1. The first product of this overall system is a special adhesive mortar: the 5021 Proliterrasse, available in beige and gray. Its special consistency allows it to not crash under the weight of tiles or slabs. Its water repellency provides excellent resistance to seepage, annihilating the devastating freeze / thaw cycle.

3. This product, when thoroughly kneaded, has a longer open time than ordinary mortars. It thus prevents filming (forming a film on the surface of the product by evaporation of solvents or here, water) too fast from its surface, always detrimental to a good grip. It thus allows a double gluing of the tiles, which constitutes one of the strong points of the system.
