Promat Q&As

What is the minimum distance between services and the edge of the seal, if using PROMASEAL® Fire Compound Extra Strength

We would typically recommend minimum 50mm between services and the edge of the seal, to allow the compound to flow into the gap and to form a complete seal, with no air entrapment.

It is recommended that the compound should be poured slowly into the opening, to allow it to flow into the gaps, without creating turbulence.  See our product data sheet for further information
