Scope of application:

  1. Construction Process
  2. Technical Indicators
  3. Technical Indicators

Anti-cracking mortar ratio: According to the anti-cracking mortar: water = 4:1 (weight ratio), mechanically stirred evenly, after standing for 5 minutes, it can be used after two times of stirring. It is advisable to use the configuration once in 2 hours.
Clear the original base layer soft and shelling parts, no floating soil oil, the base layer straightness deviation shall not exceed 3-5mm.
Pour the water into the container first, then add the powder and mix well, then apply directly with a special tool, the thickness is about 3mm.

- Construction performance: batch scratch-free
- Water resistance: no abnormality for 96 hours
- Standard bond strength: ≧ 1.0mpa
- Water resistant bond strength: ≧0.7mpa
-Theoretical amount: 3-4kg/m2 for bonding polystyrene board
- Dry time: 2 hours (25 ° C)
- Recoating time: 8 hours (25 ° C)
- Dry time: 24 hours (25 ° C)


- The verticality and flatness of the substrate should be determined before construction.
- Do not mix the dried paste with water.
- The best real-time effect is 45 minutes per deployment, the most common time is 2 hours.
- Do not apply outside of 5 ° C - 40 ° C or under rain.
