When installing floor stone, it's important to check the rubber mesh on the back of the stone. If the rubber mesh is torn off, the stone becomes more vulnerable during construction, and water from the cement slurry may seep through the stone’s grooves, creating a crack-like appearance. If the mesh remains intact, you might hear a hollow sound when tapping the stone two days after installation, which can indicate improper adhesion. For treatment, if the rubber mesh is firmly attached to the stone, it's best not to remove it and proceed with direct installation. However, if the mesh is loose or detached, it's advisable to remove it before proceeding. If cement slurry oozes out from the surface, you can gently scrape it off using a wallpaper knife about two days after installation. Construction Tips: A. For beige and white stones, use black cement for the mortar mix and white cement for the back of the stone. Dark-colored stones should be installed using black cement throughout. B. The cement mixture should be a dry, hard mortar (kneaded into a compact mass), and the back of the stone should be coated with a 5mm thick layer of pure cement paste. Never pour liquid cement slurry directly onto the mortar, as this can weaken the bond and lead to poor results. C. Before laying marble, plan the layout carefully by considering color, grain pattern, and overall arrangement. Start by identifying the main area, then work on smaller sections. Natural stone often has variations in color and texture, so careful planning helps achieve a balanced look. D. When caulking the stone, use black cement for dark materials and white cement mixed with appropriate pigment powder for lighter colors. Avoid using marble glue, as it can stain the surface and affect the final appearance. E. After installation, consider applying a mirror finish or protective coating to prevent damage from oil, acid, or alkaline substances. This will help maintain the stone’s beauty and durability over time.
