For the concrete surface, the flat wall should be riveted at the mouth of the cave, the mortar is soft and irregular, and the brush surface of the concrete block bracket protrudes again, and then the brush is cut to cut the concrete grid base. 10% caustic soda aqueous solution is used to clean oil-based surfaces, dust, etc. And drying the water-alkali solution. Clean leveling is received until it is attached to all cement mortar concrete blocks behind the surface, and the wall is mixed with a sticky broom (107), pointing to a uniform mortar. From the last setting, it is far from being rejected. It has higher power.
Can the coalescence wall be repaired? When the porous concrete block base is watered in advance or 2 hours before the wall is completely wetted by the batch of ash 1 hour, the bond strength between the mortar and the wall caused by the wall water absorbent (concrete block expansion) mortar decreases, resulting in poor water absorption of the flowing mortar, which is not an easy task, and in addition, it will form a stratification phenomenon. The water seepage depth is 8~ 10mm, sprayed with 100% glue, brushed with cement mortar first, and washed with 1: L: 6 mortar at corners. 2) net hanging construction
Can the wall be repaired? After the foundation layer is processed, it can be hung on the wall. That is, the suspension usually tends to break in a partial range, and the inner layer of another material has such a structure, such as a floor tile, and has a low thermal range. The effect of reducing the Rachel of nail formwork manufacturing depends on the irregular cracking of water wall needed to prevent shrinkage cracks caused by different materials due to different shrinkage effects.
Can the coalesced wall be repaired, because it is used to separate the wall from the floor, and some wall bricks are made of different materials. Changing the crack material to APT will affect the waterproof effect and the quality and appearance of the wall. Cracks should be avoided in construction review and special treatment.
Besides, can the wall be repaired? Special care should be taken between short steel nails and concrete nails, they are too thin or too dense. If it is too thin, the grid will expand easily. The density and thickness of mortar hardly become the gap between the steel walls of mortar layer, and the too dense flatness effect hardly enters the gap between the exterior walls of mortar gap, so as to obtain the required effect of mortar wall effect of adhesive, and it is a waste of manpower and material resources to realize the function of a pile-like template.
In other words, can the coalesced wall be repaired? The gypsum thickness (thin and pure ≮7mm) is basically determined around the upper corner of each wallboard test drop, which is determined when creating a standard ash cake vertical wall from a stacked flat wall perpendicular to the door and window, which determines the top angle of the ash cake. This ash cake needs to be disconnected and marked, and the vertical spacing and the thickness of the vertical wall forming line 1.5M are drawn along the conductor size of 5 cm square, and then set along it. Can the coalescence wall be repaired? The control coil, which can determine the height and width of the horizontal reference line in the vertical identification step of the horizontal bottom plane and control the number of digits of the reference line from the mortar vertical line to the surrounding age, can be used to compensate the thickness of the batten 10 cm and then immediately remove the red dry mortar structure to be plastered, because good wiring and other windowsills are all looking for slopes and drip line, and the vertical and horizontal directions are smooth.
