Baotou GRC The flat decoration of components of different types, specifications and sizes shall meet the requirements of JC/T940, with the length or width not less than 120mm and the thickness not less than 8mm. GRC Line thickness and structure selection (1) The thickness of thin shell type components is about 8~15mm, which is suitable for product types with smooth shape and simple process, such as line plate, general column (shell), decorative plate, etc. (2) The thickness of medium thick plate components is about 12~25mm, which is suitable for product types with large shape fluctuations and complex process, such as relief, column head, scroll (decorative block), etc. (3) The thickness of special-shaped structural members is about 15mm~30mm, which is suitable for sculpture, large flat plate, large members, etc.
The installation process of GRC component plate decoration: the base wall is firm and firm, without hollowing, peeling, oil and other sundries. Paste the base wall according to the plate line, open the glass fiber mesh at the back of the plate line, 20mm at the top and bottom for adhesion, and evenly apply the polymer mortar on the back of the plane line, with a thickness of 6mm. Scrape off the excess polymer mortar with a trowel brush, and form a strip with a thickness of 5mm, Place the flat line 100mm above the horizontal line and rub it up and down. Until the eaves on the horizontal line overlaps with the horizontal line, repair the top of the horizontal line 24 hours after pasting the horizontal line, 20mm at the bottom of the horizontal line at the grid cloth and the longitudinal joint, evenly apply a layer of polymer mortar with a trowel, 2mm thick, paste a layer of standard mesh cloth, and then apply a layer of polymer mortar, 1mm thick, 1000 standard grid width mm, and overlap each side by 50mm; The length depends on the slab line.
Before the installation of some large GRC line flat lines, metal accessories need to be placed to prevent the flat lines from sliding before the polymer mortar is solidified. The treated flat line can be painted, but the following points should be noted before painting: the flat line has been completely bonded, and the polymer mortar has solidified and hardened, that is, 24 hours after bonding. Flat line joints shall be sanded. Remove dust or dirt from the flat line.
