How to Clean Drywall after Sanding (Drywall Dust Cleaning)

Joint compound is used to finish off drywall installation. It covers the joints, screws, uneven levels and offers a smooth finish to the seams. This is then followed by the final step that involves sanding to smooth the compound. This process produces fine white dust that spreads across the entire room.

Therefore, it’s important to clean and remove dust from the drywall before paint application. Otherwise, it might affect paint adhesion. Moreover, removing the dust immediately after sanding minimizes its chances of spreading throughout your house.

But, how do you clean the drywall after sanding? Well, follow the tips below and you’ll find the process extremely simple!

Cleaning Drywall Dust after Sanding

1. Wear a Face Mask

The fine dust released after sanding the drywall is said to contain silica.  When inhaled, silica might cause lung cancer or silicosis. Similarly, dust released from joint compounds, which doesn’t contain silica, might aggravate asthma and cause breathing problems. Therefore, you should avoid breathing any dust produced after sanding drywall. You can achieve this by covering your mouth and nose with a face mask.

2. Cover Your Head, Skin, and Eyes

Use a stocking cap or hat to cover your head while sanding drywall. Moreover, wear a long-sleeved shirt and wear goggles to cover your skin and eyes respectively.

3. Turn off Heaters and Air Conditioners

This will prevent these devices from sucking the fine dust into ductwork. Additionally, remove some airborne drywall dust while working. This can be accomplished by placing a box fan in an open window.

4. Sprinkle the Sweeping Compound on the Floor

The sweeping compound has ingredients that help in ensuring the dust remains on the ground. This prevents the dust from becoming airborne again and makes it simpler to remove. However, ensure you follow the directions from the manufacturer while using the compound.

5. Clean the Floor

After sprinkling the sweeping compound, clean the floor with a shop vacuum. Avoid using the house vacuum, since the fine particles will clog and ruin the vacuum.

6. Wipe down the Drywall with a Damp Cloth

Soak a cloth in water and then squeeze it until it’s almost dry. Use the damp cloth to wipe down the entire drywall to ensure it’s dust-free before painting. The wet cloth might dampen your drywall. Therefore, leave the wall to dry before you apply paint. Moreover, clean the glass windows and doors using a damp cloth. You’ll probably have to vacuum the floor once more after wiping all the surfaces.
