Critical Radiant Flux for Sealer of Bare Polished Concrete Floors

The Acceptable Solutions in Chapter 5 give CRF figures for coverings such as carpets and vinyls, and advice on timber floors.

But what about sealed bare polished concrete floors?

Is the issue relevant? or nothing to worry about?

Does anyone have some test figures?

(This question was brought up by a client of mine recently)

While not flooring, BRANZ SR302 (Reaction to Fire of Interior Wall and Ceiling
Linings) has some cone tests of painted concrete. As you would expect it is a brief puff or no ignition at all. None of the flooring tests I have in my archives are of painted or plain concrete.

Thanks Geoff
