Choose a coating system for your building’s environment. Explore Aqua Paints solutions for coastal salinity, heavy rainfall and high heat or UV exposure.
Environmental exposure zones illustrated in the presentation.
The right system starts with the right assessment.
Buildings and structures in high-salinity or coastal areas, high-rainfall or high-moisture areas, and areas with high heat or UV exposure require coating systems selected according to the environmental exposure. Consider local climatic conditions, substrate type, any history of moisture or salt deposits and contamination, and the structure’s intended service conditions.
Bangladesh’s buildings face three major environmental stresses associated with global climate change.
Coastal & salinity
Salt deposits, contaminated masonry and corrosion.
Heavy rainfall
Water penetration, dampness and coating deterioration.
High heat & UV
Painting systems for heat-exposed exterior and interior walls.
01 / COASTAL & SALINITY
Protection for coastal and salt-prone buildings
Satkhira (Shyamnagar), Khulna (Dumuria, Koyra), Bagerhat (Sarankhola), Chattogram (Banshkhali) and Cox’s Bazar (Moheshkhali) fall within Bangladesh’s officially identified coastal zone.
Efflorescence / white salt depositsSalt-contaminated masonry and concreteSteel corrosion and rusting
Beyond coastal areas: Anti-efflorescence treatment may also be applied where bricks or masonry contain soluble salts or show a tendency toward efflorescence, irrespective of geographic location.

04 / HEAVY RAINFALL
Painting systems for moisture-prone regions
For Sylhet, Chattogram, Barishal and Khulna divisions, and other high-rainfall or moisture-prone regions.
Rainfall context
The presentation reports that Bangladesh recorded 75.7% above-normal rainfall in April 2026, with Sylhet receiving 603 mm during that month. In May 2025, Sylhet recorded 156 mm in three hours.
What heavy rainfall does to buildings
Heavy rainfall can lead to water penetration, moisture retention, material deterioration and coating failure.
Water penetration into porous masonry and concrete.
Dampness and moisture retention.
Water ingress through cracks and weak areas.
Accelerated corrosion or rusting of steel.
Coating deterioration and premature failure.
