Lorient Fire Only Seal 10x4mm White (Pack of 100)

Fire Only Seals:
There is no evidence to suggest that overpainting of intumescent fire seals has any detrimental effect on the ability of the seals to perform efficiently.
However, overpainting should be avoided wherever possible, or if unavoidable should be limited to a maximum of five coats of conventional oil bound paint or varnish on the strip without damaging its effectiveness, or a maximum of 0.5 mm, whichever is the greater.

Smoke Only or Fire and Smoke Seals combined:
It is of the utmost importance to ensure the flexible element of any smoke fin or brush is not painted as this will impede flexibility and subsequently their performance.
