Anti-climb paint

In appearance it is similar to smooth gloss paint when applied but it remains slippery for a minimum of three years, thereby hindering an intruder from gaining a foothold.

As an additional advantage, it leaves its mark on the person touching it and hence makes it possible for intruders to be identified.

Anti-climb paint is often used to deter burglars seeking to enter a building by climbing up to a higher entry point, such as a window on an upper floor.

[1] Anti-climb paint continues to work in hot or cold weather conditions, adhering to the surfaces to which it is applied.

It is particularly effective in preventing climbing on walls, parapets, boundary fences, down pipes, lamp standards and roofs.
