Brush and Methods of Use

摘要

A brush for applying a viscous coating to surfaces such as a driveway, has a composition and conformation promoting an even application of the coating. The brush has bristles of a given, number, density/spatial distribution, free length, thickness and elastic modulus that in combination provide a controlled leakage of viscous coating past the brush when the handle thereof is held at a given angle and subjected to a given downforce to facilitate applying the coating.
