Ensure a continuous, watertight seal at critical junctions with Mapeguard ST—the specialist sealing tape designed for use within the MAPEI Mapeguard WP waterproofing membrane system. This high-flexibility, self-adhesive tape bridges transitions between floors and walls, and seals overlaps between membrane sheets, preventing water infiltration at the most vulnerable points.

Why Choose Mapeguard ST?

• Perfect Integration: Specifically engineered for seamless compatibility with Mapeguard WP 200 membranes.

• Strong & Flexible: Accommodates substrate movement while maintaining a durable, watertight seal.

• Easy to Apply: Self-adhesive backing ensures quick and secure installation.

• Essential for System Integrity: Closes gaps at wall-to-floor junctions and sheet overlaps, eliminating weak points in the waterproofing layer.

Ideal For:

• Sealing junctions between floors and walls in showers, bathrooms, wet rooms, and balconies

• Waterproofing overlaps between sheets of Mapeguard WP 200 membrane

• Reinforcing internal corners and transitions within the waterproofing system

• Use in combination with Mapeguard IC/EC corners and Mapeguard PC pipe collars

How to Use:

1. Install Mapeguard WP 200 membrane over the primed substrate using approved adhesive.

2. At junctions and overlaps, apply Mapeguard ST directly onto the membrane.

3. Press firmly along the entire length to ensure full adhesion and a bubble-free seal.

4. Continue with the installation of tiles, stone, or LVT as per system guidelines.
