Do Power Brushes Remove Polymeric Sand From Paver Joints?
Yes, power brushes can remove polymeric sand from paver joints — but it depends on several factors: how well the sand cured, how aggressive the bristles are, and how much downward pressure you apply. Fully cured polymeric sand with a soft nylon brush at light pressure is generally safe; stiff wire bristles or under-cured joints are more likely to pull it out.
