One-part pitch-modified polyurethane elastomeric membrane.

Application of SPECTITE HP600:
Surface Preparation:
Concrete surfaces must be float or shutter finished. The surfaces should 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 Application:
Priming is not normally necessary on good quality concrete; however, for particularly porous or metal surfaces, SpECtite HP600 Primer must be used. SpECtite HP600 should be applied after the primer has become touch dry, usually 2-4 hours following application, but before it has fully reacted. If the SpECtite HP600 is not applied within 48 hours after priming, the surfaces should be re-primed.
Coating Application:
SpECtite HP600 should be applied by brush, roller, or airless spray equipment at a thickness of 1mm in two coats. On vertical surfaces, it may be necessary to achieve the correct film thickness by applying two coats with lighter loading to avoid slump, especially when working at a high ambient temperature. Apply 2 coat systems at right angles to each other to ensure an even coating application. If a flood test is to be done, allow a minimum curing period of 10 days. The first coat should be touch dry prior to the application of the second coat, which should be applied within 12 hours of the first coat becoming touch dry.
Repairs:
Minor damage to SpECtite HP600 can be repaired by:
• Removing loose membrane
• Cleaning the surrounding area, overlapping by 150mm
• Priming the cleaned area with SpECtite HP600 Primer and applying 2 coats of SpECtite HP600
