Plaster Dust
Plaster dust can pose a risk to wood flooring if not properly managed during and after construction work. While not corrosive in the traditional sense, its abrasive nature and ability to absorb moisture means it must be carefully controlled to prevent damage.
Modern plaster is most often based on gypsum, which is not in itself classified as a hazardous substance. Nevertheless, dust of any type can damage health, and working with plaster can generate quantities of dust that could lead to health problems if not handled correctly.
The plaster stain on hardwood should be cleaned as soon as possible, otherwise, you risk having “burn” marks on the timber.
The guidance provided here is for general information only, as site conditions and flooring types will determine the best approach to protection and cleaning. Contractors, builders, and fitters should take full responsibility for ensuring that appropriate dust control measures are in place.

Plaster dust is a common by product of construction and renovation, created when cutting, sanding, or mixing plaster, drywall, or cement. While not chemically corrosive, it can still damage wood flooring if not properly managed. Its fine, abrasive particles can scratch and dull the surface, especially when walked on or wiped away incorrectly. Plaster dust is also highly absorbent, meaning that when exposed to moisture, it can form a paste that seeps into the wood grain, leading to discolouration or long-term damage.
Unlike ordinary household dust, plaster dust settles deep into gaps and joints, making it difficult to remove. Sweeping can push it further into crevices, while improper cleaning may spread the dust rather than eliminate it. The best way to clean it is to vacuum with a soft brush attachment, followed by a lightly damp microfibre mop to lift the remaining residue without overexposing the wood to moisture. Harsh chemicals should be avoided, as they can react with the dust and affect the floor’s finish.
To prevent damage, it’s best to:
- Cover floors with dust sheets before work begins.
- Seal off work areas to limit dust spread.
- Use dust-extraction tools to reduce airborne particles.
After construction, proper cleaning ensures no dust remains trapped in the floor’s surface. Vacuuming first, then carefully damp mopping, will help maintain the wood’s natural beauty and durability. Taking these precautions will protect the flooring, preventing unnecessary wear and damage over time.
