How to Sand the First Coat of Drywall

Sanding drywall compound is a basic necessity that all renters and home owners will probably need to to do at one point in their lives. It's a good do-it-yourself project since it doesn't need a lot of specialized skill, just patience and time.

Difficulty: Moderately Easy

Instructions

Things You'll Need:

• Hand sander
• Extension pole
• Fine-grit sand paper
• Sanding sponge
• Dust mask

1. Place lights around the room so that you are working in a well-lit area. Shadows can lead to compound ridges and popped nails left un-sanded and un-smoothed.

2. Touch the mud for dryness; there should be no moistness or stickiness. The best sanding results will be achieved if you give your compound 24 hours to dry before starting to sand.

3. Cut the sand paper or sanding screen to the size of the hand sander you have chosen. The hand sander will help distribute your hand pressure evenly. Small jobs are easily done by hand.

4. Start sanding the ridges and lines of compound, using soft but firm strokes. Do not over-sand the area or you will have to apply more compound joint mix to the area. Feel the area for smoothness, and if necessary shine light on the area to look for ridges and uneven spots.

5. Use a dry painting brush or a damp sponge to clean off the excess sanding dust before moving on to the next step. You're ready to apply another layer of compound or paint.

Tips & Warnings

• Remember that you are sanding to smooth out lines and ridges, not to fill the groves that were left in the compound.
