application
5- Cheap price as raw materials and factories
6- Easy cleaning and the possibility of painting a new face after a while
Kinds of plastic paints:
1- Matt plastic paints
2- Glossy plastic paints
3 semi-gloss plastic paints
Plastic paint components:
Plastic paints are included in many of the raw materials that have evolved considerably, such as: polymers and titanium dioxide, which give whiteness.
Steps to paint a plastic paint:
1- One of the important things for a good completion of any type of paints, whether architectural, industrial, insulating or varnishes is the preparation of the surface for this paint in the sense that good paint is accepted in its various stages, whether primers, pastes, bushings or different aspects of paints
2- For the success of the paint we must study the surface well or its compatibility with the layers of putty and paint and the importance of this appears in the old surfaces to be repainted
When wanting to paint an old surface painted with an oil or lacquered paint and required to paint it with a plastic paint, an intermediate layer should be made between them consisting of the matted lacquered paint after cleaning the surface thoroughly by making the necessary sanding
3- An important thing in the surface fittings for the plastic coating is the complete cleaning of this surface and the removal of any dust.
Surface preparation stages steps:
1- Full surface cleaning and good sanding and removing any dirt
2- The surface can be grinded with a diluted plastic face first, then spread a paste layer, depending on the engineer’s vision and the surface condition.
3- This is followed by sanding it after the paste layer has completely dried.
4- Good cleaning of the sanding product, then inventory the following putty or make the paste mixing only according to the surface condition
5- The layer of the lining or the first side of the plastic is painted and is 15% to 50% water softened according to the type and grease of the plastic and its ability to do so. It is preferable that this lining or the first face be colored with a color lighter than the required color
6- The second side paint layer is made less diluted than the first face in the range of 15% to 20%, depending on the type of plastic, its ability and grease. The plastic shall also be tinted with a lighter color than the required color, provided that after the second face is completely dry
7- In some types of luxurious finishes and super loki, a dry lacquer face is made as a layer between the paints of plastic, especially if the layers of paint are more than 4 layers.
8- After that, the necessary mixing is done with the plastic paste and then painting the good face with the required color according to the color bill approved
Among the newest types of plastic paints and the finest types of water based paints, it gives a good shape to compete with the lacquered paints, distinguished from its ease of painting and cleaning with the other advantages of plastic paints, with its strong resistance to water in addition to the wonderful aesthetic shape.
Among the modern practical paints that enjoy the beauty of appearance and multiple colors, modern and beautiful with ease of implementation and speed, and quartz painting does not need high expertise, one of its advantages is the possibility of painting it on all types of surfaces, whether precast concrete or prestressed or on the surfaces of asbestos boards, this paint gives a grainy shape Where it is painted on a sponge broth, and it can also be sprayed with spray paint machines or with compressors. New forms, squares and geometric shapes can be made on the surface, walls, or ceilings to be painted with quartz by applying the required drawing and discussions to the part that you want It is by using Solotype strips to show these subdivisions .. then paint and straighten.

Graffiti is one of the modern advanced claddings that solve many problems especially for different surfaces, whether cement, concrete, wood, or asbestos, as well as prefabricated and prestressed concrete surfaces, graffiti addresses the defects of the surfaces as it is spread with a thickness of 3 mm to 9 mm, thus covering the defects of the conch or brick Or concrete or other surfaces, such as wood or asbestos surfaces, similar to graffiti and quartz, but is composed of quartz granules, fine sand or calcium carbonate.
It is a common wall paint in most Arab countries and in European countries, and it is suitable for decorations, facades and entrances. Many types have been developed, granulite consists of breaking natural marble or from sand grains that are tinted by doco or epoxy and this is done in special mixers and then diluted
A type of granite has been developed consisting of colored round plastic beads. The size of granite granules ranges from 3 mm to 1.6 mm, despite the previous advantages of granite, but it needs special care when the individual and during the operation as it is not suitable on wet surfaces or with lime
Lacquers (oil paint):
Lacquer is one of the oil paints that has been used for a long time and has proven high efficiency and has a high durability for different weather conditions with the ability to wash, needs high experience in manufacturing or painting, and the surface to be painted with the lacquer needs special equipment
