Road crew applies surface tack treatment to prevent tracking while sealant cures.

When sealants are fresh they can feel tacky to traffic until they have fully cured and dust has covered the surface. Tack treatments are designed to reduce tracking and allow traffic onto sealed areas faster

Tack treatments are generally liquid and sprayed with a weed sprayer or similar apparatus. However, it is not uncommon to see sand or bio-degradabale toilet paper used for the same purpose.
