Dulux Weathershield Masonry Paint - Concrete Grey - 5L

This paint is designed for exterior masonry surfaces such as render, concrete, brickwork, pebbledash, and exterior cement boards. Always ensure the surface is clean, dry, and structurally sound before application.

Typically, Dulux Weathershield Masonry Paint is touch dry in 2-4 hours and can be recoated after 4-6 hours. However, drying times can vary depending on temperature, humidity, and ventilation. Always refer to the product label for the most accurate information.

A primer is highly recommended for bare, new, or very porous masonry surfaces to ensure optimal adhesion, an even finish, and to maximize the paint's durability. For chalky or friable surfaces, a stabilising solution is essential.

To activate the Weathershield Promise, you typically need to register your purchase and application details with Dulux within 6 months of buying the paint. Full terms and conditions apply and can be found on the Dulux website or product packaging.

No, Dulux Weathershield Masonry Paint is specifically formulated for exterior use and is not recommended for interior applications. Use an appropriate interior paint for indoor projects.

Thanks to its 'Stay Clean' technology, the paint resists dirt and mould. For general cleaning, gently wash the surface with a soft brush or sponge and clean water. Avoid using harsh chemical cleaners or abrasive scrubbing, which could damage the paint film.

This often indicates poor surface preparation. Ensure all loose material, dirt, and previous flaking paint are removed. For porous or chalky surfaces, a suitable masonry primer or stabiliser should be applied before painting to create a sound base.

Apply the paint in even, consistent coats without overspreading or overworking. Ensure brushes and rollers are fully loaded but not dripping. Allow adequate drying time between coats. Avoid painting in direct sunlight or strong winds which can cause rapid drying and unevenness.

The 'Stay Clean' technology prevents mould within the paint film, but existing mould spores must be thoroughly eliminated before painting. Clean the surface with a proprietary fungicidal wash, rinse well, and allow to dry completely. If the problem persists, investigate underlying damp issues in the wall.

Paint colour can vary slightly depending on surface texture, lighting, and number of coats. Ensure you've applied at least two full coats. For critical colour matching, purchase enough paint from the same batch number and always test a small, inconspicuous area first.
