Schlüter KERDI 200 Waterproofing Membrane Range
The Schlüter KERDI 200 range is a professional-grade bonded waterproofing and vapour-retardant membrane system, engineered for superior moisture protection beneath ceramic tiles and natural stone. Constructed from durable polyethylene (PE) with fleece webbing on both sides, it ensures strong adhesion with thin-bed tile adhesives and long-term waterproof reliability across walls, floors, and other wet area installations.
Available Variants
- KERDI 200 (1 m width) — Perfect for smaller walls, niches, and detailed installations
- KERDI 200 200 15 (2 m width) — Ideal for large wall areas and fast, joint-free coverage
Both variants provide identical waterproofing strength and flexibility. The difference lies only in the width and surface coverage, allowing installers to choose the most efficient format for their project.
Key Benefits
- Complete waterproof and vapour-retardant protection for wet areas
- Crack-bridging and flexible, ensuring long-lasting durability
- Lightweight and easy to cut, fit, and install
- Compatible with Schlüter-KERDI-KEBA, KERDI-COLL, and KERDI-BOARD systems

Frequently Asked Questions (FAQs)
What is the difference between KERDI 200 and KERDI 200/15?
Only the width differs. KERDI 200 is 1 m wide, ideal for compact areas, while KERDI 200/15 is 2 m wide for larger surfaces. Both deliver identical waterproofing and durability.
Can KERDI 200 be used with underfloor heating?
Yes. It’s compatible with heated flooring systems when installed following Schlüter guidelines, providing excellent thermal and moisture protection.
Is KERDI 200 fully vapour-proof?
It’s classified as vapour-retardant (SD ≥ 5 m), suitable for standard wet rooms and bathrooms. For steam rooms, consult Schluter’s technical documentation.
Which adhesive should be used?
A high-quality, cement-based thin-bed tile adhesive is recommended. Avoid solvent or dispersion-based adhesives.
Do I need any special tools for installation?
No — regular tiling tools such as a notched trowel, roller, and utility knife are sufficient for a professional result.
