![]() | Question: We have use brosteel intumescent (ral 7021) over the top of nullifire on an existing steel. Is there any problem in doing this, are the products compatible Regards Dave |
Answer from Rawlins’ Technical Team: If another intumescent coating has been applied over Nullifire S605 Durable Solvent-Based Intumescent Coating, we would not be able to recommend this practice. We would not be able to confirm how the Nullifire product would react under fire conditions. The new intumescent could swell and remove the Nullifire coating, or the Nullifire coating may swell first and push off the competitor intumescent which may also cause possible delamination of the char from the Nullifire material. We would have to recommend full removal of the Brosteel then the DFT of the Nullifire coating should be checked to ensure the correct amount of intumescent is still applied to the structural steelwork. | |
