Guest Roger1 Posted March 8, 2021 Report Share Posted March 8, 2021 Hi I have a number of firedoors in a HMO that require a small amount of filling. They are relatively new and structurally in good shape. A previous fire assesment did not call out issues but there are a small number of holes. Im struggling to find Fireproof filler in the usual hardware stores. Does it have to be a specific fireproof filler? Best Quote Link to comment Share on other sites More sharing options...
