📏 Thickness & Prep
Thickness: Range from 3mm to 8mm in a single, seamless sweep.
Subfloor Preparation:
- Clean surface of oil, dust, and loose debris.
- Sand uneven ground to remove loose concrete.
- Ensure base is dry and free of puddles.
- Use LG660 for absorbent or LG670 for non-absorbent substrates.
🛠️ Application Method
1. Priming: Apply appropriate primer. Wait 2-6 hours until semi-dry.
2. Mixing: Mix 25kg compound with 5L water using a mechanical mixer until smooth. Distribute with a notched trowel.
3. Finishing: Use a defoaming roller before setting to eliminate air bubbles.
Important Notes: Construction temperature 5°C to 30°C. Maintain strict water-mix ratios. Apply within 20 minutes of mixing.
❓ Frequently Asked Questions
Q: What is the recommended thickness for K80 application?
A: K80 can be applied from 3mm to 8mm thickness in a single application.
Q: How long is the working time once mixed?
A: The material remains workable for approximately 30 minutes at 20°C; it should be applied within 20 minutes to avoid premature solidification.
Q: What is the water-to-mortar ratio?
A: The optimal mixing ratio is 1:5 (approx. 5.5L to 6L of water for a 25kg bag).
Q: Can K80 be used in industrial environments?
A: Yes, its high compressive strength (45Mpa at 28 days) and wear resistance (BS8204AR1) make it ideal for heavy commercial and industrial settings.
Q: What is the fire resistance rating?
A: K80 has a fire resistance rating of A1, the highest level of non-combustibility.
