Mapei Mapeguard ST Sealing Tape, Corners & Gaskets are part of the Mapeguard Waterproofing System. Mapei Mapeguard ST Sealing Tape, Corners & Gaskets are designed to be used with Mapeguard WP 200 – an alkali-resistant, waterproofing and anti-fracture membrane for waterproofing wet and damp areas in residential and commercial buildings, such as bathrooms, wet rooms, showers and more.
Mapei Mapeguard ST Sealing Tape is a 3-ply polypropylene/polythylene waterproof sealing tape that is to be used for sealing wall and floor junctions and joints between sheets of Mapei Mapeguard WP 200 Membrane, with Mapeguard WP Adhesive. This tape comes in 120mm x 10 metre rolls. The internal and external corner pieces are for sealing internal and external corner junctions where the walls meet the floor, and the pipe gaskets are for sealing around pipes that are protruding through the walls, such as water pipes. The pipe gaskets are available in 3 sizes for a range of pipe diameters: 10-24mm, 15-38mm and 28-50mm.
Installation with Mapeguard WP 200:
The membrane must be cut to size before being bonded. Use a tile adhesive conforming to a minimum of class C2 according to EN 12004 or ISO 13007 (such as Keraquick S1, Ultralite S1, Keraflex, Keraflex Maxi S1 or similar) using a 3×3 or 4×4 mm notched trowel. If LVT flooring is to be installed afterwards, bond the membrane with Mapeguard WP Adhesive.
For application details please refer to the pertinent technical data sheet. Mapeguard WP 200 Membrane must be laid over the fresh adhesive and pressed down uniformly, from the centre to the edges, in order to avoid trapping air bubbles under the waterproofing membrane.
The overlap between membrane sheets must be minimum 5 cm wide and must be sealed with Mapeguard WP Adhesive applied with a 3×3 mm notched trowel. Seal all the junctions between floors and walls and between adjoining sheets with Mapei Mapeguard ST Sealing Tape, laid directly onto the membrane joints with Mapeguard WP Adhesive.
Waterproof the internal and external corners with Mapei Mapeguard ST Internal and External Sealing Corners, bonded with Mapeguard WP Adhesive onto the membrane. All pipes must be waterproofed by using the special Mapeguard ST Sealing Pipe Gaskets bonded with Mapeguard WP Adhesive on the membrane. Before installing the membrane, Mapeflex MS45 must be applied around the perimeter of the drain in order to achieve an adequate seal to the junction.
