Installation Notes for Aquastop Green Uncoupling Membrane
- Clean and prepare the surface thoroughly before application to ensure optimal adhesion.
- Use with H40 gel adhesives for a continuous protective layer in your tile waterproofing system.
- For external use, apply a finishing coat with H40 adhesive to protect against weather exposure.
- Incorporate movement joints per UNI 11493 guidelines for long-term performance.
- Important: Not suitable for use over anhydrite substrates unless primed with Active Prime Fix. Avoid using on bituminous sheeting, exposed surfaces, inverted roofs, or low-density screeds.
Tile with confidence. Waterproof with assurance. Choose Kerakoll Aquastop Green for long-lasting surface protection and flawless results in your next flooring project.
Frequently Asked Questions About Kerakoll Aquastop Green
What is an uncoupling membrane like Aquastop Green, and why is it needed for tile installations?
An uncoupling membrane, such as Kerakoll Aquastop Green, is a flexible layer installed between the substrate and tiles to prevent cracks from transferring through the flooring. It's essential for areas prone to movement, like balconies or terraces, ensuring durable waterproof tile installations.
Can Aquastop Green be used for outdoor applications like balconies and terraces?
Yes, Aquastop Green is specifically designed for exterior use on balconies, terraces, and flat roofs. It provides waterproofing and stress compensation against thermal deformation, but apply a finishing coat of H40 adhesive for added weather protection.
Is there a waiting period before tiling over Aquastop Green?
No curing time is required. The membrane is walkable immediately after installation and ready for tiling with H40 gel adhesives, speeding up your waterproofing and tiling process.
What adhesives should be used with Aquastop Green for best results?
For optimal performance, pair Aquastop Green with Kerakoll H40 gel adhesives as part of the Laminate No Crack system. This combination ensures high adhesion, crack-bridging, and certified waterproofing under EAD 030400-00-0605.
Is Aquastop Green suitable for wet areas like bathrooms or kitchens?
Absolutely, it's ideal for wet rooms, kitchens, and food production areas. Its breathable yet watertight design manages residual moisture while providing a reliable barrier against water ingress in high-humidity environments.
