Material Description
Cafco FENDOLITE® MII is a spray applied, single package
factory controlled premix, based on vermiculite and Portland cement.
Cafco FENDOLITE® MII produces a monolithic coating able
to withstand the thermal shocks experienced in a high intensity hydrocarbon fire. Concrete structures in particular, will be
protected from explosive spalling when coated with Cafco FENDOLITE® MII.
Although low in density, and thus offering significantly reduced dead load, Cafco FENDOLITE® MII is
highly durable and will not crack or spall under mechanical impact.
Cafco FENDOLITE® MII is used for application on construction
elements such as individual steel or concrete sections particularly where off-site application is required. It is also suitable
for use on structures and vessels in the hydrocarbon and power industries.

particularly when the structure is to be fully exposed to the elements. |

Please consult nearest Promat office for specific details related to local, prevalent conditions.
|
|
| Typical substrates |
Steel and concrete |
| Substrate preparation |
The substrate shall be clean, dry and free from visible moisture (including condensation), concrete laitance, formwork
release oils, loose mill scale, loose rust and any other condition preventing good adhesion.
Concrete curing agents should not be used. |
| Mesh reinforcement |
Most fire tests have been conducted without mesh reinforcement, to demonstrate the ability of Cafco
FENDOLITE® MII to stay in place under the most
severe fire conditions. However, for maximum long term in-service durability, the use of lightweight mesh reinforcement
is recommended for exterior work and for interior use where vibration or mechanical damage and the possibility of
subsequent loss of adhesion exist. |
|
|
| Initial steps |
Application of Cafco FENDOLITE® MII must be carried out by an
applicator recognised by Promat. |
| Methods |
Mix Cafco FENDOLITE® MII with potable water in a suitable
mixer and apply by a spraying machine approved by Promat.
Cafco FENDOLITE® MII may also be float or roller-finished
or left with a spray texture.
A hand-applied patching mix is available for minor repairs, i.e. Cafco FENDOLITE® TG. |
| Limitations |
Cafco FENDOLITE® MII may be applied when the substrate and air
temperatures are at least 2ºC and rising, but should not be applied if the substrate or air temperatures are less than 4ºC and
falling. Maximum substrate and air temperature is 50ºC.
Substrate temperature should be at least 2ºC above dew point temperature. |
|
|
|
Top coating |
Under certain circumstances, Cafco top coatings may be used as protection from frequent wash down, long term chemical
spills, or for improved resistance to fungal, algae and bacterial growth. Please consult Promat for details. |
