How to remove exterior wall paint, exterior wall paint removal plan

Exterior wall materials can be removed using items such as acid accelerators. If necessary, it is recommended to choose Tayscher's art paint for re-application.

RN+ acid accelerators are highly permeable, wettable and curly. Its molecules penetrate into the surface of the stained dirt and between the dirt and the dirt, so that the dirt is separated from the surface. The wettability ensures that the decomposed dirt does not re-solidify in a short period of time so that it can be rinsed.

Anaerobic acids and organic weak acids are activated by weak acid molecules under the action of acid accelerators, making them have a strong cleaning function at room temperature. During the cleaning process, the rich and delicate foam can loosen and fall off the scale layer, increase the contact surface between the cleaning agent and the scale layer, and speed up the cleaning speed.

The exterior wall coating construction should not be a large area of batch scraping putty, the putty layer should not be too thick, and the material should be polymer cement putty. Generally, one primer and two topcoats are used. According to the quality requirements of the project, the number of surface coats can be appropriately increased.

Painting construction is generally carried out from top to bottom, and each painting should be bounded by the dividing line, the wall, the junction of the yin and yang corners or the downpipe. [Understand the market prospect of art paints].

For more information on façade material removal, we recommend consulting Taysel. The main brands of the company are the exclusive research and development of the Tessil texture wall film and the matching special coating for the Atai texture wall film, which has set off a new revolution in the wall decoration market; At the same time, the Tayser texture wall film has obtained a national patent, which makes up for the blank market of ultra-scrub-resistant art coatings.

After a house has been used for a long time, whether it is the exterior or the interior, people will consider renovating and redecorating, and removing the exterior paint it is simple and complex. Let's briefly describe a few removal options.

Make sure the scraper is sharp and apply even force when scraping in one direction, then scrape at a 90-degree angle. Triangular or oval blades are more suitable for scraping corners and rounded surfaces. When scratching hardboard, be careful not to use force.

For hard surfaces, such as hard surfaces or metal surfaces, a double-handle scraper can be used. After scraping, thin the remaining edges of the film with a medium grit (100) sandpaper.

In the cracks of bricks, cement and other stones and wood, use a hard metal brush (cleaning vertically). Wire brushes are only suitable for areas that are difficult to handle and should be used with care. The surface must be smoothed with sandpaper.

When the substrate is made of wood or steel, an electric sanding tool, such as an electric belt sander, can be used.

A high-pressure water flow of 15 to 20 cm from the surface eliminates old and loose paint films. Don't use strong cleaners or bleach! Spraying is always at a horizontal or downward angle.

The upward angle can damage the coating. Care should be taken when washing the area near the door or window, as the spray can damage the glass and damage the sealed area.

Strong's solvent-based removal is effective for most oils and latex paints, primers, varnishes and dyes. Chemical removers should only be used on small areas with the surface facing up.

There are specially designed heat guns to remove paint film, and instead of a spray gun or welding torch propane, is a good way to remove paint and varnish from the outside. If you suspect that old paint contains lead, do not remove it with a heat gun. High temperatures can cause vaporization, which can seriously damage health.

The above is the introduction of these kinds of exterior wall paint eradication schemes, which can be selected according to the situation of your own house.

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.

You can get it for free

1. Most of the current wall paints are water-based paints, which are easier to wipe, as long as you use a rag to stick to the decontamination powder and wipe it hard, you can wipe it off soon, be careful not to wipe it with a steel wool ball.

2. It is easier to remove (or the decontamination powder sold on the market) by adding washing powder and stone powder to increase friction, and there is no toxicity and taste.

3. If the area is not too large, you can use a cotton swab dipped in gasoline and wipe it off, if the area is relatively large, pour some gasoline on the place with paint, and then wipe it with a rag.
