Hi Jonny,
First question, has the floor been laid in situ and what are the strips seperated by?
Second question, or is the floor your talking about in actual fact tiles?
Third question, does the floor actually need stripping and re-sealing?
Are you sure you need to do this, if so can you explain whats wrong with the floor?
As Martin has said, it is not an easy process, nor is it quick, but plenty of opportunity to make very expensive mistakes, I can give you guidelines, certainly, but you really do need to know what your doing, regards,
Rob
