How to Choose the Right Paint Stripper
Before you begin your paint removing job, there are several things you have to consider to optimize your results. It is essential to note that not all paint strippers are suitable for all types of surfaces. Some strippers have harsh chemical components that could easily damage surfaces and require special safety precautions.
Know the Type of Surface
Before you make your purchase decision, consider the type of surface you want to strip. For instance, heat guns are ideal for surfaces with multiple layers of paints. They are also more suitable for metal surfaces. Sanders, on the other hand, is suitable for wooden and metal surfaces, while biochemical products are more suitable for metals and floors.
Large surfaces on immobile projects such as siding and baseboards, heat guns would be ideal. Floors made of hardwood and other pieces of furniture, sanding may be an ideal option.
Safety is always a priority when deciding on the ideal paint remover. Caustic paint strippers are very strong and effective, but they contain harmful substances such as methylene chloride.
Exposure to these chemicals could adversely affect your health. Long term exposure may lead to liver failure, kidney damage, and even cancer. These products should be used outdoors. Even when handling safer alternatives, you need to be cautious.
If you’re stripping surfaces painted before 1978, you might need a lead paint test kit. If the paint had lead, you would need to paint strippers suitable for such paints. These paint strippers come in a gel-like or paste form, and they are made to trap lead particles from escaping.
Types of Paint Remover Products
There are many types of paint strippers available in the market today. Each of these products possesses unique properties that make them more suitable in removing paints from specific surfaces. Similarly, certain paint strippers are more effective in removing long-lasting coatings such as polyurethane and epoxy on certain surfaces.
Chemical-based paint strippers can also pose significant health risks if mishandled. Handy tools, on the other hand, are reusable but can be quite exhausting in a large project. Whichever paint stripper you choose, always try testing it on a small area so that you don’t cause permanent damage to your item.
This category of paint removers is the most versatile, and they work by breaking down the bond between the surface and the paint through a chemical process. They are best in removing oil-based and water-based paints. Solvent-based strippers are also effective in stripping epoxy and polyurethane paintings from surfaces like metal and wood without causing discoloration.
Some brands of solvent-based strippers contain methylene chloride (DCM), which is classified as the volatile organic compound (VOC), while others include a mixture of toluene, alcohol, and methanol.
Products having a high concentration of VOC can affect your health if you inhale the fumes. Anyone directly inhaling the fumes of products containing methylene chloride may have their vital organs such as the reproductive system and brain-damaged. Therefore, when handling such products, always wear a respirator, skin covering clothes, safety glasses, and gloves made of resistant material.
Solvent-based strippers are used in a thin layer typically about 1/8 of an inch and stay briefly on the surfaces often about 10 minutes or less before the paint is lifted off with the scraper. Surfaces that have been stripped should be washed immediately with water or spirit before it is repainted.
Caustic strippers contain sodium hydroxide, an active ingredient that acts by partially converting the dried paint into soap and loosening it from the metal or wooden surfaces. These types of strippers are not suitable for epoxy and polyurethane. They are very effective in removing oil-based paints.
Although caustic strippers may be used to strip off water-based and oil-based paints from wooden and metallic surfaces, it can bring undesired results. Caustic strippers can quickly erode metals such as aluminum and cause discoloration of hardwoods such as maple. However, the black coloration can be removed using wood bleach.
Caustic strippers should be applied in a ⅛-inch to 1/4-inch contact layer and should last for about 30 minutes before scraping off the old paints. These paint strippers are alkaline, having a higher pH of between 13 and 14, the stripped surfaces should be neutralized so that the pH returns to about 7, and this is done by wiping with a vinegar solution or plain water.
Caustic strippers can irritate the skin, eyes, and lungs if you touch or inhale. Therefore working with these products needs ideal safety gear such as respirators, skin covering, safety glasses, and chemical resistant hand gloves. However, caustic strippers are safer compared to solvent-based strippers because they have low VOCs.
Compared to solvent and caustic strippers, biochemical strippers are much safer to handle because they are made from plant-based compounds like terpene and organic compounds like N-Methyl-2-pyrrolidone (NMP). However, the added organic compounds may cause skin irritation and even adversely affect the respiratory and reproductive systems.
Therefore when handling biochemical strippers, it is advisable to wear safety gear to protect yourself.
Biochemical strippers are effective in removing oil-based and water-based paint from metal and wood surfaces. However, they are not effective in removing epoxy and polyurethane coatings. After using biochemical strippers on wooden surfaces, they leave loose wood fibers on the stripped surface.
They should be applied in a thin layer of about 1/8 inch to 1/4 inch. It needs to remain on the surface for about 3 to 4 hours before the surface is scrapped. After applying biochemical strippers, the surfaces should be washed with mineral spirits or water, and there is no need to neutralize.
These paint removers are safe because they don’t contain methylene chloride, organic compounds, or Lye. This category of strippers is odorless and costly. They are manufactured using natural solvents such as benzyl alcohol. These strippers are effective in breaking down the resins of oil-based and water-based paints on metal surfaces and, to some extent, on wood surfaces.
Although they are the safest strippers, exposure may also irritate the skin and lungs, and therefore, you need to wear protective gear. Using Zero-VOC products require about ⅛-inch to ¼-inch thickness and should remain on the surface anywhere between three and 24 hours. After the paint is removed, you need to rinse the surface using water or spirit.
Other Types of Paint Strippers
Today, there is a wide range of machine tools used as paint strippers such as Belt sanders and drum sanders. Wood scrapers can be used, and they can yield excellent results, though they can easily bite into the surface of the wood and cause damage.
Heat can also be used as a paint stripper. Blow torch and heat guns are the tools that use heat to remove old paints. The blow torch uses a naked flame to strip paints off the surfaces. They have an adjustable knob used in controlling the intensity of the flame.
On the other hand, heat guns don’t use naked flames. These tools are suitable for metal surfaces, and if you’re handling them, you need to take extreme caution. Materials like wood and plastics can be damaged or catch fire. Professional training may be required before handling them.

Other General Safety Precautions
Paint stripper solvents and gels contain potentially hazardous chemicals. Each product has specific safety precautions given by the manufacturer. However, there are some general safety precautions that you need to keep in mind when dealing with any paint stripper.
- Always read and follow instructions on the label by the manufacturer. It is easy to assume you already know how to use a paint stripper when you have been doing it for a while.
- Ensure you wear chemical-resistant gloves. Gloves made with neoprene or butyl rubber are recommended. Besides, replace gloves often to minimize dermal exposure risk.
- Avoid using other products or chemicals not intended for paint stripping work like gasoline, kerosene, or lighter fluid.
- Avoid any type of paint stripping chemicals coming into contact with your eyes. You need to wear protective gear all the time.
- Don’t attempt to use a heat gun as a hairdryer, they might look similar, but they don’t work the same.
