Dr. Fixit Raincoat WPC
A flexible, ready-to-use waterproof coat that keeps monsoon seepage off plastered exterior walls without an extra priming step.
What is it?
A water-based, polymer-elastomeric exterior wall coating from Dr. Fixit that forms a flexible waterproof film over plastered masonry and doubles as a primer for the topcoat over it.
Where is it used?
Exterior plastered brick, block and RCC walls, parapets and sunshades on homes and low-rise buildings, applied fresh or during a repaint.
Why use it?
Ordinary paint films are rigid and crack as walls move seasonally; Raincoat WPC’s elastomeric film stretches instead, and carries a 5-year Dr. Fixit waterproofing warranty.
How is it applied?
Ready to use, no dilution, on a clean, sound, dry plastered surface – brushed or rollered on as a basecoat before the final exterior emulsion or texture coat.
About Dr. Fixit Raincoat WPC
Exterior walls in most Indian cities take a beating ordinary paint wasn’t built for – a hot, UV-heavy summer that shrinks plaster, then weeks of driving monsoon rain finding every hairline crack and pinhole. Dr. Fixit Raincoat WPC is built for that cycle: a water-based, polymer-elastomeric coating for plastered brick, block or RCC exterior walls that forms a continuous flexible film, so it moves with small seasonal wall movement instead of cracking open and letting water track in behind the paint.
It also does two jobs in one pass. Dr. Fixit positions it as a universal basecoat that primes and waterproofs together, cutting a separate priming step before the final exterior emulsion or texture coat. It’s ready to use with no dilution, covers roughly 4.2-4.7 sq.m per litre per coat depending on plaster porosity and texture, and comes in 1, 4, 10 and 20 litre packs for anything from a touch-up to a full facade. Applied and maintained to spec, it carries a 5-year Dr. Fixit waterproofing warranty.
The technical insight
The reason this outperforms a standard exterior emulsion on a cracking wall is film mechanics, not colour. Dr. Fixit rates the dry film at around 100% elongation, laid down noticeably thicker than a standard paint coat – which is what lets it bridge hairline plaster cracks up to 0.5mm: the film stretches across the gap and stays continuous instead of tearing along the crack edge, so water can’t use it as an entry point. That 0.5mm figure covers fine hairline shrinkage cracking only, not wider settlement or structural cracks, which need proper crack-repair mortar or sealant first.
Where it is used
- Waterproofing plastered brick, block or RCC exterior walls, fresh or during a repaint
- Renovation basecoat over ageing, chalking or hairline-cracked facades
- Parapet walls, chajjas and sunshades that take direct, driving rain
- External walls of homes and villas in high-rainfall belts – coastal Konkan, the Northeast, hill towns
- Terrace parapet and boundary wall exteriors exposed to constant weathering
- Priming-cum-waterproofing basecoat under most exterior emulsion or texture systems
- New-build facades needing one product that primes and waterproofs before final paint
- Retrofit jobs where internal damp patches trace back to a failing external wall
Key advantages
- Ready to use, no dilution or site mixing – faster application, fewer batching errors
- ~100% film elongation moves with the wall through seasonal expansion and contraction
- Bridges fine hairline cracks up to 0.5mm before they turn into leak paths
- Doubles as primer and waterproof coat, cutting a step out of the usual sequence
- Backed by a 5-year Dr. Fixit waterproofing warranty (terms apply)
- Nationwide Pidilite/Dr. Fixit dealer and applicator network for consistent quality and warranty support
- Compatible as a basecoat under most exterior emulsions and texture finishes
- Familiar water-based application by brush, roller or spray – no specialised crew needed
Limitations & considerations
- Crack-bridging tops out at 0.5mm hairline cracks – not a fix for wider shrinkage or structural cracks, which need repair first
- Coverage (4.2-4.7 sqm/litre/coat) swings with plaster porosity, so old or textured walls can eat more material than a flat estimate suggests
- Built for wall facades, not expansion joints, roof decks or below-grade/water-retaining structures
- The 5-year warranty is conditional on following the specified prep, coats and system – easy to compromise under site pressure
- Water-based, so it needs a dry, rain-free window and shouldn’t go onto damp or green plaster – awkward right before monsoon
- Published data covers coverage, elongation and packs but not every figure (coats, SG, cure schedule) – pull the current TDS before quoting
Selection & best practice
Treat surface prep as the job, not a formality. The wall should be clean, sound and free of loose paint, dust, algae or chalking, with hairline cracks and holes filled and cured before the first coat – the coating bridges fine movement, it doesn’t hide bad prep. Apply by brush, roller or spray at the coverage and coats specified in the current TDS, respect the recoat interval, and avoid application if rain is forecast or the plaster hasn’t cured. Where the warranty matters, register the job through an authorised Dr. Fixit applicator and keep site records – batch numbers, coats applied, weather – for any future claim.

Industry use cases
Residential – independent houses
Re-waterproofing an ageing facade on a 15-year-old house before a repaint, to stop seepage stains reappearing inside each monsoon.
Apartment/RWA exteriors
Basecoat on a mid-rise building’s external walls ahead of a society repaint cycle, chosen for elongation and warranty over a plain primer.
Coastal and high-rainfall regions
Villa exteriors in Konkan, coastal Odisha or the Northeast, where driving rain and salt air make ordinary exterior paint fail early.
Renovation contractors
Standard basecoat on repaint jobs with hairline map-cracking but no structural distress, to bridge cracking before the new topcoat.
Parapets and sunshades
Targeted application on chajjas and terrace boundary walls taking the brunt of wind-driven rain, ahead of a full repaint.

My wall has active seepage – will this stop it?

How we position Dr. Fixit Raincoat WPC
Within Dr. Fixit’s own range, Raincoat WPC sits alongside Raincoat Classic as part of the same elastomeric exterior-wall family – Space Arc stocks both, and the right pick depends on wall condition, crack profile and budget, worth a quick call with our technical team rather than a brochure guess. Outside the Dr. Fixit stable, genuine equivalents are other branded decorative waterproof exterior paints, not industrial coating systems. The comparison gets real on exposed RCC facades needing anti-carbonation protection rather than a decorative finish – bridges, exposed columns, coastal structures with reinforcement risk – where Fosroc’s Dekguard Elastic is a legitimate alternative built for that heavier, higher-movement job rather than a standard plastered residential wall.
Fosroc Dekguard Elastic — A specifier would choose Dekguard Elastic over Raincoat WPC on exposed RCC facades needing anti-carbonation and chloride protection with heavy-duty crack bridging (up to 6mm static movement, EN 1062-7 Class IV) – bridges, columns, coastal structures – rather than on a standard plastered residential wall, which is Raincoat WPC’s home turf.
