Grass-roots treatment → hang the reference line, talk about the dividing line → paste the thermal insulation decorative board → fix the anchors → seal the silicone sealant → remove the protective film and check for acceptance.
(1) Determine the exact grid size of each facade, draw the grid lines by hanging horizontal lines against vertical lines, and construct from top to bottom (or bottom to top) row by row along the upper end of the wall.
(2) Paste and fix the horizontal lines and vertical lines on the male corners on both sides of the same facade. Construction along the horizontal direction of the top floor of the building. And reserve the horizontal and vertical separation seams according to the regulations to adjust and correct the finished boards.
(3) When the metal carved board is installed, mark the expansion anchor bolt coordinates in the corresponding grid line on the wall, drill the anchor bolt hole with an electric drill and insert the expansion plug. When using the expansion plug, the depth of the anchor bolt hole is 1 cm larger than that of the plastic expansion plug.
(4) The surface of the polystyrene board to be pasted should be brushed with interface agent in advance. In the single grid line, use a toothed scraper to evenly wipe the adjusted adhesive mortar, the area is ≥ 60%, and the thickness depends on the flatness of the wall or design requirements.
(5) Align the horizontal and vertical grid lines on the wall, stick the board on the wall with adhesive mortar, and use a 2-meter ruler to compact the board up, down, left, and right. The horizontal and vertical errors should be controlled within ≤ 4 mm, and then Secure the anchors. When fixing the anchor piece, the expansion bolt drives the anchor piece to bear the force. The anchor piece should not be higher than the groove of the plate, so that the plate itself can be flat and on the same plane as the surrounding installed plate surface. Unrestricted tightening is not allowed, otherwise Will destroy the finished board.
(6) The method of straight seam butt joint should be adopted at the male corner of the wall to effectively avoid the cracking of the male corner; ).
(7) When there is an error that needs to be adjusted, it should be installed and adjusted lightly and moved. It is forbidden to pull the pasted board outward or pat the board surface evenly with hands or rubber hammers up, down, left, and right.
(8) 2~3 days after the decorative board is bonded and cured (temperature above 25°C). Leave a gap of about 1 to 1 mm to the surface of the decorative board, and seal it with a few days of weather-resistant glue.
(9) Uncover the protective film on the edge of the board, use adhesive tape to paste the two sides of the board seam into vertical or parallel equal-width seams according to the design width of the board seam, and use a glue gun to squeeze the weather-resistant adhesive evenly into the groove of the board seam. Avoid contaminating the board and other items.
