Description
Get a fully sealed wetroom without the hassle of on-site mixing. SUBSTRAT SealCoreX Ready Mixed is a single-component tanking membrane that arrives pre-blended and ready to use straight from the tub, so you simply open, stir and apply. This grey, brush- or roller-applied waterproofing forms a continuous under-tile barrier across walls and floors before you set a single tile.
Key features
- Single-component, ready-mixed formula with no measuring or mixing on site
- Apply by brush or roller to walls and floors in two coats, the second at right angles to the first
- Cures to a permanently flexible, elastic barrier that absorbs normal structural movement without cracking or de-bonding
- Excellent adhesion to mineral substrates
- Available in 6kg and 14kg tubs; made in Germany
Ideal for tanking showers, bathrooms and full wetrooms prior to tiling, it forms part of the German-made, certified Substrat wetroom system. Fitting over a timber or heated floor? Pair it with the SUBSTRAT DecoupleX Anti-Fracture Membrane for reliable stress relief beneath your tiles.
