BioBase Liquid Applied DPM is a ready-to-use, water-based, single-pack damp-proof and gas-resistant membrane for above-ground applications, available in 5L and 20L. It forms a flexible and elastic coating once cured and is suitable for solid floors, embedded timbers and floor-to-wall junctions. It can be applied to damp (but not wet) substrates by brush, roller or spray, and is touch-dry in around one hour. Provides a barrier to damp, radon, carbon dioxide and methane.\u003c\/p\u003e\n\u003ch3\u003eKey benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDamp-proof barrier\u003c\/li\u003e\n\u003cli\u003eRadon, methane \u0026amp; CO₂ gas barrier\u003c\/li\u003e\n\u003cli\u003eWater-based single pack (ready to use)\u003c\/li\u003e\n\u003cli\u003eEasy brush, roller or spray application\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTypical applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSolid concrete floors and screeds (cured at least 28 days)\u003c\/li\u003e\n\u003cli\u003eEmbedded timbers and floor-to-wall junctions\u003c\/li\u003e\n\u003cli\u003eLow-level wall application up to the DPC (typically under 100mm)\u003c\/li\u003e\n\u003cli\u003ePreparation under laminate floors\u003c\/li\u003e\n\u003cli\u003eRefurbishment and new-build projects\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplication\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eStir well before use\u003c\/li\u003e\n\u003cli\u003eApply 2 coats by brush, roller or airless spray, each coat 0.55 L\/m²\u003c\/li\u003e\n\u003cli\u003eApply the second coat at right angles to the first once touch-dry (approx. 1 hour); do not leave more than 24 hours between coats\u003c\/li\u003e\n\u003cli\u003eMinimum 0.6mm dry film thickness for vapour barrier performance\u003c\/li\u003e\n\u003cli\u003eDo not apply below 7°C; ensure good ventilation\u003c\/li\u003e\n\u003cli\u003eColour change from blue to black indicates drying\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eLimitations\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eNot a trafficable\/wearing surface\u003c\/li\u003e\n\u003cli\u003eMust not be exposed to direct sunlight externally\u003c\/li\u003e\n\u003cli\u003eNot suitable for negative water pressure (e.g. basements)\u003c\/li\u003e\n\u003cli\u003eDo not directly bond wood flooring to BioBase-coated concrete\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical data\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCoverage (vapour barrier): 4.5 m² per 5L\u003c\/li\u003e\n\u003cli\u003eCoverage (general purpose DPM): 7–9 m² per 5L\u003c\/li\u003e\n\u003cli\u003eResistance: 20m head (positive pressure)\u003c\/li\u003e\n\u003cli\u003eWater vapour permeability: \u0026lt; 4 g\/m²\/24h @ 25°C \/ 75% RH\u003c\/li\u003e\n\u003cli\u003eRadon barrier at 2mm dry film; methane resistance 10× LDPE\u003c\/li\u003e\n\u003cli\u003eTensile strength 4 N\/mm²; elongation at break 350%\u003c\/li\u003e\n\u003cli\u003eStorage 5–35°C, dry; shelf life 18 months\u003c\/li\u003e\n\u003cli\u003eTested to BS3177, BS8204, BS903 and CP102:1973\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0913\/3903\/0865\/files\/BioBase_TDS.pdf?v=1788258632\" target=\"_blank\" rel=\"noopener\"\u003e\u003cstrong\u003eDownload the BIOKIL.
