The adhesive strength between a thin spray-on liner and rock is an important property controlling the design and performance of spray-on liner support systems. A review is presented of the various adhesion test methods used by the coatings, microelectronics and concrete industries. The advantages and disadvantages of these test methods with respect to thin spray-on liners are discussed. From this review and past experience measuring adhesion between thin spray-on liners and rock, a suggested test method for thin spray-on liner materials is presented. This method is a slight modification of other methods and is based on direct pull-off of an elevator bolt that is attached to a liner with strong epoxy.
