APPLICATION THICKNESS
Our premium gypsum-based self-leveling mortar offers adaptable thickness options ranging from a finely-tuned 3mm to a solid 30mm in a single construction phase.
Subfloor Preparation
- Eliminate oil stains, dust, loose debris, and old coatings.
- Sand down uneven patches and remove loose concrete.
- Maintain a dry base, completely free of puddles.
- Apply appropriate interface agents (LG660 for absorbent or LG670 for non-absorbent surfaces).
Construction Process
1. Priming: Clean the base and apply a suitable primer. Allow 2-6 hours to dry before self-leveling application.
2. Mixing: Add 25kg of compound to 10L of clear water. Mix until lump-free. Spread evenly using a notched trowel to the desired thickness.
3. Finishing: Use a defoaming roller to remove air bubbles before setting. For efficiency, pumps with 20-40 L/min flow rates can be used.
Important Notes
- Temperature range: 5°C to 30°C with low relative humidity.
- Follow the water-to-material ratio (41%-44%) with precision.
- Use mixed material within 20 minutes to prevent premature setting.
- Avoid skin and eye contact; protect the surface from water and heavy impacts during curing.
Storage & Transportation
Store in a dry, well-ventilated space away from direct sunlight. Handle with care to avoid packaging damage during transport.
Frequently Asked Questions
Q: What is the ideal application thickness for K30 self-leveling mortar?
A: The thickness is highly adaptable, ranging from 3mm for fine leveling to 30mm for more substantial backfill requirements in a single application.
Q: How much water should be mixed with one 25kg bag?
A: For optimal consistency and strength, mix 25kg of dry powder with approximately 10 to 11 liters of clean water (a ratio of 41% to 44%).
Q: How long does it take for the floor to be ready for use?
A: The initial drying time is between 24 and 48 hours. However, full compressive strength (15-18 MPa) is typically achieved after 28 days of curing.
Q: Can K30 be used with underfloor heating systems?
A: Yes, K30 is excellently suited for underfloor heating backfill as it ensures uniform heat distribution and high thermal efficiency.
Q: Is the K30 self-leveling compound environmentally friendly?
A: Absolutely. It is formulated with eco-friendly additives, is pollution-free, and poses no hazards to the public or the environment.
Q: What should be done if the substrate is very absorbent?
A: For absorbent substrates, we recommend applying a water-based absorbent interface treatment agent (like LG660) to ensure proper adhesion and prevent air bubbles.
