Lightweight plastering gypsum

Lightweight plastering gypsum mortar is a newer, more environmentally friendly and more economical product that is promoted by the country instead of cement mortar. It not only has the strength of cement, but also is healthier and more environmentally friendly than cement. It is durable, has a large bond, and is not easy to powder. No cracking, no hollowing, no powder falling, etc.
The light-weight plastering gypsum produced by Qicai Bangyuan Mortar is mainly made of light-weight materials. It is easy to use and saves costs. There are more advantages as follows:
1. Good bonding performance. After cleaning the base of the wall, it can be directly use.
2. The energy-saving effect is good, which can meet the energy-saving design requirements of indoor walls.
3. It has better fire performance.
4. It has the function of micro-expansion, which can prevent the appearance of fine cracks on the wall surface, and there will be no hollowing or cracking after use.
Product parameters

Specifications	Material properties	construction application	Packaging storage
ZC light type is suitable for indoor wall and ceiling plastering, suitable for rooms with standard air and humidity	Loose density about 800kg/m³	Mechanical spraying, manual plastering	25kg bag
Spread rate about 850kg/m³	The water powder volume ratio is about 1:2	Store in a cool and dry place with a shelf life of 6 months
The construction time limit is about 120min	The finished surface is rough surface and smooth surface

Scope of application
ZC light-weight plastering gypsum is suitable for general plastering projects on the interior walls and ceilings of buildings, except for indoor wet areas such as kitchens, bathrooms, and balconies. ZC lightweight plastering gypsum is suitable for plastering and leveling of most base materials (air-entrained concrete, lightweight partition wall slats, bricks, concrete, etc.). The conventional plastering thickness of ZC lightweight plastering gypsum is 6mm-25mm, the minimum thickness of the plastered surface is 6mm, and the total thickness of the ceiling plastering should be less than 10mm.
Product features
1: High tensile bonding strength, suitable for a variety of bases, well matched with light wall materials, not easy to hollow out and crack after construction;
2: No need to pre-water the wall before plastering in normal construction environment, The construction environment has been significantly improved;
3: The construction saves materials and labor, and its weight is only one-third of the traditional cement mortar;
4: The construction is fast, and the final setting time and curing time are short;
5: The verticality and flatness of the finished surface are high, and local It is easy to repair;
6: It can adjust the indoor air humidity, assist heat preservation, and improve indoor comfort;
7: The net space for indoor use can be increased due to the reduction of construction thickness, and sound insulation can be reduced;
8: Greatly enhance the fire resistance of the interior;
