The method comprises the steps of brushing colored primer on a base layer by using a roller, after the primer is dried, coating a first layer of texture paint, uniformly feeding, enabling edges to be flat (wet film is 2mm thick), scraping off redundant materials (scraping plate is about 65 degrees), enabling the finishing strength to float mainly (scraping plate is about 10 degrees), and after a layer of paint is dried, coating the paint in a batch by the same method.
8. Pointing treatment
After the split brick binder reaches a certain strength, a split brick pasting and drawing test is carried out, and after the test is qualified, the joint filling construction can be carried out. The caulking agent is adopted for caulking, the caulking material cannot be whitened, turned alkali, cracked and the like, the entering caulking agent is tested, and the caulking material can be used after the quality detection is qualified.
Pouring the caulking agent into a clean stirring barrel according to the requirements of the instruction provided by a caulking agent manufacturer, and adding water according to the requirements to stir uniformly for caulking. The mixed joint compound slurry is not suitable for use after more than 3 hours, and the service time is not more than 2 hours when the ambient temperature is higher than 30 ℃. The slurry which is hard and not used is discarded, and water is not added to be stirred for reuse.
And a seam feeding method is adopted during seam filling so as to reduce pollution of the split brick surface layer. The cone size of the top end of the squeeze bag is selected according to the size of the mortar joint, then the air in the bag is exhausted, and the prepared joint compound is compactly filled into the squeeze bag according to the capacity of 2/3 of the squeeze bag, so that the squeezing pulp is continuous and smooth. When the method is used, moderate force is needed to be applied, one hand supports the pattern extrusion bag to incline 45-60 degrees, the other hand uniformly extrudes and advances forwards, and the extruded joint compound is 2-3 mm higher than the brick surface, so that the joint compound can be used for joint filling of the gap of the large-area split brick.
After the joint filling is finished, the joint pointing is started, and the concave flat joint pointing is adopted, wherein the joint pointing depth is 3 mm-4 mm from the concave of the brick surface. The time interval between pointing and caulking is generally not more than 1h, and pointing materials can be pressed by fingers, so that the judgment is based on non-sticking hands. When the pointing slide is used for pointing, the horizontal transverse seam is firstly hooked and then the vertical seam is hooked, the horizontal brick seam is controlled according to the radian of the constructed wall, and the horizontal brick seam is kept consistent with the radian of the wall. And uniformly applying force, and hooking and pressing for multiple times until the depth is consistent, wherein the joint is compact, and the joint is smooth, straight and smooth.
9. Cleaning and maintaining surface of split brick
Before cleaning, checking whether the mortar joint is cracked or not, and if the mortar joint is cracked, repairing the mortar joint in time. 24 hours after the completion of the caulking (specifically according to the weather at that time), after the bricks are solidified to a certain strength, the brick surfaces are thoroughly brushed with clear water from top to bottom until the bricks are clean (note: grasping the time is very important for the whole construction quality), if part of the bricks are still not cleaned, hydrochloric acid solution with the concentration of 2-3% can be used for cleaning, and the bricks are cleaned with clear water in time.
The construction method is suitable for heat-insulating outer walls with arc sections of houses, villas, schools, parks and the like. The construction method of the invention avoids the situation that the split bricks are directly bonded with the external wall insulation board, avoids the split bricks falling off from the external wall insulation board, and ensures the safety of the building; in addition, the external wall heat-insulating board is positioned between the main body wall body and the air-entrapping block wall body to form interlayer heat insulation, and the air-entrapping block wall body not only forms protection to the external wall heat-insulating board and ensures the service life of the external wall heat-insulating board, but also is used as a pasting matrix of split bricks and ensures firm pasting of the split bricks. The invention adopts a 500mm interval hanging wire method to deeply design the radian of the wall body and control the brick arrangement position of split bricks, thereby controlling the radian of the wall body and achieving the design effect. The brick is selected before the split bricks are paved, the joint mixture is adopted for bagged extrusion joint filling, the corresponding tools are used for pointing, the pollution of the split bricks on the wall surface is avoided, the construction quality and the appearance are effectively controlled, and the environment-friendly effect is good. The exterior wall split bricks are combined with the texture paint extruded sheet lines to form an arc-shaped composite exterior wall system, so that the structure is novel, and the facade effect is attractive. The arc section split bricks are cut bricks with the long side reduced by half, and two color-jumping half bricks with the same color are paved adjacently left and right when paved, so that the density effect with coordinated proportions is created.
