Why Pool Decks Get Slippery — and How to Fix It
Why pool decks get slippery comes down almost entirely to one culprit: a thin algae film that grows on constantly damp concrete or pavers and turns a normally grippy surface into something closer to wet glass.

Why Pool Decks Get Slippery: The Algae Film Behind It
Pool surrounds stay wet longer than any other exterior surface on a property, thanks to splash-out, humidity, and shade from surrounding landscaping. That constant moisture is exactly what algae needs to establish itself, and it does so faster on a pool deck than on a driveway that dries out between rains.
Why Pool Decks Get Slippery: Why Slip-Safe Cleaning Matters Most
Pool deck power washing removes that film at the surface without over-polishing the concrete or pavers, which matters because a surface that's too smooth can actually be more dangerous wet than one with its natural texture intact.
For Frontenac homeowners, this is a service worth prioritizing each season — a clean pool deck isn't just about appearance, it's the difference between a safe pool area and a liability waiting to happen.
