A, caulking gypsum
The main caulking gypsum is mainly made of fine gypsum powder, which is used for caulking and leveling between gypsum boards and nail holes, and is also suitable for repairing indoor wall holes, gaps, trunking and local places with poor flatness.
Changsha Hengkang Building Materials Co., Ltd. is fully equipped with putty powder for wall protection, natural nano dry powder coating, reactive dry powder mirror art coating (silk screen printing) and reactive dry powder texture art coating.
Features: early strength, fast hardening, fire prevention, heat preservation, sound insulation, automatic adjustment of indoor temperature. At the same time, the construction workability is good, the bonding strength is high, and it is not easy to empty and crack, and the construction speed is fast.
Fine gypsum powder is mainly used for caulking gypsum, with fine aggregate, weak hardness, poor elasticity and relatively poor water resistance, which is easy to peel and crack in large areas. Therefore, it is only suitable for plasterboard joints, yin and yang angle leveling repair, steel wire slotting or local repair.
Second, paint plaster.
Plastering gypsum is a new product promoted by the state to replace cement mortar, which is more environmentally friendly and economical. It has the advantages of cement strength, health and environmental protection, durability, strong adhesion, no powdering, no cracking, no hollowing and no powder dropping, convenient use and cost saving. At present, it is widely used for plastering interior walls of buildings.
Disadvantages of plastering gypsum: generally, the walls of new houses are poured with concrete, and the flatness error of the walls is large. Although the error of plastering gypsum is qualified, such a wall will definitely delaminate and crack after a period of time, and the wall skin will even fall off. So painting plaster is not an ideal choice.
