Make sure to get a brush for applying the stripper. Safety goggles are also important to protect your eyes. Ensure you have a ventilated workspace to avoid inhaling fumes.
Ensure Safety
Wear protective gloves and safety goggles. This keeps your hands and eyes safe. Work in a well-ventilated area. Open windows or use a fan. This helps avoid breathing in harmful fumes. Keep a first aid kit nearby. Always read the instructions on the paint stripper. Follow them carefully for the best results.

Choosing The Right Method
Chemical strippers are fast and effective. They dissolve the poly. Apply with a brush. Wait for the chemical to work. Scrape off the softened poly. Use a plastic scraper. Wear gloves and safety goggles. Work in a well-ventilated area.
Sanding is a manual method. Use sandpaper or a power sander. Start with coarse grit. Remove the poly layer. Finish with fine grit for smooth wood. Be patient and thorough. Sand in the direction of the wood grain. This prevents scratches.
Heat guns use hot air. Heat the poly until it softens. Scrape it off with a putty knife. Careful not to burn the wood. Keep the heat gun moving. Use low heat settings. Wear protective gloves and goggles.
Using Chemical Strippers
Wear gloves and a mask for safety. Apply the chemical stripper evenly on the wood. Use a brush to spread it out. Wait for the stripper to work. This can take several minutes. The poly will start to bubble and lift.
Use a plastic scraper to remove the poly. Be gentle to avoid damage to the wood. Scrape in the direction of the wood grain. Remove all the loosened poly.
Wipe the wood with a damp cloth. This will remove any leftover stripper and poly. Let the wood dry completely. Check for any remaining residue. Repeat the process if needed.

Sanding Techniques
Removing poly from wood requires effective sanding techniques. Start with coarse-grit sandpaper, then switch to finer grits for a smooth finish. Ensure even pressure to avoid damaging the wood.
Select Sandpaper Grit
Start with coarse sandpaper
Proper Sanding Method
Always sand with the grain. This prevents scratches. Move in steady strokes. Never press too hard. This can damage the wood. Keep the sandpaper flat. Avoid tilting. Tilted sandpaper can gouge the wood. Sand all areas evenly. This ensures a smooth finish.
Finishing Touches
Clean the surface after sanding. Use a vacuum or cloth. Remove all dust. Dust affects the finish. Inspect the wood closely. Look for any rough spots. Sand these areas again. Apply wood conditioner. This prepares the wood for stain. The conditioner helps the stain go on evenly.
Heat Gun Method
Use a heat gun to warm the poly on the wood. Move the gun slowly over the surface. Do not hold it in one spot for too long. This prevents burning the wood. The poly will start to bubble and lift.
After heating, use a scraper to remove the poly. Gently scrape in the direction of the wood grain. Be careful not to damage the wood. Work in small sections for better control.
Wear protective gear like gloves and goggles. Work in a well-ventilated area. Keep a fire extinguisher nearby. Never leave the heat gun unattended. Follow the manufacturer’s instructions for safe use.
Dealing With Stubborn Poly
Thick layers of poly can be tough to remove. Apply a second coat of remover if the first coat did not work. Let it sit for a few minutes. Check the wood after scraping. Repeat if needed.
Some tools work better than others. Sandpaper can help. Use a scraper for small areas. Try a heat gun on thick poly. Be careful with heat. Chemical strippers work too. Choose the best tool for your job.
Post-removal Care
After removing poly, the wood needs care. Start by cleaning the surface. Use a soft cloth. Gently wipe away dust and residue. Let the wood dry completely. Apply a wood conditioner. This helps the wood absorb stain evenly. Choose a conditioner suitable for your wood type. Follow the instructions on the label. Allow the conditioner to penetrate. This process usually takes 15-30 minutes. Wipe off any excess conditioner. Now, the wood is ready for staining or sealing.
Sealing protects the wood from damage. Choose a high-quality wood sealer. Apply it with a clean brush. Use smooth, even strokes. Make sure to cover all surfaces. Allow the sealer to dry as per instructions. Usually, it takes 24 hours. Apply a second coat if needed. This ensures maximum protection. Sand lightly between coats for a smooth finish. Your wood is now well-protected and looks great.
