ICI Dulux Aquashield Pre Treatment Coat — Waterproofing Primer in Karachi
ICI Dulux Aquashield Pre Treatment Coat is the first step in the Aquashield waterproofing system. Available at Saify Paint House, your authorized ICI Dulux Paints dealer in Karachi since 1999, it deeply penetrates and seals the surface before waterproofing basecoats are applied.
Karachi’s monsoon season and year-round humidity make waterproofing essential on roofs, walls, bathrooms, and any surface prone to seepage — and this pre-treatment stage is what determines whether the waterproofing system above it actually bonds and performs.
Why Waterproofing Fails Without This Stage
The most common reason a waterproofing job fails is not the topcoat — it is skipping or rushing the preparation beneath it. Concrete and masonry are naturally porous and often carry surface contamination — dust, laitance, loose material, and residual construction debris — that prevents a waterproof basecoat from bonding properly.
Pre Treatment Coat penetrates into that surface and seals it, binding loose material and creating a stable, consistent base. Applied directly, a waterproof basecoat over an unsealed or contaminated surface may look fine on application day, but adhesion failure shows up later — as blistering, peeling, or, worst of all, water finding its way through the very system meant to stop it.
This matters more on roofs and older surfaces than anywhere else. Roof slabs accumulate years of dust, algae, and surface degradation before a waterproofing project begins, and pre-treatment is what gives the system a genuine chance of adhering through a full monsoon season rather than failing at the first heavy rain.
Skipping this stage to save time or cost is the single most common reason waterproofing projects need redoing within a year or two.

Recommended Applications
ICI Dulux Aquashield Pre Treatment Coat is used ahead of any Aquashield waterproofing system:
- Flat and sloped roofs before waterproof roofcoat application
- Exterior walls prone to water seepage
- Bathrooms and wet areas before interior waterproofing
- Basement walls requiring damp protection
- Older roofs and walls with weathered or contaminated surfaces
- Any concrete or masonry surface ahead of an Aquashield basecoat
Suitable for concrete, cement render, and masonry surfaces in sound condition.
Surface Preparation & Application
The surface must be clean, dry, and free from dust, loose material, oil, grease, and algae or fungal growth. Pressure washing or thorough brushing is often necessary on roofs and exterior walls that have accumulated years of surface contamination.
Remove any loose, flaking, or degraded material back to a sound surface. Treat algae and fungal growth before applying the pre-treatment coat — sealing over active growth traps it beneath the system.
Repair any structural cracks or damage before waterproofing begins. Waterproofing coatings bridge minor surface issues but do not substitute for structural repair where the substrate itself has failed.
Stir thoroughly before use. Apply by brush or roller, following the coverage rate and drying time specified on the product label. Allow the pre-treatment coat to dry fully before applying the next stage in the Aquashield system — proceeding too early compromises the bond between layers.
Completing the Aquashield System
Pre Treatment Coat is stage one of a complete waterproofing sequence.
