Restoring Wooden Window Frames with eQualle Sandpaper Sheets (80, 150, 220, 320 Grits)

Wooden window frames often show signs of wear from sunlight, moisture, and seasonal changes. Cracked paint, rough edges, and faded finishes can all be repaired with proper sanding. Using eQualle Sandpaper Sheets (9 x 11 inches), you can prepare your frames for a fresh coat of paint or stain that lasts.

Why Sanding Matters for Window Frames

Sanding removes peeling paint, evens out rough edges, and opens the wood grain for better primer and paint adhesion. Without sanding, new coatings may peel quickly under changing weather conditions.

Essential Tools

• eQualle Sandpaper Sheets (9x11 in)
• Sanding block or detail sander
• Scraper for heavy paint removal
• Tack cloth or vacuum
• Primer and exterior paint or stain
• Painter’s tape and drop cloths

Recommended Grit Sequence

• 80 Grit (25-pack) — For stripping peeling paint and leveling rough wood.
• 150 Grit (50-pack) — For smoothing after coarse sanding and refining edges.
• 220 Grit (25-pack) — For fine sanding before primer or stain.
• 320 Grit (50-pack) — For polishing between coats of paint for a flawless surface.

Step-by-Step Process

1. Prep the area. Remove old caulk, tape off surrounding glass, and lay drop cloths.
2. Strip with 80 grit. Sand off peeling paint and rough, weathered wood.
3. Smooth with 150 grit. Refine the surface and prepare for finer sanding.
4. Fine sand with 220 grit. Create a clean, even surface ready for primer or stain.
5. Apply primer. Use an exterior-grade primer for weather resistance.
6. Polish with 320 grit. Lightly sand between coats of paint or varnish for a smooth finish.
7. Apply final coats. Finish with exterior paint or stain for long-lasting durability.

Special Cases

For older historic windows, avoid aggressive sanding that can damage decorative details. Start with 150 grit instead of 80 to preserve the woodwork.

Pro Tips

• Sand with the grain to avoid scratches.
• Use a sanding sponge or folded sheets for corners and grooves.
• Vacuum dust before painting to prevent adhesion issues.
• Apply at least two coats of paint for outdoor protection.

Aftercare

• Inspect frames yearly for cracks or peeling paint.
• Touch up paint as needed to prevent water damage.
• Reapply protective finishes every few years to extend life.

FAQs

• Can I sand without removing all old paint? Yes, but peeling or flaking paint must be removed for durability.
• What grit is best before primer? 220 grit creates the ideal surface for strong primer adhesion.
• Can I sand by hand? Yes, especially for narrow edges and decorative trim.
