Everbuild 503 SBR Bond 5L

Everbuild® 503 Premium SBR Bond – 5 L

Latex-based, water-resistant bonding agent, primer, and admixture supplied in a 5 L container. Formulated for application in areas subject to humidity, dampness, or water contact, it enhances mortar, render, and screed performance through improved adhesion, durability, and flexibility.

Key benefits

• Improves water resistance and water-vapour permeability in cementitious mixes.
• Forms a reinforcing polymer that boosts long-term flexibility and toughness.
• Contains anti-foam to maintain consistent mix density.
• Provides excellent adhesion to dense substrates such as concrete, steel, and tiles.
• Delivers enhanced frost resistance and freeze-thaw stability (passes five cycles at −10 °C).
• Reduces surface dusting and allows thinner application layers.
• High resistance to salt permeation and suitable for chemically harsh environments (e.g., dairy parlours).

Typical applications

• Used as an admixture in mortar, screeds, and render for improved durability.
• Serves as a bonding agent to enhance substrate adhesion.
• Acts as a primer or sealer in tiling applications, including on wooden or asphalt floors.
• Recommended for both internal and external use—unaffected by wet conditions.

Application information

• Aqueous styrene-butadiene emulsion polymer base; white liquid with anti-foam properties.
• Viscosity: approximately 100 cPs (RVT 1/10 rpm).
• Minimum film-forming temperature: 0 °C.
• Freeze-thaw resistant; stable through multiple freeze cycles at –10 °C.
• Yield estimate: 1.2 L covers about 1 m² at 12 mm thickness.

Product details

• Pack size: 5 L jerrycan (also available in 2.5 L, 25 L, and 1000 L IBC versions).
• Density: 1.020 kg/L.
• Colour: White.
• Manufacturing shelf life: 12 months in sealed containers—store at moderate temperatures; thaw slowly if frozen and stir before use.

Good to know

Not suitable for exterior coloured renders not intended for overpainting due to potential UV-related discoloration. Always confirm compatibility with the latest technical data sheet for optimal results.
