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.

Is it time for pressure washing for exposed aggregate?

  • Driveway or walkways look dark, gray or streaky
  • Green or black growth in shaded areas and along edges
  • Slippery surfaces after rain
  • Oil, rust or tire marks you can't scrub out
  • You're getting ready to sell, seal or paint

Where the grime comes from

  • Dirt and pollen that settle into the pores of concrete
  • Mold, mildew and algae in damp, shaded spots
  • Oil and fluid drips from vehicles
  • Rust from sprinklers, furniture and fertilizer
  • Tire marks and general foot traffic

Safe steps for homeowners

  • Sweep off leaves and loose debris so they don't stain
  • Blot fresh oil drips with cat litter or an absorbent right away
  • Point sprinklers away from walls and walkways to cut down on rust and hard-water stains
  • Rinse pollen off with a garden hose during heavy pollen season

Why more pressure isn’t better

  • Etched lines and 'zebra stripes' from holding a narrow tip too close
  • Water forced into window frames, door sills and siding laps
  • Damaged plants and lawns from chemical runoff
  • Injuries: a zero-degree tip can cut skin, and wet surfaces are slippery

What happens on the day

  1. Walk the property and note surfaces, stains and anything fragile
  2. Protect plants, outlets, lights and doors, and move small items
  3. Pre-treat organic growth and degrease oil spots
  4. Clean with the right pressure and a surface cleaner for even results
  5. Rinse, post-treat to slow regrowth, and walk the job with you

Pressure Washing for Exposed Aggregate in North Charleston, SC

Shaded driveways, walkways and pool decks in South Carolina grow black mildew and algae quickly and can become slippery. Pre-treating the growth before washing, and post-treating after, keeps them clean longer than pressure alone.

Spring pollen season in South Carolina coats houses, cars, screens and patios in a yellow-green film, and pollen gives mildew something to feed on. Many homeowners book their wash after pollen season ends so the house stays clean longer.

Red clay soil is common in parts of South Carolina. Rain splashes it onto the bottom of the siding, walls and walkways, and its iron-rich color can stain light surfaces. It usually needs a dedicated clay or rust cleaner rather than pressure alone.
