How to Sand Wooden Outdoor Swings for Refinishing (80–220 Grit)

Outdoor swings bring comfort and charm to porches and gardens, but constant exposure to sun, rain, and daily use leads to fading, splinters, and worn finishes. Sanding is the first step to restoring swings before staining, sealing, or painting.

Why Sand Outdoor Swings?

Sanding removes rough spots, old finishes, and weathered wood. It prevents splinters, ensures coatings adhere properly, and enhances the look and feel of the swing.

Tools You’ll Need

• Orbital sander for flat seating surfaces
• Sanding sponges for arms, slats, and curved details
• Wet/dry sandpaper sheets (80–220 grit)
• Vacuum or outdoor blower
• Mask, goggles, gloves

Recommended Grit Sequence

• 80 grit: Removing old coatings and rough fibers.
• 120 grit: General smoothing after coarse sanding.
• 180 grit: Preparing wood for stain or paint.
• 220 grit: Final sanding for smooth, comfortable finishes.

Step-by-Step Process

1. Inspect the swing. Check for loose joints, chains, or cracked boards before sanding.
2. Start with 80 grit. Use 80 grit (25-pack) to strip old finishes and remove splinters.
3. Refine with 120 grit. Smooth seat slats and backrests with 120 grit (50-pack).
4. Prep with 180 grit. Sand arms and flat panels using 180 grit (50-pack) before applying finish.
5. Finish with 220 grit. Lightly sand curved details with 220 grit (100-pack) for a polished result.
6. Clean thoroughly. Vacuum or blow off sanding dust, then wipe with tack cloths.
7. Apply finish. Use exterior-grade stain, paint, or clear sealer for long-term protection.

Special Cases

For hardwood swings like teak, stop at 220 grit for smoothness without reducing stain absorption. For painted swings, scuff sanding may be enough before repainting.

Pro Tips

• Sand with the grain for best results.
• Use sanding sponges on arms and curved edges.
• Seal all joints and cut ends to prevent water damage.
• Apply multiple thin coats of finish for durability.

Aftercare

• Reapply protective coatings every 1–2 years outdoors.
• Cover swings when not in use to extend lifespan.
• Clean with mild soap and water to prevent buildup.

FAQs

• Do I need to sand to bare wood? Yes, for staining. For repainting, light sanding may be enough.
• Can I sand swings by hand? Yes—hand sanding is useful for slats and small details.
• What grit is best before sealing? 180–220 grit provides smoothness and good absorption.
