How to Remove Old Varnish or Stain Before Painting Cabinets

Painting over old varnish or stain without proper preparation is one of the most common mistakes homeowners make when attempting to refresh their kitchen cabinets. The result? Paint that chips, peels, or simply doesn't adhere properly, leaving you with a disappointing finish that won't last.

At Painters Halifax, we've seen countless DIY cabinet painting projects gone wrong due to inadequate surface preparation. Today, we're sharing our professional techniques for properly removing old varnish and stain to ensure your cabinet painting project delivers beautiful, long-lasting results.

Why Proper Preparation Matters

Varnish and stain create a protective barrier on wood surfaces. While this protection is great for preserving the wood, it also prevents new paint from bonding effectively. Without proper removal or preparation, your new paint will:

• Chip and peel within months
• Show brush marks and uneven coverage
• Fail to provide the smooth, professional finish you're looking for
• Require complete redoing sooner than expected

Tools and Materials You'll Need

Before starting your cabinet preparation project, gather these essential tools:

• Chemical paint stripper (gel-based works best for vertical surfaces)
• Plastic scrapers and putty knives
• Fine-grit sandpaper (120-220 grit)
• Sanding blocks or electric palm sander
• Drop cloths and plastic sheeting
• Rubber gloves and safety glasses
• Ventilation fan or respirator mask
• Clean rags and mineral spirits
• TSP (Trisodium Phosphate) cleaner

Step-by-Step Removal Process

Step 1: Remove Cabinet Doors and Hardware

Start by removing all cabinet doors, drawers, and hardware. Label each door and its corresponding hinge location to make reassembly easier. This step allows you to work on flat surfaces and ensures you can reach all areas effectively.

Step 2: Clean All Surfaces

Thoroughly clean all cabinet surfaces with TSP cleaner to remove grease, grime, and cooking residue. Kitchen cabinets accumulate more dirt than you might realize, and any remaining residue will interfere with both stripping and painting processes.

Step 3: Apply Chemical Stripper

Working in a well-ventilated area, apply a thick, even coat of chemical stripper using a brush. Follow the manufacturer's instructions for application thickness and wait time. Gel-based strippers work particularly well on vertical cabinet frames as they won't drip as much.

Step 4: Remove Softened Finish

Once the stripper has done its work (usually 15-30 minutes), use plastic scrapers to gently remove the softened varnish or stain. Work with the grain of the wood and avoid gouging the surface. You may need to apply stripper multiple times for thick or stubborn finishes.

Step 5: Sand the Surface

After stripping, sand all surfaces with 120-grit sandpaper to remove any remaining finish and smooth the wood. Follow up with 220-grit sandpaper for a smooth base. Pay special attention to detailed areas and moldings where stripper might not have reached effectively.

Step 6: Final Cleaning

Remove all sanding dust with a tack cloth or microfiber rag. Any dust left on the surface will create bumps and imperfections in your final paint job.

Professional Tips for Success

• Work in sections: Don't try to strip all cabinets at once. Work on 2-3 doors at a time for better control and results.
• Temperature matters: Chemical strippers work best at temperatures between 65-75°F. Avoid working in extreme heat or cold.
• Ventilation is crucial: Always work in a well-ventilated area and consider using a respirator mask for safety.
• Test first: Try your chosen stripper on an inconspicuous area first to ensure it works well with your specific finish.
• Don't rush: Allow adequate time for each step. Rushing the preparation process will compromise your final results.

When to Call the Professionals

While removing varnish and stain is certainly a DIY-friendly project, there are situations where professional help makes sense:

• You have a large kitchen with many cabinets
• Your cabinets have intricate details or moldings
• You're dealing with multiple layers of old paint or finish
• You want guaranteed professional results
• You don't have the time or tools for proper preparation
