When laying marble veneers, the base ash and debris should be thoroughly removed, rinsed with water, and dried. The bonding layer must be dry hard mortar. The mortar should be mixed well and no dilute mortar should be used. The mortar was wetted and the base layer was cemented. After the cement slurry was evenly spread, the mortar was bonded and the combined mortar was rubbed. Before the panels are applied, the panels should be soaked and dried. After the trials, the panels must be set up. After positioning, press the plate evenly and compactly. >>>Links: Quality Standards for Acceptance of Ground Works During the inspection, attention should be paid to whether the marble veneer is smooth and firm, the joints straight, no skew, no stains and grouts, the surface clean, and the color coordination. In addition, it should also pay attention to whether the joints have high and low deviations, and whether the plates have empty drums. Natural granite is igneous rock, also known as acid crystal deep diagenetic rock, which belongs to hard stone. Made of feldspar, quartz and a small amount of mica. Granite structure is dense, showing an overall granular structure. According to its crystal particle size, it can be divided into three types: "Pine", "Crystal" and "Fine Grain". Its color is mainly determined by the color of feldspar and the distribution of a small amount of mica and dark minerals. Usually it is gray, red, enamel or gray, red and white. After polishing, it forms different shades of color. The beautiful speckle pattern, the pattern is characterized by small and uniform grains, and distributed stars like mica highlights and sparkling quartz crystal. The degree of crystallinity of marble is poor, and the surface has few fine grains, but a circle-shaped, twig-shaped or vein-like pattern, so it is possible to distinguish between these two kinds of stone.
