REFERENCE / DATA

Facts & figures

Every specification figure this site relies on, in one place: layer thicknesses in millimetres, curing periods in days, the Indian Standards each system works to, measured Mumbai rainfall by observatory, and ward and pincode data for 50 localities. Sourced, not estimated — and where a figure is not confirmed it says so rather than showing a number.

PROVENANCE

Where these numbers come from

Specification figures — thicknesses, curing periods, lap widths — are industry-standard values for the system described, not claims about any one project. A project specification always overrides them.

Rainfall is the long-period average from the IMD observatory that governs each zone. Ward and pincode data is administrative fact. Company statistics that we have not verified are shown as “to be confirmed” rather than estimated — which is why some cells below are empty rather than impressive.

CURING

Curing periods

The figure most often compressed on site, and the one that decides whether a cementitious system survives its second monsoon.

Curing periods by system
SystemCuring requirement
Terrace WaterproofingCementitious layers are water-cured for a minimum of 7 days, and brick bat coba for 14–21 days. This is the single most frequently compressed part of a terrace job, because curing produces nothing visible. A coba that was cured for four days instead of fourteen looks identical at handover and cracks within two monsoons.
Basement WaterproofingCementitious tanking is kept damp and cured for 7 days minimum. Injection resin is left 24–72 hours before the leak is re-inspected, since polyurethane continues to react and expand after injection and a path that looks sealed at the end of a shift is not yet proof of anything.
Bathroom WaterproofingCementitious coatings are cured for 3–7 days depending on the product before the pond test. Tiling does not begin until the barrier has fully cured — laying tiles onto a green coating traps moisture and compromises the bond it has yet to develop.
Toilet Waterproofing3–7 days cure before pond testing, and full cure before tiling. Returning a WC to service before the barrier has cured is a common cause of early failure in occupied buildings where the room is needed back quickly.
Brick Bat Coba Waterproofing14–21 days of continuous water curing. Brick bat coba is a cementitious system of substantial thickness and it gains its strength and impermeability slowly. There is no additive that substitutes for curing time.
China Mosaic Waterproofing7 days of water curing after grouting. The reflective white surface also reduces solar heat gain into the slab, which matters directly to the comfort of the top-floor flat beneath it.
APP Membrane WaterproofingNo curing period as such — the bond is formed as the bitumen cools, and the membrane is effectively serviceable once cool. The critical window is instead the torching itself: too little heat and the lap never fuses, too much and the sheet's reinforcement is damaged.
SBS Membrane WaterproofingTorch grades are serviceable once cool. Self-adhesive grades develop their full bond over 24–48 hours and should not be loaded or trafficked during that window.
HDPE Membrane WaterproofingNo cure period for the membrane itself. The governing constraint is that it must remain undamaged between installation and the pour, which is why the pre-pour walkover is treated as a formal hold point rather than a courtesy.
TPO Membrane WaterproofingNo curing period. Weld quality is the entire quality question, which is why trial welds and full seam probing carry more weight here than on any other system.
Polyurea WaterproofingGels in seconds and is typically walkable within an hour, reaching full properties within 24 hours. That speed is the reason it suits shutdown windows and fast return to service — but it also means preparation errors are sealed in permanently and immediately.
PU GroutingFoaming resin reacts within seconds to minutes on contact with water, and cures fully within hours. The meaningful interval is the 24–72 hour observation afterwards, since sealing one path can raise pressure and open another nearby.
Injection GroutingCementitious grouts gain strength over 7 days; epoxies reach handling strength within 24 hours and full properties within about 7 days. Load should not be reapplied to a structurally injected member before the specified strength is reached.
Overhead Water Tank (OHWT) WaterproofingCure strictly to the manufacturer's stated period — commonly 5–7 days for cementitious potable linings — followed by flushing. This period is not compressible: an under-cured potable lining is both a performance and a water-safety problem.
Underground Water Tank (UGT) WaterproofingInternal linings are cured for the manufacturer's full stated period before filling, then flushed. Where ground water is present throughout, dewatering is maintained until the cure is complete rather than switched off at the end of the working day.
Swimming Pool WaterproofingCured per the product datasheet before filling and before tiling — commonly 5–7 days for cementitious immersion systems. A pool returned to service early is the most common cause of an early relining.
Podium WaterproofingLiquid systems cure to a walkable state within hours and to full properties within 24–72 hours per the datasheet. Landscaping and paving follow only after the flood test has passed and protection is in place.
Lift Pit WaterproofingCementitious tanking is kept damp and cured for 7 days. Dewatering continues throughout the cure — switching the pump off overnight mid-cure floods a partially cured layer and undoes the work.
External Plaster & PaintingRender is water-cured for 7 days and allowed to dry before priming. Applying primer to green render traps moisture and causes the paint system to blister — which then gets blamed on the paint.
Building RestorationRepair mortars are water-cured for 7 days minimum. Protective coatings follow only once repairs have cured and dried. Restoration is a sequence, and compressing any part of it undoes the parts already completed.
Chemical CoatingCure time and full chemical resistance are product-specific, commonly 24 hours to handling and up to 7 days for full chemical service. Returning a bund to service before full chemical cure is a frequent and expensive error.
Cement Based CoatingWater-cured for 7 days minimum. The system is rigid, so it performs well on stable substrates and will crack with a substrate that moves — which is a selection question, not an application one.
