Zinsser AllWeather Exterior Masonry Paint is a high-performance, solvent-based coating designed to withstand the harshest weather conditions. Formulated for long-term decoration and protection, it delivers excellent resistance against cracking, blistering and flaking, while protecting against heavy rain and severe weather.

This self-priming paint can be applied to bare or previously painted masonry, bonding directly to the surface without the need for a separate primer. With its flat matt, breathable finish and excellent colour retention, AllWeather provides a lasting solution for exterior walls, even when applied in challenging conditions. It dries quickly, remains showerproof in just 20 minutes, and can be applied in temperatures as low as -5°C. Making it a true all-year-round masonry paint.
