How to clean exterior wall paint?

Exterior wall coatings are mostly viscous oily pigments with water resistance, which can be easily ignited if they are not completely dried. Soluble in alcohols, aldehydes and other chemicals, but also soluble in gasoline, diesel and other oily substances. So cleaning the exterior paint is very troublesome. Let's take a look at how to clean it.

Chemical cleaning. Strong solvent-based scavengers are effective for most oily paints and latex paints, primers, colorants and varnishes, while chemical scavengers can only be used for small areas with upward surfaces.

For old walls built with oily coatings, chemical treatment is usually used to remove exterior wall coatings. Like a strong solvent scavenger, it can effectively remove oily paint or primer, latex paint and so on. But the chemical removal is limited to a small area.

The concrete thin-layer cleaning agent can be used for cleaning the ash on glazed tiles, whole-body tiles, vitrified tiles, polished tiles, decorative tiles, clay products and natural stone villages at one time.

Most exterior wall coatings are water-based coatings. There is no special method to remove waterborne coatings. The most common way is to spray the wall with water and then remove it with tools such as shovel or scraper. There is no skill in this. In the process of uprooting, different shapes of scrapers can be used to scrape off the exterior wall paint at different corners. For parts that are difficult to disassemble, a wire brush or grinder can be used. Be very careful when using it to avoid injury.
