Water Based
Master Sealer is a water-based acrylic primer and sealer developed to enhance adhesion on porous roof tiles and masonry surfaces. This advanced product is designed to form a strong bond between the substrate and any subsequent coatings, laying the groundwork for long-lasting protection and visual appeal.
Its standout feature is the ability to penetrate highly porous materials deeply. Whether you’re working on exposed roof tiles or weathered masonry, Master Sealer helps seal and stabilise the surface. This ensures that topcoats adhere evenly and remain intact, even under harsh weather conditions.
By creating a sealed surface it prevents the premature loss of topcoat due to excessive absorption, saving both time and product. The result is a reliable and consistent finish that withstands hot, cold, or wet climates. This makes Master Sealer ideal for roofing and exterior applications where long-term durability matters.
When paired with NuTech topcoats, such as TileFlex or NXT Cool Zone, it becomes part of a comprehensive protective system. Together, these coatings offer outstanding resistance to UV, water, and environmental wear. It is suitable for both residential and commercial use, particularly in areas prone to extreme weather conditions.
Application is quick and easy with standard tools, and cleanup is simple thanks to its water-based formulation. It also features low VOC levels, making it safer for applicators and the environment.
If you’re preparing a porous tile or masonry surface, this acrylic primer provides the strength, sealing power, and adhesion support necessary for high-performance coatings.
