Self-Adhesive Bituminous Membrane, Self-Protected With Hdpe Cross-Laminated Film, Coupled To A Self-Adhesive Bitumen Mass.

Indextene is a self-adhesive bituminous membrane, self-protected with a cross-laminated high-density HDPE film, coupled to a self-adhesive bitumen mass. The self protection of the cross-laminated high-density polyethylene allows for characteristics of dimensional stability of the membrane and a stable behavior when subjected to elongation both transversal and longitudinal.

Indextene is used to cover flat or sloped areas where the use of open flame is not possible due to the materials or the site.

Indextene may be used to waterproof foundations, basements, insulation systems which do not resist fire or to protect structures from pollutants and salts.

Application

No special tools are needed to apply Indextene – required are a sharp cutting edge, a pair of scissors and a roller.

The roller is used to apply pressure to the material and to the overlaps which must be approx. 6cm longitudinally. An overlap line is indicated on the film 6cm from the edges and 8cm transversally.

For best results, the surfaces must be previously treated with a coat of bitu.®prime primer.

Indextene’s underside is protected by paper. Remove about 50cm of paper at the start of the roll and press the material down onto the surface to be covered. Then, by pulling on the paper and unrolling at the same time, the material can be easily stuck to the working surface.

Indextene should be used in temperatures between 5°C and 45°C. It should not be applied in conditions of high humidity, frost or rain.

Caution

The protective polyethylene film is not UV resistant: it should therefore be protected from the sun within months of application.
