Masonry:
- Substrate: Clean and firm; remove dust, oil, and debris. No pre-wetting needed for blocks with low-to-medium water absorption.
- Mixing: Powder to water ratio = 1 : 0.18 – 0.20. Mix for 3 minutes until smooth and lump-free.
- Application: Apply mortar to both bonding surfaces. Press blocks firmly; maintain joints at 10 – 15 mm.
- Curing: Hardens at room temperature. Water curing is required in high temperatures or dry conditions (humidity < 30%).)
Plastering)
- Alignment: Use plumb bobs and level lines to ensure wall squareness. Set plastering beads (screeds) every 1.2 – 1.5 m.
- Substrate: Clean and firm. Pre-wet high-absorption substrates (e.g., AAC blocks) but ensure no standing water. For low-absorption concrete, roughen the surface or apply a primer.
- Finishing: After 1 – 3 hours of drying, level and compact with a float. Perform polishing for smooth finish requirements.
