According to the drawing requirements, the exterior wall tiles of the project are 230 × 60mm specification, I easy to paste ceramic tile adhesive, which shall be constructed by our company.
2.
After the materials enter the site, the project department shall appoint a special person to receive and store them, timely take samples for retest, paste sample blocks, and conduct pull-out test.
The process flow of face brick inlaying of the North-South facade and West facade of the project: base cleaning → 15 thick 1:3 cement mortar priming and brooming, mixed with 3% waterproof powder → brushing a layer of plain cement slurry → 15 thick waterproof powder and waterproof sand Harvest rough finish of mortar cover → snap and arrange brick control line and detail line on the outer wall surface → paste model row and column bricks at internal and external corners and door and window openings according to the control line → inlay face bricks with 5-thick waterproof powder mortar → pointing with waterproof powder mortar → cleaning → curing.
The spacing of shooting nails shall ensure that the steel mesh does not warp and fall off..
(4) tdj2 theodolite shall be selected to check the geometric dimension and wall perpendicularity of the external wall of the main structure, and a through line shall be snapped at the large corner of the external wall.
The dimensional deviation of facing bricks shall be within the range specified in extruded ceramic bricks (GB / t4100-2015).
Among them, facing bricks, bonding materials and joint filling materials shall have the factory inspection report and product certificate of the manufacturer, and the geometric dimension, surface quality, water absorption, frost resistance and other indicators of facing bricks shall be rechecked.

Project overview.
Preparation basis 1 Standard for quality acceptance of Building Decoration Engineering (gb50210-2018) 2.
The construction party shall complete the procurement and supply of face tiles.
East facade face brick inlay process flow: empty drum wall beating (the first leveling layer and the second base layer), the average thickness of knocking is 75 ~ 78mm → the wall is hydrated, cement and glue powder are sprayed → the wall is roughened → dotting → roughening, the roughening thickness is 75 ~ 78mm → cement mortar is troweled, finished, and the leveling thickness is 75 ~ 78mm.
This scheme is mainly for the construction of exterior wall facing brick.
The reconstruction project 1# building of a certain Guoba factory is located at No.
