Cause wall cracking have? How to repair? - Ceramic tile adhesive | | | waterproof coating straight with mortar jointing agent

wall cracking affect beautiful, serious there is quite a safe hidden trouble, should how to solve? The causes of wall crack has a lot of, before to solve the problem, we first need to determine the causes of wall crack, 'suit the remedy to the case' to the maximum extent to ensure the 'problem'. Decorate wall cracking, whether in or after decorating is very easy to happen. Cracking is lighter, will affect the general appearance of household, if cracking in severe cases, will also affect the resident's life, you must be aware of the owners. Found the metope after cracking, we should be how to solve? After wall cracking, we first need to determine what is the cause of wall cracking, know the types of wall cracking, and makes the corresponding processing according to different situations, respectively. One, paint coating cracking metope paint layer cracking, lead to metope appears obvious crack. The cause of this may be the quality of paint is unqualified, in metope paint construction or operation is not standard, it is possible that the construction of the environment temperature is lower, the paint not well film-forming, resulting in metope paint layer cracking. Solution: want to repair the paint layer cracking problem, we need to use the fine sand paper burnish of crack place clean, until no trace of crack, then use the same color paint besmear again can. Second, putty layer cracking in order to make metope more smooth and exquisite, painting effect is better, we need a batch of blow be bored with child operation to metope. If there is crack, putty layer that would lead to crack of wall surface. The cause of this may be the quality of the putty is not up to standard, may also be a group of scraping putty is too thick, it is also possible that operation is not standard, the batch blow be bored with child again, after before the be bored with child again not completely dry. Solution: if because of putty scraping is too thick, we can use sand paper burnish, cracks will batch again blow a thin layer of putty. If it is some other reasons result in the crack of the putty layer, we need to remove the original putty layer, clean up after the grassroots, plaster leveling, batch of blow be bored with child again, when necessary, we also can be in in cracking with grid cloth and kraft paper, and then to leveling construction. Three, wall plaster cracking plaster layer cracking, can also lead to wall cracks. Plaster layer cracking may be due to the use of unqualified material or operation is not standard, this belongs to the abnormal cracking, it is possible that the cracks are caused by the shrinkage of cement mortar, it belongs to the normal craze. Solution: plaster layer in normal cracks. If cracking area is not large, also did not appear fall off phenomenon, empty drum, section in order to save the budget, we can be in in cracking with dacron cloth to repair, after good, normal leveling construction. If cracking area is larger, so we need to knock off the original floated coat, to the plaster layer construction four again, wall structure layer cracking if itself apart, so will lead to crack of metope. The cause of this may be because of the original crack in the wall itself, but did not make corresponding processing during the construction, it is possible that the temperature change of the late, the settlement of foundation and so on, result in the crack of the wall. Solution: if this is the wall cracking caused by temperature change, we can take as cracks in the grid cloth, non-woven fabric or with cement mortar to fill the way to remedy. A new house of foundation generally in three to five years will gradually stabilized, if it is wall cracking caused by foundation settlement, we need to wait until the foundation stability to be repaired. Repair, use cement mortar or elastic putty to fill, and then paste the caulking bring again to prevent cracking. If is the issue of building structure, we need to ask professional for analysis and repair. Five seams, cracks between new build by laying bricks or stones wall and the original wall, didn't prepare the corresponding connection measures, it seams wall cracking is very easy to happen. Precast floorslabs are mainly because the plasterboard or appear a certain degree of shrinkage and location changes, and the old and new wall materials used are not exactly the same, the wall of humidity are quite different. Seams wall cracks are generally for vertical or horizontal seam. Solution: if the crack is small, we can wipe out the putty layer along the metope of cm distance, cleaned up at the grass-roots level, after the cut with a clean bandage cracks in, leveling, afresh again on paint. If metope fracture is bigger, we need to cement and sand according to: the proportion of the configured, fill in the gaps, filled with gypsum, the last bandage or dacron buiter, cracks in the dry, then blow be bored with child, painting processing.
