7cm*9.5cm thick 1.5cm stone can be directly attached to the wall?

Because the stone itself is relatively heavy, although your block is not big, if you stick it in a relatively high position, you will be in danger of falling and hurting people. Generally, the construction method is selected according to the paving height. For a lower height, cement mortar can be used for paving, and for a higher height, dry hanging is selected, which is safer. 1, mortar paste is divided into two types, one is to put a layer of cement mortar on the brick wall, and then scrape 3-5mm plain cement slurry behind the stone; The other is hanging, that is, winding the stone on the incision from top to bottom with copper wire, and fixing the other end on the wall. First, the stone is fixed on the surface with gypsum, and then the gap between the stone and the wall is grouted. 2. Dry hanging can also be divided into several methods: for external walls, steel frames should be made first, and then stone materials should be hung. If it is indoors and the floor is not high, you can use wooden boards as the back wall, and then install the screws, or directly install the screws on the cement wall and then hang the marble drywall. The cost is higher, but compared with sticking stones directly on the wall, the safety factor is higher in the future, and marble is relatively difficult to fall off and relatively easy to replace.

Hope to help you, hope to adopt!
