Plant thick and prickly shrubs surrounding the perimeter of the walls to make them less accessible. Good choices include rose and hawthorn bushes.
Paint the wall with anti-climbing paint. Check with your local council to determine the legal restrictions of using anti-climbing paint. Anti-climbing paint leaves an oily and slippery surface on the wall that is extremely difficult to climb.
Add barbed wire or anti-climbing spikes to the upper ledge of the wall to discourage climbers. Anti-climbing spikes are attached to the top of a wall using cement.
Things You Will Need
- Barbed wire
- Anti-climbing paint
- Anti-climbing spikes
- Always place a sign on the wall warning potential climbers of the danger of climbing on the wall. A "No Climbing" sign may deter climbers, but be sure to place a sign warning of anti-climb paint, barbed wire or anti-climb spikes to protect both yourself legally and potential climbers from harm.
