Damage to FIRETEX
Where FIRETEX coatings have been damaged due for example to transportation, erection or site trades, then the best practice should be that ALL such areas of damage must be repaired.
Clearly in reality, there will be many occasions where there are only isolated small chips which would be covered by the surrounding intumescent in the event of a fire. So our opinion on such occasions would be not to carry out repair unless aesthetics or prevailing site conditions demanded it.
A small chip can be classed as up to the size of a £1 coin and this should be no more than 1% in any area – this roughly equates to damage equivalent to the size of a £1 coin in an area the size of an A4 piece of paper.
