Armourshield

Description

TorchShield APP membrane

CHRYSO ARMOURSHIELD-S membranes are factory fabricated waterproof sheets of predetermined thickness. These sheets are also known as APP (Atactic Polypropylene) membranes, consisting of a specially formulated bituminous compound of distilled asphalt modified with selected high grade visco-elastic polymers (APP), stabilizers and inert fillers, reinforced with a robust, non-woven polyester reinforcement.

The top surface of the membranes is covered with thin layer of PF film, sand or mineral protection. The bottom surface is covered with Flam-O-Lene (Flammable PE Film). For exposed applications, the top surface is covered with a layer of natural slate flakes (mineral) to protect the membrane from UV rays and physical damage.

Priming

The cleaned concrete surface must be coated with BITCOTE PRIMER (heavy bodied bitumen sealer cum primer) which is compatible with the membrane. The primer must be spread evenly and allowed to dry completely. Only the area to be waterproofed on a given day should be coated with primer.
