The Best Paint Strippers For Wood (Ultimate Guide)
Whether you’re looking to restore a piece of furniture, wooden molding, or another type of woodwork, you’ll likely find yourself needing to strip down the pre-existing layers of paint. As with any other paint job, the initial preparation is the most important step. In fact, the condition of the painting surface heavily determines the quality of the finish once you’ve completed painting.
If you have layers of paint on your wood surface that is flaking, peeling, bubbling, crackling, or chalking, no matter how many new coats of paint you apply you will not be able to remedy these issues. To avoid a subpar finish, it is always recommended to remove paint from the wood prior to applying any fresh coats.
The best paint strippers for wood are solvent-based, biochemical, Varnish Stripping Gel, and caustic paint strippers with lye. Biochemical paint strippers are great because they remove paint from wood, stone, and metal. Solvent-based paint strippers are great because they remove several types of paint and can also dissolve epoxy.
Types of Paint Strippers
When you break them down, you have four main types of paint strippers. Each type has its own unique properties that indicate whether or not they work at removing particular finishes from various surfaces, including wood.
Solvent Paint Strippers
Strippers that rely on chemical solvents to loosen up the bond between surface and coats of paint are the most versatile in the bunch. Solvent-based strippers are very effective at removing both water- and oil-based paints, in addition to long-lasting synthetic coatings such as epoxy and polyurethane, from wood surfaces. As an added benefit, they are also able to strip paint without resulting in any discoloration.
Many of these types of strippers contain methylene chloride, which has a notoriously high volatile organic compound (VOC) content. Others you’ll find contain ingredients such as acetone, methanol, toluene, and ketone. Products with a higher number of VOCs have more potent fumes and are also considered to be more dangerous to your health than other strippers.
You should always wear a respirator (in addition to long-sleeve clothing, chemical-resistant gloves, and protective eyewear) when working with solvent strippers, as inhaling the fumes has been linked to reproductive and brain damage. To avoid any potentially harmful effects on your health and the environment, you can opt to avoid solvent strippers all together and go with another option.
Thankfully, these types of strippers only need to be applied in a thin layer to work their magic. They often rest on the surface of the wood for up to fifteen minutes and then the paint is easily scraped off with a paint scraper.
Caustic Paint Strippers
These types of strippers contain lye, or sodium hydroxides, as the active ingredient for removing pain. Caustic strippers eat away at the paint by turning it into a soap that is then loosened and washed away from the surface. They are most effective at removing oil-based paint off of masonry surfaces like brick fireplaces and concrete flooring.
While they can remove both oil- and water-based paints from some wood surfaces, they are known to blacken hardwoods, such as maple. However, this darkness can be easily removed by using a wood bleach product. Though caustic paint strippers are safer than the solvent variety, it’s important to note that their alkalinity may tamper with the natural tone of your wood.
They are lower in VOCs than solvent strippers but can still cause irritation to the skin, eyes, and lungs. Be sure to wear the appropriate protective gear when you’re working with these types of strippers.
Biochemical Paint Strippers
When compared directly with the aforementioned paint strippers, biochemical strippers are a safer alternative. Made of a combination of plant-based solvents such as terpenes (found in citrus rinds and pine trees) and the organic compound N-methyl-2-pyrrolidone (NMP), they offer lower fumes and VOCs.
Although these strippers are safer to use, they can still cause irritation of the skin and adverse reactions to your respiratory and/or reproductive systems. Because of this, always wear chemical-resistant gloves, a respirator, and long-sleeve clothing when you’re working with biochemical paint strippers.
Biochemical strippers are a safe and effective choice for removing oil- and water-based paint from wood, metal, and masonry surfaces. However, in some cases, they can deposit loose wood fibers on the surface of stripped wood.
As far as application goes, these strippers need to be applied in a thick layer and sit on the surface for several hours before they can be removed. A fact that could be a disadvantage if you’re under a time constraint or want to finish your project quickly.
Zero-VOC Paint Strippers
If you’re especially concerned about your health and want to avoid the paint stripper choices listed above, you can opt for a paint remover that is VOC-free. These strippers do not contain NMP, lye, or methylene chloride and are virtually odorless.
Although they are pricier than other strippers, they are made of naturally occurring solvents such as benzyl alcohol that work to break down the resins of water- and oil-based paints. They are effective at removing these types of paints from metal, and masonry, but slightly less effective on wood. While VOC-free paint strippers can work on wood, they may require more time and effort to achieve the desired results.
