It is best to use latex paint to ensure the flatness of the wall plasterboard.

Gypsum board ceiling attention is that there can be no joints in the corner, to use the whole board, otherwise the paint will be done in the later period of time will definitely crack! The other is to pay attention to the expansion joints! It is recommended to compare a few more materials to compare service, quality, after-sales and reputation!

Light steel keel gypsum board ceiling.

Gypsum board is made of plaster as the main raw material mixed with additives and fibers, which has the properties of light weight, heat insulation, sound absorption, non-flammability and sawability. Gypsum board is combined with a light steel keel (pressed from galvanized thin steel) to form a light steel keel gypsum board. There are many types of light steel keel gypsum board ceilings, including paper gypsum board, decorative gypsum board, fiber gypsum board, and hollow gypsum slats.

There are a variety of specifications on the market. At present, there are many light steel keel gypsum board ceilings used as partition walls, and relatively few are used for modeling ceilings.

Gypsum board ceiling, mostly used in commercial space, generally used 600x600 (mm, the length of the unit is not indicated in the project, the unit is mm) specifications, there are bright bones and dark bones. The keel is usually aluminum or iron.

The first problem to pay attention to in gypsum board ceiling is the flatness of the ceiling surface, followed by the cracking of gypsum board joints. The requirement for flatness is to check with a two-meter ruler, and the error is not more than 2mm, and the main reason for this index is the keel, as well as the boom and gypsum board. The boom is not vertical, the strength is not enough, the keel arrangement is too thin, the connection is not firm, etc., will cause the ceiling surface to be uneven.

The cracking situation is mainly caused by the improper use of seam agent and seam strip, at present, manufacturers generally have special seam materials, but the price will be slightly higher. If the air is dry, cracking can be detected in about a month. At present, the market has better quality Lafarge, Dragon, Taishan brand, etc., and the major building materials markets are sold.
