Hi everyone,my appologies if this has been covered elsewhere. I have a lot of nominal fire doors with gaps around them more than 4mm meaning i can't get a cold smoke seal with my intumescent brush strips. The doors are a flush veneer faced door with a chipboard core.i was wondering if anybody knew if i would be ok to re edge them with hardwood lipping or if it is a no no due to the core of the door? I m sure it isn't a problem re edging solid timber core doors
Thanks
