GacoFlex NF-621

Gaco Western Field Curing Neoprene Sheet is a specially formulated neoprene elastomeric material that cures in place to form a durable, watertight membrane with excellent resistance to naturally occurring ultra-violet light and ozone, temperature variations, weathering, and most chemicals.

USAGE

Excellent for flashing and expansion joints on built-up or elastomeric roofing systems, decks and below grade or between slab waterproofing membranes. Appropriate for installation wherever the roofing or waterproofing membrane terminates at walls, parapets, curbs, expansion joints, penetrations, protrusions or where one roofing system ties in to another.

STORAGE

Store in an area maintained at a temperature between 50º F (10º C) and 75º F (24º C), out of direct sunlight or exposure to adverse weather conditions. Do not place near excessive heat, sparks, or open flame. Field curing neoprene sheet has a shelf life of approximately 90 days during which it remains conformable to irregular shapes.

APPLICATION

Field curing neoprene is highly pliable allowing ease of application to most shapes and irregularities and thus curing to shape. It may be applied with contact adhesive to concrete, masonry, metal and wood to form a permanent waterproof bond. It can be bonded to elastomeric roofing and waterproofing membranes with Gaco Western contact adhesive or hot mopped into conventional built-up roofing with hot bitumen.
