NEOPROOF PU 500 is a Water based, High Performance, Polyurethane Modified UV stable, cold applied flexible liquid waterproofing membrane. Its ecofriendly unique formula makes it a proven & durable solution for weatherproofing, waterproofing applications. PU 500 cures to a permanently flexible seamless membrane with excellent adhesion to a wide range of substrates. Unlike traditional bitumen based products it does not embrittle upon ageing or on exposure to ultra violet radiation or weathering. Being flexible, NEOPROOF PU 500does not crack or get affected by variations in temperatures.

 

APPLICATION AREA

NEOPROOF PU 500 is suitable for use on many porous substrates including Gyprock, fibre cement, concrete, render brickwork, render and plasterboard. The product finds use in waterproofing of basements, kitchens, bathrooms, balconies and decks, shower recesses, repair and restoration of leaking roofs as well as a damp proof membrane in sandwich panel construction. It is also suitable for use in Deck areas & can be used in planter boxes and retaining walls as long as it is protected suitably.
