A wet coat and airborne dust are a bad combination, and cut plasterboard, floor sanding and stone worktop fabrication all throw fine dust that settles into an open film long after the trade that made it has left the room. This is one of the most common reasons a decorator ends up recoating for free.
That's a site management question rather than a decorating one, but we photograph condition on completion and again before returning, so there's evidence if it's disputed.
Not in the same space. We coordinate so sanding on one floor happens while we're painting on another, or we schedule sanding first and painting after.
Yes — dust trapped in a curing film creates a rough, weakly bonded surface that can shed later, not just a cosmetic mark.
The final coat should follow the last dust-heavy operation on that floor, not precede it. We ask which trades are still due into a room before committing to a finish date, because a floor sander booked for the following week will undo an overnight cure.
Temporary zip-wall partitions and negative-pressure screens keep dust contained to the trade generating it. Plastic sheeting alone slows dust rather than stopping it, so on floors with concurrent trades we specify proper containment rather than relying on good behaviour.
A light dusting on a fully cured film can sometimes be wiped and re-examined rather than automatically recoated, saving time and material. Dust settled into a still-tacky film has to be cut back and redone — there is no shortcut that leaves an acceptable finish.
Share the list of trades still due on your floor and we will fit our final coat around them.
The final coat needs to be the last thing that happens in a room, not the thing dust lands on afterwards.
