How to clean drywall after sanding

Using water is the best way to clean drywall dust because the dust absorbs the water and becomes too heavy to float through the air. You can then sweep or vacuum the drywall dust without kicking up more dust. Start by wiping down the walls with a damp cloth.

Drywall tends to soak up water and split as it dries. As you vacuum the wall and wipe it down with a microfiber cloth, you may push piles of dust onto the floor, near the baseboard. Be sure to vacuum this dust before you begin to paint; otherwise, it could become airborne and ruin your smoothly painted wall.

Capturing dust

Blowing sanding dust off your wood project with an air compressor or brushing it onto your floor can still result in it ending up in your wet stain or finish. Instead, use a bristle attachment on a vacuum to safely capture it once and for all. Or, remove the dust with a damp cloth.

Use sandpaper or a sanding block to dull any uneven surfaces, wipe away dust with a damp cloth and let dry thoroughly.

This messed up a near-perfect finish by making the joint compound somewhat wavy. The primer protects the wall from over-sanding, and you create a smooth surface ready for the top coats of paint.

Particles at 5µm in diameter (respirable) will settle in about 8 minutes. Particles with a diameter of 1µm (respirable) will take up to 4 or more hours to settle.

Over time, breathing the dust from drywall joint compounds may cause persistent throat and airway irritation, coughing, phlegm production, and breathing difficulties similar to asthma. Smokers or workers with sinus or respiratory conditions may risk even worse health problems.

Short-term exposure to drywall dust irritates the eyes, skin, and respiratory system. Dusty construction sites can create coughing spasms, throat irritation, and breathing difficulties. Long-term exposure increases the risk for more serious health conditions associated with the dust ingredients.

1. Provide misting water sprays sufficient to reduce airborne dusting from demolition work; 2. Apply additional water dust suppression applied during dry weather; and 3. Avoid dust-generating work must be avoided on high wind days.
