MasterCast 141 is a white liquid (SBR) styrenebutadiene co-polymer latex, specifically designed
for use with Portland cement mixes. The latex
consists of microscopic particles of synthetic
rubber dispersed in an aqueous solution. It is used
as an admixture in mortar and concretes to
improve compressive and flexural strengths,
improve bond increase resistance to water
penetration, improve abrasion resistance and
durability. It is used with Portland cement as a
reliable water-resistant bonding agent.


The use of MasterCast 141 synthetic latex in
cement-based slurries and mortars compensates
for many deficiencies in the mixes without
detracting from their inherent strength and
properties. As ordinary mortar dries out, voids are
created which make it permeable and weaker.
When MasterCast 141 is added, the MasterCast
141 particles bind together to form continuous
films and strands - these bind to the sides of the
voids and block up the capillary pores, thus
increasing strength and resistance to water
MasterCast 141 improved mortars are
especially suited for the following:
 Concrete repair.
Repairing spalled, cracked or damaged
concrete, floors, beams, columns and precast
 Corrosion protection of reinforcing steel.
As a bonding slurry or steel primer in concrete
 Floor screeds and toppings.
Producing abrasion resistant and mild
chemical and effluent-resistant, non- dusting
floors, and underlays for special finishes,
coatings and toppings.
 Waterproofing and tanking.
Basements, lift pits, inspection pits, water
towers, liquid tanks, effluent tanks and
swimming pools.
 External rendering.
Waterproof, weatherproof and frost resistant
 Fixing slip bricks and tiles.
Bedding tiles, fixing or re-fixing slip bricks,
bonding new concrete to old.
 Polymer modified concrete.
Production of Polymer Modified Concrete
according to ACI 548.3
 Light Weight EPS bead concrete.
Mix stabilization and cohesion improver to
reduced surface EPS bead loss.
 Earlier hardening
