Give your exterior walls the perfect foundation with Dulux Weathershield Prime Coat, a premium acrylic-based exterior primer specially developed to improve paint adhesion, surface durability, and overall finish quality. Available at Dulux Newtown, your trusted authorized Dulux dealer in New Town, Kolkata, this high-performance primer creates a strong bonding layer between masonry surfaces and exterior topcoats for long-lasting protection.

Its advanced acrylic formulation delivers superior adhesion, excellent whiteness, and outstanding coverage while effectively sealing porous plaster surfaces. The built-in Anti-Alkali and Anti-Efflorescence properties help prevent peeling, flaking, chalking, and salt deposits, ensuring your exterior paint remains vibrant and durable for years.

Dulux Weathershield Prime Coat also improves topcoat coverage, enhances colour uniformity, and provides a smoother paint finish, making it the ideal primer for new exterior plastered walls. If you're searching for the best exterior primer in Kolkata, premium acrylic primer for exterior walls, or a high-performance wall primer, Dulux Weathershield Prime Coat is the perfect solution for residential, commercial, and industrial projects.

Allow freshly plastered walls to cure for at least 12 weeks before applying the primer. Ensure the wall surface is clean, dry, and free from dust, grease, chalk, algae, fungi, loose particles, and flaking paint. For best results, the wall moisture content should be below 10% before application.

Dilute 1 litre of Dulux Weathershield Prime Coat with up to 1 litre of clean water and mix thoroughly until a uniform consistency is achieved. Apply one even coat using a brush, roller, or spray equipment and allow it to dry for 3–4 hours before applying the exterior topcoat.

If wall putty is part of the painting system, apply one coat of primer before the putty application and another coat after the putty has dried and been sanded. Following the recommended application method ensures excellent adhesion, improved topcoat performance, and long-lasting protection for exterior walls.
