I have a large 2 panel window with 2 opening sashes. on the transom /upright that seperates the panels and openers there is a crack on the pvcu which is only on the inside skin can I mend this
go to a building plastics supplier and ask for a tube of liquid plastic sealant. clean crack and put sealant into it and wipe off excess. it`s not expensive! also read box which will tell you how long sealant takes to dry
