The fastest and best way to deal with the joints of gypsumboard ceilings

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.

Caulk (Lafarge Knauf and the like) mix the joints with glue, and pay attention to the spatula to be flattened. Check that all seams are caulked and wait until they are dry before roughly treating the lower surface, Lafarge and other brand bandages are soaked in water and covered with white latex paste, be sure to use a good bandage of the brand, otherwise it is very troublesome to rework. After drying, you can make putty as a whole, and the decoration company will ask for another caulk covering on the bandage, and the effect will be better.

Originally, gypsum board absorbs water, and then evaporates, and naturally shrinks; So when the paint is finished for two or three days, it is not obvious, but after a week or two, there is a problem.

In fact, the best way is to use nylon cloth 5 6cm wide, the woven texture of nylon cloth to form the warp and weft in both directions, and cut along the warp and weft sides when cutting, not obliquely cut. The base treatment is clean and level; This keeps the surface of the latex paint free of cracks for a longer period of time. If you have more questions, you can click on ID to consult.
