Trowel, joints, bubbles in the plastering project


  When plastering is applied, there will be wall joints, obvious smears, uneven color, and bubbles. Usually, because the raw materials of the mortar are different, the wall is not divided or the grid is too large, and the uneven watering or the calendering before the plastering will cause smears and bubbles. At the same time, if the lime paste is not mature enough, the over-fired ash will not be filtered, which will cause pitting and smearing on the surface of the wall.


Measures to prevent the appearance of smears, joints and bubbles


  1) The wall surface of the outdoor trowel should be chiseled. When using a wooden spatula, the surface should be smeared in a circle shape, then pulled up and down, and the direction should be consistent, light and heavy, and should be connected during construction. The position of the  is selected as a division or a yin and yang angle and a water drop pipe.


  2) When using lime paste, the aging time should be no less than 30d, and filtered with a sieve of less than 3 × 3mm. If finely ground lime powder is used, it should be converted to lime paste 1-2d in advance.


  3) The figure-shaped cement mortar should be fixed on both sides of the division bar. If the surface is covered with ash on the day, the side should be wiped off at the horizontal line. After calendering, the division bar can be used, and both sides should be wiped. 45°; if the surface is not covered with ash, the surface cement mortar must be a certain strength before it can be used as a grid, and should be smeared at 60°.
