Cafco FENDOLITE® TG - Vermiculite Cement Based Wet Mix Trowelled Coating
INTRODUCTION
Cafco FENDOLITE® TG is a trowel applied, factory controlled premix based on vermiculite and Portland cement. It is used with potable water added on site.
Cafco FENDOLITE® TG will not fail suddenly after the prescribed fire resistance period but will continue to offer a predictable level of fire protection for the duration of the fire.
Cafco FENDOLITE® TG is ideal for application by trowel in interior and fully exposed environments.

ADVANTAGES
- Structures protected with Cafco FENDOLITE® TG can provide fire resistance for up to 240 minutes.
- Cafco FENDOLITE® TG is applied by plastering techniques enabling repairs to be completed without the need to introduce spray plant onto the site.
- The effectiveness of Cafco FENDOLITE® TG will not be impaired or destroyed by the effects of water impingement/thermal shock from fire hoses or sprinkler systems. It will remain in place and not be affected by wind turbulence.
- Resistant to impact damage, therefore able to meet the specification within environments where durability is essential.
- May be levelled to present a trowelled finish.
- Can be easily removed and reinstated locally when additional fixings are required.
| Preparation |
| Typical substrates |
Existing Cafco FENDOLITE® MII, concrete, unprimed and primed steel. Concrete curing agents should not be used |
| Substrate preparation |
The substrate must be clean, dry and free from visible moisture (including condensation), concrete laitance, formwork release oils, loose millscale, loose rust and any other condition preventing good adhesion
Any other priming systems must be compatible with an alkaline pH of 12.0-12.5
|
| Application |
| Limitations |
Cafco FENDOLITE® TG 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 45ºC
Substrate temperature should be at least 2ºC above dew point temperature
