Asian Paints SmartCare SmartCare Damp Proof Advanced
A fibre-reinforced elastomeric membrane that primes, waterproofs and heat-shields RCC roofs, terraces and exterior walls in one white, brush-applied system.
What is it?
A single-pack, fibre-reinforced elastomeric acrylic membrane. Asian Paints builds it around resilient acrylic polymer plus reinforcing synthetic (polyester) fibres, so the cured film behaves less like a paint and more like a thin, seamless rubber-ish sheet stretched across the slab.
Where is it used?
Building roofs, terraces, parapets, sunshades and exterior vertical walls. It’s also approved to go over existing IPS flooring, sound brick-bat coba, or old cementitious waterproofing that’s still firmly bonded — useful on retrofit terraces where a full tear-off isn’t in the budget.
Why use it?
The fibre reinforcement gives it real crack-bridging ability across hairline movement, it’s rated to resist up to 7 bar of positive hydrostatic pressure, and the high-sheen white finish knocks up to 10°C off terrace surface temperature in peak sun — a genuine comfort benefit on Delhi NCR’s top floors through May-June.
How is it applied?
Self-primed: a first coat diluted 33% with water goes on by brush, followed by two full-strength coats by brush or roller at 4-6 hour recoat intervals. On vertical walls, Space Arc typically carries an Apex or Ultima exterior emulsion topcoat over it for UV protection and colour.
About Asian Paints SmartCare SmartCare Damp Proof Advanced
Asian Paints markets Damp Proof Advanced as a 3-in-1 system — primer, waterproof coat and heat shield — and on the technical merits that’s a fair summary rather than pure ad copy. Underneath the white, high-sheen finish is an elastomeric acrylic film loaded with synthetic fibres, which is what lets it stretch and bridge hairline movement across a slab rather than cracking straight through the way a rigid cementitious coating would. It’s the middle option in Asian Paints’ SmartCare waterproofing family: more reinforcement than the base SmartCare Damp Proof, less specified than SmartCare Damp Proof Ultra, which makes it the default recommendation Space Arc gives for a straightforward RCC terrace or parapet that isn’t dealing with severe structural cracking or ongoing active leaks.
For Delhi NCR specifically, the two properties that matter most in practice are the crack-bridging and the heat reflectance. Most top-floor terrace problems here aren’t dramatic — they’re hairline shrinkage cracks that open up a little further every summer-to-monsoon cycle, and a plain paint-grade coating just tears along that line within a season or two. The fibre reinforcement is what buys extra life against that specific failure mode. Separately, the high-sheen white finish measurably cuts surface temperature in peak sun, which homeowners notice directly as a cooler top-floor room in May and June, independent of whether the roof was actually leaking. Where we’d steer a client elsewhere is genuinely wide or active structural cracks, or terraces used for rainwater harvesting — this product isn’t warranted for that, and the fix there is a repair-first approach (SmartCare Crack Seal or a polymer-modified mortar) before any membrane goes down, exactly as the manufacturer’s own datasheet specifies.
The technical insight
What separates Damp Proof Advanced from a plain elastomeric wall coating is the fibre reinforcement suspended in the acrylic film. Asian Paints’ own datasheet describes it as acting like a steel mesh inside the membrane — it doesn’t stop a crack from moving, but it distributes the stress across the fibre network instead of letting it concentrate at one point and tear the coating. The datasheet’s own crack-bridging figure is a modest 1mm on horizontal surfaces, tested to Asian Paints’ internal method, so we treat this as a fine-crack membrane rather than a structural-movement solution; anything wider gets pre-treated with SmartCare Crack Seal or a polymer-modified mortar before the membrane goes on, exactly as the datasheet specifies. The anti-carbonation rating (R-value 275 at 207-micron dry film thickness) is the other technical detail worth flagging to clients who ask “why waterproof a roof that’s already leak-free” — a dense, well-cured elastomeric film also slows CO2 and chloride-ion ingress into the concrete below, which matters for rebar corrosion protection on older RCC terraces even before any active leak shows up. Specific gravity of 1.25 and solids content of roughly 55-60% by weight are fairly typical for this coating class; they mainly tell an applicator how much material needs to be bought against the stated coverage rate, and why “stretching” the material below the forced coverage figure quietly shortens service life even when the roof looks fine on handover day.
