To prevent gypsum board ceiling split in addition to paste kraft paper and cloth what good way?
To prevent gypsum board ceiling split the current treatment only paste kraft paper and cloth.
1, the patch is the use of cloth flexibility, so that the original rigid material can also increase some flexibility, while cloth can also delay the release of stress cracking of the wall to reduce the wall cracking on the wall material force.
2, paste kraft paper is mainly the use of kraft paper itself under the action of transverse stress is not easy to deformation characteristics, when the wall cracking force is less than sticky kraft paper glue or kraft paper itself can withstand the lateral force, these will make the wall The power of surface cracking will not be transmitted to the wall of the putty, in order to achieve anti-cracking effect.
3, posted good, or paste kraft paper is good, there is no corresponding detection standards, there is no conclusion. But the patch and paste kraft paper has a better anti-cracking effect, this is no doubt.
4, patch is to strengthen the flexibility, paste the kraft paper is to increase the rigidity, both posted, then it is hard and soft. If the economy allows, the effect is so better.
5, whether posted or paste kraft paper, the best full, do not stay gaps, then should be "edge" operation, has reached the best results.
Kraft paper and cloth is sure to use, but how to use the method of innovation. At present, in addition to these two, really no other way
1, keel system check is good, large area should be arch. 10 meters long, from arch 1-2cm;
2, more than 10 meters long ceiling should be set expansion joints;
3, gypsum board fixed check again to see if there is no fixed fixed;
4, with gypsum-based powder approved in the gypsum board than with the old powder putty batch on the gypsum board sinking much less impact;
5, with high-quality gypsum board caulking paste to do the joint treatment, the proposed Lafarge, Pratt, Knauf, Long card and other brands.
