如何在墙面上涂抹水泥膏药?

水泥抹灰通常用作壁的外部和内表面的理想涂层。水泥膏药通常以单涂层或双涂层施用。施加双涂层膏药,其中厚度需要超过15毫米或者需要获得非常精细的表面。在墙面上涂抹双层水泥膏药的过程包括以下5步。

  • 步骤1-用于抹灰的表面的制备
  • Step-2-Ground work for plaster
  • 步骤3效用第一涂层(或涂层或渲染涂层)
  • 步骤4 - 涂抹第二涂层(或整理涂层或细涂层)

水泥抹灰的步骤指南

Step-1 (Preparation of Surface for Plastering)

  1. Keep all the mortar joints of wall rough, so as to give a good bonding to hold plaster.
  2. 用钢丝刷清洁墙壁的所有关节和表面,在墙面上留下没有油或润滑脂等。
  3. If the surface is smooth or the wall to be plastered is old one, then rake out the mortar joint to a depth of at least 12 mm to give a better bonding to the plaster.
  4. If the projection on the wall surface is more than 12 mm, then knock it off, so as to obtain a uniform surface of wall. This will reduce the consumption of plaster.
  5. 如果表面上存在任何腔或孔,则用适当的材料预先填充它。
  6. Roughen the entire wall to be plastered.
  7. Wash the mortar joints and entire wall to be plastered, and keep it wet for at least 6 hours before applying cement plaster.

步骤2(石膏的地面工作)

  1. 为了在整个墙面上涂抹均匀厚度,首先固定小点在墙壁上。点表示尺寸为15mm×15mm的石膏贴片,并且具有约10mm的厚度。新利18体育官网登录
  2. Dots are fixed on the wall first horizontally and then vertically at a distance of about 2 meters covering the entire wall surface.
  3. 通过Plumb-Bob检查点的垂直度,一个左转。
  4. 在固定点后,垂直条纹石膏条,称为熨平板,在点之间形成。这些熨平板用作用于保持均匀涂抹的厚度的仪表。

步骤3(涂层涂层或涂层外套涂层)

  1. 在砖砌体的情况下,第一涂层石膏的厚度通常为12 mm,在混凝土砌体的情况下,该厚度从9〜15 mm变化。
  2. 第一外套石膏的水泥和砂的比例从1:3至1:6变化。
  3. 在壁面上的熨平板形成的空间之间涂抹第一涂层。这是通过抹子完成的。
  4. Level the surface by means of flat wooden floats and wooden straight edges.
  5. 在平整后,将第一件涂层留下来,但不要干燥,然后用刮擦工具粗糙,以形成第二层石膏的钥匙。

Step-4 (Applying Second Coat or Finishing Coat or Fine Coat)

  1. 第二涂层或精加工涂层的厚度可以在2至3mm之间变化。
  2. The ratio of cement and sand for second coat plaster varies from 1:4 to 1:6.
  3. Before applying the second coat, damp the first coat evenly.
  4. 用木制漂浮物涂上精加工外套到真正的甚至表面,并使用钢刀片,使其成为精加工触感。
  5. As far as possible, the finishing coat should be applied starting from top towards bottom and completed in one operation to eliminate joining marks.

完成抹灰工作后,通过洒水至少7天保持湿,以便产生强度和硬度。
