Two surfaces are "sticky" if breaking their mutual contact requires a finitetensile force. At low fractal dimensions D, there is consensus stickiness doesnot depend on the upper truncation frequency of roughness spectrum (or"magnification"). As debate is still open for the case at high D, we exploitBAM theory of Ciavarella and Persson-Tosatti theory, to derive criteria for allfractal dimensions. For high D, we show that stickiness is more influenced byshort wavelength roughness with respect to the low D case. BAM converges athigh magnifications to a simple criterion which depends only on D, in agreementwith theories that includes Lennard-Jones traction-gap law, whilePersson-Tosatti disagrees because of its simplifying approximations.

Stickiness of randomly rough surfaces with high fractal dimension: is there a fractal limit?
