The problem of extruded board is to fix it when using.

Many construction workers should use a 2-meter ruler to flatten the extruded board during the process of sticking to the wall, so that as much as possible ensure the flatness of the extruded board. At the same time, the parts between the plates need to be extruded, and no gaps can appear, and the mortar cannot be magically polymerized at the joints. If one piece is not finished, it is necessary to extrude the excess polymer mortar inside in time, and at the same time, no gaps can be left between the extruded boards.

If the extruded board itself is not cut straight, then it is necessary to use the strip of the extruded board to carry out the smoothing work. The extruded board should also be pasted horizontally, so that the subsequent sticking will be easier, and the extruded board itself needs to be consistent up and down.

In addition, another problem of extruded board is grinding. The unevenness of the joints of the extruded board itself will lead to unevenness on the subsequent paste. At this time, you can use coarse sandpaper or electric hammer for grinding work. Grinding work needs to be gentle, and the direction of grinding is best to use the circle as the activity. It cannot be polished along the diagonal direction of the extruded board. After polishing, you should use a brush or compressed air to clean up the debris.
