Types Of Metal Paint Stripper
Solvents are a common yet versatile kind of paint stripper made up of strong chemicals that can break down the bonds of the paint on any surface. This type of paint stripper includes limonene (or other terpene solvents), n-methyl pyrrolidone, dibasic esters, aromatic hydrocarbons, and other solvents. However, the formula mainly required depends on the paint type and the composition of the underlying surface. Another commonly used solvent is nitromethane. If you’re looking for a less corrosive solvent, solutions using dimethyl sulfoxide are a great alternative.
Caustic paint removers, such as sodium hydroxide (also known as lye or caustic soda), break down the paint’s chemical bonds mainly through hydrolysis of the chain links of the polymers that make up the paint. Antique sellers who want to restore ancient furniture by removing aged varnishes, for example, frequently employ caustic aqueous solutions. Caustic paint strippers are alkaline and may interact with the paint on a chemical level, turning the paint into a soapy substance that makes it easy to remove paint from metal surfaces.
Biochemicals are another type of remover that is less harsh when compared to solvents and caustic strippers. It is a mix of plant-based solvents and organic compounds. However, it does not work with other types of paints that are not either water-based or oil-based. These kinds of solvents are great for DIY workers as it is safe to work indoors, but of course, taking precautions with chemicals is always crucial as you can never be too sure how it may affect you.
Zero-VOCs are the safest type of removers as they are made of natural solvents such as benzyl alcohol that have the least harmful effects. This type of paint stripper is much like biochemicals as it is safe to use indoors and for DIY projects. However, unlike the latter, it is much safer than biochemicals as it produces the least amount of toxic fumes in comparison.

How To Choose The Right Metal Paint Stripper?
Specific removers are less toxic than others, and hence it is safer to work on your own without outside help. Certain paint removers, such as solvents and caustic removers, work best as there is a shorter wait time for the paint to begin dissolving. However, they produce a lot of toxic fumes and can damage certain surfaces, depending on the type of metal the object is made of. It is also wise to remember while employing caustic paint removers, the chances of side effects and health hazards must also be considered as each type of paint remover has its pros and cons and depending on your needs and requirements. It is advised that you analyze the work you require the paint stripper for and make the purchase accordingly.
Just as there are different types of paint, there are different types of removers with varying application processes. For example, solvents are generally applied with thin layers and can be removed with a paint scraper. Caustic removers require a much thicker layer and are required to be applied for a longer duration in comparison to solvents (approximately 30 minutes or more). Biochemicals must be applied with thick layers, and due to their mild nature, they must be applied for anywhere between 3 to 4 hours. Low-VOC paint strippers need to be applied for a whole day with a thickness of 1/8th of an inch. You cannot use the same brush that you apply the remover with for painting, as these brushes are usually disposed of once used with a remover.
When using paint removers, you must always ensure the safety of yourself and any other individual or pet that may be around you. It is best to cordon off the area in which you will be using the remover and ensure the area is well ventilated. The fumes that some removers give off are toxic, especially the solvent removers and caustic removers. So it is also advised to equip yourself and whomever you may be working with personal protective equipment (PPE). The low-VOC paint strippers are ideal as they are the most environmentally friendly and the least hazardous and toxic form of paint remover. However, they do require 24hours to dissolve the bonds of the paint stain or droplets fully.
