⚡ Quick Answer
Terrace waterproofing in India involves 5 key steps: clean and repair surface → apply primer → apply 2 coats liquid membrane (Dr. Fixit Roofseal) → lay 50mm screed concrete → optional tile/brick bat finishing. Total cost: ₹60–120/sqft professionally.
Step-by-Step Terrace Waterproofing Process
1
SURFACE PREPARATION — Remove all old treatments, clean the slab thoroughly, chip away loose concrete and fill cracks with polyurethane sealant or Dr. Fixit Crack X. Ensure the surface is completely dry.2
SLOPE CORRECTION — Ensure 1:100 slope (1 inch drop per 100 inches length) towards drains. Wrong slope is the #1 cause of water pooling and leakage. Use M15 cement mortar to create slope if needed.3
PRIMER APPLICATION — Apply Dr. Fixit Primecote or equivalent to the entire surface including parapet walls (1 foot up). Let dry for 6 hours.4
LIQUID MEMBRANE — Apply 2 coats of Dr. Fixit Roofseal or Fosroc Reebol by brush/roller. Each coat: 1.2 kg per sq metre. Wait 24 hours between coats. Take membrane 6 inches up all parapet walls.5
PROTECTION SCREED — Pour 50mm thick M20 grade cement concrete over the cured membrane. This protects the membrane from foot traffic and UV rays. Cure for 7 days.6
OPTIONAL FINISHING — Lay Kota stone, terrace tiles, or brick bat china mosaic on top of screed for a neat finish. This also adds thermal insulation.⚠️
Critical Mistakes
Never apply waterproofing on wet surface (wait 3 sunny days after rain). Never skip the primer coat. Never terminate membrane at the slab edge — always take it up the parapet wall minimum 6 inches.
