Slippery Paver Algae on Patios & Walkways — Myrtle Beach Homes
Slippery Paver Algae on Patios & Walkways — Myrtle Beach Homes — what this page covers
Paver algae is a liability, not just an eyesight issue — shaded beach patios stay damp enough that the biofilm never dries out. Cleaning removes the film and the organic matter in the joints; re-sanding and sealing locks the base so regrowth takes 2–3x longer. Problems with driveway paver cleaning and sealing rarely start with the surface itself — prep and materials are usually behind them, and the fixes below are the ones that hold.
