Be sure to hang Profile Pvc when plastering the interior walls

If the instructions are not omitted in the marking instructions, as long as the columns, shear walls and all the filling wall connections of the concrete structure, Profile Pvc or wire mesh is required, no matter what the filling material is. It is a mesh woven with steel wire or a mesh woven with pvc profiles. Wire mesh is stronger than Profile Pvc and more expensive.

To prevent wall cracking, pvc profiles should be hung when plastering the interior walls. When new houses are generally delivered, they have not been built for a long time, so the settlement of the walls is not very good. At this time, the intersections of light walls, beams, etc. with load-bearing walls will have slight cracks as they settle. For light walls, kraft paper or Dacron cloth can be used for treatment. Strips of perforated kraft paper can be used for corner joints. Grid tape is generally used for the treatment of slightly larger gaps.

Houses that are a little older are generally brick walls or sand-lime walls, which are very prone to cracking. Because the bricks have air flow, no one can avoid it. Using methods such as patching can extend the time for cracking to appear, but it cannot guarantee that there will be no cracking at all.

Now the energy-saving exterior wall insulation plastering of buildings needs to prevent cracking. Because the insulation dry powder mortar has low strength and thickness, it is easy to crack, so it must be covered with pvc profil before the surface layer.

Profile Pvc is a new type of inorganic composite material. It can be embedded in the wall to evenly disperse the stress such as extrusion and impact on the wall, so that the insulation layer has high impact resistance and plays the role of "soft steel bar".