Elastomeric CoatingTouch-dry within hours, with full film properties developing over about 7 days. Recoat intervals between coats must be respected — overcoating too early traps solvent or water and blisters the film.
Acrylic CoatingTouch-dry within hours; full properties over several days. Acrylic coatings are decorative and protective but have limited crack-bridging capability — where the substrate has live hairline cracking, an elastomeric grade is the correct choice instead.
Solvent Based CoatingHandling cure typically within 24 hours and full chemical resistance in up to 7 days. In occupied buildings a clearance period is agreed before reoccupation, because odour persists well past touch-dry.
Food Grade Coating for Water BodiesCured strictly to the manufacturer's stated period — commonly 5–7 days for cementitious potable linings — followed by flushing. This period is not negotiable regardless of how urgently the tank is needed back.
Base Coat WaterproofingNot cured in isolation — the base coat is designed to be overlaid while still green so the layers bond monolithically. If the follow-on layer is delayed beyond that window, the base coat must be cured properly and then re-keyed with a bonding agent.
Shahabad Ladi Waterproofing7 days of water curing. Joints are the maintenance item on a Shahabad terrace and should be inspected and re-pointed periodically rather than left until water has been entering for a season.
FRP Lining WaterproofingCure time is resin- and temperature-dependent, typically 24 hours to handling and up to 7 days for full chemical resistance. Putting a tank back into chemical service before full cure will damage a lining that would otherwise have lasted for years.
Integral Waterproofing Compound (Admixture)Extended water curing per IS 456 principles. The permeability benefit of an integral compound is realised through the cured pore structure, so a poorly cured mix with an admixture can perform worse than a well-cured mix without one.
Crystalline WaterproofingKept damp for at least 3 days, with the full reaction developing over a longer period. Because the crystals form inside the concrete rather than as a surface film, the treatment cannot delaminate or wear off — and it reactivates whenever water returns, which is what gives it its self-healing behaviour on fine cracks.
Box Type WaterproofingNo cure period for sheet systems. The governing constraint is continuity: the barrier must remain unbroken and undamaged from the blinding, under the raft, up every wall and to its sealed termination above ground level.
Bentonite WaterproofingNo cure period. The system activates on contact with groundwater after backfill. Its useful property is that it re-seals around minor punctures and settlement movement, which suits below-grade work where nothing can be inspected later.
Bituminous Felt WaterproofingNo cure period — the system is serviceable once cool. Its life is governed by UV exposure, which is why the surface dressing is a functional requirement rather than a finish.
Lime Terracing (Lime Concrete)Long, slow, damp curing over weeks, because lime sets by carbonation. Both the beating and the curing periods are the labour discipline that determines the outcome, and neither can be compressed to meet a programme.
Mud Phuska WaterproofingMortar layers water-cured for 7 days. The mud layer's real contribution is thermal — it noticeably reduces heat gain into the top floor, which is why the system persists on low-rise buildings despite the dead load.
Silane-Siloxane Water Repellent TreatmentCures within 24 hours to a fully invisible finish. Service life is product-specific and finite, and reapplication is due when the water-bead test stops showing beading — a simple check any building manager can carry out.
Refuge Area WaterproofingLiquid systems are left to cure per the product datasheet before the ponding test — typically 24–72 hours. Screed and finish layers are water-cured for 7 days.
Expansion Joint TreatmentSealants skin within hours and cure through their depth over several days, depending on the product and the joint depth. The joint should not be subjected to significant movement or traffic until it has cured through.
Tape Based TreatmentAdhesive tapes develop full bond over 24–48 hours and should not be loaded or wetted during that period. The encapsulating coat is applied per its own cure schedule.
Solvent Based TreatmentCures as the solvent flashes off, typically within 24 hours, with ventilation maintained throughout rather than only during application.
Chequered Tiles Work7 days of water curing after grouting, before the surface is opened to regular traffic.
IPS Screeding Work7–14 days of continuous water curing. IPS is a plain cementitious topping with no additive that compensates for a curing period that was cut short.
External Plaster Work7 days of continuous water curing, then allowed to dry before any coating system is applied over it.
Column & Beam RCC WorkRepair mortars are water-cured for 7 days minimum. Repairs cured poorly shrink away from the parent concrete at the bond line, which is where the next failure starts.
Carbon Wrapping (RCC Strengthening)Epoxy systems reach handling strength within 24 hours and full properties in about 7 days. The strengthened member should not be loaded to its new design capacity until full cure is reached.
External PaintingTouch-dry within hours, full properties over about 7 days. Painting should not begin on render that has not both cured and dried, however tight the programme is.
ACP Sheet WorkNo curing period. The governing constraints are the substrate condition behind the cladding and the panel's fire performance, both of which are settled before installation begins.

NOT PUBLISHED

What is deliberately absent from this page

Three things a page like this would normally carry, and why they are not here.

No rates. Cost bands show “to be confirmed” until a confirmed rate card exists. A published rate that cannot survive a site visit misprices the market and creates quote disputes.

No star rating or review count. There is no verified review corpus to average, and inventing one is a manual-action risk as well as a lie.

No failure index. An aggregated index of inspection findings by locality would be genuinely valuable and no competitor has one — but it requires real survey records, which do not yet exist in a form we can publish. It will be built from actual data or not at all.

NEXT STEP

Need a figure that is not here?

If you are preparing a tender or a specification and need something this page does not cover, ask. We would rather send you the datasheet than have you work from an estimate.
