Where’s the job?

Overview

• Removing existing finishes from doors and preparing surfaces for refinishing is a process designed to strip old layers, damage and build a sound base for a new finish.

• Skill level: 3 / 5 (involves some technical know-how and care with chemicals, tools and surface preparation).

• Typical duration: 2 – 6 hours depending on the number of doors and finish conditions.

Safety First

• Always work in a well-ventilated area, particularly when using chemical strippers or paint removers.

• Wear protective goggles, gloves and a respirator to guard against harmful fumes and dust.

• Follow all manufacturer guidelines and safety warnings on chemical products.

• Cover surrounding surfaces to avoid accidental spills or splashes.

Tools & Materials

Step-by-Step

1. Remove door hardware (handles, locks, etc.) and lay the door on a secure working surface.

2. Protect areas around the door using drop cloths or masking tape.

3. Apply a chemical stripper (or use a heat gun if appropriate) to soften the old finish.

4. Gently scrape off the old finish with scrapers or putty knives, taking care not to damage the door surface.

5. Sand the door to remove any residual finish and smooth the surface in preparation for a new coating.

6. Clean off dust and residue with a tack cloth or damp rag, ensuring the surface is dust-free before refinishing.

7. Refit door hardware only after the new finish is fully cured.

Completion Checks

• The door surface should be free of all previous finish with a smooth, even texture.

• No traces of dust, chemical residue or peeling material remain.

• The door is ready for a primer or new finish application.

When to Call a Pro Instead

If the door has intricate detailing, features hazardous materials such as lead paint, or if chemical stripping seems too risky, it may be best to consult a professional refinisher or a specialised restoration expert.
