BITUSTIK – Self-Adhering Waterproofing Membrane

Description:

BITUSTIK is a self-adhering waterproofing membrane made of distilled bitumen modified with SBS (styrene-butadiene-styrene) polymers. It features an adhesive coating on the lower face and a self-protecting upper surface with either sand (BITUSTIK 2.0 mm) or plastic PE film (BITUSTIK 1.5 mm).

The carrier is a composite polyester stabilized with longitudinal glass yarns, providing superior dimensional stability, good tensile strength, elongation values, and excellent mechanical properties.

Available Surface Finishes:

Upper Surface: Sand (BITUSTIK 2.0 mm) or plastic PE film (BITUSTIK 1.5 mm).
Lower Surface: Silicone release film.

Storage: Store in a dry, cool place away from direct sunlight and frost.

Use For: BITUSTIK is recommended as an underlayer in multilayer systems or as a waterproofing layer below roof tiles or on pitched roofs where the use of an open flame is not permitted or advisable. This is particularly useful over wooden decks or fire-sensitive insulation layers. BITUSTIK offers a fast and safe application, saving time during the waterproofing process.

Health and Safety Information:

Ecology: According to local law.
Transportation: Non-hazardous.
Toxic: Non-toxic.
