Waterproof protection against rain leakage
Heat reflection / temperature reduction
UV resistance
Crack-bridging flexibility
Suitable for concrete roofs, terraces, balconies, parapet walls
Typical application areas:
RCC roof slabs
Metal roofs
Terrace waterproofing
Exterior walls

General application procedure:

Clean the surface completely
Repair cracks and loose areas

Apply second coat cross direction after drying
Allow proper curing

Coverage usually:

Around 400-450 sq.ft per 20 kg for 2 coats (depends on product thickness)

Heat insulation coatings reduce heat transfer but will not cool like an AC.
White or light-colored membranes reflect heat better than dark colors.
Proper surface preparation is critical for bonding and long life.
