Spectite HP 600
One part polyurethane elastomeric membrane
DESCRIPTION
Spectite HP600 is a black, liquid applied, pitch modified, high polymer, one part polyurethane, which cures upon exposure to atmospheric moisture to form a tough, flexible and elastomeric membrane with excellent water resistance and low vapour permeability.
TYPICAL USES
To provide a waterproofing membrane to building and civil engineering structures in a variety of situation such as:
- Tiled floors in bathrooms, shower rooms, kitchens and plant rooms
- Foundations and basement structures
- Suspended floors, parking decks and promenades over utilized areas
- Balconies, roof terraces, patios and planter boxes
- Inverted roofs
- Non potable water retaining structures, sewage tanks, inspection pits and tunnels.
ADVANTAGES
- Single component which requires no mixing or heating
- Excellent adhesion to most common construction substrates
- Highly flexible with excellent crack bridging properties
- Good application characteristics by brush or spray.
- Excellent water resistance and low vapour permeability
- Does not readily embrittle with age when exposed to UV radiation or weathering- U.V.resistant grade available
- Resistant to cracking at low temperatures and does not suffer flow at high temperatures
- Good resistance to industrial environments.

APPLICATION
Preparation
Concrete surfaces must be float or shutter finished.
The surfaces must be free of cavities and projections. Blockwork or brickwork must be flush pointed and of a uniform finish.
The surfaces should be made dry, clean, dust and frost free to expose a sound, clean substrate.
Priming is not normally necessary on good quality concrete, however for particularly porous or metal surfaces, Spectite Primer 60 must be used.
Spectite Hp 600 should be applied after the primer has become tacky, usually 2-4 hours following applicaton, but before it has fully reacted.
If the Spectite Hp 600 is not applied within 48hours after priming, the surfaces should be re-primed.
Application
The first coat should be applied by brush,roller or airless spray equipment at a dry film thickness not less than 0.5 mm or more than 1 mm per coat.
The first coat should be touch dry prior to the applicaton of the second coat. When continuing membrane application from day joints, an overlap of 250 mm should be made.
Spectite HP 600 can be coated over or granules can be broadcast as desired
Protection
In certain conditions, particularly where back filling against Spectite HP 600 is anticipated, protection board such as Spectite PBP or PBF should be used.
Storage and shelf life
Spectite Hp 600 has a shelf life of 12 months when stored in orginal containers in cool, dry conditions.
HEALTH & SAFETY
Spectite HP 600 and Spectite Primer 60 avoid contact with skin and eyes, wear gloves and eye protection.
