This method works well for substantial gaps. Any smaller gaps (up to 10mm) you could use a foam based floorboard filler on a roll. They do not require gluing etc and are pretty much water tight
We just lifted the carpet in our living room and want to polish the floor boards. How can I fill the gaps between the floorboards? I have tried 'gooey' things in the past but they just came out. I want something fairly solid but elastic that does not make a mess.
Hi
Safelincs does bespoke fire doors to any size. Just state type of finish (wood or paint grade) and size of door leafs (alternatively size of hole in the wall if you want frame as well)
