MasterEmaco SBR 2 is a milky-white, StyreneButadiene co-polymer latex liquid, produced from
styrene and butadiene by high pressure emulsion
polymerization with high dispersive
properties.When used with cement, concrete and
plaster, it reduces the mixing time through high
dispersion of the polymer and improves
waterproofing, new to old concrete/plaster bonding
and strength characteristics and reduces
shrinkage and cracking of the mix.
RECOMMENDED USES
Concrete repair: Spalled concrete, repairing
floors, beams and pre-cast slabs, chajjas etc.
• Bond Coat: For bonding new concrete to old
concrete, plaster, stone/brick masonry.
• Plaster repair: For repairing plaster or making
water proof plaster which is better than normal
plaster.
• Floor screeds and toppings: Abrasion
resistant and non-dusting floors.
• Waterproofing:Basements side walls and
rafts, lift pits, inspection pits, sunken/overhead
water tank,sunken portions of bathrooms and
toilets, balconies, chajjas, exposed roofs
before finished screed.
• Other typical applications: Bedding tiles,
fixing or re-fixing slip bricks.
