Why does the ceiling crack again after being painted?

132697321 right. The moisture content of wood is different from that of space, and shrinkage will lead to cracking. In fact, it is not that the wood skeleton ceiling will crack, my opinion is that as long as the moisture content of the wood is appropriate, fixed firmly, the surface layer of gypsum board is reserved for suitable joints, and the gaps are mixed with plaster to add flat, and then paste a good quality connecting belt, usually pay attention to the opening and closing of doors and windows at home, maintain air temperature and humidity in a certain range, do not let the temperature and humidity change suddenly.

It is possible to prevent the ceiling from continuing to crack.

You should still find a painter who paints it.

There's a warranty period for everything you buy.

If you're buying your own materials and they're of poor quality, there's no way around it.

If it's more serious, it's not just the paint problem, it may be the wall problem, I don't know if your house is a new house that has just been built?

The reason for the cracking is that the quality of the connecting belt in the bottom layer is not up to standard or the connecting belt is not used. The painter said that it will still swell and crack after repair, and if you sign a contract, the renovation company should be responsible. The remedy is to cut the crack into small grooves, include putty and sand to flatten, and then brush latex paint to solve the problem, and there will be no more cracks
