🛠️ Preparation & Application Notes
Subfloor Preparation: Remove oil stains, dust, and loose debris. Grind uneven surfaces and vacuum thoroughly. Ensure the base is dry.
Priming: Apply water-based absorbent interface agent (for porous bases) or non-absorbent agent. Wait 2-6 hours to dry.
Mixing: Blend 25kg of compound with 6L clean water. Mix until smooth. Maintain a precise water-to-mortar ratio of 26%.
Application: Spread evenly using a notched trowel. Use a defoaming roller before setting to eliminate air bubbles.
