FEATURES Toa 237 Cement Membrane is a cement based 2 parts polymer modified waterproofing slurry. It is applied on surface of concrete or mortar to prevent or solve the problem of leakage of the structure. Due to flexible in itself, it is not a problem to crack. Suitable for waterproofing, cracksealing and repair works.
APPLICATION SYSTEM Surface Preparation
Substrate must be sound, free of loose or weak particles, dust and dirt. Oil and wax containing layers, as well as laitance must be completely removed. The substrate must be thoroughly wetted down prior to the mortar application.
In case of mold and algae, brush and clean with TOA 113 Microkill then leave it dry for 24 hours before applying with TOA 237 Cement Membrane.
Mixing
Pour Part A, Acrylic polymer, size 6 kgs. Into a prepared container. Add Part B, Modified portland cement, into the container gradually while using a blender mixing with a low speed and mix for approx. 3 minutes until a smooth workable consistency is achieved.
Application
Apply the first coat while the surface is still damp from saturation with an iron trowel or brush and leave to harden ( 3-6 hrs. ).
Apply a second coat of identical thickness at the rate 1.5 - 2 kg / 1 sq.meter / 1 coat but coat in the direction transverse to the first coat.
