When we handle pressure washing for exposed aggregate in Iowa, it comes down to three things: protecting your plants and property, cleaning with the right method, and walking the job with you at the end. On exposed aggregate, the method we use is moderate-pressure wash.
Method and pressure
Cleaning solution: A concrete pre-treatment and degreaser as needed.
Caring for 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.
