Dr. Fixit Newcoat
Heavy-duty, fibre-reinforced acrylic waterproof coating from Pidilite that builds a seamless 1 mm membrane over flat and sloping terraces — supplied and applied by Space Arc Engineering across Delhi NCR and pan-India.
What is it?
A single-component, water-based elastomeric acrylic coating with micro-fibres, applied in three colour-coded coats to form a 1–1.25 mm liquid waterproofing membrane.
Where is it used?
Flat and sloping RCC terraces, including refurbishment directly over sound brickbat coba, screeds and old acrylic coatings — no demolition needed.
Why use it?
200% elongation, 2 mm crack bridging and a breathable, UV-stable film that resists abrasion and fungus while taking normal foot traffic.
How is it applied?
Brush or roller over Dr. Fixit Primeseal primer; three undiluted coats at 2 m² per litre each, with glass-fibre mesh bedded in on larger roofs.
About Dr. Fixit Newcoat
Dr. Fixit Newcoat is Pidilite’s heavy-duty terrace waterproofing coating, formulated from resilient acrylic polymers, graded fillers, micro-fibres, weather-stable pigments and a fungicide carried in a water medium. Unlike thin decorative roof paints, it is engineered as a genuine liquid-applied membrane: three coats build a dry film of 1 to 1.25 mm, and each coat comes in a different colour so the applicator — and the client — can see that no patch has been skipped and the full thickness has actually gone down.
For Indian terraces its most practical strength is compatibility with what is already there. Sound brickbat coba, concrete screeds and tired acrylic coatings can be overcoated after localised repair and priming, keeping refurbishment cost, noise and debris to a minimum. Space Arc Engineering stocks Newcoat in 4 and 20 litre packs and fields trained applicator crews across Delhi NCR, so consultants get material and workmanship under one point of accountability — including the fibre-mesh-reinforced detail Pidilite recommends for larger roofs.
The technical insight
Newcoat works by pairing moderate tensile strength (2.6 N/mm², ASTM D 412) with very high extensibility — 200% elongation at break — so the cured film stretches across shrinkage cracks and thermally moving cold joints instead of tearing. Tested to ASTM C 836, it bridges static cracks up to 2 mm and cyclic movement of 1 mm over 10 cycles. Just as important is breathability: water vapour transmission of 19 g/m²/day lets residual slab moisture escape rather than blister the membrane, a common failure of vapour-tight coatings on damp Indian roofs. Micro-fibres raise tear resistance, and sandwiching a glass-fibre mesh between the first and second coats turns the film into a composite for large or crack-prone decks.
Where it is used
- Waterproofing of flat RCC terraces on residential buildings and housing societies
- Sloping and curved concrete roofs where sheet membranes are awkward to detail
- Refurbishment over existing sound brickbat coba without breaking it out
- Overcoating old concrete screeds and failed acrylic coatings after repair
- School, office and institutional roofs that see regular maintenance foot traffic
- Large commercial roofs using the glass-fibre mesh sandwich for higher movement capacity
- Periodic single-coat recoating of terraces previously treated with Newcoat
Key advantages
- High-build system — 1 to 1.25 mm dry film in three coats, far thicker than ordinary roof paints
- Bridges cracks up to 2 mm wide (ASTM C 836), absorbing normal slab movement
- Colour-coded coats give visible proof of coverage and thickness build-up
- Goes over sound brickbat coba and screeds, saving demolition time and debris disposal
- Abrasion-resistant film handles routine foot traffic without a protective screed
- Breathable film (19 g/m²/day WVT) reduces blistering risk on damp substrates
- Water-based and non-toxic; applies by brush or roller and recoats easily in later years
Limitations & considerations
- Rated for foot traffic only — not for vehicles or movement of machinery and equipment
- Must not be applied over expansion or moving joints; these need dedicated joint treatment
- Existing bitumen-based treatments must be completely removed by mechanical scarification first
- Needs a minimum roof slope of 1 in 100; ponding-prone flat spots must be corrected beforehand
- Never dilute with water, and never apply during rain; the primer needs a saturated surface-dry substrate
- Parapet walls need a separate coating such as Dr. Fixit Raincoat for a complete watertight envelope
Selection & best practice
Clean the terrace of dust, oil and loose material, cut hollow or damaged coba back to the mother slab, and reinstate it with a Dr. Fixit Pidicrete URP–cement slurry. Fill cracks wider than 5 mm with Crack-X or polymer-modified mortar; prime finer cracks with Primeseal and flood-fill them with Newcoat. Prime the whole deck with Primeseal diluted 2:1 with water (7–8 m² coverage) and let it dry 6–8 hours. Apply three undiluted coats of Newcoat at 2 m² per litre per coat, allowing 6–8 hours between coats; on large roofs, bed an open-weave glass-fibre mesh into the wet first coat and carry it over angle fillets. Give corners, outlets and protrusions two extra coats. Air-cure at least 7 days, verify roughly 1 mm dry film with test cuts every 200 m², then run a 48-hour ponding test at 50 mm depth.

Industry use cases
Housing societies & RWAs
Refurbishing leaking society terraces over old brickbat coba without demolition noise, debris lifts or prolonged disruption to residents.
Commercial buildings
Office and retail roofs where AC and plumbing technicians walk regularly — the abrasion-resistant film avoids a separate protective screed.
Schools & institutions
Water-based, non-toxic chemistry suits occupied campuses; three-coat application and recoating cycles slot neatly into vacation windows.
Industrial admin & utility blocks
Fibre-mesh-reinforced Newcoat handles long roof spans with cold joints and daily thermal movement across large plan areas.
Government maintenance contracts
Brush-and-roller application with colour-coded coats and measurable DFT verification supports departmental QA checks and rate-contract audits.

How we position Dr. Fixit Newcoat
Within the Dr. Fixit range, Newcoat sits above Newcoat Ezee — the economy option for smaller budgets — and works as a system with Primeseal primer, Pidicrete URP for coba repair, Crack-X for crack filling and Raincoat on parapet walls to close the envelope. Where a client wants heat reflectance along with waterproofing, we recommend Dr. Fixit Newcoat Sun Reflect. For high-movement decks, podiums or chemically exposed roofs, Space Arc also supplies PU liquid membranes such as Fosroc Nitoproof, and Sika liquid-applied systems — our engineers match the membrane to the deck, not the other way round.
