As more brushed and textured pre-finished engineered wood flooring products are used, there is a common complaint that comes up post install – “There is a white construction dust on the floor, how do I remove it?”

This dust is mostly from GIB Board/drywall and other airborne construction dust. On darker coloured planks this issue can be a lot more obvious. The most important question is, how can this be prevented in the first place?

Suggestions to prevent white construction dust:

  1. Work with the project manager and stake holders to have the wood flooring installed as one of the last trades on the project – this helps minimise the potential of damage to the floor due to care of it on-site during the project.
  2. Any cutting machines used when installing the floors must have dust collection bags on them.
  3. Shortly after the engineered wood flooring has been installed, use a brush head on a vacuum cleaner and thoroughly vacuum the floors, to remove any loose dust, dirt, and debris that has ended up on the floor’s surface.
  4. Ensure the vacuum used contains the dust and doesn’t release it through its filters again.
  5. Cover the floor as soon as it is able to be walked on, according to the VidaSpace installation guidelines. Do not cover with plastic or polyethylene sheeting.
  6. Do not tape protective covering to the floor, but do secure the edges of the covering where pieces come together so dust cannot migrate under the covering. A common issue is when installers lay protection over a floor but a stone or piece of construction debris gets between the protective covering and the face of the flooring. This can cause extensive damage during the rest of the construction project and doesn’t show up until the protective covering is removed at the end of the project. If adhesion tape bonds directly to the surface of the timber this can also cause issues with the finish of the product so avoid this at all costs

If this issue has arisen on site, here are some suggestions on how to rectify it:

  1. Remove as much of the dust and debris with a brush foot on a vacuum.
  2. The white construction dust is normally calcium-based so you can use a mild acid like acetic acid in dilution with water to remove this. The simplest way to achieve this is to use white vinegar in water mixed in a bottle and spray or squirt onto the floor and use a flat mop to spread over the surface and remove the contamination. Use 50-100ml of vinegar per 1L of water. Use two buckets – one with the detergent and another with clean water to remove the contamination.
  3. Once the floor is dry, wash again with a floor cleaner like marldon cleancare or osmo wash & care – the best outcome will be achieve with a red pad on a buffing machine.
  4. If the problem still persists, which is more likely if the flooring is a very dark tone; if it is a hardwax oil finish a tinted oil such as Osmo, as close to the existing finish colour and sheen as possible could be buffed into the surface. It is critical that professional advice is taken on this and it is undertaken by experienced professionals.
