Dr. Fixit Raincoat Star
A tintable, elastic acrylic topcoat that keeps rain and UV off plastered exterior walls while bridging hairline cracks — doing the job of paint and waterproofing together.
What is it?
A single-component, water-based acrylic elastomeric coating for exterior walls, forming a flexible, tintable film that bridges hairline cracks up to 0.75 mm.
Where is it used?
Plastered and concrete exterior walls, parapets, chajjas and compound walls on homes, RWA blocks, villas and low-rise commercial buildings across Delhi NCR.
Why use it?
Ordinary exterior paint cracks with the wall and lets water track in behind it; Raincoat Star’s elastic film moves with hairline cracking instead of splitting.
How is it applied?
Brush or roller-applied in two coats over a clean, crack-filled surface — roughly 4.2–4.5 sqm/litre on smooth plaster, 3.7–4.2 sqm/litre on rough-cast walls.
About Dr. Fixit Raincoat Star
Dr. Fixit Raincoat Star sits in Pidilite’s Raincoat range of exterior wall coatings, built on acrylic elastomeric technology rather than the plain acrylic emulsion used in ordinary weatherproof paints. The difference shows after the first monsoon: a regular paint film is essentially rigid once cured, so when plaster on an exposed, sun-baked Delhi NCR facade develops the fine surface cracks that are almost inevitable, the paint cracks with it and water finds a way in. Raincoat Star’s film stays elastic, stretching over hairline movement up to 0.75 mm instead of splitting — the entire point of calling it a waterproofing coating rather than just weatherproof paint.
For Space Arc’s clients — RWA committees repainting ageing towers, homeowners doing up a villa elevation — that distinction matters commercially as much as technically. It’s tintable across 1000+ shades, so one product replaces the primer-plus-paint-plus-waterproof-coat sequence. It is not a fix for structural cracks, active leaks or ponding water on terraces; those need a repair mortar or a dedicated horizontal membrane, with Raincoat Star reserved for vertical exterior walls.
The technical insight
The chemistry is a straightforward acrylic elastomeric binder that dries to a continuous, flexible film: the polymer stays mobile enough to stretch across a moving hairline crack without tearing, then recover through summer heat and monsoon soaking. Dr. Fixit publishes the crack-bridging limit (0.75 mm) and coverage rate, but not independent dry-film-thickness, elongation or standard-compliance figures the way an engineered coating like Fosroc’s Dekguard range does. For a decorative-grade wall coating that’s normal; for a specifier needing documented EN 1504 or ASTM numbers for a submittal, it’s a gap worth flagging.
Where it is used
- New plastered RCC exterior walls before first monsoon exposure
- Repainting over sound, prepped, ageing cement paint or older Raincoat-family finishes
- Parapet walls and terrace-boundary walls exposed to driving rain
- Chajjas, sunshades and other projecting elements prone to water wash
- Compound and boundary walls with no roof protection
- RWA and society tower block facade repainting cycles
- Villa and bungalow exterior elevations needing a decorative tinted finish
- Budget hotels, schools and clinics wanting low-maintenance painted exteriors
Key advantages
- Elastic film bridges hairline cracks up to 0.75 mm instead of cracking with the wall
- Doubles as decorative finish and waterproofing coat, tintable across 1000+ shades
- UV and weather resistant, formulated for exterior exposure through heat and monsoon
- Anti-algal formulation keeps facades cleaner for longer between repaints
- Brush or roller applied, no specialised spray plant needed
- Manufacturer-backed performance warranty on the coating itself
- Two-coat system keeps labour and material planning simple
- Pack sizes from under a litre to 20 litres suit both patch jobs and full facades
Limitations & considerations
- Crack-bridging tops out at 0.75 mm; wider or structural cracks need filling and repair first, not more coats
- Not for horizontal ponding-water areas like terraces or sunken slabs — those need a dedicated membrane
- Performance depends entirely on surface prep; dust, algae or friable old paint left in place causes early peeling
- Brush/roller application on large facades is labour-intensive and sensitive to skipped spots or under-thinning
- Manufacturer literature cites both a 7-year performance warranty and a 10-year waterproofing warranty for the same line — confirm exact terms in writing at purchase
- Independent third-party spec data (elongation, DFT, standard compliance) isn’t published the way it is for engineered protective coatings
Selection & best practice
Treat Raincoat Star as a system, not a can of paint: rake out and fill hairline cracks, remove algae/chalking, let the surface dry fully, and apply two full coats at the specified coverage rather than stretching one can further — under-application is the single biggest reason elastomeric coatings fail early on Delhi NCR facades. Avoid applying just before or during rain, and keep it to vertical walls; route terraces and ponding-water areas to a dedicated membrane instead. Space Arc registers the manufacturer warranty against every job.

Industry use cases
RWA and Group Housing Societies
Facade repainting on ageing towers where hairline plaster cracking has started letting monsoon water into flats below parapet and sill lines.
Independent Villas and Bungalows
One product covers the decorative tinted finish and the waterproofing brief together.
Institutional and Low-rise Commercial
Budget hotels, clinics and schools wanting a low-maintenance exterior that outlasts plain emulsion.
Renovation and Repainting
Recoating sound, well-prepped old cement paint without a full re-plaster.
Compound and Boundary Walls
Unshaded perimeter walls taking direct rain wash-off and UV with no overhang protection.

How we position Dr. Fixit Raincoat Star
Within Dr. Fixit’s range, Raincoat Star sits above the standard Dr. Fixit Raincoat as the crack-bridging, higher-spec option — for pure decorative weatherproofing with no cracking history, base Raincoat is the more cost-effective call. It’s a wall product only: terraces and ponding-water areas belong to Dr. Fixit’s horizontal lines such as Roofseal and Pidiproof LW+. Where a project moves into RCC structural-protection territory — flyovers, coastal facades, commercial parapets needing documented crack-bridging class and CO2/chloride resistance for a submittal — Fosroc’s Dekguard Elastic is the more defensible spec, publishing EN 1504-aligned elongation and carbonation data that Raincoat Star’s consumer sheet doesn’t attempt to match.
Fosroc Dekguard Elastic — Specify Dekguard Elastic instead of Raincoat Star when the project needs documented EN 1504 crack-bridging class and anti-carbonation performance data for an engineer’s submittal — typical on flyovers, coastal facades and RCC structures rather than routine home or society repainting.
