Application Areas
- Cement grandstands
- Indoor and outdoor sports courts
- Underground garages and parking structures
- Industrial cement floors
Note: For any waterborne coating system applied to cement substrates, it is strongly recommended to use ST400 as the sealing primer. Failure to do so may result in peeling, delamination, or cracking.
Key Features
- Waterborne and eco-friendly: Non-toxic and low odor; safe for transport and on-site use
- Excellent sealing and penetration: Strengthens substrate bonding and system durability
- Superior adhesion: Achieves adhesion test grade 0–1
- Indoor-outdoor versatility: Compatible with a wide range of cement-based environments
Instructions for Use
- Preparation and Mixing
- Thoroughly mix Components A and B before use.
- If needed, clean water may be added (no more than 10%) to adjust viscosity.
Substrate Requirements
- The substrate must be sanded, dry, clean, and free of standing water.
- Construction environment: temperature ≥5°C, relative humidity <80%.
- Avoid application during rainy weather.
Prohibitions
- Strictly avoid contact with gasoline, thinners, solvents, or oil-based substances during construction.
Recoating
- Topcoat can be applied at least 4 hours after the primer is dry to the touch.
- The primer may appear slightly colored during application but will dry to a transparent finish. Minor color variation is normal.
