Rubber Designs Mastic Adhesive Glue is a polyurethane based joint sealant. It cures under the influence of atmospheric moisture to form an elastomeric material with adhesive properties, in some cases, without the need for priming of the substrate. The adhesive glue formula features strong, early wet strength, to resist slippage on vertical surfaces and is water resistant once fully cured.
