Safety First

 

 

• Always wear a dust mask, safety goggles and gloves to protect against wood dust and chemicals.

• Ensure proper ventilation when using chemical strippers or solvents.

• Use protective gear when operating power tools like sanders to avoid injury.

• Follow manufacturer instructions on chemical strippers to avoid hazardous reactions.

 

 

Tools & Materials

 

 

Item

Purpose

Sandpaper & sanding blocks

Smooth and prepare surfaces by removing old finish.

Chemical stripper

Dissolve old varnish or paint for easier removal.

Scrapers/Scarifiers

Remove residual finish and debris from wood surface.

Wood filler

Repair cracks and imperfections before refinishing.

Finishing oil / varnish

Protect and enhance the wood’s appearance with a final coat.

 

 

Step-by-Step

 

 

1. Prepare the work area – clear the space and cover surroundings to catch dust and debris.

2. Clean the wood surface – remove dirt, grease and loose paint with a suitable cleaner.

3. Sand thoroughly – use progressively finer sandpapers to remove old finishes and smooth the surface.

4. Apply a chemical stripper if needed – follow instructions to safely remove stubborn coatings.

5. Repair and fill – use wood filler to fix cracks, holes or imperfections and sand smooth once dry.

6. Stain or oil apply – choose your finish, applying evenly with a brush or cloth for a natural look.

7. Seal and cure – finish with a protective topcoat if required and allow ample time for curing.

 

 

Completion Checks

 

 

• Surface is uniformly smooth with no traces of old finish and free of dust or debris.

• The applied finish is even, cured and enhances the wood grain naturally.

• Final inspection confirms there are no runs, bubbles or missed spots.

• The wood’s enhanced appearance and integrity is maintained post-refinishing.

 

 

When to Call a Pro Instead

 

 

If the wood surfaces are heavily rotted, structurally compromised or form part of a heritage asset requiring expert conservatory skills, it is best to consult a professional conservator or experienced wood restoration specialist.
