I live in a victorian house and am wanting to strip back the wooden floor.
The only problem is that there are small gaps between all the floorboards.
What can I do I have seen in some magazines there they put some white
sealant between the boards.

What can I do?

Have you looked at the FAQ?

Another suggestion I've seen is to mix up a filler made from
the sanding dust and a clear setting glue.
