A reliable solution for strong adhesions of marble and granite boards to floors, when a thick layer of mortar is needed. LM 400 Plus is especially suitable for white or light colored marbles, which are sensitive to stains coming from the substrate. It can be also used for other natural stones such as granite, sandstone, limestone, travertine, etc, or artificial stone tiles and boards. Add MARMOLINE MP 20 resin for further adhesion strength and more flexibility.
