Hi, I've recently been put a 1 day online fire door install course from work( I tried getting the 3 day course with 2 day workshop experience) but the course has left more wlquestions than answers. Im really struggling with the 2-4mm spacings. I can get the spacings all the way around the door just fine but when I fit the intumescent the doors won't shut. If I take more of the door there not to regs. Any help will be appreciated. Thanks.
