A slippery outdoor floor isn't a cosmetic problem: it's a fall risk, especially for children, older people and on steps.
Common causes
- Algae: the number one cause in damp, shaded areas; it forms a slimy film when wet.
- Grease and built-up dirt: on driveways, barbecue areas and outdoor kitchens.
- Polished materials: some tiles and stones are slippery when wet even if clean.
- Glossy sealers: some shiny finishes reduce grip.
How to fix it
If algae or grease is the cause, a technical clean that removes the film usually restores the original grip. If the material is polished, anti-slip treatments increase roughness without replacing the floor.
FAQ
Will cleaning stop it being slippery?
If algae or grease is the cause, yes. If the material is polished, an anti-slip treatment is needed.
