Stripping Paint from an Exterior Wood Door with a Heat Gun
Removing paint from a wood door can be accomplished through several methods, including liquid or paste paint strippers, heat application, or sanding. The most suitable approach depends on factors such as the type and thickness of the existing paint, cost considerations, and personal preference.
In my experience, the heat method is often the most effective choice. It tends to be the cheapest option, is easy and quick to use, produces the cleanest results, and is generally the most thorough in removing paint while causing the least damage to the underlying wood. However, the heat method does carry some risks that require caution.
Applying excessive heat to deteriorated, paint-covered wood can dangerously burn the wood or even start a fire.
Use extreme caution when using this paint removal method to prevent damage or fire hazards.
Removing paint with a heat gun is a straightforward process. First, prepare the area by covering or removing any nearby objects. Ensure the workspace is well-ventilated, as heating paint can release fumes.
Next, choose the appropriate heat gun setting – lower temperatures work best for delicate wood, while higher heat is more effective on tougher, thicker paint.
Slowly and methodically, move the heat gun back and forth a few inches from the painted surface, avoiding direct contact to prevent scorching the wood. As the paint softens and bubbles, gently lift and remove the loosened paint in sections using a paint scraper, being careful not to damage the wood grain. After the majority of the paint has been removed, you can go over the area again at a lower heat setting to eliminate any remaining paint residue.
After removing the paint, use progressively finer sandpaper grits to achieve a smooth finish. Be cautious not to use a grit that is coarser than necessary – starting with 120 grit is often sufficient.

Deciding on the right finish can be the most challenging yet crucial step in any refinishing project. The options are plentiful – oil-based, water-based, alkyd, or linseed oil paints. Over the years, I’ve experimented with them all and find that linseed oil paint works best for my windows and exterior window frames, while oil-based paint and primer are ideal for the doors and exterior trim.
Old wood can be treated with heated purified linseed oil, as it is a highly effective way to restore and protect it. When applied to aged, cracked, or dried-out wood, the oil penetrates deeply, replenishing the natural oils and fibers that have been depleted over time. The linseed oil rehydrate the wood, filling gaps to create a smooth, uniform appearance while also forming a durable, water-resistant barrier, preventing further weathering, warping, or rot. This treatment dramatically extends its lifespan and is eco-friendly and non-toxic, making it a safe and sustainable choice. Find out more about linseed oil products from Sage Restoration here.
