Outstanding elongation and recovery, 700% elongation, 96% recovery
Compatible with both tar and bitumen
Durable long lasting protection
Superior protection over holes, cracks and splits.
DESCRIPTION
Polyroof is a high performance, one part elastomer for critical roof areas subject to considerable movement.
USAGE:
Patch up holes, cracks, splits in bituminous roofs
Sealing of insulation breather vents
Build up of ponding water areas
Sealing of moving joints
Sealing of gravel stop lap joints
Metal edges
Sealing of membrane flashings
General roof repair
Suitable application onto flat, pitched or vertical surfaces.
LIMITATIONS:
Do not use over loose gravel.
COLOURS:
Black
PACKAGING:
300ml cartridges 30 per carton, 22.7 Litre pails.
COMPOSITION:
Polyroof's unique formulation of elastomers, plasticers and selected additives is formulated to ensure high elasticity coupled with long lasting service, specifically developed to repair moving joints, metal edges. As a rubbery, highly flexible roof patching elastomer it affords superior protection over holes, cracks and splits, ponded water areas, ridges and for installing insulation breather vents.

SURFACE PREPARATION
Remove dust, loose gravel and torn felts. Sweep away ponded water. Apply over a clean, sound, dry base.
APPLICATION
By trowel.
For Membrane Flashings:
Apply a minimum of 3mm thickness 100mm-200mm onto the deck, 25-50mm above existing flashing.
For Gravel Stops:
Directly over all lapped metal joints or where extreme movement can be expected, apply 13-20mm wide strips
of bond breaker tape. Then apply Polyroof at 13mm thickness over the bond breaker tape and for at least
25mm beyond its perimeter. Apply at 6mm thickness throughout the remaining roof edge.
Valleys and Ponded Areas:
Protective coatings in these areas are usually subjected to rapid deterioration, particularly on build up of bituminous roofs. Polyroof will provide long lasting protection by applying 3-5mm thickness to such areas including the vertical projections subjected to standing water.
Splits and Holes:
Apply a minimum thickness of 6mm over splits or holes and tape the Polyroof down to the roof membrane, lapping at least 50mm on all sides.
COVERAGE
Rates will vary depending upon actual surface conditions. Minimum 3mm thickness over smooth surface - 0.2m2 per litre approximately.
CLEAN UP:
Mineral Turpentine or Xylol.
HEALTH AND SAFETY PRECAUTIONS
Hazardous according to Worksafe Criteria.
Always provide adequate ventilation. If mechanical, use explosion proof equipment Do not get on skin.
Material Safety Data Sheet must be read and understood before use.
STORAGE
Store in dry conditions between +5oC to +40oC.
SHELF LIFE
12 months as stored as above in original unopened container
.
