|
|
|
|
|
| Surface preparation |
Concrete surfaces should
be clean, sound and free from oilgrease, cement |
|
|
|
|
|
laitance and all loosely
adhering particles. |
|
|
|
|
|
|
|
|
Absorbent surfaces should
be saturated thoroughlybut no ponding. |

|
|
|
|
| Materials |
|
|
Aggregates should be well
graded and thoroughly washed,Sand particle |
|
|
|
|
|
size should correspond to
the thickness of mortar to be applied and required |
|
|
|
|
|
surface finish. |

|
| Dilution Rates |
|
Superbond Latex is
generally added to the clean mixing water within the range |
|
|
|
|
1:1 - 1:4 For all
applications apart from sprayed on renders a bonding coat |
|
|
|
|
|
of Superbond Latex -
water 1:1 mixed with fresh cement should be brushed into the |
|
|
|
|
prepared surface. |
|
|
|
|
|
|
|
|
|
|
Subsequently morta
application must be carried out whilst the bonding coat |
|
|
|
|
|
is still wet. |

| Important Recommendation |
1. never use Superbond
Latex and water as a bonding coat without adding |
|
|
|
|
|
cement (and fine sand). |
|
|
|
|
|
|
|
|
|
2. Proper curing method
is needed |
|
|
|
|
|
|
|
|
3. Always prewet the
absorbent substrate but no ponding |
|
|
|
|
|
|
4. Multi-lay work always
wet on wet |
