Anonymous users2024-01-24Light steel keel gypsum board ceiling integral ceiling panel joints are treated with caulking putty.
Here's how to deal with it:
1. The cutting lap edge of the base plate should be inverted. Requirements for chamfering: 3mm on the board surface at a 30-degree angle.
There should be a gap of 5-8mm between the base plate and the base plate. The gaps and chamfers are mainly used to fill enough fine slit putty to make the whole ceiling base layer integrate. Avoid cracks caused by gaps left between the base plates when there is a slight shrinkage or vibration.
2. The caulking should be as late as possible, and after it is as dry as possible, the seam tape should be pasted. It is best to wait for 24 hours after all the plates are loaded, so that the internal stress of the system has been greatly digested, and the deformation force exerted on the strengthening process of the caulking body will be smaller.
3. Due to the pulp-like filling of the putty in the seam of the plate, the volume will shrink when it is dry and hard. In order to avoid the dry and hard shrinkage of the putty after filling, the joint will have dark cracks. It is required that the filling putty construction must be carried out in two parts.
When the first caulking is carried out, the putty is pressed into the joint and compacted to ensure that it is firmly pasted. After the first putty is dry and hard, then make up the second putty and scrape it flat.
4. Paste mesh or kraft paper after the putty is dry and hard for the second time. The width of the mesh or kraft paper is in the range of 50mm to 60mm. After the mesh or kraft paper is all bonded and dry, it can be covered with ash.
Because it is not dry and hard, when soaked in the moisture in the putty, the mesh or kraft paper is easy to fall off, causing hollowing and cracks.
