How to remove exterior wall paint, what to use to clean it off exterior wall paint

There are two ways to clean exterior paint, and they are: paint cleaner, and the gods serve gasoline or kerosene.

1. Use paint cleaning agent.

Paint cleaner is used to clean the surface of ceramic tiles, stones, glass and metal products, when in use, after cleaning the dust on the surface of the wall with water, put a brush in the solution to wipe it, and finally wash it with water. If glass or metal products can be scrubbed with the help of steel wool balls, paint cleaners can effectively remove paint from the surface without damaging the surface.

2. Use gasoline or kerosene to scrub.

If the exterior paint is solvent-based and gets on clothes, you can use a cotton cloth dipped in gasoline or kerosene to scrub to dissolve the paint, and then rub it to remove it, and then wash it again with detergent. It is recommended to dry in a cool and ventilated place to avoid sun exposure.

Selection of building exterior wall cleaners:

1. Acidic cleaners (such as oxalic acid, hydrofluoric acid, hydrochloric acid) have a quick effect on cleaning, but they are easy to burn the exterior wall and are not stain-resistant, and at the same time cause great harm to people, objects and the environment.

2. Alkaline cleaners (such as degreasers, wax removers, all-round cleaners) have a slow cleaning effect, but they will not damage the wall, and the harm to people, objects and the environment is small, so it is recommended to use less acid to clean the exterior wall, especially not to use strong acid.

With alkaline cleaners, it is recommended to use high-performance, high-concentration alkaline cleaners to clean the exterior walls, so that the cleaning effect will be greatly improved without damaging the exterior wall surface.

There are many types of paints, and exterior paints are one of them. Exterior wall paint is used to paint exterior walls and is a building decoration material, there are many types of this building decoration material, and it is also a building decoration material that is not easy to clean. Do you know how to clean exterior paint?

Exterior paints are more difficult to clean if they get on your hands or clothes, because most of them are insoluble in water. Let's take a look at how you calculate how to remove exterior paint? Let's learn about the use and development of exterior wall coatings.

First, the method of removal

Just use a detergent.

Second, the use

Paint is an ancient name; Coatings, which is a modern name, contain more technical components and are widely used in modern science and technology and industrial fields. However, there are some customary names for paint that are still retained, such as latex paint, primer, topcoat, etc. Generally speaking, a coating is a material that can be applied to the surface of the coated object and can form a continuous film that adheres firmly.

It can be both inorganic, such as electroplating copper, electroplating nickel, electrogalvanizing, etc. It can also be organic, such as most organic polymer materials, which constitute a major part of today's coatings market.

3. Development

Paint is a mixture of organic or inorganic materials used to decorate and protect items. The origin of the paint is inconclusive.

By 6000 BC, China had improved paints by roasting them with a mixture of inorganic compounds and organic pigments. In 1500 BC, in caves in France and Spain, paint was already used for painting and decoration.

In 1500 BC, the Egyptians used dyes such as indigo and madder to make blue and red pigments, but the paint was still far from perfect. In the 18th century, Nian Mingmeng developed the paint industry rapidly due to the development and utilization of linseed oil and zinc oxide. The 20th century saw significant developments in the paint process, with the emergence of paints in a variety of colors with greater adhesion, higher gloss, flame retardant, corrosion resistance, and high thermal stability.

In the early days, most of the paints used vegetable oil as the main raw material, so they were called "paints", such as healthy and environmentally friendly original tung oil. Whether it is the traditional coating products with natural substances as raw materials, or the coating products with synthetic chemical products as raw materials in the modern development, they all belong to organic chemical polymer materials, and the coating film formed belongs to the type of polymer compounds.

Generally speaking, exterior wall paint can be cleaned directly with some professional cleaning agents, most of the exterior wall paint is soluble in grease, when we find that our hands or clothes stick to the exterior wall paint, we can choose some oily substances to clean. Exterior wall paint has existed in ancient times, but now exterior wall paint contains more chemicals, and the damage to ** is also relatively large, so when we use exterior wall paint, it is best to wear gloves and do a good job of protection.
