Liquid Applied Radon, Gas and Vapour Barrier
Newton 902 is a single component, high performance, elastomeric liquid rubber membrane specifically designed to provide a radon, gas and vapour barrier to vertical and horizontal surfaces. It is a water based compound, formulated on a styrene-butadiene copolymer.
Newton 902 can be used as the primary gas and vapour barrier to new and existing walls and floors and can be used below the insulation as the vapour control layer within a warm roof specification.
Newton 902 can be easily applied to a large variety of different surfaces such as concrete, mortar, brick, Insulated Concrete Framework (ICF), ceramics, steel, zinc and aluminium to provide a continuous membrane.
Key Benefits
• A 0.7mm thick (dry film) coating provides an effective gas and vapour barrier when applied to most clay or cementitious based construction materials
• Effective radon barrier – independent certification
• Excellent adhesion – bonds to porous and non-porous substrates
• Flexible – Resistant to movements and fissures in substrates
• Easily applied with a brush, roller or airless spray
• Non-toxic
• Will withstand temporary light trafficking
• Cannot be punctured as fully bonded
• Easily repaired by locally over-coating
• Can be painted, plastered or screeded over
• Rapid drying. In good conditions, two coats can be applied in the same day
• Easily applied to damp and “green” substrates
• Newton 902 has good chemical resistance to gasoline, sodium hydroxide, calcium chloride, de-icing salts and effluent.
Typical Applications
• Radon, Gas & Vapour barrier to walls and floors of concrete, masonry and brick substrates
• Vapour control layer below insulation in warm roof builds
• Vertical waterproofing membrane when used with Newton 410 Geodrain vertical drainage membrane
• As a primer for concrete and steel prior to adhesion of Newton Waterseal Tape, Waterseal Rope and Overtape within Newton System 500 installations
• Simple to apply DPM to existing damp floors
• Window reveal DPM used in conjunction with Newton System 500. Broadcast builders sand onto the still tacky 902 to provide a key for plasters and renders
