Anonymous users2024-01-23The joints above the gypsum board ceiling are scraped with caulking gypsum, and the caulking gypsum dries off the powder, whether the caulking gypsum is not good.
The joints scraped with caulking gypsum in the gaps above the gypsum ceiling, the caulking gypsum dried up and the powder was not good for the caulking gypsum: it could only be reworked. The reasons for depowdering are as follows:
1.In the actual construction, in order to save materials and save trouble, workers often add water and stir the thickened gypsum mortar or semi-dry floor ash again. Because the gypsum has been hydrated to a considerable extent before adding water, the gelling ability of Li Qingzhen's slurry is limited after re-adding water and stirring, which is also the main reason for the weight of depowdering.
If it is mixed with new powder, it will also cause fast setting and greatly shorten the working time of the slurry. 2.Under the premise that the gypsum is late and the dosage is sufficient, the direct cause of depowdering is often that the gypsum cannot be fully hydrated and cannot produce sufficient gelling capacity.
First, fix the light steel keel or wooden keel, adjust the level, and connect the gypsum board to the keel with self-tapping screws, and the gypsum board can be cut out according to the size required by the ceiling. I hope my answer can help you.
This is mainly due to the acidic substances contained in the gypsum board and the substances in the putty powder embedded in the batch. Resulting in yellowing. For this kind of gap, it is generally recommended to use elastic putty to treat it, or to wet the sticker tape directly with caulking paste.
If a slight settlement causes a crack, the clay inside the crack can be pulled out. If the gap is too small and almost closed, the gap should be cut to about 4 mm, and then smoothed with caulking clay, pasted with grid or paper tape along the gap, scraped white, sandpaper, and painted latex paint. >>>More
We all use plaster and putty glue to caulk.
Gypsum powder is mixed with white latex or polyethylene glue, but there are anti-cracking products on the market that do not need to be adjusted, but the price is relatively high. And the effect is not as good as gypsum powder, fill the gaps after adjusting evenly, and then paste gauze tape on the outside (kraft paper is better than gauze tape, there is a new type of fiberglass mesh belt), and then scrape putty.
