What to know about cleaning exposed aggregate
Exposed aggregate concrete has stones showing at the surface. Too much pressure can loosen stones at the edges, and the surface looks best when cleaned and resealed.
Avoid: High pressure at edges and cracks, which can pop out aggregate.
How often: Clean yearly; reseal every 2-3 years.
