Description

When the programme is tight and you need to tile the same day, SUBSTRAT SealCoreX 2 Part Rapid is the tanking membrane that keeps you moving. This two-component, self-crosslinking waterproofing system reacts and sets fast, curing rapidly without shrinkage or cracking, even where there is no exposure to air, so you spend less time waiting between trades.

Key features

  • Two-component, fast-curing reactive system in an 8kg pack
  • Cures quickly without shrinkage or cracking, so you can tile over sooner
  • Forms a continuous, fully waterproof under-tile barrier on walls and floors
  • Highly flexible once cured, accommodating structural movement without de-bonding
  • Excellent adhesion to mineral substrates and fleece-backed membranes; made in Germany

Use it to tank shower enclosures, bathrooms and wetrooms before tiling wherever speed matters most. It is part of the complete, certified Substrat wetroom system, and is a rapid-cure alternative to the single-component SUBSTRAT SealCoreX Ready Mixed Tanking Membrane — choose whichever application method suits the job.

Full System Guarantee. SUBSTRAT SealCoreX is the waterproof heart of the Substrat wetroom system. Installed together with the matching Substrat detailing — ButylX Pro, ProfiX Pro, FleeceX Pro, FleeceXL Pro and CutX Pro tapes, corners and collars — it forms one continuous, certified barrier. Using the complete, matched system is what qualifies your project for the Substrat Full System Guarantee.
