Overview Owatrol E-B is a penetrating paint additive and bonding primer that enhances the performance of water-based masonry and interior paints. Ideal for use on unstable, chalky, or powdery surfaces, it stabilises porous or crumbling substrates, such as render or brickwork, while eliminating the need for a separate primer. E-B creates a strong bond between the substrate and topcoat, improving paint adhesion and durability without altering the original colour.
