How to Remove Paint from a Door: Chemical Stripper, Heat Gun & Sanding Guide
To remove paint from a door, choose from three methods: chemical stripper (best for multiple layers and carved detail), heat gun (fastest for flat panels), or sanding (for light coatings). For wood doors with multiple old paint layers, apply a gel chemical stripper, let it dwell for the manufacturer’s specified time, then scrape with a putty knife and sand smooth. Always test for lead paint on pre-1978 doors before sanding or scraping. This guide covers all three methods with step-by-step instructions.
Quick Answer
What is the easiest way to remove paint from a door? Apply a gel paint stripper to the door surface, let it sit for the time specified on the label (usually 15–30 minutes), then scrape off the loosened paint with a plastic or metal putty knife. Finish with light sanding. For carved details or mouldings, use a stripper and a stiff brush. For a fast flat-panel result, use a heat gun and metal scraper.

Preparation
Start by gathering all needed supplies. You will need paint remover, scraper, sandpaper, gloves, and safety glasses. Also, get some drop cloths to protect the floor. Having everything ready will make the job easier.
Cover the floor with drop cloths or old sheets. This will catch any falling paint or remover. Tape plastic sheets over nearby walls and furniture. This keeps them safe from spills or splashes. Wear old clothes to protect your skin.
