Considerations When Choosing a Paint Remover for Wood

Types of Paint Stripper

Caustic

Super popular, but less versatile, caustic formulas use lye to turn the paint it is removing into soap, which makes it super easy to take off a wood surface. However, you should use a caustic paint stripper on epoxy, but it will work well when used on oil-based paint that is on a concrete surface.

Solvent

Solvents are popular since you can use them for other purposes besides stripping paint. This chemical-filled formula is designed to separate paint from wood. Capable of working on both metal and wood surfaces, this formula will remove both water and oil-based paints pretty effectively. Keep in mind that solvents tend to have pretty strong fumes thanks to the VOCs, or volatile organic compounds, that are included in their formula. Make sure to wear a mask when you use this type of paint stripper.

NMP

NMP stands for N-methyl-2-pyrrolidone, which is a substitute to methylene chloride. This chemical is thought by some to be safer than methylene chloride, but there is still some debate on it.

Biochemical

If you are looking for a more natural option, biochemical formulas use more ingredients that are sourced from actual plants. Keep in mind that these formulas can still cause irritations and some brands will also use NMP in this formula.

Zero-VOC

This type of formula tends to be more expensive, but safer to use. Using alternative ingredients to NMPs or VOC and any other dangerous chemical, this type of formula isn’t that effective and can cause its own irritants.

Step by Step Guide on How to Safely Strip Paint from Wood

Making paint and varnish easy to remove, a paint stripper is a solvent that will soften old finishes. You can find them as a paste, liquid, or gel, and they are effective when you need to remove paint off of wood on a large project, fine details, or curved shapes. Also, you will find that paint strippers that are used on tight areas and rounded surfaces are more effective and easier than sanding.

How to Strip Paint from Wood

You can easily learn how to strip paint from wood using paint strippers and removers. Just remember that it’s important to keep the stripper and removers away from your lungs, skin, and eyes. Depending on the brand, you may be able to find a formula that has minimal odor and fumes that are also easy to clean up with just water. No matter what formula you get, it’s recommended that you use a paint stripper outside or in an area that is well-ventilated with drop cloths since paint removing is messy and smelly work.  It is also possible to use a hand engraving tool or dremel to remove paint from hard to reach grooves.

  1. • Using a metal or glass container, pour a little bit of the paint stripper into the container and then apply the formula as specified by the manufacturer.
  2. • If you are removing paint from a vertical surface like a wood door frame, use a paste or gel.
  3. • Start removing paint at the top of the project and then work your way down.
  4. • Make sure you take the time to work the paint remover into any hard to reach areas.
  5. • Give the solvent enough time to work according to the manufacturer’s instructions.
  6. • Being careful not to damage the wood, and use a putty knife, specialty scraper, or paint scraper to take off any softened paint.
  7. • If you encounter problem areas or are working on a detailed spot, reapply the paint stripper as necessary.
  8. • Use an abrasive pad or nylon brush to scrub the wood to get rid of stripper sludge and any traces of the old paint finish.

Features to Look for in a Paint Remover for Wood

If you aren’t sure what other surfaces you will work on next, it can be helpful to buy a multi-surface paint remover that you can apply to several different surfaces. A general paint stripper has the additional benefit that it can remove paint from many different surfaces, just make sure that one of those surfaces is wood.  Using the best paint remover for items like wood, metal, aluminum, and concrete is critical for a successful paint job.

For those that don’t want to waste a lot of time, look for a paint stripper that will work in just a few minutes. There are many on the market that can work quickly so that you can remove a layer of paint in about 15 minutes. Just make sure that you find out what chemicals these formulas use for the safety of those living in the house.

Strips Multiple Paint Types

Since water and oil-based paint can react differently to the same paint remover, it is important to make sure that the paint remover you choose will work on both types of paint. There are also some paint removers that are able to work on any type of paint or varnish, which can make the process a whole lot easier.

Avoid Methylene Chloride

If possible, avoid a paint remover that has hazardous chemicals in it like methylene chloride. Since it is pretty common, this can be hard, but it’s worth doing a little extra research to find a product that is safer to use. If you do choose a product that contains this chemical, make sure that you find out how to apply it to surfaces safely.

Test Older Paint for Lead
