Looks like mortar. Stretches like rubber.
Mor-Flexx® is the flexible acrylic latex caulk for textured surfaces. Its texture mimics the character of many different textured surfaces, including wood, stone, stucco, brick, mortar and composite panels and siding. It won't dry hard and crack like other repair products. It stretches and flexes with temperature changes and movement.
Mor-Flexx looks like mortar, and stretches like rubber! Use Mor-Flexx where a textured, mortar look is desired, indoors or outdoors.
