Things get a little more difficult when it comes to laminate flooring or smooth tiles. Firstly – how smooth is the area, and how windy will it be, will the dust just blow away?
If you are fairly certain you can get away with a “powder” on your surface, and have a surface, like laminate, that you aren’t worried about staining then why not run lines using a simple powdered substance like flour or talcum powder. You could even grate chalk using a nutmeg grater if you have nothing more suitable to hand. When your party is over you can simply sweep the floor and give it a mop and it’s all cleaned up.
*Tip – Avoid using sugar as it gets sticky and attracts more bugs.
