Understanding Varnish
Before we dive into the process of stripping varnish off wood furniture and wooden doors, it’s important to understand what varnish is. Varnish is a clear or tinted liquid finish that is commonly used to protect and enhance the beauty of wooden surfaces. It can be made with different materials like polyurethane, shellac, or lacquer.
Varnishes are generally applied by applying many thin coats that finally make a very strong and long-lasting protective coating. Over time, varnish may become damaged or dulled from sun exposure, humidity, or tear and wear. This is when it becomes necessary to strip off the old varnish and apply a fresh coat for a renewed look.
Tools and Materials
To remove varnish off wood successfully, you will need the following tools and materials:
- Chemical stripper
- Protective (gloves, goggles, mask)
- Scraper or putty knife
- Steel wool or sandpaper
- Clean rags or old towels
- Mineral spirits or denatured alcohol

How to Strip Varnish Off Wood? Step-by-Step Guide
Sanding or Scraping
The first step in stripping varnish off wood is to remove any loose or bubbling varnish using a scraper or putty knife. This will help the chemical stripper penetrate through the varnish layers more easily. You can also use sandpaper or steel wool to sand down any rough areas and create a smooth surface.
Heat Gun Method
If you prefer a faster and more intense method of varnish removal, you can use a heat gun. This tool uses high temperatures to soften the varnish, making it simpler to scrape off. However, to remove varnish from wood with a heat gun requires caution and the right protective tools as the heat gun may be risky if not used correctly.
Varnish Remover
Chemical strippers are the most popular and effective method to strip varnish from wood furniture. They do this by making the varnish dissolve which makes it easy to take out with a scraper or steel wool. If you are applying a chemical stripper, pay attention to the instructions on the product label and use appropriate safety gear.
Steps to Remove Varnish with chemical strippers
- Prepare the work area by laying down drop cloths or plastic sheeting to protect your floors and furniture.
- Put on protective gear such as gloves, goggles, and a mask.
- Apply the stripper using a brush or cloth, following the instructions on the product.
- Wait for the recommended time for the stripper to dissolve the varnish (usually 15-20 minutes).
- Once the varnish has softened, use a scraper or steel wool to remove it.
- Repeat steps 3-5 until all varnish is removed.
- Wipe down the surface with mineral spirits or denatured alcohol to take away any remaining residue.
- Allow the wood to dry completely before moving on to the next step.
- Lightly sand the wood to even out any rough spots or remnants of varnish.
- Wipe down the surface again with a clean rag or old towel for proper cleaning of wooden doors and furniture and remove any dust.
Tips and Tricks
- Wear protective gear at all times when handling chemical strippers or using a heat gun.
- Work in a properly ventilated place to avoid inhaling fumes from the stripper.
- Test the stripper on a small, inconspicuous area before applying it to the entire surface.
- Use caution and apply gentle pressure when scraping off varnish to avoid damaging the wood underneath.
- When working with intricate or curved surfaces, use a toothbrush or steel wool instead of a scraper for better control.
- If using a heat gun, keep it moving at all times to avoid burning the wood.