Where it is used
- RCC roof slabs and open terraces exposed to monsoon ponding and peak summer sun
- Parapet walls and sunshades (chajjas) prone to hairline thermal cracking
- Exterior vertical masonry walls, usually finished over with an Apex/Ultima topcoat
- Retrofit waterproofing over sound, firmly-bonded old brick-bat coba (BBC)
- Retrofit waterproofing over existing IPS (Indian Patent Stone) terrace flooring
- Overcoating aged but intact cementitious waterproofing after a patch adhesion test
- Balcony decks and machine-room / lift-room roof slabs
- Terrace upturns into rainwater drain outlets (minimum 6 inches inside the pipe, per datasheet)
Key advantages
- Single-pack, brush/roller applied — no on-site mixing ratios to get wrong
- Polyester fibre reinforcement adds tear and abrasion resistance over a plain acrylic film
- High-sheen white finish reflects heat, cutting terrace surface temperature by up to 10°C
- Rated to resist up to 7 bar of positive hydrostatic pressure
- Anti-carbonation property helps slow CO2/chloride ingress that corrodes rebar over time
- Can be overcoated directly on sound existing IPS, BBC or cementitious systems — no mandatory tear-off
- Documented Asian Paints warranty (up to 8 years, terrace and vertical use per current datasheet)
- Available from 1-litre to 20-litre packs, so it scales from a balcony patch job to a full terrace contract
Limitations & considerations
- Datasheet crack-bridging figure is 1mm on horizontal surfaces — active or wider cracks need Crack Seal or polymer-modified mortar repair first, not the coating alone
- White-only finish; there’s no tinted or coloured option if the client wants the terrace to match a scheme
- Strict application window of 5°C-35°C with no rain — during Delhi NCR’s short pre-monsoon prep season this compresses the usable application days
- New masonry needs a full 28-day cure before coating, which can clash with fast-track handover schedules
- Explicitly not recommended for rainwater-harvesting collection surfaces per the manufacturer
- Performance depends on hitting the datasheet’s forced coverage rate — thinning it out to cover more area is the single most common cause of early failure we see on site
Selection & best practice
Start with the substrate, not the tin: hammer-test the terrace for hollow patches, strip every trace of old bitumen coating (wire brush plus a high-speed water jet works better than brush alone), and let new plaster cure a full 28 days before anything goes on it. Fill cracks up to 3mm with SmartCare Crack Seal; anything wider gets a proper polymer-modified mortar repair. Prime with the first coat diluted 33% with water, then apply two full-strength coats by brush or roller, respecting the 4-6 hour recoat window and the datasheet’s litre-per-square-metre coverage rate — do not stretch the material to save cost, it’s the fastest way to void the practical waterproofing life even if the surface looks fine at handover. Embed SmartCare Joints Tape at every corner and construction joint on horizontal surfaces before the final coat, confirm the roof has a working drainage slope so water doesn’t sit and test its patience against the membrane, and carry the coating at least 6 inches inside every drain outlet. On tiled or glossy cementitious surfaces, run SmartCare Terrace Tile Primer first — Damp Proof Advanced won’t grip a slick tile face on its own. Wash off algal or fungal growth every six months to keep the reflective finish, and the heat-reduction benefit, working as intended.

Industry use cases
Residential (independent houses, builder floors)
Pre-monsoon terrace waterproofing on exposed RCC roofs, where the heat-reduction benefit is as much a driver for top-floor bedroom comfort as the leak-stopping itself.
Residential retrofit
Overcoating an aged but sound brick-bat-coba terrace showing early seepage signs, avoiding a full BBC removal and re-lay.
Low and mid-rise commercial buildings
Parapet, sunshade and terrace waterproofing bundled into a façade repainting cycle alongside Apex/Ultima exterior emulsion.
Institutional (schools, small offices)
Budget-conscious terrace refurbishment where a single-pack, low-skill application keeps contractor labour and site supervision simple.
Builder / developer new construction
Standard post-handover terrace waterproofing system on new RCC slabs once the mandatory 28-day cure is complete, ahead of parapet coping and railing work.

How we position Asian Paints SmartCare SmartCare Damp Proof Advanced
Within Asian Paints’ own SmartCare waterproofing range, Damp Proof Advanced is the mid-tier terrace membrane — a step up from the base SmartCare Damp Proof on fibre reinforcement, and a step below SmartCare Damp Proof Ultra for projects that need a heavier-duty system. It’s designed to be used alongside SmartCare Crack Seal for crack repair, SmartCare Joints Tape for corner and joint reinforcement, and SmartCare Terrace Tile Primer where the existing surface is tiled or glossy — Space Arc stocks the full companion set so a terrace job doesn’t stall waiting on one missing tin. For clients who are already standardised on Fosroc elsewhere on a project, or who specifically want a colour-coded, coat-by-coat build-up they can visually audit during application, Fosroc Brushbond Roofguard is a genuine like-for-like alternative in the same fibre-reinforced acrylic terrace-coating category — Space Arc supplies and applies both, so the choice comes down to brand standardisation and site preference rather than a meaningful performance gap.
Fosroc Brushbond Roofguard — Specifiers already standardised on Fosroc systems, or who want a coat-by-coat colour change for on-site thickness verification during a quality audit, often choose Brushbond Roofguard instead of Damp Proof Advanced for the same terrace-coating role.
