Solvent-Free, Two-Part Epoxy Waterproofing System for Concrete and Masonry Biokil Crown Epoxy Tanking is a high-performance, two-component, solvent-free epoxy coating formulated to provide a durable, chemical- and water-resistant barrier to internal concrete and masonry surfaces. Suitable for tanking basements, retaining walls, inspection pits, and plant rooms, it cures to form a tough, impermeable membrane that resists both moisture ingress and negative hydrostatic pressure. It also serves as a protective coating in areas subject to high humidity or chemical exposure. Key Features & Benefits Water & Vapour Barrier: Provides long-lasting protection against water ingress, damp, and vapour transmission. Solvent-Free Formula: Low odour and safe for use in confined or sensitive environments. Chemical Resistance: Resistant to a wide range of mild acids, alkalis, and cleaning chemicals. Negative & Positive Pressure: Suitable for areas exposed to water pressure from either side of the structure. Easy to Apply: Can be applied by roller, brush, or airless spray in two coats. Product Details Type: Two-component solvent-free epoxy resin system Components: Part A (resin) and Part B (hardener) Colour: Grey (other colours available upon request) Coverage: Approx. 3–4 m²/kg for two coats, depending on substrate porosity Pot Life: Approx. 40 minutes at 20°C Full Cure: 5–7 days Packaging: Typically supplied in 5kg or 10kg kits SKU: BCEPXTANK5 / BCEPXTANK10 Application Instructions Surface Preparation: Surfaces must be sound, clean, and free from dust, oil, or contaminants. Slightly damp substrates are acceptable. Mixing: Add Part B (hardener) to Part A (resin) and mix thoroughly with a slow-speed drill and paddle mixer. First Coat: Apply evenly using a brush or roller. Allow to cure for 12–18 hours depending on conditions. Second Coat: Apply perpendicular to the first. Ensure full coverage and membrane thickness. Protection: Avoid water exposure during curing. Can be overlaid with screeds, renders, or tile finishes. Limitations Do not apply at temperatures below +5°C or in damp, unventilated conditions during curing. Not suitable for external UV-exposed surfaces unless overcoated with a protective finish. Health & Safety Contains epoxy resins and hardeners — may cause allergic reactions or skin irritation. Always wear gloves, goggles, and respiratory protection. Refer to the product’s Safety Data Sheet (SDS) before use.
