How to Sand a Door with an Electric Sander?

To effectively sand a door using an electric sander, follow these steps:

Preparation

Before you begin, make sure you have the necessary tools and materials:

• Electric sander (preferably an eccentric sander)
• GRANAT P400 sandpaper
• Manual abrasive (for rebates)
• Dust removal tools (brush, vacuum)

Sanding the Door

1. Attach the Sandpaper: Securely affix the GRANAT P400 sandpaper to the sanding pad of your eccentric sander.
2. Sanding:
   • Sand the doors evenly without applying pressure.
   • Move the sander in smooth, overlapping passes across the door's surface. Avoid staying in one spot to prevent uneven sanding.
   • Keep the sander flat and level against the door's surface.
3. Sanding Rebates:
   • Use the manual abrasive to carefully sand the rebate areas of the door.
   • Do not use the electric sander in the rebate areas.
   • Use gentle and even pressure.

Finishing Up

1. Dust Removal: Thoroughly remove all sanding dust from the door's surface using a brush, vacuum, or a tack cloth.
2. Inspection: Examine the door to ensure you have achieved the desired level of smoothness and there are no visible scratches or inconsistencies.
3. Coating: Now that the sanding is complete and the dust is removed, you can proceed with the final coating process (painting, staining etc).

Key Points to Remember

• Always use the correct grit of sandpaper for your specific needs. For doors, a GRANAT P400 grit is generally appropriate for a fine finish, as mentioned in the reference.
• Do not press too hard on the sander. The weight of the sander itself is usually sufficient.
• Sand with the grain of the wood when possible to achieve a smoother finish.
• Take your time. Rushing the sanding process can lead to uneven results.
