A resilient plant, moss will grow anywhere with moisture, shade and something to grab. Shaded cement driveways in climates with high humidity provide prime habitat for moss to take root. Scrubbing the driveway with a broom and concrete cleanser while pressure washing the surface will remove the moss. The same process can also be used to clean the cement before applying stain or sealant.

  1. 1

    Pressure wash the area to remove large concentrations of moss. Scrub the area with a hard-bristled push broom as you pressure wash.

  2. 2

    Pour a concrete cleanser directly onto the impacted areas. Allow the cleanser to sit for approximately 5 to 10 minutes.

  3. 3

    Scrub the cleanser into the surface of the cement, working in small, concentric circles.

  4. 4

    Rinse the concrete thoroughly with the pressure washer while continuing to scrub the area. Repeat the process as necessary to remove the moss.

Tips and warnings

  • Stubborn moss may require sanding to remove the roots. You can sand a cement pad with a floor buffer and specialised sandpaper. Both are available at most hardware stores for rent or purchase.
