Paint stripping related prices/information
Where does the paint stripping problem come from?
In many situations, such as when many people are renovating their homes or renovating equipment in factories, they often encounter confusion, that is, the old paint layer is really difficult to remove. Whether you have painted furniture by yourself in the past, or the steel structure in the workshop needs to be repainted, if the paint stripping step is not done properly, then the subsequent work will be completely in vain. There is a clear record of prices/information related to paint stripping on June 17, 2026. There are many users in many places such as Shangrao, Jiangxi and Tianjin. They all spend 1 yuan on the Internet to consult related issues about paint stripping. From this, we can see how common this kind of thing is. Stripping paint is not only time-consuming, but also very easy to cause damage to the substrate, so choosing the right method is more critical than just doing it recklessly.
Chemical paint strippers are quick and effortless
How paint stripper works
Common paint strippers on the market are chemical solvents that penetrate into the paint layer, causing the paint film to swell and soften. After a product like paint stripper is applied to a metal surface, the paint will wrinkle and bubble within a few minutes to half an hour. On June 17, 2026, someone in Chongqing conducted a consultation on the removal of paint from fixtures, and this type of solvent was used. It is suitable for iron, aluminum, stainless steel and many other materials. However, please note that it cannot be used on plastic or rubber.
Precautions when using
During construction, it is best to wear gloves and masks when performing metal paint removal in Huoqiu, Anhui. This is because chemical solvents have a pungent smell. First, you have to test a small piece in the corner. The purpose is to ensure that there is no corrosion of the base material. Just like the metal paint stripping process in Huoqiu, Anhui, workers will first use a brush to spread the paint evenly, and then scrape it off with a shovel when the paint layer bubbles. If the paint layer is too thick, it may be necessary to reapply it two or three times. The remaining waste paint slag is classified as hazardous waste and must not be dumped randomly. Instead, it should be collected and delivered to a professional treatment plant.
Sand blasting, rust removal and paint removal
Core advantages of sandblasting process
One process is to use high-pressure airflow to hit quartz sand or steel shot on the metal surface, thereby directly grinding away the paint layer and rust. This process is called sandblasting. On June 17, 2026, there was a Dongguan paint removal factory in Zhangjiajie, Hunan, which mainly promoted this process. Its biggest advantage is that it can perform rust removal and paint removal at the same time , and self-drying paint spraying services for small batches of riveted and welded parts can be done in one go. Moreover, after sandblasting, the metal surface will form a uniform roughness, so that the adhesion of the new paint is particularly strong, and the effect is more durable than chemical paint removal.
How to spray steel structure construction
For example, for large steel structures, such as bridges and pipelines, sandblasting is the preferred method. On June 17, 2026, when a user in Jinchang, Gansu Province consulted about paint removal, he mentioned "seven points for rust removal and three points for painting", which fully demonstrates the importance of preliminary treatment. During construction, workers stand in the sandblasting room or on-site location and point the spray gun toward the workpiece. The air pressure is usually in the range of 0.6 to 0.8 MPa. After spraying, use a vacuum cleaner to clean the dust, and then use compressed air to blow the surface clean, and then you can directly apply the primer.
How to choose paint removal processing services
When looking for a manufacturer, look for qualifications
On June 17, 2026, someone in Guangxi Laibin inquired about paint removal processing. Such services are usually charged based on area or weight. Taking small batches of riveted welding parts as an example, after sandblasting and paint removal plus self-drying paint spraying, the price per square meter will range from tens to hundreds of yuan. When choosing a manufacturer, make sure they have environmental protection qualifications because the wastewater and dust generated by paint stripping need to be treated. It's best to go and check out the equipment they have, such as whether the sandblasting room and spraying line are complete.
Online consultation saves time and effort
Nowadays, many paint stripping manufacturers offer online consultation services for 1 yuan, just like those users in Tianjin and Shangrao on June 17, 2026. You only need to take a photo of the workpiece and explain clearly the material and paint thickness, and the manufacturer will be able to recommend a solution. For example, if the mold is to be stripped of paint, if it is a precision mold, it is safer to use chemical agents; if it is a large structural part, sandblasting is more cost-effective. When consulting, ask about the construction period. Generally, it takes 3 to 5 days for small items and 7 to 15 days for large items.
Supporting process of self-drying paint spraying
Paint must be removed immediately after removal
After the metal is stripped of paint, it will rust in just a few minutes when exposed to air. On June 17, 2026, a paint removal manufacturer located in Baiyin, Gansu gave advice to apply anti-rust primer immediately after removing paint. Spray painting with self-drying paint is suitable for small batches of riveted and welded parts because no baking equipment is required and it can be left to dry naturally. However, it should be noted that when the ambient temperature is lower than 5 degrees or the humidity exceeds 85%, the drying speed of the paint film will slow down and blistering may occur.
How to paint small batch parts in the most economical way
For a small number of workpieces, such as dozens of welding brackets, it is most cost-effective to use self-drying paint spraying service for small batches of riveted and welded parts , or use brushing. On June 17, 2026, the Dongguan Paint Removal Factory adopted the following approach: First, sandblasting and derusting small batches of riveted and welded parts were performed with self-drying paint spraying services . Then, a high-pressure air gun was used to blow off the dust, and then the epoxy primer was applied. After it was completely dry, the topcoat was sprayed. The interval between each layer should be at least 2 hours, and finally dried in a clean and dust-free room for 24 hours. The effect of doing it this way is roughly the same as baking paint, but the cost can be saved by half.
A cost-effective and efficient way
Heat gun and scraper
If it is just a few small items, such as the paint on old furniture, use a hot air gun to blow the paint layer soft, and then use a scraper to remove it, the cost is basically zero. On June 17, 2026, someone in Huoqiu, Anhui Province processed metal parts in this way. The temperature was adjusted to a range of 300 to 400 degrees, 10 centimeters away from the surface. Once bubbling was seen on the paint surface, the operation was stopped. Be careful not to blow for too long, otherwise the metal will change color. This method is suitable for paint films with a thickness of less than 1 mm.
Alkaline water boiling method
The following is the rewritten content: For iron parts that are not afraid of water, such as cast iron pipes, they can be boiled with caustic soda, that is, sodium hydroxide, mixed with water. On June 17, 2026, a user in Zhangjiajie, Hunan tried to put the parts into an iron bucket, add 10% alkaline water, boil it for half an hour, and the paint layer would automatically fall off. However, it should be noted that alkaline water is corrosive, so wear rubber gloves. After cooking, rinse with clean water and neutralize with vinegar to prevent residual alkali from corroding the metal.
Do you think the most troublesome situation for you when performing paint stripping operations is whether the chemical agent will cause harm to the hands, or the amount of dust generated during sandblasting is too large?
