Flooring: What makes floors slippery?
Generally floors are only slippery when they have some form of contamination on them.
How can you tell if your floor is likely to be slippery?
Very smooth floors, that look shiny, will be slippery when contaminated.
Very rough floors, that feel sandpaper rough, are unlikely to be slippery when contaminated.
For all other floors, you can’t tell by look or touch, you have to test them.
