Product Description
Gypsum based self-leveling compound KDO370A is a kind of high strength gypsum based dry mortar which includes high strength gypsum, redispersible polymer powder, cellulose ether and other active ingredient, is a high-tech environment -friendly product with advanced technology and formula refined. With fast hardening, people can walk on it after 4 hours, and 1-2 weeks later can do surface construction, it’s more convenient for workers to operate than traditional artificial leveling.

Key Properties
- It is easy to construct by stirring with water manually or mechanically.
- It has good self-leveling and smoothness.
- It has high compressive strength and wear-resistance, low shrinkage that is not easy to crack or generate delaminating and hollowing.
- It has rapid solidification, smooth surface that can be travelled after 4 hours. The plastic floor, carpet and tile can be paved on the surface after 1-2 weeks.
- It is environmental and non-toxic product.
Application range
- It is suitable for various raise the ground and leveling;
- It is suitable to apply for floor heat pipe backfill project and make the floor leveling.
- It is suitable for grand hotel, hall of airport, department stores, meeting room, exhibition center and so on.
Construction method
- The substrate must be clean, dry firm and no any residue;
- Mixed with water before construction by the specified equipment, be sure to strictly self-leveling compound: water 25: 7.5-8.0kg mixed, then use the transport pipe put the mixture into the construction area, a zigzag rake to move to a desired uniform thickness (thickness constructability 2-30mm).
- Before initial setting, use defoaming roller to exclude air which mixed in before.
Attentions
1. No excess water or it may decrease the compressive strength.
2. No strong wind and sun within 48 hours after construction.
Packing & Storage
A. Standard Packing: In 25kg paper bags inner with plastic woven bag.
B. Big Bag or other special packages are possible on request.
Store it in dry condition, and storage time should not exceed 12 months.
