Buyer’s Guide
Now that you have seen the top 6 paint strippers for concrete, you may be eager to jump the gun and purchase one immediately. However, there are some important factors to understand when looking for the best paint remover for concrete.
Read on to discover the different types of paint strippers available and how they work.
Different Types of Paint Strippers
As concrete is porous, it tends to absorb paint very quickly, making removing this paint very difficult. This is why some paint strippers are better than others when tackling this problem. These include:
- Liquid paint strippers (Solvent, caustic, and biochemical)
- Zero-VOC
Liquid paint strippers
This is the main type of paint stripper, including three categories; solvent, caustic, and biochemicals.
A solvent is generally the most versatile paint stripper. It uses chemicals to break down the bonds between the coats of paint and the surface. It works extremely well at removing oil-based and water-based paint from surfaces such as metal, wood, and masonry without discoloration.
One downside of using a solvent stripper is that it’s a highly volatile organic compound (VOC), meaning it is more hazardous to your health than others. They also have the strongest odors and fumes out of all paint strippers, but an advantage of using this type is that it is corrosive and ideal for heavy-duty paint removal.
Caustic paint strippers have the active ingredient of sodium hydroxide or lye. This helps convert dried paint into a soapy substance, making the paint lose from its surface. Caustic strippers are ideal for masonry surfaces like concrete and walls but not so good when working on epoxy, acrylic, or polyurethane.
You can use caustic strippers effectively on water and oil-based paints, while other paint types may become discolored. One disadvantage of using this type is that it tends to attract more moisture which can damage a wooden surface.
Biochemical paint remover is a more eco-friendly version when compared with the previous two options. There is very little odor with this paint stripper due to its natural ingredients. Although it has lower VOCs and fumes, it can still cause health hazards such as respiratory and reproductive issues and irritate the skin. This is why safety gear is essential when working with these paint removers.
This type of stripper removes oil and water-based paints from concrete and other surfaces. However, it isn’t the most efficient at stripping away paint as it usually takes quite a long time to activate and remove all of it.
Zero-VOC
Another type of paint stripper you can use is Zero-VOC. This doesn’t contain NMP, lye, or methylene chloride, making it one of the safest options. Nonetheless, it can still irritate your skin and lungs, so safety gear should always be worn when using this paint stripper.
It is practically odorless due to the use of naturally-occurring solvents in its makeup that break down oil and water-based paints to loosen them.
You can use Zero-VOC on metal, masonry, and wood occasionally. One downside is that removing epoxy or polyurethane isn’t very efficient.
It tends to be more expensive than other paint removers, but if you don’t like the idea of using more dangerous paint strippers, this may be the best option.
Heat
Aside from using chemicals to remove paint from concrete, other options exist, such as heat. If you use heat to strip away paint, you must do so cautiously. This is especially important for using a heat gun or a torch.
Both tools can become fire hazards and create toxic fumes. This is why many individuals prefer using a low-intensity infrared heater. Although these have limitations with how much paint they can remove, they are ideal for softening the paint so it can be scraped off easily.
Sanding
Another option to remove paint from concrete is by sanding. This can be done through the use of a machine or by hand. This process removes paint from surfaces through friction and can be very effective on smaller areas of singular coats of paint.
However, you should be careful when using this method as sandpaper can be intrusive, possibly resulting in some surface layers being stripped away too.
Power washing
Power washing can be a great way of stripping paint from concrete and other exterior surfaces. Again, you must be very careful when using a power washer, as operating can be challenging.
If you choose the wrong pressure amount, you could easily damage a surface, so ensure you know the correct amount of pressure beforehand.
Lead paint test kits
Whichever method you use to remove paint, you must determine whether the paint is lead-based or not. If it is lead-based, paint stripping creates dust that can easily be inhaled, absorbed, or ingested, leading to lead poisoning and possible death.
You can use a lead paint test kit to know whether the paint is safe to strip off immediately. If you are working on a larger scale, you should consider buying these kits in bulk, as the basic kit won’t be big enough to test all areas.
Frequently Asked Questions
Can you use a paint thinner to remove paint from concrete?
Paint thinners are quite effective at removing paint from concrete. Just like paint strippers, the thinner works by breaking down or thinning the paint before it becomes loose to peel off.
Such paint thinners are solvent which is good at dissolving substances like paints and works as effectively as acetone, turpentine, denatured alcohol, and more.
Can baking soda remove paint from concrete?
If your concrete surface has stubborn, dry paint covering it, baking soda and industrial bicarbonate work well at cleaning it away.
The best way to do this is to use a soda blaster to blast the solution onto the desired area to remove the paint.
Can you remove acrylic from concrete?
As acrylic paint is water-based, removing it from concrete and most surfaces is possible.
Removing acrylic paint from concrete is considered easier to remove than other paints, so you shouldn’t have a problem.
