Marble and granite finishes should be made of natural marble and granite. The surface of the board is required to be bright and bright, with bright color, no knife marks and swirls. A bonding layer should be used under the marble and granite layers, and the bonding layer can be used with 1:4 to 1:6 cement sand or 1:2 cement mortar. The thickness of the cement sand bonding layer is 20 to 30 mm; the thickness of the cement mortar bonding layer is 10 to 15 mm. Before laying the board, it should be coded according to the design requirements, according to the color, pattern, pattern and texture of the stone; when the board has cracks, corners, warpage and surface defects, it should be removed. use. When paving the board, the vertical and horizontal alignment lines should be placed on the base level (mat level or floor surface), and the position of the guide line is generally taken at the width of a sheet from the side of the wall. Marble and granite plates should be wetted with water first, and should be laid after being wiped or surface dried. The laying of marble and granite slabs should start from the alignment line, that is, the line of the slabs is aligned with the alignment. When laying the board, spread the joint layer on the base layer. When cement sand is used to bond the layer, it should be dry and evenly sprinkled. When cement mortar is used to bond the layer, it should be dry hard cement mortar. In order to enhance the bonding between the bonding layer and the board, it is preferable to use a cement slurry or a dry-laid cement watering on the bonding layer, and then the plate is aligned on the bonding layer. The first line is laid on the alignment line, and the subsequent lines are laid according to the previous behavior. The paved slabs shall be flat, the lines shall be straight and inlaid correctly; the slabs, sheets and joints, as well as the corners, edging and walls shall be tightly fitted and shall not have voids. The surface of the marble and granite surface shall be clean, flat and solid; the width of the joint of the plate shall not exceed 1 mm when the design is not specified. After the marble and granite finishes are completed, they should be protected. After the cement mortar strength of the combined layer reaches the requirements, it can be waxed to achieve smooth and clean. The natural marble surface layer can also be broken, that is, it is made of marble pieces. It is required to use color coordination, uniform thickness and no sharp corners of marble pieces. The cement layer is applied to the bonding layer, and the gap between the pieces should be filled with cement mortar or cement and stone mixture. The surface of the broken marble surface layer should be clean, flat and solid; the color of the pieces should be coordinated; the gap between the pieces should be filled and the gap should not be too large. The allowable deviation of the height difference between two adjacent plates of marble and granite is 0.5mm; the row and row of the plates in the surface layer (seam) is within 5m, the allowable deviation of straightness is 2mm; the surface smoothness of the surface layer The allowable deviation when inspected with a 2m ruler is 1mm. The surface roughness of the broken marble surface layer is allowed to be 3 mm.
Paint Roller brush is intended for wall or ceiling painting and such like large and flat surfaces, compared to flat paint brushes. It consists of two basic parts, with the replaceable paint roller covers and the reusable paint roller frames. The sizes usually range from mini 4inch to 9inch. The 9 inch is the most popluar. The paint roller covers pick up the paint, along with the Paint Roller Frame rolling backward and forward, the painting work starts.
