Installation and maintenance of natural cultural stone
The shades of the same variety can be combined, and different varieties and specifications can also be combined. The standard is natural, harmonious and pleasing to the eye. The thickness, pattern and color of natural cultural stone should not be overly selected. The color should be rich and varied, and the texture should be crisscrossed, so that the effect will be distinct, the three-dimensional effect is strong, and it is closer to nature. Before construction, the surface of natural cultural stone should be cleaned of dust and debris and dried (when using glue for construction). The cement construction does not need to be cleaned, and it is uniformly cleaned when the construction is completed. If you need a complex shape, it is better to try it on a flat ground. Do not stick cement or glue on the surface of the cultured stone during construction. If it does, please remove it with a damp cloth immediately. Cement is suitable for pasting on general cement walls (paint and latex paint should be shoveled off and leveled). construction glue is suitable for sticking wood board, steel, paint, terrazzo, granite, ceramic tile and other smooth (low water absorption) surfaces, the pasted surface is dry, no oil, no dust. Adhesive stickers for cement walls are quicker, cleaner and more effective, but they are more costly than cement construction. The glue should be stirred evenly when it is used, and it should be opened for half a day in advance when the temperature is low. 5-15mm expansion joints should be left on the ground and outdoor walls. Smaller indoor walls may not be left. The jointing materials include glass glue, cement, caulking agent, rubber strips, or wood thread brushing the required paint joints. . In order to prevent large-scale cultural stones from sliding down during wall construction, marble glue can be used as an auxiliary. After is pasted, rust, powder rust, stone mud, lotus, bluestone, etc. can be painted with a layer of varnish, sandstone and artificial stone are not painted. When painting, first try to paint a small piece of side material to see if the effect is satisfactory. If not, keep the original natural appearance of the cultural stone. Sandstone and all cultural stones are natural when they are not painted (professional stone curing agents are better than varnishes).
