Multithane X is a high-performance, moisture-curing polyurethane waterproofing membrane engineered for long-term protection across a wide range of residential, commercial, and industrial applications. As a cross-linked, single-pack Class III membrane, Multithane X delivers exceptional durability, flexibility, and seamless waterproofing — making it one of the most reliable solutions on the Australian market.
Formulated with advanced UV stabilisers and UV absorbers, Multithane X provides superior UV resistance compared to conventional aromatic polyurethane membranes. When used with its compatible topcoat, Multithane ATC, it offers outstanding protection in exposed environments such as roofs, balconies, podiums, and terraces. This long-lasting system ensures stability, performance, and waterproof integrity even under harsh Australian conditions.
At The Waterproof Supplier, we stock Multithane X for best price guaranteed. It meets the highest industry benchmarks, including AS4654.1:2012 for external above-ground waterproofing and Green Star environmental criteria. Whether you’re a builder, waterproofer, applicator, or DIY renovator, this membrane is trusted for its ease of use, reliability, and long-term results.
Designed for efficiency on-site, Multithane X features single-pack technology, eliminating the need for mixing and reducing application errors. Its anti-sag formulation allows application up to 1.2mm and ensures a smooth, self-levelling, 100% bonded membrane with no laps, joints, or weak points. The product will not re-emulsify when cured, is bitumen-free, and will not stain tiles or grout, ensuring a cleaner and more professional finish.
Multithane X is suitable for a wide range of waterproofing applications including balconies, decks, terraces, podium levels, retaining walls, planters, structural slabs, pits, and door flashings. It is ideal for both exposed (with ATC topcoat) and covered areas such as tiled surfaces and landscaped zones. Its mould-resistant formulation makes it a dependable choice for long-term waterproofing in internal, external, above-ground, and below-ground situations.
