ICI Dulux Aquashield Waterproof Roofcoat — Roof Waterproofing in Karachi
ICI Dulux Aquashield Waterproof Roofcoat is a heavy-duty waterproof coating specifically designed for flat and sloped roofs. Available at Saify Paint House, your authorized ICI Dulux Paints dealer in Karachi since 1999, it provides long-lasting protection against rain penetration and water pooling.
The final stage in the Aquashield system for roof applications, it is formulated to withstand the most demanding waterproofing challenge any surface on a building faces — constant, direct exposure to standing and flowing water.
Why Roofs Need a Dedicated Waterproofing Product
A roof faces a category of exposure that no wall experiences. Rain does not run off a flat roof the way it runs down a wall — it pools, sits, and slowly finds every weakness in the surface beneath it. Sloped roofs fare better but still channel large volumes of water across the same coated surface repeatedly through a monsoon season.
This sustained hydrostatic pressure, rather than brief contact, is what a heavy-duty roofcoat is built to resist. Ordinary exterior paint, even good quality wall paint, is not formulated for standing water and will fail within a season or two under roof conditions.
Karachi’s monsoon compounds the challenge. Roofs here take the full force of concentrated seasonal rainfall, often over consecutive days, and any weak point in the waterproofing shows up immediately as an interior leak — frequently in a location some distance from the actual failure point, since water travels along the underside of a slab before finding a way through.
A properly applied heavy-duty roofcoat, on a correctly prepared surface, is what prevents that scenario. It is not a product to economise on, given that the cost of a failed roof waterproofing job includes not just redoing the roof but repairing the interior damage the leak caused.
ICI Dulux is backed by AkzoNobel, a global leader in paints and coatings with over 200 years of innovation. Full technical specifications for this product are available on the official Dulux Pakistan website.

Surface Preparation & Application
Roof preparation determines whether this coating performs for years or fails within a season. This is not a surface to prepare quickly.
The roof must be clean, dry, and free from dust, loose material, moss, algae, and any standing debris. Pressure washing is typically necessary to remove years of accumulated grime before treatment can begin. Allow the surface to dry completely before proceeding — any trapped moisture beneath the coating undermines the whole system.
Repair all cracks, joints, and structural defects before waterproofing. Pay particular attention to junctions — where the roof meets parapet walls, around pipe penetrations, and at drainage outlets. These junction points are where the great majority of roof leaks originate, and they need reinforcement beyond the flat coating alone.
Ensure the roof has adequate drainage and slope toward outlets. Waterproofing coatings resist water penetration; they do not compensate for a roof design that allows water to pool indefinitely rather than draining away.
Apply ICI Dulux Aquashield Pre Treatment Coat first and allow it to dry fully — this stage is essential on roofs given the scale of surface contamination roofs typically carry.
Stir thoroughly before use. Apply by brush, roller, or squeegee, following the coverage rate and number of coats specified on the product label. Pay extra attention to junctions, corners, and penetrations, building additional thickness at these vulnerable points. Allow full drying between coats, and avoid application when rain is forecast during the curing period.
Completing the Aquashield System
Waterproof Roofcoat is the roof-specific finish in the complete Aquashield sequence.
Always begin with ICI Dulux Aquashield Pre Treatment Coat to seal and prepare the surface.
For exterior walls facing the same seasonal exposure, ICI Dulux Aquashield Flexible Waterproof Basecoat addresses movement and weather. For interior wet areas, ICI Dulux Aquashield Interior Waterproof Basecoat completes protection throughout the property.
