Application

  • For internal use.
  • Suitable for application to non-primed and primed steel and concrete frames, metal floor or roof decks, and return air plenums. It may be easily removed and reinstated locally when additional fixings are required.
  • Building types include a wide range of educational, leisure and entertainment centres, commercial or industrial projects.
  • The use of lightweight mesh reinforcement is recommended where vibration or mechanical damage and the possibility of subsequent de-bonding exist.

Description

A spray applied, single package factory controlled premix, based on vermiculite and Portland cement, for internal use.

Produces a monolithic coating able to withstand the thermal shocks experienced in a high intensity cellulosic fire. Concrete structures in particular, will be protected from explosive spalling when coated with Cafco MANDOLITE® CP2.

Features and benefits:

  • 30–240 minutes' fire resistance.
  • Part of a Promat steel protection system.

Fire protection:

Structures protected with the product have undergone extensive fire resistance tests up to 240 minutes in approved independent laboratories to recognized standards, including:

  • UK: consult manufacturer for details.
  • USA: ASTM E119 UL263.
  • Germany: DIN 4102:1977-09 and DIN EN 1363-1:1999-10.
  • The tests also comply with ISO 834.
  • The tests also comply with ISO 834.Protected structures have been successfully tested under BS 476-21 to failure temperatures of up to 800°C. This allows the specifier the freedom to adopt a fire engineering approach to fire resistance in accordance with BS 5950-3 and -8, as well as the Fire Appendices of the Eurocode.
  • The fire resistance test results relate solely to the constructions tested and test conditions imposed. The manufacturer provides computer based thickness calculations to meet specific fire resistance requirement.

- Product thickness:

  • The thickness of the fire protection for a given period of fire resistance in a cellulosic type fire relates to the exposed surface area-to-volume (A/V) ratio of the section.
  • All column and beam sections have their own specific A/V ratio. Consult manufacturer to establish the A/V ratio for a particular beam or column section. Consult manufacturer's literature to ascertain the thickness necessary to meet the required period of fire resistance for I-section beams and H-section columns.

For advice on thickness calculations for hollow sections, cellular beams, castellated sections, composite floors, upgrading of concrete slabs and more complex situations, contact manufacturer's Technical Services department.

Application:

  • For internal use.
  • Suitable for application to non-primed and primed steel and concrete frames, metal floor or roof decks, and return air plenums. It may be easily removed and reinstated locally when additional fixings are required.
  • Building types include a wide range of educational, leisure and entertainment centres, commercial or industrial projects.
  • The use of lightweight mesh reinforcement is recommended where vibration or mechanical damage and the possibility of subsequent de-bonding exist.

General information

Finish

Monolithic spray texture

Features

It produces a monolithic coating able to withstand the thermal shocks experienced in a high intensity cellulosic fire. Concrete structures in particular, will be protected from explosive spalling when coated. Although low in density, thus significantly reducing dead load, it is highly durable and will not crack or spall under mechanical impact

Material

Premix, based on vermiculite and Portland cement

Shape

Formless, wet mix spray

Size

8 mm thickness when unreinforced, 13 mm when reinforced
