Silver Composite Aluminum Foil Butyl Rubber Waterproofing Membrane Tape For Concrete Cement Roofs

Butyl rubber waterproof tape, used for concrete/cement roofs

Product Features:

The adhesive layer has sufficient thickness, shows good wettability to uneven cement base surfaces has strong adhesive force, can adapt to subtle deformation of the base surface, and has long-lasting sealing effect.

Base surface adaptability: Designed with a thick adhesive layer, it can fill the fine and air holes on the cement base surface, has extremely strong conformability to uneven base surfaces, and no additional leveling treatment required. Adhesion strength: The measured peel strength is ≥0.5kN/m, which bonds firmly with the cement base surface and will not off due to slight sanding on the cement surface layer. Deformation resistance: With an elongation rate of over200%, it can adapt to the fine cracks caused by temperature difference deformation of the cement roof and will not torn. Weather resistance: Strong in ozone resistance and rain wash resistance, it will not become brittle or crack after long-term use in environments.

Construction Steps:

 1. Base Treatment: Use a brush to sweep away floating and sand on the cement base; first fill and grind the cracks and recesses with cement mortar, then dry the base with hot air gun until the moisture content is below 8%. 2. Preaying Positioning: Mark the tape laying path in advance on the area to be waterproofed; reserve a lap of ≥5cm when splicing multiple sections, and pre-cut 45° pre-notches at special-shaped internal and external corners. 3. L and Compaction: After peeling off the release film, lay the tape aligned with the marking lines; use a squeegee to push air out from the middle of the tape to both sides, ensuring the tape is fully to the cement base without empty drums. 4. Final Protection: 24 hours after the completion of pasting, cover the surface of the tape a 2cm-thick cement mortar protective layer to avoid accelerated aging due to long-term direct exposure to ultraviolet rays.
