Homeowners and builders from DHA Karachi and Clifton to Hyderabad, Badin, and Sukkur battle a relentless construction problem known locally as kalar (salt efflorescence and rising dampness). Within months of painting a ground-floor wall, moisture wicked from saline soil crystallizes at the plaster surface, blistering expensive emulsions.
Why Repainting or Putty Alone Never Stops Kalar
Acrylic wall putty and ordinary primers sit on top of plaster like a thin plastic film. As capillary groundwater pressure pushes dissolved chlorides and sulfates upward, salt crystals expand up to 300% in volume, popping paint off the wall.
"To defeat wall kalar permanently, you must seal internal masonry capillaries before applying any decorative finish."
The 4-Step RHR Anti-Salinity Restoration Protocol
- Step 1 — Strip & Wire-Brush to Bare Masonry/Plaster: Scrape away all flaking paint, loose gypsum putty, and powdery salt deposits at least 2 feet above the visible damp line.
- Step 2 — Deep Capillary Sealing: Apply two saturating brush coats of RHR Patlo Sealer onto dry, dust-free plaster or concrete to block salt migration at the pore level.
- Step 3 — Crack & Plinth Barrier Protection: Seal hairline plaster cracks, sunken bathroom backing walls, and plinth joints with Readymix Patlo or two coats of Aqua Shield Waterproofing.
- Step 4 — Breathable Cladding or Finishing: For permanent luxury protection on ground-floor walls, clad directly with porcelain tiles using waterproof ReadyMix Tile Bond and New Stylish Grout.
