Exterior wall paint in the construction process may involve the step of the seam. A lot of people stop at this step, because they do not know how to do the operation of the seam, and worry about the whole project being destroyed.
The following powder coating powder manufacturer teach you specific practices and principles.
Wall paint seam practice: 1. Notch: follow the wall insulation layer process to go, roof insulation brushing can gradually laser cutting slot, laser cutting deep to the bottom of the frame column, parts and package door cover along the frame flush, slot total width of 5 cm, slot interval for 4 layers.
2 fill slot hole: in the slot cavity first powder a bond mortar, then embedded in alkali resistant grid spread all the inner cavity, and the left and right 2 directions widened to the wall is not less than 20 cm long, to ensure that the wall surface alkali resistant grid cloth reinforcement lapping.
Then, after filling the slot hole with bonded mortar, we can install the precast member of the sub-grid seam, and fill the seam glue twice, and the deep layer reaches the steel mesh.
The caulk must be filled with density so that water cannot get in.
3. Close the mouth and edge: after the partition seam inserts are installed, the painting of wall surface bonding mortar is carried out. Pay attention to the connection between the upper and lower sections of the partition seam inserts must also be carried out, or the actual effect will not be achieved.
The width of the general dialog box boundary is 10MM, and the width of the separation seam is 20MM. Their material is all gray and black plastic boundary, and the effect is basically the same -- to avoid the wall deformation caused by heat rise and cold contraction. Split and beautiful.
If the wall insulation is mixed with polystyrene particles should not exist, if the adhesion of high-density polystyrene insulation board to not destroy the comprehensive alkali resistant grid cloth, our approach is not to do meters separated, in the late selection of architectural coatings to make engineering drawings specified shape design.
Exterior wall paint seems according to the design of the separation size, with the method of line on the wall to draw a good separation.
When separating, pay attention to the vertical line to make a straight line, horizontal line to maintain the vertical weight.
The separate size basis is not the same as the main material and scheme design is also different.
Imitation stone exterior wall paint partition 80*120cm,90*150cm and other specifications.
It can be horizontal or vertical.
The total width of the slot is consistent with the color paper, and the total width is 9mm.12mm.15mm.
In general, two colors should be saved at the joint and paper tape (minimum width of 9mm), to maintain a clear wire frame. The vertical.
The grid seam tone is mostly gray black, but also milky white. Dark gray, or any other shade of the design.
In the construction process, a special sealant must be used to brush the seam first, and then stick on it and maintain the paper tape.
Note: first, it is not possible to brush the seam after the construction of the construction paint, so that not only the brush is not neat, and it is very easy to pollute the wall; second, you can't use the general paint seam, which is very easy to fade. Peeling. Falling off.
