Product Description

EVERBUILD® 503 Premium SBR Bond is a versatile, high-performance bonding agent designed to enhance cement mixtures exposed to humidity, dampness, and water contact. It forms a reinforcing polymer that improves long-term durability, flexibility, and water resistance of renders, screeds, and mortar mixes.
This advanced formula boosts adhesion to a wide range of surfaces—including dense concrete, steel, and tiles—while allowing for thinner application layers. Containing anti-foam agents, it ensures optimal mix density and workability.

Key Features:

• Significantly improves adhesion on various substrates
• Enhances water and water vapor resistance
• Increases flexibility and toughness of cement-based mixes
• Allows thinner application sections without compromising strength
• Reduces surface dusting and water-to-cement ratio
• Provides high resistance to salt permeation and chemicals
• Freeze-thaw stable with improved frost resistance
• Ideal for both interior and exterior applications, including humid or wet environments

Common Uses:

• As an admixture for mortars, screeds, and renders
• As a bonding agent for cementitious layers
• As a primer/sealer in tiling and flooring
• To boost flexibility of tile adhesives on wood or asphalt floors
• Suitable for demanding environments such as dairy parlours

EVERBUILD® 503 Premium SBR Bond offers reliable performance in challenging conditions, making it the smart choice for professional builders and DIYers alike.
