Does the foundation wall need plastering? Is there a requirement in the specification?

The plastering of foundation wall should be determined according to the specific design. The plastering of the wall surface is to protect the wall surface from external erosion, and it needs to be constructed according to the specific design. Plastering must be carried out in accordance with the design requirements. If the design drawings do not require plastering, plastering is generally not required.

Different gypsum-based parts need different gypsum thickness.

Ordinary plastering-18mm; ; The surface is smooth and smooth, and the summer-planting is smooth.

Intermediate plastering-20mm; The surface is smooth and clean, the summer-planting is smooth, and the line angle is straight and clear.

Advanced plastering-25mm. The surface is smooth, clean, uniform in color, without smearing, and the line angle and gray line are straight and square, clear and beautiful.

Quality problems:

1. Weak adhesion, hollowing and cracking: weak adhesion, hollowing and cracking between paint layer and substrate. The main reason is that the base is not clean, washed with water, not wet enough, and the concrete surface is not coated with interfacial agent. Due to the strength growth and hardening process of mortar, uneven shrinkage stress is generated and dry shrinkage cracks are formed. Cement mortar wall cracks, frost, fall off.

2. The plaster layer is too thick: the thickness of the plaster layer greatly exceeds the regulations, especially if it survives once, it will crack the plaster layer. The thickness of plastering layer should be controlled by screed, and it is advisable to keep 20 mm The operation should be layered and intermittent plastering, and the first time should be wiped again after the final set, so as to avoid survival again.

3. Doors and windows frame joints are not filled with ash or ash, which leads to empty drums and cracks on both sides of the window frame. Doors and windows joints should be handled by special personnel as a process. Door and window frame joints must be filled with cement mortar or fine stone concrete after laying foaming agent to prevent cracking and water seepage.

4. The use of different kinds of mortar to paint the wall should be distinguished and not mixed. Mortar should be used when mixing. It is forbidden to mortar overnight, and the floor ash should be cleaned at any time during operation.
