However, with regular use, precast concrete fences can become weathered, stained and dirty. To ensure that your fence remains looking good for years to come, follow these 7 tips for cleaning and preserving your precast concrete fence:

  1. Precast concrete is porous and will absorb spills quickly. Mop up any liquid spillages as soon as they occur to prevent staining the surface of the material.
  2. Regularly pressure wash your precast concrete fence using mild detergent to remove dirt build-up and grime. Avoid using harsh chemicals which may cause damage over time.
  3. To protect your precast concrete fence from staining and further weathering, seal the surface with a quality concrete sealer.

  5. Keep weeds away from your precast concrete fence by removing them as soon as they appear. This will prevent them from damaging the fencing material over time.
  6. Minor cracking along the edges of precast concrete fences isn’t uncommon due to regular wear and tear. Repair these cracks using quality filler and sandpaper to prevent further damage.
  7. Over time, wear and tear may cause the structure of your precast concrete fence to weaken. Regularly check your fence for any signs of structural damage such as leaning or buckling, so that they can be repaired before they become a safety hazard.
