Mor-Flexx® is the flexible sealant for textured surfaces. Its composition mimics the character of many different textured surfaces, including stone, stucco, brick, mortar, wood 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. Use Mor-Flexx where a textured, mortar look is desired, indoors or outdoors.
