Plaster Magic’s Single Adhesive Cartridge is for the project that just needs a little more adhesive, but not a full homeowner’s pack. Plaster Magic® Adhesive must be used in combination with Plaster Magic® Conditioner as instructed (see Instruction Sheet). Failure to follow the directions could render unsatisfactory results. You must make sure that plaster bits and or broken keys are not holding the plaster away from the lath. This may prevent the adhesive from bonding and increase the likelihood of plaster breakage when you clamp it. Made in the USA!
